  • Patent number: 8284294
    Abstract: A compound-eye image pickup apparatus includes: a plurality of image pickup devices each including a focusing lens; a moving device configured to move the focusing lens; an automatic focusing device configured to cause the moving device to move the focusing lens within a predetermined range, to acquire focusing positions of each of the plurality of image pickup devices; and a detecting device configured to detect whether or not the focusing position can be acquired, wherein when the detecting device detects that the focusing position of at least one of the plurality of image pickup devices is acquired and the focusing position of the remaining image pickup device is not acquired, the automatic focusing device moves the focusing lens of the image pickup device for which it is detected that the focusing position thereof is not acquired, within an additional range outside of the predetermined range to acquire the focusing position thereof.

  • Patent number: 8149317
    Abstract: A feature area having a visual feature is analyzed for each of at least three of similar images in a memory card, and the analyzed feature areas are displayed on a display screen while overlapped with a reference image. The visual feature is used to distinguish an image from other images in the plural images. In the case where the images of the feature areas are displayed on the display screen while visually overlapped, when a user touches a touch panel on the display screen, the image corresponding to the feature area to which the touched point belongs is read from the memory card and displayed on the display screen.

  • Patent number: 8018498
    Abstract: A digital still camera includes a lens system and an image sensor. The image sensor receives object light through the lens system to output an image signal of an object, wherein exposure control and autofocus control of the lens system are carried out according to the image signal. The image sensor photographs an image of the object after the exposure control and the autofocus control. Auxiliary light is applied to the object with an illumination light source for the autofocus control. A second exposure value is determined by use of a first exposure value determined according to object brightness measured while the illumination light source is inactive. Exposure is carried out to measure object brightness by use of the second exposure value while the auxiliary light is applied, for determining a third exposure value for use in the autofocus control with the auxiliary light.
