ABSTRACT:
A method of correcting a video signal includes retrieving a correction data from a respective one multiple memory devices; reordering the correction data to a predetermined order for a particular segment; and interpolating multiple correction data so that all pixels in the particular segment have a corresponding one of the correction data. An apparatus for correcting video comprises multiple memory devices, each having multiple correction data; a cross-bar switch that reorders at least some of the data to a predetermined order for a particular segment; and an interpolator that calculates multiple interpolated correction data. One of the correction data corresponds to one of multiple pixels in the segment.
