Abstract
An image processing unit (31) according to a preferred aspect of the invention includes an image acquisition unit (41) that acquires a first image signal indicating a first flash emission image which is captured by a main imaging operation while flash light is emitted and a second image signal indicating a second flash emission image which is obtained by capturing the same scene as that of the first flash emission image with an exposure time different from an exposure time of the first flash emission image, using a reference imaging operation, while the flash light is emitted, a ratio calculation unit (43) that calculates a ratio of the first image signal to the second image signal in each region, and a determination unit (45) that determines a main object region and a background region on the basis of a threshold value.
