摘要：
A natural white balance is achieved in images that are captured while emitting a flash. A WB adjustment portion is provided with a mixture ratio calculation portion that estimates a mixture ratio of an external light component and a flashed light component that are present in an image that is 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, an external light WB coefficient determination portion that determines an WB coefficient for the external light, a flashed light WB coefficient setting portion that sets a WB coefficient for the flashed light, and a WB processing portion that continuously performs WB processing on the image captured while emitting a flash by using the mixture ratio as an interpolation ratio.
