Abstract: A pixel selection unit calculates deviation values indicating degrees of deviation of a real depth from a reference depth with respect to respective pixels based on a reference depth restored image reproduced from captured images using a PSF and the captured images. The pixel selection unit selects a depth indicating pixel based on changes of the deviation values of the pixels arranged in a pixel scanning direction. Thereby, accuracy of a depth displayed in a depth map may be increased.
