A first set of methods is adaptive and region-based and comprises dividing a digital input image comprised of input image luma pixels into a plurality of blocks, and for each of the blocks, applying certain statistical analyses and computations to produce output image pixel data, communicating the output image pixel data to an image display device, and displaying the output image. A second set of methods is adaptive and uses human vision basis functions. A device for producing an output image with enhanced contrast is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive contrast in image processing and display","description":"Methods of producing an output image with enhanced contrast are disclosed.
