PROBLEM TO BE SOLVED: To perform filtering that gives visual effects corresponding to depth to a scene in a virtual three-dimensional space using a simple processing. SOLUTION: A scene in the virtual three-dimensional space is divided into a plurality of areas F0 to F4 in accordance with depth from a prescribed viewpoint, and a filter level α is set in each divided area. Filter processing that gives such visual effects as blurring to each area of the scene is carried out at a degree corresponding to the filter level, and the scene subjected to the filter processing is displayed on a display device 34. A single filter level is defined to each area obtained by dividing the scene according to depth, calculation is conducted in regard to a pixel contained within the area with common conditions, and the processing is therefore relatively simple. |
