An image processing device includes an image generation unit generating a computer graphics image on the basis of computer graphics description data, an image mapping unit texture-mapping an input image to a surface of a computer graphics object drawn by the image generation unit, and a coordinate setting unit undergoing a change manipulation of a texture coordinate and storing contents of the change manipulation, in which the image mapping unit performs texture mapping by a text coordinate which is changed on the basis of contents of the change manipulation which are stored in the coordinate setting unit when texture-mapping the input image to the surface of an object.
