Abstract
The disclosure provides an image blending method. The method includes projecting a plurality of images onto a projection surface, respectively, wherein an image of the first portion of the first image and an image of the first portion of the second image projected onto the projection surface overlap each other in the first overlapping area on the projection surface; the image parameters of all pixels of the first non-overlapping area and the second non-overlapping area are adjusted according to the position of the first non-overlapping area and the position of the second non-overlapping area, such that the black-level brightness of the first non-overlapping image in the first non-overlapping area of the first image and the black-level brightness of the second non-overlapping image in the second non-overlapping area of the second image are close to the black-level brightness of the first overlapping image in the first overlapping area.
