Abstract

An image blending system and a method for image blending are provided. The image blending system includes a plurality of projection devices, an image capturing device, a blending device, a video input module, and a computing module. The projection devices project a desired image. The image capturing device is configured for image capturing from a projection surface. The captured image has an image capturing coordinate system based on a resolution of the captured image. The projection devices receive an input video signal transmitted from the blending device for projection, and the input video signal has an input video coordinate system based on a resolution of the input video signal. The computing module calculates for obtaining a plurality of mapping relationships according to the image capturing coordinate system and the input video coordinate system, and obtaining an image blending relationship through the mapping relationships and an overlapping area of projection regions.
