The invention discloses a method, a device and a chip for processing an image based on multistage jitter, and the method comprises the steps: carrying out the first-stage jitter operation of pixels in the image through a first-stage jitter algorithm, and obtaining a first-stage jitter result of the pixels in the image; according to the first-level jitter result of the pixels in the image, second-level jitter operation is carried out on the pixels in the image after the first-level jitter operation is carried out through a second-level jitter algorithm, and a second-level jitter result of the pixels in the image is obtained, that is, two-level jitter operation is carried out on the pixels in the image, and jitter operation is carried out every time the jitter operation is carried out. The bit widths of the obtained images are sequentially reduced, and the generation of mode noise and the occurrence of uneven gray scales can be reduced when the pixels of the images are jittered, so that the brightness distribut
