BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a cellular phone having a function of taking pictures.
2. Description of the Background Art
In recent years, cellular phones have been widely used. Shapes of such cellular phones can be roughly divided into three types, i.e., a straight type, a flip type and a clamshell type. Among them, the cellular phone of the clamshell type can be small in size when it is folded so that the needs for it are higher than those for the other types.
Recently, such a cellular phone has been proposed that is provided with a liquid crystal sub-display on a rear surface remote from a main liquid crystal display, and also a cellular phone having a camera function has been proposed.
An open/close detector 109 is a detecting portion for detecting whether cellular phone 100 is in a folded state or not. A small projection 109a is formed at a lower portion of first body 101 near hinge 103, and a small aperture 109b is formed at an upper portion of second body 102 near hinge 103. A detection switch (not shown) is arranged within aperture 109b. Open/close detector 109 includes projection 109a, aperture 109b and the detection switch. When cellular phone 100 is folded, projection 109a on first body 101 enters aperture 109b at second body 102, and thereby activates the detection switch (not shown) so that a control portion arranged within the body determines that cellular phone 100 is folded.
Description will now be given on second body 102 of conventional cellular phone 100. An input button portion 110 includes keys for entering numbers and letters. A function button group 111 is a group of buttons for achieving various kinds of setting and function selection in the cellular phone. A power button 112 for power-on/off, a first shutter button 113 for a camera function, which will be described later, a mail/guidance button 114 for a mail function and guidance display, a start and speaker-receive button 115 for starting a call and speaker-receiving, and a multi-guide button 116 formed of a four-way button and a decision button, which are used for performing up/down and right/left selection as well as decision on a function selecting screen. Second body 102 is provided at its lower portion with a conversation microphone 117.
In the conventional cellular phone, hinge 103, function button group 111, input button group 110 and conversation microphone 117 are successively arranged on second body 102.
Second display portion 120 is arranged to occupy an outside position when cellular phone 100 is in the folded state. Second display portion 120 (sub-display) comprises a liquid crystal display or an EL display. Second display portion 120 displays images based on image data sent via a second display driver portion arranged in the body.
Camera portion 121 includes imaging lenses, an imaging element such as a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor, and RGB (i.e., tricolor) color filters. In camera portion 121, the color filters produce tricolor light of RGB from the light, which are reflected by a subject and are transmitted through the imaging lenses. As shown in
Light portion 122 is used as an auxiliary light source when taking images by camera portion 121. In general, many kinds of conventional auxiliary light sources employ xenon tubes. In recent times, however, some kinds of auxiliary light sources employ red, green and blue LEDs, which are simultaneously turned on to emit while light.
Second body 102 is provided at its rear surface with a battery portion 123 for holding a battery and a second speaker 124 for playing a ringing tone.

BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention will now be described with reference to the drawings.
Referring to
Description will now be given on second body 3 of cellular phone of an embodiment of the invention. Second body 3 comprises an input button group 7 formed of keys or the like to be used for entering numbers, letters and others, a function button group 8 for performing various kinds of setting and function selection in cellular phone 1, a power button 9 for power-on/off, a first shutter button 10 to be operated for enabling a shutter function, a mail/guidance button 11 for selecting a mail function and performing guidance display, a start/speaker-conversation button 12 for starting a call and performing conversation via the speaker, and a multi-guide button 13 having a four-way button and a decision button for performing longitudinal and lateral selection on a function select screen and for deciding the selection. These buttons can be operated by a user. Further, second body 3 is provided at its lower portion with a microphone 14.
Usually, hinge 4, function button group 8, input button group 7 and conversation microphone 14 are arranged in this order on second body 3 of cellular phone 1. However, the order is not restricted to the above.
As shown in
Second display portion 20 is arranged to occupy an outside position on the body of cellular phone 1 in the folded state. The second display portion 20 comprises a liquid crystal display, an EL display or the like. In this embodiment, second display portion 20 has a display region smaller than that of first display portion 5. However, the display region of second display portion 20 may be larger than or equal to that of first display portion 5. Second display portion 20 displays images based on image data, which is obtained by photographing and is provided via a second display driver portion 44 to be described later, and also displays images based on data of character images for informing the user of a time, a radio wave intensity, a mail reception and others.
