  • Image processing method and apparatus, and related assembly
    Patent number: 11930198
    Abstract: Provided is an image processing method, which includes: determining whether the number of written rows of source image data in a DDR is a preset number of rows or a stop write number of rows, the preset number of rows being an integer multiple of the number of rows of an image block determined according to a compression condition, and the image block being any image block in an image block matrix determined on the basis of an entire frame of image; if yes, reading the source image data of the current image block from the DDR on the basis of a first read address of the current image block, the number of rows, and the number of columns; and performing compression on the source image data of the current image block to obtain compressed data, and writing the compressed data to the DDR.
    Type: Grant
