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 1):
A method for calibrating a display image, adapted to a projection system, wherein the projection system comprises a projection device and a display screen, the method for calibrating the display image comprising:\n projecting a correction image on the display screen by using the projection device, wherein the correction image has N identification patterns, and N is a positive integer greater than 3; performing an image capturing operation on 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 first coordinate information of the identification patterns 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; and adjusting a size of a projection image by the projection device for corresponding to the display screen according to the boundary information.
