<p><P>PROBLEM TO BE SOLVED: To facilitate management of the execution timing of decompression processing in moving video reproduction control in an image processor, where IP compression video data and IPB compression video data are used mixedly for production, and to lessen the control load of moving video reproduction control, as much as possible. <P>SOLUTION: When a movie image based on IPB movie data is reproduced and displayed, a CPU designates decompression twice for GCL in the first frame interval (F1). In the first frame interval (F1), the GCL 104 decompresses pictures I1 and P1 according to twice the instructions of decompression. Subsequently, the CPU outputs display instruction and decompression designation repeatedly for each frame interval, and the GCL outputs a video signal, in response to display instruction and then decompresses and develops the picture, in response to decompression instruction. A production moving video completing the production content is generated by the IPB movie data, and background moving video that is not completed of production content is generated by the IP movie data. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
