  • Publication number: 20220201340
    Abstract: The present disclosure provides an image processing device. The image processing device includes a multimedia processor and a frame buffer compressor. For example, the frame buffer compressor performs a first compression on first image data including at least a most significant bit (MSB) of the image data of the pixel. The frame buffer compressor performs a second compression on second image data including at least a least significant bit (LSB) of the image data of the pixel. According to techniques described herein, a compression type of the first compression (e.g., a compression type based on a constant bit rate (CBR) mode, fixed bit coding, quad-tree coding, etc.) is different from a compression type of the second compression (e.g., a compression type based on a variable bit rate (VBR) mode, Golomb-Rice coding, Huffman coding, etc.).
