System and method for reflection mitigation using blue noise pattern

摘要

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.

1. A method for reducing artifacts caused by reflection or glare in displayed images, comprising:
receiving an input image; determining if a pixel of the input image is in an edge region; generating an anti-reflective image by applying an edge preserving blue noise to pixels of the input image within the edge region, and applying a mean preserving blue noise to pixels of the input image outside of the edge region, wherein the edge preserving blue noise adds noise to a first pixel cluster on a first side of an edge such that the overall appearance of the noise added to the first pixel cluster is a first color and the noise added to the pixels of the pixel cluster immediately adjacent to the edge corresponds to the first color and adds noise to a second pixel cluster on a second side of the edge such that the overall appearance of the noise added to the second pixel cluster is a second color and the noise added to the pixels of the pixel cluster immediately adjacent to the edge corresponds to the second color; and displaying the anti-reflective image on a display such that artifacts caused by reflection or glare on the display are reduced compared to displaying the input image on the display.
