Moving image combining apparatus combining computer graphic image and at least one video sequence composed of a plurality of video frames

摘要

A coordinate light source calculating unit 103 calculates 3D coordinates for points forming one or more objects and performs clipping. A rendering unit 104 performs rendering and outputs the formed CG image to a frame buffer 108. The coordinate light source calculating unit 103 calculates 3D coordinates forming a video display surface. A perspective projection unit 105 calculates 2D coordinates for each point forming the video display surface. An image decoder 106 decodes a video frame, and an image transform unit 107 transforms this image and outputs it to the frame buffer 108, enabling the video frame to be pasted onto the CG image.
