Title: PALETTE CODING METHOD AND APPARATUS AND IMAGE PROCESSING DEVICE
Abstract:
Provided are a palette coding method and apparatus and an image processing device. The coding method comprises: determining a palette, comprising multiple pixel values, of a to-be-coded image area; for a pixel value in the palette, determining coding information of the pixel value according to the difference between the pixel value and a previous pixel value; and performing bit stream coding on the coding information corresponding to the pixel value. Therefore, the bit number required by palette coding can be reduced and the bit cost of coding is lowered.
