IMAGE PROCESSING APPARATUS AND CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus which generates encoded data with high encoding efficiency while re-focusing an image to a desired ROI (region of interest).SOLUTION: The image processing apparatus includes: a generation part for calculating an average vale of values of pixels at the same position within sub images of viewpoints forming multi-viewpoint image data to generate an average image having the calculated average value as a pixel value of a corresponding position; a detection part 106 for detecting at least one ROI common for the sub images on the basis of contrast in each sub image and a parallax between the sub images; and a code stream generation part 111 which encodes the average image and a partial image indicated in each ROI within each sub image and forms an encoded data stream together with positional information of the ROI.
