Abstract:
A method and apparatus for providing a distortion corrected video signal. A camera is directed toward a test pattern for producing a raw video signal. An image processor is operatively connected to the camera for receiving the raw video signal. The image processor is operable to capture at least one calibration image of the test pattern using the raw video signal from the camera, analyze the at least one calibration image to provide a calibration data table, and store the calibration data table within the image processor.
