Abstract:
1. A method of processing a first pixel array into a second pixel array in an apparatus, the apparatus including a first register, the first register including a plurality of first register segments, the first pixel array including a first row, the first row including a plurality of first row segments, each first row segment corresponding to a respective first register segment, each first row segment including first and second pixels, the method comprising: parallel loading a signal from the first pixel in each first row segment into a first element of the corresponding first register segment of the first register; aligning the signal from the first pixel of each row segment with the second pixel of the same first row segment by serially shifting the first register; for each first register segment, arithmetically combining a signal from the second pixel of the corresponding first row segment with the signal from the first pixel of the same first row segment after the first register has been serially shifted; and outputting the arithmetically combined results as a part of the second pixel array.
