Patent ID: 7508387

Claim:
A method of calibrating an imaging display system comprising the steps of: forwarding a display test pattern from a display adapter to a display of the display system, the display test pattern including a measurement field comprising approximately 10% of a total number of pixels displayed by the display, wherein the measurement field can be placed at different regions of a display screen of the display; causing 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); receiving luminance and color values from a plurality of photosensors associated with the display screen, said photosensors detecting distinct luminance and color levels at the different regions of said screen; from said detected luminance and color levels, determining a plurality of luminance and color correction factors by comparing the detected luminance and color values to reference luminance and color data; and applying the determined luminance and color correction factors to the different regions of said screen so as to adjust luminance and color of said screen at the different regions, each region spanned by a corresponding measurement field.
