Abstract
The present invention is a method and apparatus for de-interlacing image data 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 de-interlacing circuit is coupled to the read interface circuit to de-interlace the image data in the patch from the buffer. A receive circuit is coupled to the de-interlacing circuit to re-organize the de-interlaced image data.
Claims8
A method for de-interlacing image data, the method comprising:
- transferring a vertical patch having a first size of the image data from a memory to a buffer;
- de-interlacing the image data in the vertical patch using a window of image data of size smaller than the first size;
- and
- re-organizing the de-interlaced image data.
