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, the number of pixels in each displayed image is reduced with a simultaneous corresponding increase in frame rate to thereby reduce color breakup while maintaining a bandwidth associated with displaying the images.

2. (canceled)

3. (canceled)

4. 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, and the head-mounted display includes an eye camera, comprising:

a. selecting a predetermined threshold for a speed of eye;

b. detecting a speed of eye movement with the eye camera; and

c. wherein if the detected speed of eye movement is above the threshold, the number of pixels in each displayed image is reduced with a simultaneous corresponding increase in frame rate to thereby reduce color breakup while maintaining a bandwidth associated with displaying the images.

5. (canceled)

6. A method for reducing color breakup in a head-mounted display including an eye imaging camera and an inertial measurement unit, 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 eye;

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

c. detecting a speed of eye movement with the eye camera;

d. detecting a speed of movement of the head mounted display with the inertial measurement unit; and

e. wherein if the detected speed of eye movement or the detected speed of movement of the head mounted display are above their respective thresholds, the number of pixels in each displayed image is reduced with a simultaneous corresponding increase in frame rate to thereby reduce color breakup while maintaining a bandwidth associated with displaying the images.

7. The method of claim 6 further comprising:

wherein if the detected speed of eye movement or the detected speed of movement of the head mounted display are above their respective thresholds, the number of pixels in each displayed image is reduced with a simultaneous corresponding increase in frame rate, or digitally shifting the subframe images relative to each other by a number of pixels that corresponds to the detected difference in speed of movement and in reverse direction between the eye movement and the movement of the head mounted display so that the subframe images are aligned with each other within each full color image to thereby reduce color breakup while maintaining a bandwidth associated with displaying the images.
