Abstract
In one embodiment, method for correcting geometric distortion in an image is provided. The method comprises operating at least first and second buffers upstream of a pixel processing block in pipelined hardware to each read M×N pixels of an input image to be corrected for geometric distortion; selectively connecting one of the first and second buffers to the pixel processing block for inputting the M×N pixels contained therein to the pixel processing block; and in the pixel processing block, processing the M×N input pixels to correct for geometric distortion, the processing block being configured to output segments 1×L pixels wide of an output image that is corrected for geometric distortion; wherein values for M and N are selected to define a minimum block size in the input image required to produce each current 1×L segment in the output image by an algorithm to correct for geometric distortion in the input image.
