Abstract
In one embodiment, a computing system may access a dead pixel position corresponding to a dead pixel of a display. The system may access an image and modify the image by applying a mask to a pixel region of the image containing a particular pixel value with a position that corresponds to the dead pixel position. The mask may include an array of first scaling factors for scaling pixels values in the pixel region. The array of first scaling factors may be configured to brighten one or more of the pixel values surrounding the particular pixel value. The system may cause the modified image to be output by the display.
