Abstract:
An apparatus including a data processing system for processing a serial stream of multiple bit data sets which represent an array of pixels corresponding to a two-dimensional image including correcting for defective pixels individually or in groups, comprising:a first data processing circuit configured to receive and process together a plurality of successive sets of image data with a corresponding plurality of successive sets of correction data and in accordance therewith provide a plurality of successive sets of corrected image data, wherein said plurality of successive sets of image data represents a plurality of pixels corresponding to a two-dimensional image, said plurality of successive sets of correction data represents a plurality of correction factors, each one of said plurality of correction factors corresponds to a respective one of said plurality of pixels and each one of said plurality of successive sets of correction data includes a first data subset which indicates whether said respective one of said plurality of pixels is defective; and a first data selection circuit, coupled to said first data processing circuit, configured to receive and select between individual ones of said plurality of successive sets of corrected image data and individual ones of said corresponding plurality of successive sets of correction data and in accordance therewith provide a first plurality of successive sets of selected data, wherein an individual one of said first plurality of successive sets of selected data includes a corresponding individual one of said plurality of successive sets of correction data when said first data subset indicates that said corresponding respective one of said plurality of pixels is defective, and wherein said individual one of said first plurality of successive sets of selected data includes a corresponding one of said plurality of successive sets of corrected image data when said first data subset does not indicate that said corresponding respective one of said plurality of pixels is defective.
