Abstract
An image processing circuit includes a gain calculation circuit and a digital amplifier. The gain calculation circuit calculates a first gain with which an average color-difference value in a whole region of a pickup image is brought close to a predetermined convergent point. The digital amplifier performs correction of a white balance of a pixel of the pickup image with a candidate pixel that is of a first candidate pixel calculated based on the first gain and a second candidate pixel calculated based on a second gain associated with each of divided regions and in which a color-difference component is closer to the predetermined convergent point.
