    Abstract: The sizes of images obtained by electronic zoom processing are rendered constant to a certain degree. To accomplish this, an image within a zoom area is enlarged or reduced to the size of a super-extended graphics array (SXGA), and the resulting image data is recorded on a memory card, if the zoom area has a size near that of the SXGA. The image within the zoom area is recorded on the memory card upon being enlarged or reduced to the size of a super VGA (SVGA) if the zoom area has a size near that of the SVGA. The image within the zoom area is recorded on the memory card upon being enlarged or reduced to the size of a VGA if the zoom area has a size near that of the VGA. Thus, when Images represented by image data recorded on the memory card are zoomed, the sizes of the zoomed images are limited.

    Abstract: In an CCD image sensor, when an image of a partial area is used, a frame rate is enhanced. Horizontal transfer of signal charges of an i-th line read out to a horizontal transfer portion is stopped at the time point when all or a part of a tail portion 74 subsequent to an extraction target portion 72. Under this state, the signal charges of an (i+1)-th line are transferred to the horizontal transfer portion. Thereafter, the horizontal transfer is started. Through this operation, unnecessary signal charges of the tail portion 74 of the i-th line and unnecessary signal charges of a head portion 82 of an (i+1)-th line are combined. By partially overlapping adjacent lines with each other, the cycle number of horizontal transfer clocks required for the horizontal transfer per line can be reduced as compared with a normal operation, thereby enhancing a frame rate.

  • Patent number: 7265783
    Abstract: A system controller controls a solid-state image pickup device so as to read pixels at a predetermined pixel skip-reading-out rate. During pixel skip-reading-out, the system controller adds up, for example, four pixels to acquire a value representative of a unit area for pixel skip-reading-out. A space between adjoining ones of pixels to be added up is set to, for example, a half of an inter-sample space, whereby an MTF of an image signal representing added pixels, which is attained at the sample rate, is set to 0. Consequently, an aliasing noise can be eliminated and deterioration in image quality can be prevented. Moreover, since four pixels are added up irrespective of a pixel skip-reading-out rate, a sensitivity will not vary.

  • Patent number: 7057658
    Abstract: In a digital camera, when a motion image reducing mode is set, a pointer is displayed on a monitor. When the operator operates on cursor key, the pointer moves, and when the operator operates a determination key at two different pointer positions, a rectangular frame is formed. Namely, the two pointer positions represent upper left and lower right coordinates of the frame. The picked up real time motion image is displayed in the rectangular frame. The displayed motion image is reduced to a magnification corresponding to the ratio of the rectangular frame with respect to the monitor frame. When the operator operates a shutter button at this time, the image in the motion image frame is recorded on a memory card.

  • Patent number: 7012641
    Abstract: The zoom speed of a zoom function is detected by a zoom lever detection circuit. A sensed image is displayed on a monitor, and a desired partial region in that sensed image is designated using a region designation lever. A compression circuit compresses the designated region and a non-designated region using different characteristics. A region detector controls the designated region on the basis of the detected zoom speed. In another arrangement, enlargement/reduction zoom operation by a zoom function is executed by a zoom lever. A sensed image is displayed on a monitor, and a desired partial region in that sensed image is designated using a region designation lever. A compression circuit compresses the designated region and a non-designated region using different characteristics. A region detector controls the designated region on the basis of the zoom operation.

  • Patent number: 6947082
    Abstract: A system controller controls a solid-state image sensor, and performs read-out at a predetermined subsampling ratio. In the event that the size of the image-taking area and the subsampling ratio do not agree, the system controller executes image size conversion processing with a digital processing unit, and converts the image size to an image size corresponding to a request from a peripheral device unit. Also, the system controller performs changing of the image-taking area following ending of the reading out from the solid-state image sensor, thereby obtaining normal frame signals. Accordingly, even in the event that zooming is performed by changing the subsampling ratio, zooming operations can be performed with an arbitrary zooming ratio, and reading out of the image-taking information is made to be suitable.

  • Patent number: 6943835
    Abstract: An image pickup apparatus is disclosed to prevent recording of a degraded image by restricting setting of an electronic zoom function when a recording mode is set to a low-compression ratio mode or non-compression mode. The image pickup apparatus comprises a processing device for electronically enlarging an image picked up by an image pickup unit, a setting device for setting compressing operation for the image picked up by the image pickup unit, and a control device to restrict operation of the processing device in accordance with the compressing operation for the image which is set by the setting device. When a compression ratio equal to or less than a predetermined value is set by the recording mode setting unit or the non-compression mode is set, a system control circuit inhibits the electronic zoom function that tends to cause a deterioration in image quality from being turned on.

  • Patent number: 6906746
    Abstract: When a subject is imaged for the purpose of deciding the angle of view, the full image that is capable of being sensed by a CCD is displayed on an LCD. The user designates the position of a cropping area in the image being displayed. Only image data representing the image within the border of the designated area is recorded on a memory card. Since the amount of image data to be recorded on the memory card is thus reduced, image data representing images of a greater number of frames can be recorded on the memory card.

  • Patent number: 6853401
    Abstract: On a screen G1 of a liquid crystal display, a digital camera displays an AF cursor for use as a focusing point. Thus, a shooter shifts the AF cursor to the portion of a subject to be focused, so as to carry out the setting. Here, when the subject is zoomed up to an enlarged screen G2 through an optical zooming operation, the AF cursor is displayed on the enlarged screen G2, following the subject. Moreover, in the case when the subject is electronically zoomed up to an enlarged screen G3, the AF cursor is also displayed on the enlarged screen G3, following the subject. Thus, even when a zooming process is carried out, it is not necessary to adjust the position of the AF cursor; thus, it becomes possible to improve the operability of the digital camera.

    Abstract: A drive recorder attains scenic images surrounding a vehicle or images inside a vehicle chamber in a specific direction, as being useful for verifying a cause of an accident. As an impact sensor detects an occurrence of an accident, a control unit displays an image by an on-vehicle camera on a screen of a display. Accordingly, a user is able to quickly record target objects that supposedly help to verify the cause of the accident, such as the vehicle running into from behind and running away, a traffic light, a traffic marking and so forth, by simply turning a photographic direction of the on-vehicle camera toward the target objects, with a simple operation on a touch panel, even in an emergency.