As described above, each of first display portion 5 and second display portion 20 is arranged at the surface of first body 2 or second body 3, which is exposed externally in the open or unfolded state, with the display screen directed externally. In particular, second display portion 20 is arranged at the surface, which is exposed externally, of first body 2 or second body 3 in the folded state such that second display portion 20 is directed externally in the folded state.
For displaying images, second display driver portion 44 sends the image data to second display portion 20, and the image based on the image data is displayed such that an upper side of the image is located near hinge 4. Since second display portion 20 displays the image such that the upper side thereof is located near hinge 4, the user using cellular phone 1 in the folded state locates hinge 4 in the upper position so that the direction of second body 3 does not change when the user changes the state of cellular phone 1 between the open state and the closed state. In other words, the user is not required to change the direction or position of cellular phone 1 on the user's hand each time the user opens or closes cellular phone 1. Consequently, operability and convenience are improved. The images displayed on second display portion 20 include images taken or obtained by shooting. Therefore, the user can view such taken images without the necessity of changing the direction or position of cellular phone 1 on the user's hand. This improves the operability and convenience.
As described below, the antenna is arranged in a position other than a conventional position, i.e., a position on a rear surface of first body 2. This eliminates or reduces restrictions on the rear surface of first body 2 so that second display portion 20 can be larger in size than that of a conventional structure. Accordingly, it can display a larger amount of information such as text and taken images. Further, cellular phone 1 includes a second operation button group 24. Therefore, even when cellular phone 1 is in the closed state, the user can operate cellular phone 1 to display various images on second display portion 20 for checking contents of mails, referring to an address book or successively displaying a plurality of images. The images displayed on second display portion 20 include taken images, i.e., images taken by shooting operations. Even when cellular phone 1 is in the folded state, the user can check the taken image on the large screen of second display portion 20. Therefore, the user is not required to open or close cellular phone 1 for viewing the taken image, which improves the operability and convenience.
Camera portion 21 includes picture taking lenses, a picture taking element such as a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor, and RGB (i.e., red, green and blue) color filters. For the sake of simplicity, it is assumed that camera portion 21 in this embodiment has a CCD image sensor 29, which will be merely referred to as “CCD 29” hereinafter, as the image taking element. In camera portion 21, the light reflected by a subject passes through the picture taking lenses, and is converted by the color filters into RGB light rays, which enter CCD 29. As shown in
Owing to the above arrangement, camera portion 21 is located near hinge 4. When the user holds first body 2, the user supports a portion near camera portion 21 so that it is possible to reduce an influence, which may be caused by unstable holding with the user's hand during a shooting operation. Further, the antenna is removed from the rear surface of first body 2 so that second display portion 20 can have a large size. When shooting a subject, the user can easily check a self-portrait on a large screen while suppressing an influence by unstable holding.
Light portion 22 is used as an auxiliary light source for taking a picture by camera portion 21. In general, xenon lamps have been often used as auxiliary light sources. However, RGB LEDs (Light Emitting Diodes) are currently used in some cases. Cellular phone 1 may employ such LEDs, and the LEDs can be simultaneously turned on to provide white light illumination.
Second shutter button 23 is arranged at a center of the rear surface remote from first display portion 5 of first body 2, and is located under second display portion 20 when cellular phone 1 is in the folded state as shown in
In a conventional structure, a user must find a shutter button, which is hard to find due to its small size and its position, e.g., on a side surface of a first body. However, the embodiment does not require such a finding operation. Therefore, the operability and convenience are improved.
Second operation buttons 24a and 24b are arranged on the opposite sides of second shutter button 23 for setting or operating various kinds of data while checking information displayed on second display portion 20. By arranging second operation button group 24 in this position, the user can easily determine the positions of second operation buttons 24a and 24b on cellular phone 1 in the folded state, and can easily operate second operation buttons 24a and 24b.
