Abstract

A sub-image extractor extracts a target sub-image from a light field image. A partial area definer defines a predetermined area in the target sub-image as a partial area. A pixel extractor extracts pixels from the partial area, the number of pixels meeting correspondence areas of a generation image. The pixel arranger arranges the extracted pixels to the correspondence areas of the generation image in an arrangement according to the optical path of the optical system which photographs the light field image. Pixels are extracted for all sub-images in the light field image, and are arranged to the generation image to generate a reconstruction image.

First claim

What is claimed is:

1. An image processing device comprising:
an image obtainer that obtains a multi-view image in which sub-images from viewpoints are aligned;
a clipper that clips partial images from the sub-images;
a generator that generates a reconstruction image by arranging the partial images based on an alignment position of the sub-images corresponding to the partial images;
a distance setter that sets a re-focal length of the reconstruction image;
an interval dete…
