ABSTRACT:
Systems and methods are provided for evaluating performance of a projector. An imaging screen is configured to produce an image of a pattern projected thereon. A camera is configured to capture and digitize the image of the pattern projected on the imaging screen. An image analyzer is configured to receive the digitized image from the camera and to analyze the received digitized image.
