MULTI-LEVEL STOCHASTIC DITHERING WITH NOISE MITIGATION VIA SEQUENTIAL TEMPLATE AVERAGING
First Claim
Patent Images
1. A method of displaying a first image on a display, the method comprising:
- generating a first version of the first image according to a first spatial dither template;
generating a second version of the first image according to a second spatial dither template, the second template being different from the first template; and
displaying the first image by successively displaying the first and second versions of the first image on the display.

Abstract
Displays, and methods of displaying images with the displays, which have quantized display characteristics for each of the pixels are disclosed. The displays and methods relate to both spatially and temporally dithering images so that the effective resolution of the display is higher than the result of the native spatial and intensity resolutions of the display, defined by pixel size, pitch, and number of quantization levels of each of the pixels.

-
generating a first version of the first image according to a first template; generating a second version of the first image according to a second template, the second template being different from the first template; and displaying the first and second versions of the first image such that an effective resolution of the first image is higher than the native intensity resolution of the display. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
