MOTION COMPENSATED VIDEO HALFTONING

摘要

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for halftoning video images for presentation on an electronic display. In one aspect, input frames of video data may be received, where each input frame includes a number of input pixels, each input pixel having a respective first spatial coordinate location. For each input pixel, an output pixel is generated using a selected halftone value. The selected halftone value is substantially identical to a halftone value of a corresponding pixel in a comparison frame, where a spatial coordinate location of the “corresponding pixel” is determined based on a motion vector of an image element with which the pixel is associated.

1. An apparatus comprising:
an electronic display; and a display control module, the display control module configured to:
receive a plurality of input frames of video data, each input frame including a plurality of input pixels that depicts one or more image elements, each image element characterized by a respective motion vector, each input pixel having a respective first spatial coordinate location;for each input frame, render an output frame on the electronic display so as to form a displayed halftone image, the output frame including a plurality of output pixels, each output pixel being generated from a respective input pixel using a respective halftone value, each respective halftone value is substantially identical to a halftone value of a corresponding pixel in a comparison frame, wherein:
for a first portion of the input frame that includes a first subset of input pixels that includes only input pixels associated with image elements having a motion vector of zero, and a second subset of the input pixels that includes only input pixels associated with image elements having a non-zero motion vector;for each input pixel in the first subset of input pixels, the corresponding pixel in the comparison frame has a respective second spatial coordinate location identical to the respective first spatial coordinate location; andfor each input pixel in the second subset of input pixels, the corresponding pixel in the comparison frame has a respective third spatial coordinate location offset from the respective first spatial coordinate location, the spatial coordinate location offset being determined by the non-zero motion vector.
