METHOD AND APPARATUS FOR ENCODING PIXEL INDEX AND IMAGE PROCESSING DEVICE

摘要

A method and apparatus for encoding a pixel index and an image processing device. The encoding method comprises: determining a palette corresponding to an image region to be encoded; determining, on the basis of the palette, a plurality of pixel indexes needing to be encoded in the image region to be encoded; and performing bit stream encoding on the plurality of pixel indexes, wherein bit stream encoding is not performed on the last pixel index in the case where the last pixel index appears for the first time. Thus, there is no need to encode all the pixel indexes in copy information, so that bit costs for encoding can be further reduced.
