Abstract

A method of displaying an image on a color display comprises receiving image data to be displayed, forming a first sub image and a second sub image from said image data, said first sub image comprising a first set of colors and said second sub image comprising a second set of colors, wherein said first set of colors and said second set of colors are disjoint sets, and wherein said first set of colors and said second set of colors comprise a metamer formed by at least a first color in said first set of colors and at least a second color in said second set of colors, and displaying said image using said first sub image and said second sub image, or a representation thereof, on a color display.

Claims

1. A method of displaying an image on a color display, the method comprising:

receiving image data to be displayed,

forming a first sub image and a second sub image from said image data, said first sub image comprising a first set of colors (R, G, B) and said second sub image comprising a second set of colors (R, B, Y), wherein said first set of colors and said second set of colors are disjoint sets, and wherein said first set of colors and said second set of colors comprise a metamer formed by at least a first color in said first set of colors and at least a second color in said second set of colors, and

displaying said image using said first sub image and said second sub image, or a representation thereof, on a color display.

2. A method according to claim 1, wherein the color sensation provided by the metamer is perceived as an essentially white color.

3. A method according to claim 1, wherein said first sub image and said second sub image are displayed simultaneously during a time period.

4. A method according to claim 3, additionally comprising:

forming a representation of said first sub image and said second sub image by averaging data associated with any colors which are included in both said first set of colors and said second set of colors.

5. A method according to claim 1, wherein said first sub image and said second sub image are displayed sequentially in time during a time period.

6. A method according to claim 3, wherein the time period is short enough to be perceived as a single frame.

7. A method according to claim 5, said time period being equal to or shorter than 20 milliseconds.

8. A method according to claim 5, said time period being equal to or shorter than 10 milliseconds.

9. A method according to claim 1, wherein the first set of colors comprises red, green and blue.

10. A method according to claim 1, wherein the second set of colors comprises blue and yellow.

11. A display controller characterized in that said display controller is arranged to perform the method according to claim 1.

12. A display comprising a display controller according to claim 11.

13. A display according to claim 12, wherein said display is one of a liquid crystal (LCD) display, a cathode ray tube (CRT) display with non overlapping electron beams, a flat intelligent tube (FIT) display, a plasma display panel (PDP), a polylight emitting diode (PolyLED) display, an organic light emitting diode (OLED) display and a field emission display (FED).
