Patent ID: 7830419

Claim:
A digital camera for subjecting a main image, which is a user's intended captured image, to white balance processing, the camera comprising: first image acquisition means for acquiring a first image data by means of capturing a subject image identical with that of the main image, without firing a strobe light for preliminary illumination; second image acquisition means for acquiring a second image data by means of capturing a subject image identical with that of the main image while firing a strobe light for preliminary illumination; data acquisition means which divides each of the first and second image data into a plurality of blocks and acquires, as block information, a typical color value of each of the blocks and the type of a light source of each of the blocks, and acquires a tendency of a color change on the basis of a comparison between the acquired block information about the first image data and the acquired block information about the second image data; environment light source estimation means for estimating an environment light source of the subject on the basis of at least the acquired tendency of a color change; and gain-computing means for computing a white balance gain of the main image in accordance with the estimated environment light source.
