IMAGE PROCESSING DEVICE, IMAGING DEVICE, IMAGE PROCESSING METHOD, AND COMPUTER READABLE MEDIUM

摘要

An image processing device includes: a coefficient decision section that, for each of target pixels in a first image and a second image, decides on a parallax conversion coefficient to convert a parallax computed by a parallax computation section into a parallax visually confirmable that the first image and the second image are within the first parallax range in cases determined by a first determination section to be within the first parallax range, and that decides on a parallax conversion coefficient to convert the parallax into a parallax visually confirmable that the first image and the second image are outside the first parallax range in cases determined by the first determination section to be outside the first parallax range; and an image processing section that performs image processing on the target pixels based on the parallax conversion coefficient decided by the coefficient decision section.

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 representing a displacement amount between each of the pixels of the first image and the corresponding pixels of the second image acquired by the image acquisition section; a first determination section that determines whether or not a target pixel for image processing is within a first parallax range satisfying a specific condition; a coefficient decision section that, for each of the target pixels in the first image and the second image acquired by the image acquisition section, determines a parallax conversion coefficient to convert the parallax computed by the parallax computation section into a parallax by which it is visually confirmable that the first image and the second image are within the first parallax range in cases determined by the first determination section to be within the first parallax range, and that determines a parallax conversion coefficient to convert the parallax computed by the parallax computation section into a parallax by which it is visually confirmable that the first image and the second image are outside the first parallax range in cases determined by the first determination section to be outside the first parallax range; an image processing section that performs image processing on the target pixels 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 an image in which the image processing has been performed on the respective target pixels in 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 generated by the generation section and to display the second display image generated by the generation section in a display region of the first display image.
