The invention is applicable to the technical field of image processing, and provides an anti-vignetting method and an anti-vignetting device for a spliced image, and terminal equipment. The method comprises the steps of performing automatic exposure compensation on input light intensity of each camera according to exposure data of an image processor; splicing the images acquired by each camera after automatic exposure compensation and performing display lookup table compensation on the spliced image; and reading and judging a gray value difference at the image joint after the display lookup table compensation is performed, and performing median filtering on the gray value difference. The problem that the images acquired by the plurality of cameras are inconsistent in brightness is solved by performing automatic exposure compensation on light intensity of the image acquired by each camera, then corresponding compensation factor compensation is performed on the corresponding pixel position of the spliced image
