<p>PROBLEM TO BE SOLVED: To suppress the amount of stored replay data and to generate a replay image for a long time by storing position data or angle data as replay data after reducing the number of bits and performing replay processing of an object on the basis of these data. SOLUTION: The position data or angle data of the object are stored in a replay data storage part 142 after reducing the number of bits. For example, the position data are reduced from 32 bits to 20 bits or angle data are reduced from 14 bits to 12 bits by omitting or rounding-off. In replay processing, these position data or angle data are read out of the replay storage part 142 by a reading part 122 of a replay processing part 120 and the replay image is generated by replay processing. Thus, the storage capacity of the replay data storage part 142 to be used can be reduced.</p> |
