PROBLEM TO BE SOLVED: To provide an image generation method capable of obtaining a beautiful filtering effect with less blurs even for a polygon in the case that the polygon which is an object is inclined in a z axis direction and is long in an inclination direction, and to provide an image generator using it. SOLUTION: Texture coordinates and an LOD (Level of Detail) value are computed by a pixel unit from object data, a filtering area of a texel read from a texture memory is decided on the basis of the texture coordinates and the LOD value, a weighted mean value corresponding to the size of the decided filtering area is obtained and a texture color to be stuck to the polygon is generated.
