Apparatus and method for setup frame sequencing in color sequential display systems
First Claim
1. A color sequential image display apparatus, comprising:
- (a) a display;
(b) an image generator for generating a fundamental image on said display, said fundamental image having a plurality of distinct color components, said plurality of color components having a display sequence characterized in that at least one of said color components is displayed out of time-phase with the remainder of said color components of said fundamental image;
(c) viewing means synchronized with said display for independently viewing each of said color components of said fundamental image sequentially during different display frames; and
(d) a color sequence controller which initiates the display of at least some of said color components prior to viewing such said color components through said viewing means, thereby reducing the effects of display frame crosstalk.

Abstract
A color sequential image display apparatus and method which reduces the effects of display frame crosstalk in the display apparatus by incorporating setup display frames for each color component in the color display sequence, where the display of each sequentially displayed color component is initiated and updated immediately prior to independently viewing the color component through synchronized color-filtering eyewear, thereby avoiding interference from previously viewed color components in the display sequence. The use of such setup frame sequencing has particular application in confidential viewing and three-dimensional viewing systems where sequential color encoding of the image signal is utilized.

- 13. In a color sequential image display apparatus having means for displaying and independently viewing each of a plurality of color components of a fundamental image sequentially over time through a synchronized color-filter viewing apparatus, the improvement comprising means for initiating the display of at least some of said color components prior to viewing such said color components through said viewing apparatus, thereby reducing the effects of display frame crosstalk.

16. A method for reducing display frame crosstalk in a color sequential image display apparatus, comprising the steps of:
-
(a) displaying a plurality of color components of a fundamental image sequentially over time on a display apparatus, wherein said plurality of color components have a display sequence characterized in that at least one of said color components is always displayed during a different display frame of said display apparatus than the remainder of said color components of said fundamental image;
(b) independently viewing each of said color components of said fundamental image sequentially over time during different display frames of said display apparatus in synchronization with said color component display sequence; and
(c) initiating the display of at least some of said color components of said fundamental image on said display prior to independently viewing such said color components. - View Dependent Claims (17, 18, 19, 20)
