Abstract
A storage buffer attached to an image processor for stereo image processing. The processor compares a first image and a second image. The storage buffer stores image data of the second image. The storage buffer includes: a data-shifting-hardware mechanism which while the processor compares a patch of the first image to a swath of the second image, the data shifting mechanism using hardware within the storage buffer shifts at least a portion of the swath within the storage buffer. The data-shifting hardware mechanism includes preferably digital multiplexers with respective selectable inputs from adjacent and non-adjacent columns of data within the storage buffer and selectable inputs from adjacent rows of data within the storage buffer.
