A method, apparatus, system and machine-readable medium for generating a composite output image based upon multiple input images. In one embodiment, a first display location on a display panel is located. A first function is performed to generate a first pixel of the output image for display at the first display location if a first image and a second image are both active at the first display location. A second function is performed to generate the first pixel of the output image if only the first image or only the second image is active at the first display location. In one embodiment, the first image is active at the first display location if the first display location is located within a first display area on the display panel where the first image is to be displayed, the second image is active at the first display location if the first display location is located within a second display area on the display panel where the second image is to be displayed.

Method and apparatus for processing video and graphics data to create a composite output image having independent and separate layers of video and graphics

The invention is a method and apparatus for processing image data stored in a memory. A read interface circuit is coupled to the memory to transfer a patch of the image data from the memory to a buffer. A scale filter is coupled to the read interface circuit to scale the image data in the patch from the buffer. A receive circuit is coupled to the scale filter to re-organize the scaled image data.

Format conversion using patch-based filtering

The present invention is a method and apparatus for converting scan rates of image data in a memory. A buffer stores a source image data. A scaling filter is coupled to the buffer to scale the source image data.
