Being video image processing method for decreasing the false contour effect in regard to the display by the video image processing

摘要

The invention relates to a method and apparatus for processing video pictures, in particular for large area flicker effect reduction. This method concerns a new coding called Parallel Peak Coding. The general idea of the Parallel Peak Code is to have almost always the same energy in two packets of light and to encode the code words for these two packets differently so that changes in sub-field code word will not appear in the two packet code words simultaneously. This aims at reducing the false contour effect.
