摘要:
Method and apparatus for the selective scaling, such as magnification and reduction, of video images stored as collections of image pels in a video memory. A lookup table is provided for determination of the values of the scaled image pels. A framing matrix of unscaled image pels is established for each scaled image pel. The framing matrix for the scaled image pels determines the outputs read out of the lookup table, and derivatively, determines the values of the scaled image pels. The scaled image pels are stored in the video memory for subsequent display or processing.
