Abstract
The present invention provides an image generation system and program that apply shading for producing a cel animation type of image, with a reduced processing load. Brightness information is set for each pixel of a two-dimensional image that is obtained by perspective transformation of a three-dimensional object, based on brightness information set for that three-dimensional object, the two-dimensional image is divided into a plurality of areas based on the thus-set brightness information, and stepped shading is applied in units of the thus-divided plurality of areas. This brightness information could be set beforehand or it could be calculated in real-time, based on a given condition. The system could also comprise means for determining the pixels to be rendered by comparing the brightness information of each pixel with a given threshold value, then performing adjustment processing on the color information of the pixels to be rendered, based on color information that acts as a reference. This threshold value can be varied in accordance with the number of steps of shading, and adjustment processing can be performed a plurality of times on color information of pixels to be rendered.
