Patent ID: 7843461

Claim:
A broadcast and commercial image special effect device, comprising: a controller; a memory unit connected to said controller; a graphic processor, connected to said memory unit, in which a programmable shader is installed; and a video processing block, connected to said controller, configured with hardware circuits for outputting YUV video data; said graphic processor being programmed to execute processing that converts coordinates in virtual three-dimensional space into two-dimensional coordinates on a display screen in accordance with a supply of information on a shape of a model in the virtual three-dimensional space and computes texture coordinates of an image that are pasted on the display screen and a reduction rate of the model on the display screen, and processing that outputs said texture coordinates (X,Y) as stored in two bits of R data, eight bits of G data and eight bits of B data and that outputs said reduction rate as stored in remaining bits of the R data from an image data output unit to said memory unit; said video processing block including a pre-filter that performs filtering of input video data by using a pre-filter coefficient corresponding to the reduction rate supplied thereto by said controller, a memory to which the video data filtered by said pre-filter is written, a control circuit that reads out the video data from said memory by using supplied texture coordinates as read-address information; and wherein said texture coordinates output from said graphic processor and stored in said memory unit is supplied to said control circuit of said video processing block from the memory unit by the controller, and said reduction rate output from said graphic processor and stored in said memory unit is supplied to said pre-filter of said video processing block from the memory unit by the controller.
