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 5):
The automatic setting method according to  claim 1 , further comprising:\n projecting a third reference image onto the projection plane at the position corresponding to the valid identification region by the first projection unit; capturing 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; analyzing the third captured image to obtain four reference coordinates of the four reference grid points in the third captured image; generating a grid point-filled image according to the four reference coordinates of the four reference grid points, and projecting 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; capturing the grid point-filled image on the projection plane by the first image capturing unit so as to obtain a fourth captured image, and analyzing the fourth captured image to obtain a plurality of grid point coordinates of the grid points in the fourth captured image; and establishing a first coordinate conversion relation between the first projection unit and the first image capturing unit according to the plurality of grid point coordinates.
