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 3):
The automatic setting method according to  claim 2 , wherein the step of comparing the first captured image and the second captured image to obtain the position of the image region having the pixel value change among the first captured image and the second captured image, and defining the position of the image block having the pixel value change as the valid identification region comprises:\n subtracting pixel values of a plurality of pixels of the first captured image and the second captured image from each other to obtain a pixels-subtracted image; and analyzing the pixels-subtracted image to determine a region having the pixel values greater than a threshold value in the pixels-subtracted image, and defining the region having the pixel values greater than the threshold value as the valid identification region.
