Claim 15:
16. A non-transitory computer-readable storage medium, wherein a computer program is stored on the non-transitory computer-readable storage medium, and the computer program is configured to, when executed by a processor, cause the processor to:
determine whether a number of written rows of source image data in a Double Data Rate synchronous dynamic random access memory (DDR) is a preset number of rows or a stop write number of rows, the preset number of rows being an integer multiple of a 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;
when the number of written rows of source image data in the DDR is the preset number of rows or the stop write number of rows, read 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, a number of rows, and a number of columns of the current image block; and
perform compression on the source image data of the current image block to obtain compressed data, and write the compressed data into the DDR.
