Abstract:
Color correction technology for computing and gaming systems are discussed herein which compensate for color vision deficiency among individuals. In one example, a method includes receiving a video frame having a first non-linear transfer function and processing the video frame to have a linear transfer function. The method also includes applying a color transform to the video frame having the linear transfer function to produce at least altered color appearance parameters on selected colors that increase color perceptibility of the video frame for a colorblindness condition, and processing the video frame after the color transform to have a second non-linear transfer function and produce an output video frame. The method also includes transferring the output video frame for display on a display device.
