SEE-THROUGH COMPUTER DISPLAY SYSTEMS
Aspects of the present invention relate to providing see-through computer display optics and reduction of color breakup in presented content.
1 . A method for reducing color breakup in a head-mounted display that provides full color images with a number of pixels to a user, wherein the full color images are comprised of color sequential displayed subframe images, comprising;
a. detecting a speed of movement of the head mounted display; and
b. digitally shifting the subframe images relative to each other by a number of pixels that corresponds to the detected speed of movement and in reverse direction so that the subframe images are aligned with each other within each full color image and color breakup is reduced.
2 . The method of claim 1 , wherein the step of detecting includes measuring the movement with an inertial movement sensor that is mounted proximate the head-mounted display.
3 . A method for reducing color breakup in a head-mounted display that provides full color images with a number of pixels to a user, wherein the full color images are comprised of color sequential displayed subframe images, 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. if the detected speed of movement is above the threshold, the number of pixels in the images is reduced with a simultaneous corresponding increase in frame rate that the subframes are displayed, while the subframe images are shifted relative to each other within each full color image so that the subframe images are aligned with each other and color breakup is reduced.
4 . The method of claim 3 , wherein the step of detecting includes measuring the movement with an inertial movement sensor that is mounted proximate the head-mounted display.
5 . A method for reducing color breakup in a head-mounted that provides full color images with a number of pixels to a user, wherein the full color images are comprised of color sequential displayed subframe images, and the head mounted display includes an eye camera, comprising;
a. detecting a speed of eye movement with the eye camera; and
b. digitally shifting the subframe images relative to each other by a number of pixels that corresponds to the detected speed of eye movement and in reverse direction so that the subframe images are aligned with each other within each full color image and color breakup is reduced.
6 . The method of claim 5 , wherein the eye camera captures eye images from an optical path that is in-line with an optical path for image light.
