Method for adjusting pixel values of blending image and projection system thereof

A projecting system, comprising:

• a first projector;
• a second projector;
• and
• a processing device, connected to the first projector and the second projector, and configured to:
• control the first projector to project a first projection image onto a first projection range on a projection surface and control the second projector to project a second projection image onto a second projection range on the projection surface;
• blend the first projection image and the second projection image to generate a blending image, and calculate positions of a plurality of boundaries of the first projection range and the second projection range according to positions of a plurality of boundaries of the first projection image and the second projection image;
• adjust a range of an overlapping area between the first projection range and the second projection range on a basis of the positions of the plurality of boundaries of the first projection range and the second projection range;
• and
• adjust image parameters of a non-overlapping area outside the overlapping area in the first projection range and the second projection range, to enable pixel values of the non-overlapping area to be close to pixel values of the overlapping area.
