FIELD SEQUENTIAL COLOR ENCODING FOR DISPLAYS

摘要

The optical performance is enhanced of display systems that use field sequential color and pulse width modulation to generate color and color gray scale values. Such enhancement may be achieved by various data encoding methods disclosed herein that may include temporal redistribution of bit values to mitigate color motional artifacts associated with field sequential color-based display systems, selective combination of intensity modulation, pulse width modulation, and/or the noncontiguous sequencing of primary colors. There is further an intelligent real-time dynamic manipulation of gray scale values in portions of an image that are computationally determined to be images of objects moving against a global background, so as to temporally front load or concentrate the bits comprising such moving objects and thereby further mitigate said motional artifacts using both actual and virtual aggregate pulse truncation across all primary colors being modulated.

1. A method comprising:
displaying a video image using field sequential color encoded in a plurality of video frames; receiving the plurality of video frames for displaying a foreground object and a background image in the video image; determining in the received plurality of video frames that the foreground object of a video image of at least one of the video frames is in motion relative to the background image of the video image; modifying a gray scale of the at least one of the video frames associated with the foreground object that is in motion relative to the background image of the video image to reduce the number of gray scales defining the foreground object; encoding the plurality of video frames including the modified video frame for image generation; and displaying the encoded plurality of video frames, including the modified video frame; wherein the plurality of video frames are displayed by temporally segregating primary color components of the video images by presenting each frame of video information by rapid consecutive generation of each primary component.
