Abstract
A compact flat panel color calibration system includes a lens prism optic able to pass a narrow, perpendicular, and uniform cone angle of incoming light to a spectrally non-selective photodetector. The calibration system also includes a microprocessor operable to determine the luminance of the display based upon the information gathered by the photodetector. A software module included in the calibration system is then operable to process the luminance information in order to adjust the flat panel display.
Claims20
A system for calibrating a display, comprising:
- a lens operable to receive first and second incoming lights emitted by a display device, the first incoming light not including ambient light, the second incoming light including ambient light glaring on the display device;
- a photodetector operable to detect properties of the first and second incoming lights regardless of the location of the lens in relation to the display device;
- a microprocessor operable to generate a luminance value of the display device in response to the properties of the first and second incoming lights detected by the photodetector, the microprocessor operable to provide the luminance value in order to adjust display parameters for the display device, the microprocessor operable to generate the luminance value to compensate for ambient light glaring on the display device.
A compact flat panel color calibration system, comprising:
- means for detecting a first incoming light emitted from a display, the first incoming light not including ambient light;
- means for detecting a second incoming light emitted from a display, the second incoming light including ambient light glaring on the display;
- means for determining the color temperature of the first and second incoming lights;
- means for determining the luminance of the first and second incoming lights;
- and
- means for adjusting emissions from the display in accordance with the determinations of color temperature and luminance to compensate for ambient light glaring on the display.
A method of calibrating a display, comprising:
- receiving a first incoming light emitted by a display, the first incoming light not including ambient light;
- receiving a second incoming light emitted by the display, the second incoming light including ambient light glaring on the display;
- generating signals corresponding to the first and second incoming lights;
- determining a luminance associated with the signals;
- adjusting emissions from the display in response to the luminance to compensate for ambient light glaring on the display.
