Abstract

Various embodiments of a panoramic display for a wireless device are described. In one embodiment, a wireless device may include a display comprising a plurality of display regions. The display regions may include a central display region and multiple lateral display regions arranged to provide a panoramic display. Image compression and/or scaling may be applied to media content that is to be displayed in one or more of the lateral display regions based on the proximity of the lateral display region to the edge of the display.

Claims

1. A wireless device, comprising:

a panoramic display having a first aspect ratio, said panoramic display comprising a plurality of display regions including a central display region and a plurality of lateral display regions,

said wireless device to receive media source content having a second aspect ratio that differs from said first aspect ratio, said wireless device to compress said media source content to be displayed in one or more of said lateral display regions based on proximity of said one or more lateral display regions to an edge of said display.

2. The wireless device of claim 1, further comprising a frame buffer to store media content having said second aspect ratio.

3. The wireless device of claim 2, wherein said frame buffer comprises one or more overlay planes.

4. The wireless device of claim 1, further comprising a display controller to compress media content having said second aspect ratio.

5. The wireless device of claim 4, said display controller to apply image compression progressively for left lateral display regions and right lateral display regions.

6. The wireless device of claim 4, said display controller to apply image compression symmetrically for left lateral display regions and right lateral display regions.

7. The wireless device of claim 4, said display controller to apply image compression asymmetrically for left lateral display regions and right lateral display regions.

8. The wireless device of claim 4, said display controller to apply compression in at least one of a horizontal direction a vertical direction.

9. The wireless device of claim 4, said display controller to expand one or more of said display regions.

10. The wireless device of claim 4, said display controller to apply a compression ratio to a line of media source pixels to generate a compressed line of display pixels.

11. The wireless device of claim 4, said display controller comprising a plurality of hardware-based sample-rate converters.

12. The wireless device of claim 4, said display controller comprising a sample-rate converter software application.

13. A system for a wireless device, comprising:

a display controller to compress media source content stored by a wireless device, said wireless comprising a panoramic display having a first aspect ratio, said panoramic display comprising a plurality of display regions including a central display region and a plurality of lateral display regions, said media source content having a second aspect ratio that differs from said first aspect ratio,

said display controller to compress media source content to be displayed in one or more of said lateral display regions based on proximity of said one or more lateral display regions to an edge of said display.

14. The system of claim 13, said display controller comprising a plurality of hardware-based sample-rate converters.

15. The system of claim 13, said display controller comprising a sample-rate converter software application.

16. The system of claim 13, further comprising a frame buffer to store media content having said second aspect ratio.

17. A method comprising:

retrieving media source content stored by a wireless device, said wireless comprising a panoramic display having a first aspect ratio, said panoramic display comprising a plurality of display regions including a central display region and a plurality of lateral display regions, said media source content having a second aspect ratio that differs from said first aspect ratio; and

compressing media source content to be displayed in one or more of said lateral display regions based on proximity of said one or more lateral display regions to an edge of said display.

18. The method of claim 17, further comprising receiving said media source content at said wireless device.

19. The method of claim 17, further comprising displaying compressed media source content in one or more of said lateral display regions.
