摘要

A projection display device for use with a curved screen as well as a fixed flat screen comprises a camera as imaging means for detecting the position of a curved screen; a computer that traces markers on the curved screen based on the signal from the camera, predicts the posture and/or position of the curved screen and produces an image based on the posture and/or position of the curved screen; and a projector for projecting the image produced by the computer onto the curved screen.
