MULTI-VIEWPOINT ENCODING AND DECODING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the encoding efficiency of a parallax vector and also to reduce the computational complexity of the parallax vector by estimating the compensation of both movement and parallax when a multi-viewpoint image is encoded. SOLUTION: An image input part 5 inputs a multi-viewpoint stereoscopic image after dividing it into parts images having parallax and a background image having no parallax. Then a movement compensation part 6 estimates the movement compensation based on the moved variable between the frames or fields of the parts images. A parallax compensation part 16 estimates the parallax compensation based on the parallax amount caused between the frames or fields of the parts images. A parallax divider 17 is provided for every parts image to define one of parallax vectors obtained at the part 16 as a global parallax vector and to output a local parallax vector that is defined by subtracting the global parallax vector from other parallax vectors excluding the global one.
