Patent ID: 8866837

Claim:
In a computing device that includes a processor and memory, a method comprising: determining a light level associated with a liquid crystal display, the determined light level accounting for at least one of a backlight level or an ambient light level; enhancing an image to be displayed on the liquid crystal display, the image comprising a plurality of pixels having pixel values, including, for respective pixels of at least some of the plurality of pixels: determining a modified gamma value parameter, wherein the modified gamma value parameter depends on a ratio set in accordance with γ LCD /γ adjustment , wherein γ LCD is a gamma setting for the liquid crystal display, and wherein γ adjustment is a gamma adjustment based at least in part on a gamma offset value determined as a function of at least one of the ambient light level or the backlight level; and remapping a pixel value of the pixel from an initial value of the pixel to a remapped value in accordance with an equation that raises the initial value to the exponent of the modified gamma value parameter; and outputting the enhanced image for display on the liquid crystal display.
