VIDEO PROCESSOR AND VIDEO PROCESSING METHOD

PROBLEM TO BE SOLVED: To provide a video processor that controls frame video resolution on the basis of polygon movement when a moving image is mapped on a polygon as a texture.SOLUTION: A video processor includes a synthesis instruction unit 101, a vertex information generation unit 102, a viewpoint clip processing unit 103, a movement amount calculation unit 106, a resolution determination unit 108, an occupied area calculation unit 107, a moving image reproduction unit 109, a frame storage unit 110, and a texture mapping unit 104. On the basis of a movement amount of a polygon calculated by the movement amount calculation unit 106 and an occupying rate calculated by the occupied area calculation unit 107, the resolution determination unit 108 determines a lowering rate for lowering frame video resolution, the moving image reproduction unit 109 generates frame video with the resolution of a moving image to be reproduced lowered, and the texture mapping unit 104 maps the frame video generated by the moving image reproduction unit 109 on the polygon as a texture.
