Problems solved by technology

Usually, this problem can be slightly mitigated, but not eliminated, by increasing the number of base color segments per frame, thereby minimizing the visibility of colors on the rising and falling edges of the target
However, most sequential display systems limit the number of primary color segments per frame

Embodiment Construction

[0011] figure 1 An example sequential color display system 10 is described that includes a light source 12 for producing a light beam 14 that is directed through a rotating color wheel 16 having at least three separate primary color windows 17, e.g., at least one red (R ), a green (G) and a blue (B) window. A typical color wheel according to the prior art has two red, two blue and two green windows interleaved in the RGBRGB sequence. During rotation of the color wheel 16 , red, green and blue light successively reaches the surface of the light modulator 18 for reflection therefrom to the display screen 20 .

[0012] Controller 22 controls the operation of light modulator 18 in response to an incoming television signal comprising a sequence of pictures, each of which occurs at a time according to the specified television format (i.e., 1 / 60 of a second for NTSC and 1 / 60 of a second for PAL). 50 seconds) among the frame intervals established. For each picture, controller 22 ge...

Abstract

To sequentially display pictures in a television signal, a first picture is separated into sets of red, green and blue segments, with each segment of each color interleaved with the segments of the other colors in a first sequence for display in that sequence. Each successive picture is likewise separated into sets of red, green and blue segments, which each segment of each color interleaved with the segments of the other colors in a shifted sequence for display in that sequence. Shifting the color sequence of the segments of each successive picture among the primary colors so at least the first and last segment of the occurrence of motion artifacts that manifest themselves as a color distortion at the leading and trailing edges of a moving object followed by a viewer's eye.

Description

[0001] This application claims the benefit under 35 U.S.C. 119(e) of U.S. Provisional Patent Application No. 60 / 427,859, filed November 20, 2002, which is hereby incorporated by reference. technical field [0002] The present invention relates to a technique for reducing motion artifacts of a manifest itself in a sequential display system. Background technique [0003] Today's sequential display systems typically include a light source that illuminates a light modulator that controls the illumination of each of the multiple picture elements (pixels) projected onto the display. The controller controls the light modulator in response to the input potential signal so that the light modulator displays successive pictures in the television signal, each picture occurring during a corresponding picture interval. The length of the picture interval depends on the selected TV system. The NTSC system currently used in the United States specifies a picture interval of 1 / 60 second, whil...
