Patent ID: 7688358

Claim:
An image-capturing apparatus comprising: a solid-state imaging sensor which outputs a signal corresponding to a quantity of incident light; a white balance gain calculator for calculating white balance gains of an image from color differences of pixels whose luminance is equal to or greater than a reference luminance, in preference to color differences of pixels whose luminance is less than the reference luminance, among all pixels forming the image originating from the output signal; a white balance adjuster for adjusting white balance of the image in accordance with the calculated gains of white balance; and a gain correction instructing unit which performs a pixel determination as to whether or not a ratio of dark pixels, among all pixels of the image, whose luminance is lower than the reference luminance and whose color differences fall within a predetermined correction target area in a color-difference space, is greater than or equal to a reference ratio, and instructs the white balance gain calculator to make a correction to the white balance gains in accordance with a predetermined correction coefficient when the ratio of dark pixels is equal to or greater than the reference ratio.
