Stereoscopic field sequential colour display control
View Patent ↗The present invention relates to a method, an apparatus, a method and a computer program suitable for controlling a stereoscopic field sequential color display to provide a first primary color component image for a user's first eye and a second primary color component image for the user's second eye, wherein the first and the second primary color component images are both provided either at least partially overlapping in time or alternately in uninterrupted succession and wherein the primary color components of the first and second primary color component images are different from each other.
1. A method comprising:
providing to a stereoscopic field sequential color display a sequence of pairs of first and second primary color component images, said first primary color component images being for a first eye of a user of said stereoscopic field sequential color display and said second primary color component images being for a second eye of said user of said stereoscopic field sequential color display, said pairs of said first and second primary color component images being provided such that one of the first and second primary color component images in at least one pair completely overlaps the other in time in a stereoscopic video stream for said stereoscopic field sequential color display,
wherein the first and second primary color component images in said pairs are each composed of only one primary color, and
wherein, within a sequence of said pairs of said first and second primary color component images, the first and second primary color component images have a different color from one another for at least a portion of the sequence.
2. The method according to claim 1 , wherein the primary colors of the first and second primary color component images form part of a set of three primary color components.
3. The method according to claim 1 , wherein a color composed of the first and the second primary color component images is substantially a neutral color.
4. The method according to claim 1 , wherein the first and second primary color component images comprise complementary colors.
5. The method according to claim 1 , wherein the first and second primary color component images are provided asynchronously.
6. The method according to claim 1 , wherein the first and second primary color component images are provided synchronously.
7. The method according to claim 1 , wherein the first and second primary color component images are displayed for periods of unequal duration.
8. The method according to claim 1 , wherein during a time period there is no primary color component image displayed.
9. The method according to claim 1 , wherein within a sequence of first and second primary color component image pairs, the first and second primary color component images have the same color.
10. An apparatus comprising:
one or more processors; and
one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the apparatus to perform the following:
provide to a stereoscopic field sequential color display a sequence of pairs of first and second primary color component images, said first primary color component images being for a first eye of a user of said stereoscopic field sequential color display and said second primary color component images being for a second eye of said user of said stereoscopic field sequential color display, said pairs of said first and second primary color component images being provided such that one of the first and second primary color component images in at least one pair completely overlaps the other in time in a stereoscopic video stream for said stereoscopic field sequential color display,
wherein the first and second primary color component images in said pairs are each composed of only one primary color, and
wherein, within a sequence of said pairs of said first and second primary color component images, the first and second primary color component images have a different color from one another for at least a portion of the sequence.
11. The apparatus according to claim 10 , further comprising the stereoscopic field sequential color display.
12. The apparatus according to claim 11 , further comprising a stereoscopic camera.
13. The apparatus according to claim 11 , wherein the stereoscopic field sequential color display comprises at least one of a color wheel and backlight source.
14. The apparatus according to claim 11 , wherein the stereoscopic field sequential color display is an autostereoscopic display.
15. The apparatus according to claim 11 , wherein the stereoscopic field sequential color display comprises one of a parallax barrier, lenticular lens, bidirectional backlight source, a holographic screen and two separate display units.
16. The apparatus according to claim 11 , wherein the stereoscopic field sequential color display is one of a projection-based display and a direct-view display.
17. The apparatus according to claim 10 , forming part of a mobile device.
