Abstract
In one embodiment, a computing system may access a dead pixel position corresponding to a dead pixel of a display. The dead pixel may be associated with one of three color channels of the display. The system may access an image and select a set of three masks based on the color channel of the dead pixel. The system may modify the image by applying the set of three masks to a pixel region of the image containing a particular pixel value with a position that corresponds to the dead pixel position. The set of three masks may be respectively applied to three color channels of pixel values in the pixel region of the image. The set of three masks may be configured to minimize an error caused by the dead pixel in an opponent color space. The system may cause the modified image to be output by the display.
