ABSTRACT:
Apparatus includes unit storing CG data containing data about coordinate transformation, camera, geometry, light source, and texture, unit transforming coordinate system of CG data into camera-coordinate system, unit calculating intersections of object and ray vectors passing through sampled points, unit calculating 3D motion vectors, unit calculating color values at intersections, unit assigning object IDs of intersections at 3D coordinates to intersections, unit projecting intersections and 3D motion vectors onto plane, and calculating 2D coordinates at intersections and 2D motion vectors at intersections, unit storing 2D coordinates, 2D motion vectors, color values, and object IDs together as low-resolution video data, unit calculating intermediate-resolution video data by superimposing low-resolution video data of current frame onto low-resolution video data of frames temporally different from current frame, unit calculating high-resolution video data by filtering intermediate-resolution video data, unit storing high-resolution video data, and unit presenting high-resolution video data.
