System and method for automatic calibration of a display device

摘要

A method for evaluating colorimetry of viewing conditions affecting a viewer and calibrating a display device used by the viewer relative to an environment surrounding the display device is based on measuring display colorimetry data and the colorimetry of the viewing conditions and generating display and viewing condition colorimetry data, wherein the viewing conditions include the effect of surround light originating from the environment surrounding the display device and impinging upon the viewer rather than the display device. A color conversion function is calculated from the display colorimetry data and the viewing condition colorimetry data, where the color conversion function is capable of transforming an input video signal into a transformed video signal that shows an improved image based on the colorimetry of the display device and the colorimetry of the viewing conditions. The color conversion function performs color conversion of the input video signal, thereby generating the transformed video signal which is displayed on the display device.
