Abstract

Systems and methods for perceptually synchronizing at least one secondary display that is in a same visual environment as a primary display. The image appearance parameters may be derived from the image/video shown on the primary display can be used to map the appearance of any arbitrary content on a secondary device. To produce a visually pleasing environment for a viewer in the visual environment, systems and methods are herein disclosed for synchronizing the display settings or parameters. The synchronization may be affected by dynamically adjusting the image data rendered upon one of the primary and/or secondary displays. Such dynamic adjustments may be made in accordance with the characteristics of the primary display and/or secondary display. Such adjustments may be made to the dynamic range, color mapping, etc. of the rendering on either display.

First claim

The invention claimed is:

1. A method for perceptually synchronizing a secondary display with a primary display, said secondary display and said primary display within a same visual environment and such that said secondary display rendering image data at substantially the same time as said primary display, the steps of said method comprising: establishing communications with said primary display, said primary display including a processor operative to adjust luminance settings of said primary display and to render image data on said primary display; establishing communications with said secondary display, said secondary display including a processor operative to adjust luminance settings of said secondary display and to render image data on said secondary display; receiving metadata from said primary display and said secondary display, said metadata identifying one or more capabilities of said primary display and identifying one or more capabilities of said secondary display, respectively; dynamically calculating an adjustment of luminance settings for at least one of said primary display and said secondary display based on at least one of said capabilities of said primary display and said capabilities of said secondary display indicated by said metadata; providing said adjustment of luminance settings calculated for said at least one of said primary display and said secondary display to said processor of said at least one of said primary display and said secondary display; and dynamically adjusting said luminance settings of said at least one of said primary display and said secondary display at said at least one of said primary display and said secondary display using said processor of said at least one of said primary display and said secondary display, said processor being configured to dynamically adjust said luminance settings based on said adjustment of luminance settings calculated for said at least one of said primary display and said secondary display, said luminance settings being separate from image data displayed by said at least one of said primary display and said secondary display wherein said adjustment of luminance settings is based at least in part on input from a light sensor.

2. The method of claim 1 , further comprising, if said adjustment of luminance settings is not substantially a good fit for rendering, approximating a best rendering settings for said at least one of said primary display and said secondary display.

3. The method of claim 2 , further comprising communicating said approximate best rendering settings as said adjustment of luminance settings to said at least one of said primary display and said secondary display.

4. The method of claim 1 , wherein said image data includes at least one of high dynamic range (HDR) image/video data, extended dynamic range (EDR) image/video data, visual dynamic range (VDR) image/video data and low dynamic range (LDR) image/video data.

5. The method of claim 1 , wherein the steps of establishing communications with said primary display and establishing communications with said secondary display comprise establishing communications between said primary display and said secondary display.

6. The method of claim 1 , further comprising dynamically adjusting color gamut settings of at least one of said primary display and said secondary display.

7. A system for perceptually synchronizing a secondary display with a primary display, said secondary display and said primary display within a same visual environment and such that said secondary display is rendering image data substantially at the same time as said primary display, said system comprising: computer readable storage for storing computer readable instructions; and a processor configured to execute said computer readable instructions; and wherein said primary display includes a processor operative to adjust luminance settings of said primary display and to render image data on said primary display; said secondary display includes a processor operative to adjust luminance settings of said secondary display and to render image data on said secondary display; said computer readable instructions comprise a display management module, said display management module capable of receiving metadata identifying one or more capabilities of said primary display and metadata identifying one or more capabilities of said secondary display; said display management module is capable of dynamically calculating an adjustment of luminance settings for at least one of said primary display and said secondary display based on at least one of said capabilities of said primary display and said capabilities of said secondary display indicated by said metadata; and said display management module is further capable of providing said adjustment of luminance settings calculated for said at least one of said primary display and said secondary display to said processor of said at least one of said primary display and said secondary display to facilitate dynamically adjusting the luminance settings of said at least one of said primary display and said secondary display at said at least one of said primary display and said secondary display using said processor of said at least one of said primary display and said secondary display, said processor being configured to dynamically adjust said luminance settings based on said adjustment of luminance settings calculated for said at least one of said primary display and said secondary display, said luminance settings being separate from image data displayed by said at least one of said primary display and said secondary display; wherein said adjustment of luminance settings is based at least in part on input from a light sensor.

8. The system of claim 7 , wherein said display management module resides in said primary display.

9. The system of claim 7 , wherein said display management module resides in said secondary display.

10. The system of claim 7 , wherein said display management module resides in a set top box, a game console, a computer, an audio-video receiver (AVR), a video processor, or a BluRay player.

11. The system of claim 7 , wherein said display management module is capable of approximating a best rendering settings for said at least one of said primary display and said secondary display, if said adjustment of luminance settings is not substantially a good fit for rendering.

12. The system of claim 7 , wherein said display management module is further capable of dynamically adjusting color gamut settings of at least one of said primary display and said secondary display.

13. The method of claim 1 , wherein said step of dynamically adjusting the luminance settings of said at least one of said primary display and said secondary display includes dynamically adjusting at least one of the minimum luminance and maximum luminance settings of said at least one of said primary display and said secondary display.

14. The method of claim 1 , wherein said steps of dynamically calculating said adjustment of luminance settings for said at least one of said primary display and said secondary display and dynamically adjusting the luminance settings of said at least one of said primary display and said secondary display occur on a scene-by-scene basis.

15. The method of claim 1 , wherein said step of dynamically adjusting the luminance settings of said at least one of said primary display and said secondary display comprises dynamically adjusting the luminance settings of said primary display.

16. The method of claim 1 , wherein said step of dynamically adjusting the luminance settings of said at lea
