Abstract

Aspects of the present invention relate to providing see-through computer display optics and reduction of color breakup in presented content.

Claims

1. A method for reducing color breakup in a head-mounted display that provides color sequential displayed images with a number of pixels in each displayed image to a user at a frame rate, comprising:

a. selecting a predetermined threshold for a speed of movement of the head mounted display;

b. detecting a speed of movement of the head mounted display; and

c. wherein if the detected speed of movement is above the threshold, monochrome images are displayed instead of color sequential images.

2. The method of claim 1, wherein the monochrome images are comprised of image content from the color sequential displayed images.

3. The method of claim 2, wherein the monochrome images are grey scale or luma images.

4. The method of claim 2, wherein the brightness of the monochrome images are adjusted to match that of the color sequential images.

5. The method of claim 3, wherein the monochrome images are provided by illuminating the display simultaneously with all the color light sources.

6. The method of claim 3, wherein the monochrome images are provided by illuminating the display with at least one color selected from a multi-color lighting system adapted to illuminate a reflective display.
