Patent ID: 8339385

Claim:
A self-calibrating imaging display system comprising: a display having a screen; a display adaptor communicatively linked to the display; a plurality of photosensors associated with the screen, the plurality of photosensors detecting luminance and color values correlating to distinct luminance and color levels at different regions of the screen; a calibration module, the calibration module directing the display adaptor to generate and forward to the display a display test pattern including a measurement field comprising approximately 10% of a total number of pixels displayed by the screen and cause the measurement field to be stepped through a sequence of values from zero and increasing at each step up to a maximum display driving level (DDL), wherein the measurement field can be placed at the different regions of the screen, the calibration module receiving from the plurality of photosensors inputs correlating to the luminance and color values, the calibration module determining a plurality of luminance and color correction factors by comparing the luminance and color values to reference luminance and color data, different ones of the luminance and color correction factors being applied to different regions of the screen which are applied to adjust luminance and color of the screen at the different regions, each of the different regions spanned by a corresponding measurement field.
