The invention relates to the technical field of image restoration, and provides an image super-resolution acceleration method and system based on a reference table, and the method comprises the steps: obtaining a low-resolution input image and a reference table; the reference table comprises a plurality of records, and any record comprises complexity score reference values and image quality reference values which are in one-to-one correspondence; the complexity score reference values and the image quality reference values in one-to-one correspondence are obtained by calculating complexity scores and image quality of the same sample image; dividing the low-resolution input image into a plurality of low-resolution image blocks; inputting each low-resolution image block into a multi-exit SR network to obtain a plurality of super-resolution image blocks; and combining the plurality of super-divided image blocks to obtain a high-resolution output image. According to the technical scheme, the problem of poor adapta
