<p>PROBLEM TO BE SOLVED: To speedily generate a video corresponding to changes in the position of a viewpoint and the direction of line of sight when such changes occur by preventing the generation of the new view when data on the viewpoint position and the line-of-sight direction, which are newly inputted, are similar to present data. SOLUTION: An inspection part 3 compares data on the viewpoint position and the line-of-sight direction, which are newly inputted to an input part 1, with present data which are stored in a storage part 2. When they do not match with each other, the inspection part 3 stores newly inputted data in the storage part 2 and updates data in the storage part 2 and sends an update notice signal 6 showing that data are updated to a video generation part 4. When they match with each other, the inspection part 3 does not send the update notice signal. The video generation part 4 receives updated data by a data signal 5 from the storage part 2 and generates and outputs the new computer graphics video by the signal when it receives the update notice signal 6.</p> |
