  • System and method for light compensation in a video panel display
    Patent number: 8610781
    Abstract: A system for adjusting the light uniformity of a monitor. The system comprises a camera for capturing a test pattern image on a display of the monitor and a controller configured to select the test pattern image and to cause the monitor to display the selected test pattern image. The controller receives the captured image from the camera and compares pixel values from the captured image to known pixel values associated with the selected test pattern image. The selected test pattern image has an ideal uniform light distribution and the captured image has a non-uniform light distribution. In response to the comparison, the controller calculates a compensation light distribution that may be combined with the non-uniform light distribution to generate a resulting image on the display of the monitor having a resulting light distribution that approximates the ideal uniform light distribution.
