PROBLEM TO BE SOLVED: To provide a picture processor and its method capable of obtaining effective plotting results by small calculation quantity. SOLUTION: The picture processor is provided with a vertex unit processing part 21 for calculating a filter processing parameter on the basis of a normal vector and a sight line vector provided in each vertex, a rasterizing part 22 for rasterizing vertex information as a fragment unit and rasterizing the filter processing parameter, a fragment unit processing part 23 for performing arithmetic processing on the basis of the information rasterized as the fragment unit, a memory part 24 for storing the rasterized filter processing parameter in each pixel and storing the output information from the fragment unit processing part 23, and a picture processing part 25 for finding a suitable filter kernel on the basis of the value of the filter processing parameter stored in the memory part 24 and applying filter processing to the information stored in the memory part 24 on the basis of the found filter kernel.
