Abstract:
A projection system including a processing device and a first projector is provided. The first projector includes a first projection unit and a first image capturing unit. The first projection unit is configured to sequentially project a first reference image and a second reference image. The first image capturing unit is configured to sequentially obtain a first captured image and a second captured image. The processing device is adapted to compare the first captured image and the second captured image to obtain a position of an image region having a pixel value change among the first captured image and the second captured image. The processing device defines the position of the image block having the pixel value change as a valid identification region. In addition, an automatic setting method is also provided.

Claim (Index 15):
The projection system according to  claim 14 , further comprising:\n a second projector, coupled to the processing device, wherein the second projector comprises: a second projection unit; and a second image capturing unit, configured to capture a part of the third reference image on the projection plane to obtain a fifth captured image, wherein the processing device analyzes the fifth captured image to obtain another four reference coordinates of the four reference grid points in the fifth captured image, wherein the processing device establishes a second coordinate conversion relation between the first projector and the second projector according to the four reference coordinates and the another four reference coordinates of the four reference grid points.
