Video image streams and graphic objects combining process for automobile, involves combining values of image planes pixels and determined transparency ratio to determine value of each pixel of resulting video image streams

摘要

The process involves determining a value of each of several image planes according to position and size of each clip art or video image streams. A transparency ratio for each pixel is determined based on a specific transparency ratio. The values of the image planes pixels and the determined transparency ratio are combined by a video/graphics accelerator (12) for determining value of each pixel of resulting video image streams. An independent claim is also included for a device to combine resulting video image stream, input video image stream and a clip art.