Second shutter button 23 and second operation buttons 24a and 24b are utilized as operation buttons to be operated by the user for turning on/off various functions and determining decision and end of specific operations. In cellular phone 1 of an embodiment of the invention, these buttons can be utilized, e.g., for activating the light, turning on/off the light, selecting menu screens, turning on/off pictograph display, activating the camera, turning on/off key-lock, deciding selection, ending display, displaying mail body, selecting control items, playing and stopping MP3, and changing the light color.
Second operation buttons 24a and 24b can be utilized as control buttons, which are operated by the user to achieve changing (e.g., up/down and forward/backward) of control magnitudes of various functions. In cellular phone 1 of an embodiment of the invention, buttons 24a and 24b are utilized to perform, for example, selection and forward/backward changes on a menu screen, forward/backward change of various display images, up/down of light amount, forward/backward change of light color, forward/backward change of the incoming call record, incoming mail record and others, up/down of the TV channel, selection of backward/forward and next/previous in MP3 play, volume up/down, and zoom-in/out in zoom control. Second operation buttons 24a and 24b are control buttons, and primarily have functions as plus- and minus-buttons for various kinds of control magnitudes. In this embodiment, second shutter button 23 is not utilized as a control button. However, this is not restrictive, and second shutter button 23 may be utilized similarly.
As described above, the user can use second shutter button 23 and second operation buttons 24a and 24b without opening cellular phone 1, and thereby can perform the selection of a plurality of functions such as activation of the camera, turn-on of the light or change of pictograph display as well as the change of control magnitudes. Accordingly, it is not necessary to open cellular phone 1 for executing the functions, which can be changed on cellular phone 1 in the closed state, so that operability and convenience are improved.
Further, second display portion 20 can display images taken by camera portion 21. Therefore, the user can control shooting conditions and can process taken images by operating second shutter button 23 and second operation buttons 24a and 24b. Accordingly, the user can control the shooting conditions and can process the taken images on folded cellular phone 1 without opening it so that the operability and convenience are improved.
By employing the buttons serving as both the operation buttons and the control buttons, it is possible to reduce the sizes and the number of parts of cellular phone 1, and thereby can reduce the cost. The control button and the operation button are generally used as a “+” button (i.e., forward button) and a “−” button (backward button) in many cases, and can be operated in a similar manner so that the dual- or multi-purpose buttons are preferable. Thereby, the user can easily operate cellular phone 1 so that the operability and convenience are improved.
An antenna portion 25, an extendable helical portion 26, a battery portion 27 for carrying a battery and a second speaker 28 for sounding a ringer toner are arranged at the rear surface of second body 3 remote from input button group 7 and function button group 8.
Referring to
Since second display portion 20 is arranged between camera portion 21 and second shutter button 23 or second operation buttons 24a and 24b, camera portion 21 can be spaced by a constant distance from second shutter button 23 or second operation buttons 24a and 24b. Thereby, such a situation can be prevented that a user accidentally touches camera portion 21 or covers a sight of camera portion 21 with the user's finger when the user manipulates second shutter button 23 or second operation buttons 24a and 24b. Thus, it is possible to prevent such a situation that the user touches camera portion 21 with a finger to scratch parts such as a lens or to cause adhesion of dust. Consequently, the durability of the cellular phone can be improved, and the performance thereof can be maintained.
Further, cellular phone 1 is configured such that the user can hold folded cellular phone 1 with hinge 4 located in the upper position so that the user holding folded cellular phone 1 does not cover camera portion 21 with the user's hand. Therefore, the user can hold cellular phone 1 without giving attention to the position of camera portion 21.
Manners of taking a picture by cellular phone 1 according to the embodiment of the invention will now be described with reference to
In general, when a cellular phone displays an image on second display portion 20, it displays a mirror image, i.e., a laterally inverted image so that the user may not feel unnatural when viewing the image. In the invention, however, the manner is not restricted to this. According to the embodiment of the invention, the user can take a picture of the user himself/herself by cellular phone 1 in the folded state, which improves operability and usability. The state of cellular phone 1 for taking a picture of the user is not restricted to the folded state, and the user can take a picture by cellular phone 1 in the open state.
