Abstract
A calibration system and method for a display optical system including a projector and a projection screen. A calibration camera is inserted between the projector and the screen to receive the radiation directly from the projector. The image focused by the camera lens is captured by a charge-coupled device, and processed by a controller. The result is fed back to the image generator of the projector for further improvement in the image quality.
