Abstract:
A projection system and a method for calibrating display image are provided. The method includes: setting a correction image having identification patterns, and establishing first coordinate information of the identification patterns; using a projection device to project the correction image on a display screen; performing an image capturing operation to the correction image and the display screen to obtain a captured image; calculating second coordinate information of the identification patterns in the captured image, and calculating coordinate translation information according to the first coordinate information and the second coordinate information; calculating boundary information of the display screen according to a plurality of boundary coordinate values of the display screen in the captured image and the coordinate translation information, such that the projection device adjusts a size of a projection image for corresponding to the display screen according to the boundary information.

Claim (Index 11):
The projection system as claimed in  claim 10 , wherein the controller comprises a first controller and a second controller,\n the first controller is disposed in the handheld electronic device, coupled to the image capturing device, and configured to:\n set the correction image, and establish the first coordinate information of the identification patterns; \n calculate the second coordinate information of the identification patterns in the captured image, and calculate the coordinate translation information according to the first coordinate information and the second coordinate information \n calculate boundary information of the display screen according to the boundary coordinate values of the display screen in the captured image and the coordinate translation information; \n the second controller is coupled to the first controller of the handheld electronic device and the projection device, and is configured to receive the boundary information from the handheld electronic device, and adjust the size of the projection image for corresponding to the display screen according to the boundary information.
