ABSTRACT:
A natural white balance is achieved in images that are captured while emitting a flash. The white balance of an image is adjusted using a WB adjustment portion and a mixture ratio calculation portion estimating a mixture ratio of an external light component and a flashed light component that are present in an image captured with emitting a flash, from the image obtained that is captured while emitting a flash and an image signal that is obtained without emitting a flash. Further, an external light WB coefficient determination portion determines an WB coefficient for the external light, a flashed light WB coefficient setting portion sets a WB coefficient for the flashed light, and a WB processing portion continuously performs WB processing on the image captured while emitting a flash by using the mixture ratio as an interpolation ratio.
