PROBLEM TO BE SOLVED: To provide an image processing apparatus which can detect the brightness of a subject well, even if the aperture of a lens at the imaging time cannot be acquired from an interchangeable lens, and performs highly accurate white balance correction according to the brightness of the subject, and to provide an imaging device, an image processing method and an image processing program.SOLUTION: The brightness of a subject is detected based on an image captured by an imaging device, the aperture at the time of imaging and the shutter speed, and white balance of the captured image is corrected based on the brightness of the subject thus detected. When the aperture of a lens at the time of imaging cannot be acquired from an interchangeable lens, the aperture at the time of imaging is estimated by an aperture estimation unit. The aperture estimation unit estimates the aperture at the time of imaging based on the shutter speeds when imaging a flash emission image and a flash non-emission image, the subject distance, the guide number of flash light when imaging the flash emission image, and the amount of reached flash light.SELECTED DRAWING: Figure 8 |
