摘要

The image sequence color space that the frame sequence of moving image data is divided into tile images sequence (250) and ceramic tile (250) converts, to generate YCbCr image sequences (252) (S10). Each frame, which is downscaled, is then subjected to compression by 1/2 (S12) multiplied by its length and width, thus generates the reference picture (S14) of the compressed data of (260). (260) it compressed data decoded reference pictures and has decompressed and is similar to picture display times, to reproduce in YCbCr images as reference picture, difference image sequence (262) is in original YCbCr image sequences (252) and generates reference picture (S16). Then, by the generation (S18) of compressed data (266) difference image, and by data (268), it is the compressed data differential image of the reference picture (260) and (266) by coupling compressed data, generates every 4th ceramic tile picture frame (S20).
