    摘要: An image-capturing EV is obtained when a shutter button is half pressed, and whether to flash an electronic flash for a subject of low luminance is determined according to the image-capturing EV. If it is determined that the electronic flash should be flashed for the subject of low luminance, a white balance is adjusted according to an electronic flash light. If it is determined that the electronic flash should not be flashed for the subject of low luminance, color information relating to a plurality of areas divided from an entire image plane is acquired, and the number of areas belonging to a shade determination frame, which indicates a color distribution range corresponding to the shade, is found according to the acquired color information. Then, whether a type of the light source is the shade or the daylight is determined according to the obtained image-capturing EV and the number of areas belonging to the shade determination frame. The white balance is adjusted according to the determined type of the light source.

    摘要: A digital camera has a feature to photograph a subject and record the image data onto a recording medium in a dynamic range wider than that required for printing, the digital camera further having a feature to store tag information into an image file, together with the image data, and record the image file onto the recording medium, the tag information including: range compression information indicating whether dynamic range compression has been made; maximum range information indicating the maximum subject reflection factor before and after the dynamic range compression; and knee point information indicating the subject reflection factor assumed when the dynamic range compression was made.

    摘要: An image combined high sensitivity image and low sensitivity image is provided with well-adjusted white balance and broad dynamic range. The image is obtained by multiplying the combined data by total gain that depends on scene. A white balance is adjusted with gain value calculated from of high output image data. Lv value representing luminance is calculated and compared with a threshold to decide whether or not the high sensitivity image and the low sensitivity image should be combined. First gamma correction unit performs gamma-correction for the image signal derived from the high sensitivity signal with first gamma character, second gamma correction unit performs gamma-correction for the image signal derived from the low sensitivity signal with second gamma character that is different from the first gamma character, and addition unit combines the image signal from the first gamma correction unit and the image signal from the second gamma correction unit.

    摘要: According to the present invention, when a lens is moved in an operation of an operation device, the focal information calculated for each travel position of the lens can be graphed corresponding to the lens position, and the focal information about the current lens position can be identified from the focal information about another position. Thus, a manual focus adjustment can be made while checking the graph. Especially, since the history of the focal information calculated for each lens travel position can be graphed, the lens can travel to the lens position in which a desired peak can be obtained when there are a plurality of peaks of focal information on the graph.
