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 14):
The projection system according to  claim 10 , wherein the processing device projects a third reference image onto the projection plane at the position corresponding to the valid identification region by the first projection unit,\n wherein the processing device captures the third reference image on the projection plane by the first image capturing unit to obtain a third captured image, wherein the third reference image has four reference grid points arranged in a quadrangle, wherein the processing device analyzes the third captured image to obtain four reference coordinates of the four reference grid points in the third captured image, wherein the processing device projects the grid point-filled image onto the projection plane by the projection unit, wherein the grid point-filled image comprises a grid point array formed by a plurality of grid points, wherein the processing device captures the grid point-filled image on the projection plane by the first image capturing unit so as to obtain a fourth captured image of the projection plane, and analyzes the fourth captured image to obtain a plurality of grid point coordinates of the grid points in the fourth captured image, wherein the processing device establishes a first coordinate conversion relation between the first projection unit and the first image capturing unit according to the plurality of grid point coordinates.
