Abstract:
1. A method for providing a distortion corrected video signal, comprising the steps of: providing at least one test pattern having a plurality of features disposed thereon; providing an image capture device having a camera and an image processor; capturing at least one calibration image of the test pattern using the camera; analyzing the at least one calibration image using the image processor to provide a calibration data table; and storing the calibration data table in the image processor, wherein the step of analyzing the at least one calibration image using the image processor to provide a calibration data table includes the steps of storing known geometric features of the least one test pattern in the image processor, identifying portions of the calibration image that correspond to the features of the test pattern to provide calibration image feature position data, and analyzing the calibration image feature position data based on the known geometric features of the at least one test pattern to provide the calibration data table.
