Method, apparatus and system for providing color grading for displays

1. A system for processing picture data, comprising:

a picture source device for providing a plurality of picture data;

a display device including a display specification, the display specification including at least one display requirement; and wherein

the display device further comprising:

a memory configured to store a plurality of virtual device models, each of the virtual device models including at least one parameter for specifying at least one display feature of the display device;

a picture selector configured to select one of the stored virtual device models to control a display picture provided by the display device based on a comparison between the stored virtual device models and the display specification of the display device, and the picture selector is further configured to select one of the plurality of picture data based on the selected one of the stored virtual device models; and

a picture calibration component configured to adapt the selected one of the plurality of picture data selected by said picture selector to be provided by the same display device based on the selected one of the stored virtual device models.

2. The system as recited in claim 1 , wherein the at least one parameter specifies at least one of: display brightness, display color gamut, surround brightness, contrast ratio, color accuracy, color gamut, electrical-optical transfer function (gamma), average picture level dependent luminance transfer function, dithering level, picture size and viewing distance, motion behavior, and spatial resolution.

3. The system as recited in claim 1 , wherein the picture selector includes a decision matrix configured to score each display feature to each display requirement.

4. The system as recited in claim 3 , wherein the decision matrix includes weights to provide a level of importance for each display requirement.

5. The system as recited in claim 1 , wherein each of the plurality of virtual device models is configured to cover a plurality of display conditions.

6. The system as recited in claim 1 , further comprising a special virtual device model configured to cover a selected display to provide a given consistency on the display.

7. A method performed by a display device, comprising:

receiving, by the display device, virtual device models, each of the virtual device models corresponding to a different display class and including at least one parameter for specifying at least one display feature; said display class having different physical attributes such that picture data will appear differently on each of them;

comparing, by the display device, the virtual device models to display requirements for a particular display of the display device to select a best virtual device model based on a score; said score determined based on supported picture data information; and

rendering, by the display device, a display picture on the same particular display in accordance with the best virtual device model based on the comparing.

8. The method as recited in claim 7 , wherein the comparing includes generating a decision matrix to determine the score.

9. The method as recited in claim 8 , wherein the generating includes weighting features of the display requirements to provide a weighted score.

10. The method as recited in claim 7 , further comprising generating a plurality of virtual device models by calibrating a plurality of display types under a plurality of conditions.

11. The method as recited in claim 7 , further comprising generating the virtual device models to cover a plurality of display types and conditions.

12. The method as recited in claim 7 , further comprising generating one virtual device model to cover a plurality of display types and conditions.

13. The method as recited in claim 7 , further comprising generating a special virtual device model to cover a special display condition and provide a given effect on a display.

14. A display unit for processing a plurality of picture data, comprising:

a display including a display specification including at least one display requirement;

a picture selector for obtaining the plurality of picture data and operative to access a plurality of different virtual device models, each of the virtual device models including at least one parameter for specifying at least one display feature, and wherein the picture selector is configured to select one of the virtual device models to control a display picture provided by the display based on a comparison between the virtual device models and the display specification of the display, and the picture selector is further configured to select one of the plurality of the picture data based on the selected one of the virtual device models; and

a picture calibration component configured to adapt the selected one of the plurality of picture data selected by the picture selector to be displayed on the same display based on the selected virtual device model.

15. The display unit as recited in claim 14 , wherein the display specification includes requirements for at least one of: display brightness, display color gamut, surround brightness, contrast ratio, color accuracy, color gamut, electrical-optical transfer function (gamma), average picture level dependent luminance transfer function, dithering level, picture size and viewing distance, motion behavior, and spatial resolution.

16. The display unit as recited in claim 15 , wherein the picture selector includes a decision matrix configured to score each display feature of each virtual device model to each display requirement of the display.

17. The display unit as recited in claim 16 , wherein the decision matrix includes weights to provide a level of importance for each display requirement.

18. The display unit as recited in claim 14 , wherein each virtual device model is configured to cover a plurality of display types and conditions.
