Claim 15:
16. A method of operating an image signal processor, the method comprising:
receiving first image data for pixel data in a graphic image;
extracting an alpha value α of the graphic image from the first image data and generating an alpha map for the alpha value α;
receiving the alpha map and second image data for pixel data in a video image;
performing computation on the second image data using the alpha map to generate multiply data;
performing compression on the multiply data to generate second compressed data and performing compression on the first image data to generate first compressed data; and
performing alpha-bending by mixing the first compressed data and the second compressed data; and
storing the second compressed data in a memory.
