Abstract
According to one embodiment, in an apparatus for generating a multi-viewpoint image, a separation unit separates a target image into a first diffuse reflection image and a first non-diffuse reflection image based on a pixel value of each pixel of the target image. The first non-diffuse reflection image has components except for the first diffuse reflection image. A first estimation unit estimates a change amount of each pixel among a plurality of first non-diffuse reflection images corresponding to viewpoints differently. A first generation unit generates a second non-diffuse reflection image by changing at least one of a shape and a luminance of each pixel of the first non-diffuse reflection image, based on the change amount of each pixel. A synthesis unit generates the multi-viewpoint image by synthesizing the first diffuse reflection image with the second non-diffuse reflection image. Each viewpoint image corresponds to each of the viewpoints.
