ABSTRACT:
An image processing system comprises a processing circuitry operable to receive a digital image and a line buffer circuitry communicatively coupled to the processing circuitry, the line buffer circuitry comprising a plurality of line buffers. The processing circuitry performs cross talk correction on a first pixel during a first pass to generate a first cross talk corrected pixel, wherein said first pixel is received from a first line buffer of the plurality of line buffers. During the first pass, the processing circuitry further stores the first cross talk corrected pixel in the line buffer circuitry, retrieves the first cross talk corrected pixel from the line buffer circuitry, and uses the first cross talk corrected pixel to perform cross talk correction on a second pixel to generate a second cross talk corrected pixel, wherein the second pixel is received from a second line buffer of the plurality of line buffers.