The buttons are arranged at the same surfaces of first body 2 and second body 3 of cellular phone 1 in the folded state. Therefore, when the user opens and operates cellular phone 1 after operating it in the folded state, and vice versa, the user can execute an entry operation via buttons immediately after opening or closing first body 2 while continuously holding second body 3. Thus, the user can smoothly operate cellular phone 1 without changing its position on the hand.
Description will now be given on antenna portion 25 of cellular phone 1 according to the embodiment of the invention.

By these setting, the user can select the light-emitting states of light portion 22 so that light portion 22 can be manually turned on/off, and can be always kept on similarly to a flashlamp. This improves the operability and convenience. By selecting the control manner between the short press and long press, multiple kinds of control can be achieved without increasing the number of operation buttons so that it is possible to suppress increase in cost due to increase in size and number of parts of the cellular phone.
When the user presses second shutter button 23 during the standby state, second display portion 20 displays, on its lower region, a left arrow, a selection item and a right arrow in this order. In this case, second operation button 24b can be used for successive selection. Each time second operation button 24b is pressed, second display portion 20 successively displays, in a region between the arrows, wallpaper setting, image checking, light amount, light color, incoming call, mail arrival, end of display and wallpaper setting in this order. The second operation button 24a is a backward selection button, and can be operated to change the selection items in the order of mail arrival, incoming call, light color, light amount, image checking, wallpaper setting, end of display and mail arrival in this order. When user presses second shutter button 23 functioning as the decision key in this situation after selecting the item with second operation button 24a or 24b, cellular phone 1 starts the operation for the item selected by the user.
The wallpaper setting mode is a mode for setting a standby screen displayed on second display portion 20. In this mode, setting can be performed to display selectively image files such as wallpaper images or taken images stored in third memory 52 of cellular phone 1, clock function, animation and JAVA® application. Each time the user presses second operation button 24a or 24b, the contents displayed on second display portion 20 change. By pressing second shutter button 23, the setting is completed, and the state of cellular phone 1 returns to the standby state.
The image checking mode is a mode for displaying and thereby checking the images, which are taken by camera portion 21 and are stored in third memory 52. Each time the user presses second operation button 24a (forward) or 24b (backward), second display portion 20 successively changes the taken images displayed thereon. For displaying only the taken images by discriminating them from other images, cellular phone 1 may be preset to store the taken images into a predetermined folder in the third memory, and the images stored in this folder may be successively displayed. Alternatively, flags may be assigned to files of images taken by camera portion 21 when storing such images, and only the image files thus flagged may be displayed.
The light amount mode is a mode for controlling the light amount of light portion 22. In the light amount mode, as shown in
By using buttons 23, 24a and 24b arranged on the rear surface of first body 2, the light amount of light portion 22 can be controlled, as will now be described in accordance with a flowchart of
When cellular phone 1 enters the light amount control mode, control portion 40 reads light amount data LX from third memory 52, and turns on the light with the light amount based on light amount data LC in step S10. When light portion 22 is already on, no change substantially occurs. Control portion 40 determines whether the user is pressing button 23, 24a or 24b arranged on the rear surface (step S11). When the button is being pressed, control portion 40 determines the button, which is being pressed by the user, and stores an identification number of the determined button in the memory (step S12). Then, a counter value I is set to zero for determining whether the user pressed the button for an ordinary time (short press) or a long time (long press) (step S13). After 10 milliseconds, counter value I is incremented by one (step S14). While the user is pressing the button, counter value I is incremented by one in response to every elapsing of 10 milliseconds (step S15). When the user releases the button (YES in step S15), processing corresponding to the pressed button starts (step S116).
