PHOTOGRAPHING APPARATUS, PHOTOGRAPHING METHOD, IMAGE PROCESSOR, IMAGE-PROCESSING METHOD, AND PROGRAM

A photographing apparatus includes an image sensor which images a plurality of images; an image processor configured to set one image as a reference image and each remaining image as a comparative image; an image processor configured to generate a reference map divided into blocks; an image processor configured to generate a comparative map divided into blocks; an image processor configured to generate a change-detection map indicating coinciding or non-coinciding blocks between the reference map and the comparative map, per each respective block, upon the reference map and the comparative map being compared; an image processor configured to obtain a synthesized image of the images; and an image processor configured to replace at least a part of the synthesized image with a corresponding part of the reference image based on the change-detection map.
