ABSTRACT:
A method of determining a gamma curve of a display device includes identifying a region of interest of a display surface of the display device. A centroid of the region of interest is calculated. A plurality of input levels is applied to the display device to generate a corresponding plurality of displayed images on the display surface. At least one image of each of the displayed images is captured with a camera. A gamma curve of the display device is calculated based on the captured images and the centroid.
