Patent ID: 7808545

Claim:
An image-pickup system for producing images by imaging an object, the system comprising: a mode switching unit that switches a mode at least between an imaging mode that captures an image of an object and an adjustment mode; an input unit which inputs images of a color chart composed of at least three colors including an achromatic color and a chromatic color by imaging a single object; a color adjustment unit which sequentially executes both a white balance adjustment by color-measuring an achromatic color portion of the color chart on the single object and a color balance adjustment by color-measuring a chromatic color portion of the color chart on the single object in a case that the mode is switched to the adjustment mode by the mode switching unit; a photometric region selecting unit that selects automatically, in the adjustment mode, a partial photometric region corresponding to each of the colors of the color chart, and selects, in the imaging mode, a partial photometric region that is different from the partial photometric region selected in the adjustment mode; and an exposure control unit which, in the adjustment mode, controls exposure of light incident from the object using photometric information obtained by making photometric measurement in an image signal included in the images on a partial photometric region corresponding to each of the colors selected by the photometric region selecting unit.
