PROBLEM TO BE SOLVED: To provide technical means for reducing a processing load during interpolating attribute data of a pixel on the basis of attribute data of a vertex.SOLUTION: A setup part 22 merges an NZ component and 1/W component of a three-dimensional positional coordinate attribute POS with a U component and a V component of a texture coordinate attribute UV. After that, the setup part 22 calculates an interpolation coefficient of each of the U component, the V component, the NZ component and the 1/W component. An interpolator 241 of an interpolation calculation part 24 performs an interpolation calculation of each of the U component, the V component, the NZ component and the 1/W component in parallel. The interpolation calculation part 24 separates the U component and the V component after the interpolation calculation from the NZ component and the 1/W component after the interpolation calculation. |
