Claim:
1. An image processing device comprising: an acquisition unit that acquires a captured image including a first image based on a first image signal, which is obtained from an object image that passes through a pair of regions of an imaging lens, is pupil-divided, and is formed, and a second image based on a second image signal corresponding to an image signal, which is obtained from an object image that passes through the imaging lens, without being pupil-divided, and is formed, the first image signal and the second image signal being output from an imaging element including a phase difference pixel group that outputs the first image signal; a correction unit that calculates a shading characteristic correction coefficient on the basis of a first comparison result between the first image and the second image included in an early-acquired image which is acquired first of a pair of captured images acquired at different times by the acquisition unit and a second comparison result between the first image and the second image included in a late-acquired image which is acquired later than the early-acquired image of the pair of captured images, and corrects shading characteristics of the late-acquired image on the basis of the calculated shading characteristic correction coefficient; a display unit that displays an image; and a control unit that directs the display unit to continuously display the second image included in the early-acquired image and the second image included in the late-acquired image, of which the shading characteristics have been corrected by the correction unit, as a moving image, and to display an image based on the first image included in the early-acquired image and an image based on the first image included in the late-acquired image, of which the shading characteristics have been corrected by the correction unit, as a moving image for checking a focus in a display region of the second image.
