Abstract
Methods and a system for pixel-by-pixel correction of diffuse reflected and specular reflected light on a display device of an information handling system. Voltage values of pixels of the display device are measured by sensors. Measured voltage values of a pixel are converted to a digital value. A digital correction value calculated based on whether diffuse reflected light or diffuse reflected light and specular reflected light is found on the pixel. A sigmoid transfer function and discrete sharpening filter is performed on the pixel, if the digital correction value is less than zero.
