Abstract
A combined video display and image capture system and method are disclosed. In one embodiment the system alternates between the capture period of the camera (306) and the image display (302) period to isolate the camera (306) from the display (302). Various methods are disclosed to achieve the alternation in the capture and the display periods of the system. Distortions in the captured image can be corrected using an image correction subsystem.
