Abstract: At the start of driving a stepping motor, a CPU sets the switching widths of the first through eighth states in a pulse width setting register, sets the switching counts of the first through eighth states in a pulse switching count register, and sets the start of driving the stepping motor in a driving start register. A latch then outputs an excitation pulse, and the stepping motor is accelerated, driven at a constant speed, decelerated, and stopped. By setting the switching widths and switching counts of the first through eighth states at the start of driving and setting the start of driving, the CPU need not control the stepping motor, reducing the process burden on the CPU.

Abstract: A computer obtains a change amount of an image of a manuscript. If the change amount of the image of the manuscript is equal to or larger than a predetermined threshold, the computer determines that the image does not have movement, such as in a case where the manuscript is replaced, and switches the resolution of the image, which is possible to shorten the processing time, to low resolution. In a case where the manuscript is placed on a base, if the change amount of the image of the manuscript is less than the predetermined threshold, and the computer determines that the image does not have movement, the computer switches the resolution of the image to high resolution.

Abstract: An electronic still camera has first and second gain controller circuits and a gain storage memory. The gain storage memory includes a first gain table for storing gains for an R amplifier and a B amplifier of the first gain controller circuit; and a second gain table for storing gains for an R amplifier and a B amplifier of the second gain controller circuit, during auto white balance control using light emission of a strobe.

Abstract: A CPU displays an image on a display device with reference to an image location table stored in advance in a RAM. When coordinates on the image are sequentially designated by an input device, the CPU sequentially compares the locations specified by the designated coordinates with those of checking points stored in the image location table. The CPU determines that the operator is authorized when errors or differences between the locations compared with each other are within an allowable range and when the order of designation of the coordinates is appropriate.

Abstract: A controller creates a file of image data picked up, downloaded by a communication function, or annexed to a received mail and stores it in a RAM. When an album mode is selected, the controller creates a thumbnail(s) of the image(s) file stored in the RAM and stores them on an album management table. The controller then develops the thumbnails in a display buffer according to the content of the album management table. When the controller receives an image of an image file with copyright protection information, it creates thumbnail data from the image of the received image file. Then, the controller also develops this thumbnail data in the display buffer. The controller then simultaneously displays the thumbnails developed in the display buffer on a main display unit such that sources of the thumbnails can be recognized at a glance. When the album mode ends, the display buffer is then cleared.

Abstract: When a searching of an image file is indicated, a wireless telephone extracts image files and makes the image files to be icons, and displays the icons in a layout on a display unit. When a positional information acquiring indication is detected, the wireless telephone acquires self-positional information, centering on the acquired self-position, leaves only the image files to which the positional information are added, reads place name folders corresponding to the image files, and displays those in a layout. When one of the displayed icons is selected and a network connection indication is detected, the wireless telephone achieves a session with a map information service company, and transmits the self-positional information and the positional information which the selected image file includes, to the map information service company.

Abstract: In a photosensor system formed of a photosensor array including a plurality of photosensors arranged in a two dimensional direction, the intervals of the reset pulse, read pulse and pre-charge pulse applied to each row of the photosensor array are respectively set equal to the sum of the reset period, the read period, and the pre-charge period. It follows that even where the read processing time of a single screen is shortened by allowing the processing cycles for the rows to partially overlap with each other, the reset period, the pre-charge period and the read period are prevented from being overlapped in time with each other, making it possible to perform the read operation accurately.

Abstract: A transformation coefficient storing unit has correction tables which are generated based on classification of zooming magnification in a manner of arithmetic progression. An optical mechanism unit supplies information on a zooming magnification Z to a switch control unit of the transformation coefficient storing unit. The switch control unit controls a table selection unit to select any from the correction tables based on the zooming magnification Z. The transformation coefficient storing unit selects a coefficient set from the selected correction table based on inclination angles ?H and ?V and supplies the selected coefficient set to a trapezoidal correction unit. The trapezoidal correction unit performs trapezoidal correction based on the supplied coefficient set.

Abstract: Each of a horizontal chart generating unit and a vertical chart generating unit generate eight charts #0 to #7, the bright/dark sections being placed sequentially in equal distances. Each pattern of each charts #0 to #7, is shifted little by little. Each chart #0 to #7 is sequentially projected on a screen, and each of the sensor controllers obtains an average phase difference, by obtaining the sensor data obtained by the result of measuring, from the distance-measuring sensors, and obtains the angle between an ideal screen that is vertical to a center line of distance-measuring sensors and the screen, by obtaining the distance to the two distance-measuring points on the screen, based on the obtained average phase difference. A projector control unit replaces the angles that each of the sensor controllers obtains, to inclination angles ?H and ?V of the screen, and supplies the angles to a trapezoidal correction unit.

Abstract: A trapezoidal correction unit included in a projector positions a quadrangle p?q?r?s? after correction within a quadrangle pqrs before correction, by using inclination angles v and h. In this case, the trapezoidal correction unit performs correction in a manner that the quadrangle p?q?r?s? establishes symmetry with respect to a vertical line including a light axis point k which is an intersection of a light axis and a screen, and a part or the all of the bottom side of the quadrangle p?q?r?s? contacts or is positioned near a part or the all of the bottom side of the quadrangle pqrs. The trapezoidal correction unit sets the size of the quadrangle p?q?r?s? in a manner that the area of the quadrangle p?q?r?s? becomes the largest. The trapezoidal correction unit projectively transforms the quadrangle pqrs before correction represented by an input image signal into the quadrangle p?q?r?s? after correction temporally continuously.

When a camera mode startup power on/off key (manner key in the phone mode) provided on the side of the body is pressed in the power-off state, the power control unit applies power from a power supply to each circuit except the radio communication unit, whereby the signal-off mode is set and an imaging device, DSP and subdisplay unit are activated. After that, when a shutter key (memo key in the phone mode) is pressed, an image at that time is captured and stored into a RAM.