When the user pressed the right button, control portion 40 determines the time (counter value I), for which the button was kept in the pressed position (step S17). When counter value I is larger than 100, control portion 40 determines that the long press was performed. In this case, no definition has been prepared for the long press of the right button so that the process moves through step S27 to step S21. When counter value I is equal to or lower than 100, control portion 40 determines whether light amount LX is smaller than a maximum value of 10 (step S18). When light amount LX is equal to or larger than 10 (NO in step S118), the light amount cannot be increased further so that the process moves through step S27 to step S21. If light amount LX is smaller than 10 (YES in step S18), control portion 40 increments the value of light amount LX by one (step S19), and turns on the light with light amount LX while displaying a bar of a length corresponding to the value of light amount LX on the second display portion (step S20).
When the user pressed the decision button, control portion 40 determines the time (counter value I), for which the button was kept in the pressed position (step S22). If counter value I is larger than 100, control portion 40 determines that the long press was performed. In this case, no definition has been prepared for the long press of the decision button so that the process moves through step S27 to step S21. When counter value I is equal to or lower than 100 NO in step S22), this means that the user ends the light amount control so that control portion 40 ends the light amount control mode to keep current light amount LX.
When the user pressed the left button, control portion 40 determines the time (counter value I), for which the button was in the pressed position (step S23). When counter value I is larger than 100 (YES in step S23), control portion 40 determines that the long press was performed. In this case, the long press of the left button means turn-off of the light so that light amount LX is set to zero (step S26). When counter value I is equal to or smaller than 100 (NO in step S23), control portion 40 determines whether light amount LX is lower than 1 or not (step S24). When light amount LX is zero, the light amount cannot be lowered further so that the process moves through step S27 to step S21. When light amount LX is equal to one or more (YES in step S24), control portion 40 decreases the value of light amount LX by one (step S25), and turns on the light with decreased light amount LX while displaying a bar of a length corresponding to the value of light amount LX on the second display portion (step S20).
When the process moves to step S21, the process further moves to step S28, and the process of controlling the light amount is performed again.
A light color mode is a mode for changing the light color of light portion 22. Light portion 22 includes red LED 22R, green LED 22G and blue LED 22B. Therefore, these LEDs can be selectively combined to emit the light in red, green, blue, yellow, purple or light blue in addition to the white light. Each time the user presses second operation button 24a (forward) or 24b (backward), light portion 22 changes the color of light emitted therefrom. When the user pressed the left button (second operation button 24b) for one or more seconds, and thus performed the long press, light portion 22 stops the light emission. As described above, by manipulating second operation button 24a or 24b, the user can change the light color of light portion 22 without opening cellular phone 1 in the folded state so that the operability and convenience are improved.
An incoming call record mode is a mode of displaying a record of incoming calls. Since third memory 52 has stored the record of incoming calls, it is possible to display the time and caller after cellular phone 1 received an incoming call. Second display portion 20 displays the incoming call times and the telephone numbers or names of callers, and second display portion 20 changes contents of the incoming call record each time the user presses second operation button 24a (newer call) or 24b (older call). In this manner, the user can manipulate second operation button 24a or 24b to select the incoming call record displayed on second display portion 20 without opening cellular phone 1 in the folded state. Therefore, the operability and convenience are improved.
A mail display mode is a mode for browsing a mail received by cellular phone 1. Second display portion 20 displays its title and sender. When the user presses second shutter button 23, second display portion 20 displays a body of the mail. Each time the user presses second operation button 24a (next mail) or 24b (previous mail), second display portion 20 changes the reception record. The mail display mode ends when the user presses second shutter button 23 for a long time. As described above, the user can select the received mail, of which contents are displayed on second display portion 20, by pressing second operation button 24a or 24b without opening cellular phone 1 in the folded state so that the operability and convenience are improved.
