Claim:
1. An image processing device comprising: an image acquisition section that acquires a first image and a second image, based on a first image signal and a second image signal output respectively from a first pixel group and a second pixel group that output the first image signal and the second image signal and on which a subject image is formed after passing through a first region and a second region in an imaging lens so as to be pupil-divided; a parallax computation section that computes a parallax indicating a displacement amount between each pixel in the first image acquired by the image acquisition section and respective corresponding pixels in the second image acquired by the image acquisition section; an expansion amount decision section that, for each target pixel for image processing in the first image and second image acquired by the image acquisition section, determines an expansion amount of parallax according to the parallax computed by the parallax computation section; a coefficient decision section that, for each target pixel for image processing in the first image and the second image acquired by the image acquisition section, determines a parallax conversion coefficient for converting the parallax computed by the parallax computation section into expanded parallax based on the expansion amount decided by the expansion amount decision section; an image processing section that performs processing on the target pixels to expand parallax based on the parallax conversion coefficient determined by the coefficient decision section; a generation section that generates a first display image based on an image signal output from an image pick-up device including the first pixel group and the second pixel group, and generates a second display image for use in focus verification based on the first image and the second image; a display section that displays images; and a display controller that controls the display section so as to display the first display image, and to display in a display region of the first display image the second display image including an image in which processing to expand parallax has been performed on the target pixels.
