Summary:PROBLEM TO BE SOLVED: To render reflection with enhanced reality while maintaining a material feeling of an original image with a little data quantity in reflection mapping. SOLUTION: A reflection texture includes at least α value information as pixel information. A texture coordinate computing part 116 includes a reflection mapping texture coordinate computing part 117 finding a texture coordinate corresponding to a vertex based on a normal line vector matching the vertex. A mapping processing part 124 includes a reflection mapping processing part 117 mapping the reflection texture to an object based on the reflection mapping texture coordinate. A rendering processing part 120 includes an α multiplication processing part performing multiplication processing Cd×αs between a color value Cd of the original image and the reflection-mapped reflection texture α value αs for each pixel for finding a color value of the each pixel.
