<p>This disclosure provides methods, apparatus, and computer programs encoded on computer storage media for reduced low tone pattern visibility. In one aspect, the disclosed methods receive an input image including a plurality of pixels, quantize the plurality of pixels, set half-tone image pixels corresponding to the portion of the input pixels that are below a crush threshold to a crushed value, and diffuse the quantization error resulting from the quantizing to half-tone image pixels other than the portion. In some implementations, the half-tone image pixels are then output to an output device such as an electronic display.</p> |
