Abstract

An autostereoscopic system is provided. The autostereoscopic system comprises a video source configured to provide video content in a video source format and a monitor system coupled to the video source and configured to receive the video content in the video source format. The monitor system comprises an interdigitation module configured to receive the video content in the video source format and interdigitate the video content in the video source format into an autostereoscopic image, a video rendering module coupled to the interdigitation module configured to receive the autostereoscopic image from the interdigitated module and provide a rendered autostereoscopic image, a display coupled to the video rendering module and configured to receive the rendered autostereoscopic image, and a lenticular screen held in juxtaposition with the display. Temperature compensation may be employed within the system.

Claims

1. In an autostereoscopic system wherein video content is provided in a video source format to a video display having a lenticular screen arranged in juxtaposition with the display, an improvement comprising an interdigitation module incorporated as part of an electronics module associated with the video display, wherein the interdigitation module receives the video content in the video source format and maps the video content in the video source format into multiple perspectives of an autostereoscopic image.

2. The autostereoscopic system of claim 1, wherein the video source format comprises one from a group comprising:

n-tile format;

stereo pair; and

planar view plus depth map.

3. The autostereoscopic system of claim 2, wherein the video content is in one from a group comprising NTSC, PAL, and high definition format.

4. The autostereoscopic system of claim 1, wherein the video content in the video source format is scaled before receipt by the interdigitation module.

5. The autostereoscopic system of claim 1, wherein the interdigitation module is configured to compensate for temperature changes to the video display and a lenticular screen placed in juxtaposition with the video display.

6. The autostereoscopic system of claim 5, wherein the interdigitation module compensates for temperature changes by altering selected pixel positions such that a central viewing zone in front of the lenticular screen provides good viewing characteristics for the temperature change anticipated.

7. An autostereoscopic system, comprising:

a video source configured to provide video content in a video source format; and

a monitor system coupled to the video source and configured to receive the video content in the video source format, the monitor system comprising;

an interdigitation module configured to receive the video content in the video source format and interdigitate the video content in the video source format into an autostereoscopic image;

a video rendering module coupled to the interdigitation module configured to receive the autostereoscopic image from the interdigitated module and provide a rendered autostereoscopic image;

a display coupled to the video rendering module and configured to receive the rendered autostereoscopic image; and

a lenticular screen held in juxtaposition with the display.

8. The autostereoscopic system of claim 7, wherein the video source format comprises one from a group comprising:

n-tile format;

stereo pair; and

planar view plus depth map.

9. The autostereoscopic system of claim 8, wherein the video content is in one from a group comprising NTSC, PAL, and high definition format.

10. The autostereoscopic of claim 7, wherein the video content in the video source format is scaled before receipt by the interdigitation module.

11. The autostereoscopic system of claim 7, wherein the interdigitation module is configured to compensate for temperature changes to the video display and the lenticular screen placed in juxtaposition with the video display.

12. The autostereoscopic system of claim 11, wherein the interdigitation module compensates for temperature changes by altering selected pixel positions such that a central viewing zone in front of the lenticular screen provides good viewing characteristics for the temperature change anticipated.

13. The autostereoscopic system of claim 7, wherein the monitor system further comprises a monitor housing comprising the interdigitation module, the video rendering module, and the display.

14. The autostereoscopic system of claim 7, wherein the monitor system further comprises a monitor housing comprising the video rendering module and the display, and the interdigitation module comprises a separate interdigitation device located external to the monitor housing.

15. An autostereoscopic display system, comprising:

an interdigitation module configured to receive the video content in the video source format and interdigitate the video content in the video source format into an autostereoscopic image;

a video rendering module coupled to the interdigitation module configured to receive the autostereoscopic image from the interdigitated module and provide a rendered autostereoscopic image;

a display coupled to the video rendering module and configured to receive the rendered autostereoscopic image; and

a lenticular screen held in juxtaposition with the display.

16. The autostereoscopic display system of claim 15, wherein the video source format comprises one from a group comprising:

n-tile format;

stereo pair; and

planar view plus depth map.

17. The autostereoscopic display system of claim 15, wherein the video content is in one from a group comprising NTSC, PAL, and high definition format.

18. The autostereoscopic display system of claim 17, wherein the video content in the video source format is scaled before receipt by the interdigitation module.

19. The autostereoscopic display system of claim 15, wherein the interdigitation module is configured to compensate for temperature changes to the video display and the lenticular screen placed in juxtaposition with the video display.

20. The autostereoscopic display system of claim 15, wherein the interdigitation module compensates for temperature changes by altering selected pixel positions such that a central viewing zone in front of the lenticular screen provides good viewing characteristics for the temperature change anticipated.
