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.

On demand calibration of imaging displays

A self calibrating imaging display system and machine-readable storage for such systems are provided, which perform various steps. The steps include forwarding a display test pattern, where the display test pattern including a measurement field comprising approximately 10% of a total number of pixels displayed by a screen and where the measurement field can be placed at different regions of the screen. The steps also include causing the measurement field to be stepped through a sequence of values. The steps further include receiving luminance and color values from photosensors to detect distinct luminance and color levels at the different regions of the screen. The steps also include determining luminance and color correction factors by comparing the detected luminance and color values to reference luminance and color data. The steps additionally include applying the determined luminance and color correction factors to the different regions of the screen.

A self calibrating imaging display system (). The imaging display system () can include a screen () having integrated photosensors (). The photosensors can detect luminance values () correlating to luminance levels of the screen. The luminance values can be forwarded to a calibration module () which can receive the luminance values as an input and generate luminance correction factors (). The luminance correction factors can be applied to adjust the luminance of the screen. Accordingly, images can be displayed on the screen with proper luminance levels.
