Methods and apparatus for reduced low-tone half-tone pattern visibility

An apparatus for rendering at least a portion of a half-tone image on a display, comprising:

• a processor;
• a memory operably connected to the processor, the memory configured to store:
• an image receiver module, configured to receive an input image including a plurality of input pixels,
• a dithering module, configured to dither at least a portion of the input pixels,
• a pixel crush module, configured to set half-tone image pixels corresponding to the portion of the input pixels that are below a crush threshold to a crushed value, and
• an output module, configured to output the half-tone image pixels to an output device.

An apparatus for rendering at least a portion of a half-tone image on a display, comprising:

• means for receiving an input image including a plurality of input pixels;
• means for dithering at least a portion of the input pixels;
• means for setting half-tone image pixels corresponding to the portion of the input pixels that are below a crush threshold to a crushed value;
• and
• means for outputting the half-tone image pixels to an output device.

A non-transitory, computer readable medium comprising instructions that when executed causes one or more processors to perform a method of rendering at least a portion of a half-tone image on a display, the method comprising:

• receiving an input image including a plurality of input pixels;
• dithering at least a portion of the input pixels;
• setting half-tone image pixels corresponding to the portion of the input pixels that are below a crush threshold to a crushed value;
• and
• outputting the half-tone image pixels to an output device.
