Abstract
The disclosure provides a method for adjusting pixel values of blending image. The method includes projecting, on a projection surface, a first projection image onto a first projection range and a second projection image onto a second projection range by a first projector and a second projector, and blending the first projection image and the second projection image to generate a blending image; calculating positions of a plurality of boundaries of the first projection range and the second projection range; adjusting a range of an overlapping area between the first projection range and the second projection range; and adjusting image parameters of a non-overlapping area outside the overlapping area, to enable pixel values of the non-overlapping area to be close to pixel values of the overlapping area.
