Abstract
An electronic device may include an electronic display and image processing circuitry. The image processing circuitry may receive input image data in a non-linear color space at a bit-depth, truncate one or more least-significant-digits of the input image data, generating truncated image data, and determine an alpha value indicative of how many pixel locations, of a block of pixels, to which an increase in gray level is to be applied based on an input pixel value, corresponding to a pixel of interest within the block of pixels. Additionally, the alpha value may correspond to a ratio of gray levels in a linear color space that equates to a luminance level of the input pixel value at the bit-depth. The increase in the gray level may be applied to pixel values of the truncated image data corresponding to the pixel locations to generate dithered image data.
