Abstract
A device, system and method for photometric compensation of images provided by a display device. A display device is controlled to provide colors, the display device configured to provide images according to the colors of the display device. A camera acquires respective images of the colors provided by the display device. A per-pixel correction function for modifying image data used by the display device to provide the images is determined based on: the respective images of each of the colors acquired by the camera corrected into the HVS model using a predetermined color-relationship between the camera and a Human Visual System (HVS) model for the colors of the display device. The display device is controlled to provide the images using the image data as corrected using the per-pixel correction function.