With buttons 23, 24a and 24b arranged on the rear surface of first body 2, the user can display contents of the mail on second display portion 20 in the following manner, which will now be described with reference to a flowchart of
When cellular phone 1 entered the mail content display mode, control portion 40 reads the mail at the first position in third memory 52, and displays the sender and title of the first mail on second display portion 20. In a mail box of the memory, values MX representing mail numbers starting from the mail at the first position are allocated to the mails, respectively. In this case, mail number MX is set to “1” (step S30). Then, control portion 40 determines whether the user pressed button 23, 24a or 24b arranged on the rear surface or not (step S31). When the button was pressed, control portion 40 determines or specifies the button pressed by the user, and stores identification information of the button thus determined in the memory (step S32). Then, counter value I is set to zero for determining whether the user pressed the button for a normal time (i.e., short press) or for a long time longer than the normal time (step S33). After 10 seconds, counter value I is incremented by one (step S34). While the user is pressing the button, counter value I increases by one in response to every elapsing of 10 milliseconds. When the user stops pressing of the button, a process corresponding to the pressed button starts (step S36).
When the user pressed the right button, control portion 40 determines the time (counter value I), for which the button was pressed (step S37). If the value I is larger than 100, control portion 40 determines that the long press was performed. In this case, no definition has been prepared for the long press of the right button so that the process moves through step S47 to step S41. When counter value I is equal to or lower than 100, control portion 40 determines whether mail number MX is smaller than the maximum number of stored mails (step S38). When mail number MX is equal to or larger than the maximum number of stored mails, there is no next mail so that the process moves through step S47 to step S41. When mail number MX is smaller than the maximum number of stored mails, control portion 40 increments mail number MX by one (step S39), and control portion 40 writes data for display in the display memory so that second display portion 20 may display the sender and tile of the mail bearing mail number MX (step S40).
When the user pressed the decision button, control portion 40 determines the time (counter value I), for which the button was pressed (step S42). When value I is larger than 100, control portion 40 determines that the long press was performed. In this case, the long press of the decision button means that the user intends to end the mail display. Therefore, control portion 40 ends the mail display mode. When the value I is equal to or lower than 100, control portion 40 displays the body of the mail bearing mail number MX on second display portion 20 (step S43), and the process moves through step S47 to step S41.
When the user pressed the left button, control portion 40 determines the time (counter value I), for which the button was pressed (step S44). When counter value I is larger than 100, control portion 40 determines that the long press was performed. In this case, no definition has been prepared for the long press of the left button so that the process moves through step S47 to step S41. When the value I is equal to or lower than 100, control portion 40 determines whether mail number MX is larger than one or not (step S45). When mail number MX is equal to or lower than one, the mail bearing this number is the first mail so that the process moves through step S47 to step S41. When mail number MX is larger than one, control portion 40 decrements the value of mail number MX by one (step S46). For displaying the sender and title of the mail of mail number MX on second display portion 20, control portion 40 writes data for such display in the display memory (step S40). The process moves to step S41, and further moves to step S48 so that control portion 40 repeats the processes for displaying the mail.
As described above, the user can use three buttons for cellular phone 1 to perform the operations for forward/backward display of the senders and titles of the mails, display of mail body and ending of the mail display mode.
Cellular phone 1 enters the incoming call record mode or the mail display mode when the corresponding selection item is selected during the standby state. In addition to this selecting operation, the user can selectively achieve such modes by pressing second shutter button 23 when receiving a call or a mail. Second display portion 20 performs specific display for a predetermined time after receiving a call or a mail. If the user presses second shutter button 23 when this specific display is performed, cellular phone 1 can enter the incoming call record mode or the mail display mode without displaying the foregoing selection items.
Since cellular phone 1 provided with television tuner 59, second display portion 20 can display television images. When the television images are displayed, the user can operate second operation buttons 24a and 24b to select the channel or to control the sound volume. The user can select the intended operation from the channel selection and the volume control by pressing shutter button 23. As described above, when the user watches the television on second display portion 20, the user can change the channel without opening cellular phone 1 for operating numeric buttons or the like, but can change the channel by manipulating second operation buttons 24a and 24b while keeping cellular phone 1 in the folded state so that the operability and convenience are improved. Further, when listening to a sound of the television program with cellular phone 1, the user can change the volume without opening cellular phone 1 for operating numeric buttons or the like, and can change the sound volume by manipulating second operation buttons 24a and 24b while keeping cellular phone 1 in the folded state so that the operability and convenience are improved.
