Abstract
A self-calibrating imaging display system includes a display comprising a screen and at least one photosensor associated with the screen and generating an output signal correlating to measurements for at least one region of the screen. The system further includes a display adaptor configured for, during a calibration routine, generating a display test pattern in the at least one region of the screen comprising at least one measurement field that comprises a number of pixels less than a total number of pixels of the screen and causing the at least one measurement field to be stepped through a sequence of increasing display driving level values. The system also includes a calibration module configured for, during the calibration routine, receiving the output signal, comparing the output signal to reference data, and generating at least one correction factor based on the comparing.
