Abstract
An information handling system includes a display for displaying an image and a processor. The processor is configured to receive an input image, determine if a pixel is in an edge region, generate an anti-reflective image by applying an edge preserving blue noise pattern to pixels within the edge region, and applying a mean persevering blue noise pattern to pixels outside of the edge region. The anti-reflective image is provided to the display. When displayed, the anti-reflective image reduces artifacts caused by reflection or glare on the display.
