Abstract

A projection device (110) including a processor circuit (112) is provided. A reverse-warped image is generated by the processor circuit (112) according to an input image and a second mapping table. The projection device (110) is adapted to project the reverse-warped image onto the projection screen (120). The second mapping table is converted from a first mapping table according to a plurality of warped feature points caused according to a first calibration pattern and a second calibration pattern. A projection system (100) and an image calibration method are also provided. Therefore, an undistorted and a non-warped image may be formed on a curved projection screen and be viewed by a viewer.