The user can manipulate shutter button 23 and second operation buttons 24a and 24b to reproduce the MP3 data stored in the third memory of cellular phone 1. As described above, when the user listens to the audio data with cellular phone 1, the user can change the tune or song to be reproduced without opening cellular phone 1 for operating numeric buttons or the like, and can change it by operating second operation buttons 24a and 24b so that the operability and convenience are improved.
Description will now be given on the operation of second shutter button 23 and second operation buttons 24a and 24b in the camera mode. When the user performs the long press of second shutter button 23 during standby, camera portion 21 is activated, and cellular phone 1 enters the camera mode. When the user presses second shutter button 23 in the camera mode, the shutter operates.
When the user presses second operation button 24b, light portion 22 changes the light color in the order of white, red, green, blue, yellow, purple, light blue and white in response to every button pressing, and keeps the on state only while second operation button 24b is being pressed. When second operation button 24b is continuously pressed for one or more seconds, light portion 22 changes to the continuous on state. When second operation button 24b is pressed for one or more seconds in the continuous-on state, light portion 22 is turned off. As described above, depending on the short press or the long press of second operation button 24b, it is possible to select the light color of light portion 22 as well as the on/off states of light portion 22 so that the operability and convenience are improved. By changing the control in accordance with the short press and the long press, it becomes possible to perform multiple kinds of control without increasing the number of operation buttons, and it is possible to suppress increase in cost, which may be caused due to increase in size and number of parts of cellular phone 1.
When the user presses second operation button 24a, setting can be performed in the camera mode. In the example illustrated in
The zoom control mode is a mode for controlling the zooming in the shooting operation. Similarly to the light amount mode already described, second display portion 20 displays, at its lowermost region, left and right arrows as well as an indicator, which extends horizontally on the screen for indicating the current zooming state. Each time the user presses second operation button 24a (zoom-in) or 24b (zoom-out), the indicator increases or decreases in length, and at the same time, the zooming state is controlling. When second shutter button 23 is pressed after the zooming control, the control mode ends, it becomes possible to operate the shutter by pressing second shutter button 23.
The brightness control mode is a mode for controlling the brightness of the taken image. Similarly to the light amount mode already described, second display portion 20 displays, at its lowermost region, left and right arrows as well as an indicator, which extends horizontally on the screen for indicating the current brightness. Each time the user presses second operation button 24a (bright) or 24b (dark), the indicator decreases or increases in length, and at the same time, control portion 40 controls the brightness of the displayed image.
In the above example, the brightness is controlled before the shutter operation. However, the timing of the brightness control is not restricted to this. For example, the second display portion may display a user checking screen, on which the user can determine whether the brightness control is to be effected on the image already taken or not before storing the image. When the user requests the brightness control, the cellular phone enters the brightness control mode. In this case, the image of which brightness is controlled by the user can be stored in third memory 52. If the image control is allowed before storing the taken image, control of tones and touches of images as well as application of image ornaments such as a frame can be effected by using second shutter button 23 and second operation buttons 24a and 24b, in addition to the brightness control of the taken images. As described above, the uses takes image, and processes the taken image while viewing it on second display portion 20 before saving the image, whereby the user can store the image, which is already subjected to the image control or processing. Accordingly, when the user intends to control and/or process the taken image immediately after the shooting, it is not necessary to read the image, which is already stored, and to effect the image control/processing on the image thus read so that the operability and convenience are improved.
The light amount mode is a mode for controlling the amount of light emitted from light portion 22. Second display portion 20 displays, at its lowermost region, left and right arrows as well as an indicator, which extends horizontally on the screen for indicating the current light amount. Each time the user presses second operation button 24a (bright) or 24b (dark), the indicator decreases or increases in length, and at the same time, the light amount of light portion 22 changes.
The light color mode is a mode for changing the light color of light portion 22. Since light portion 22 has red LED 22R, green LED 22G and blue LED 22B, these LEDs can be combined to emit the light, e.g., in red, green, blue, yellow, purple and light blue in addition to white. Each time the user presses second operation button 24a (forward) or 24b (backward), light portion 22 changes the color of light.
