ABSTRACT:
An image special effect device includes: a graphic processor and a video processing block; the graphic processor converting coordinates in virtual three-dimensional space into two-dimensional coordinates on a display screen in accordance with a supply of information on the shape of a model in the virtual three-dimensional space, computing texture coordinates of an image that is pasted on the display screen and a reduction rate of the model on the display screen, and outputting information on the texture coordinates and reduction rate from an image data output unit; the video processing block writing input video data YUV into a memory after filtered by using a pre-filter coefficient corresponding to information on the reduction rate supplied from the graphic processor, and reading out the video data from the memory by using the supplied texture coordinates as information of read-address.
