PROBLEM TO BE SOLVED: To achieve a natural white balance in images that are captured by emitting a flash. SOLUTION: A WB adjustment portion 312 is provided with a mixture ratio calculation portion 3121 that estimates a mixture ratio W of an external light component and a flashed light component that are present in an image that is captured without emitting a flash from an image obtained that is captured by emitting a flash and an image that is obtained without emitting a flash, an external light WB coefficient determination portion 3123 that determines a WB coefficient WBcoe1 for external light, a flashed light WB coefficient setting portion 3124 that sets a WB coefficient WBcoe2 for flashed light, and a WB processing portion 3120 that continuously performs WB intermediate adjustment between the WB coefficient WBcoe1 for the external light and the WB coefficient WBcoe2 for the flashed light on the image captured by emitting a flash by using the mixture ratio W as an interpolation ratio.