Another embodiment of the invention is shown in
Cellular phone 70 has two modes, i.e., an ordinary mode and a camera mode. After the power-on, cellular phone 70 is in the ordinary mode. For taking pictures by the camera, the user must change cellular phone 70 to the camera mode for activating the camera function and using the display portion as a finder.
According to multi-button 72, the user can press up button 72b and down button 72c for selecting various control items, and can press left button 72e and right button 72d for changing control magnitudes in the setting modes selected with up button 72b and down button 72c. For example, when the user presses down button 72c one time during standby in the ordinary mode, light on/off setting is selected. When down button 72c is subsequently pressed two times, the image checking mode is selected. When right button 72d is pressed in the image checking mode, second display portion 20 successively displays images, which were taken by camera portion 21 and are already stored in third memory 52. Conversely, by pressing left button 72e, second display portion 20 successively and reversely displays the images.
Without opening cellular phone 70, as described above, the user can select the control items such as light on/off and image checking mode by operating up button 72b and down button 72c, and can change the control magnitude by operating right button 72d and left button 72e. Selection of the control items is independent of selection of the control magnitudes. This facilities the operation by the user. Also, selection of the control items and selection of the control magnitudes can be performed while keeping the close state, and it is not necessary to open the cellular phone for such selection and change so that the operability and convenience are improved. Further, second display portion 20 displays images taken by camera portion 21. Therefore, the user can perform selection of various control items, change of control magnitudes and processing for the images taken by camera portion 21 while keeping cellular phone 70 in the folded state. Consequently, the operability and convenience are improved.
In this embodiment described above, up button 72b and down button 72c are buttons for changing the control items. This is not restrictive. For example, all buttons 72a-72e of multi-button 72 may have functions as decision buttons for on/off selection of pictograph display, key-lock, light on/off and others.
Cellular phone 70 can enter the mail display mode immediately after cellular phone 70 receives a mail, or when the user performs a specific operation (i.e., double-click of decision button 72a). When the user presses decision button 72a in the mail display mode, second display portion 20 displays a body of the latest mail. If the body of mail is too long to display it fully on second display portion 20, display portion 20 displays only a part of the body. The user can presses down button 72c to scroll the body up on the screen of second display portion 20 so that a subsequent portion of the mail can be displayed. Also, the user can presses up button 72b to scroll the mail down on the screen of second display portion 20 for displaying a beginning portion of the mail. The user can press left button 72e to display an older mail immediately preceding the mail, which is currently displayed. The user can press right button 72d to display on second display portion 20 a newer mail immediately following the mail, which is currently displayed. When the user intends to end the mail display mode, the user can double-click decision button 72a so that cellular phone 70 returns to the standby mode, and second display portion 20 displays the standby screen. As described above, even when cellular phone 70 is in the folded state, the user can operate cellular phone 70 to display the mail on second display portion 20, to scroll the mail and to display another mail. Thereby, when the user intends to read the mail body, the user is not required to open cellular phone 70 in the closed state for reading the mail on first display portion 5 and for selecting the intended mail with numeric buttons or the like. While keeping cellular phone 70 in the folded state, the user can change the mail to be displayed by operating right button 72d and left button 72e, and can scroll the displayed mail by operating up button 72b and down button 72c. Thereby, the operability and convenience are improved.
When the user performs a specific operation, cellular phone 70 enters the TV mode. According to the allocation of functions to multi-button 72 illustrated in
When the user performs a specific operation, cellular phone 70 enters the MP3 play mode. According to the allocation of functions to multi-button 72 illustrated in
As described above, since cellular phone (70) is provided with the plurality of operation portions functioning as the decision buttons or directional buttons, various kinds of control, setting and change can be performed even when cellular phone (70) is in the folded state, and the operation of opening cellular phone (70) is not required. Further, cellular phone (70) can be used for various purposes while keeping it compact, i.e., in the folded state so that the convenience is improved. Since an arrangement of buttons is devised, the operability of the user is improved.
