ABSTRACT:
A character screen information generating unit (34) has a function also serving as a spotlight information generating unit and outputs spotlight information for brightness toward a brightness information converting unit (30). The brightness information converting unit (30) uses this spotlight information for brightness to convert brightness information. A shading computation unit (24) uses the converted brightness information and color information of an object to determine color information to be displayed on a display at each pixel. A depth cueing computation unit (26) uses depth information to make a depth cueing computation relative to the determined color information. Thus, a pattern such as headlight can be displayed in the form of spotlight. Further, such a spotlight display can reflect by the depth information. There may further be provided a depth information converting unit for converting the depth information by the use of spotlight information for depth.
