Abstract

Disclosed embodiments relate to adjusting the color output of a display device. For example, a method for adjusting the color output of a display device based on a color profile may comprise receiving, by a display device, a color profile indicative of the native properties of a display device, generating, by the display device, a color mapping based on the received color profile, and storing, by the display device, the color mapping. The method may further comprise displaying, by the display device, an image based on the stored color mapping.

Claims

1. A computing system, comprising:

a display device 102 comprising;

a display screen 104;

a storage 118; and

a processor 106 configured to;

receive a color profile 120 characterizing the color properties of the display screen 104;

create a color mapping 122 between a color space and the display screen 104 based on the color profile 120;

store the color mapping 122 in the storage 118.

2. The computing system of claim 1, wherein the color profile 120 format is independent of color measuring hardware.

3. The computing of claim 1, wherein the color profile 120 comprises an International Color Consortium profile.

4. The computing system of claim 1, wherein the processor 106 is further configured to:

receive image data;

compare the image data to the stored color mapping 122; and

display an image on the display screen 104 based on the comparison.

5. The computing system of claim 1, wherein creating a color mapping 122 between a color space and the display screen 104 comprises:

determining information about the color properties of the display screen 104 based on the color profile 120; and

creating the color mapping 122 based on the determined information about the color properties of the display screen 104.

6. A method for adjusting the color output of a display device 104 based on a color profile 120, comprising:

receiving, by a display device 102, a color profile 120 indicative of the native color properties of a display device 102;

generating, by the display device 102, a color mapping 122 based on the received color profile 120;

storing, by the display device 102, the color mapping 122; and

displaying, by the display device 102, an image based on the stored color mapping 122.

7. The method of claim 6, wherein the color profile 120 comprises an International Color Consortium profile.

8. The method of claim 6, wherein displaying an image based on the stored color mapping 122 comprises:

receiving, by the display device 104, image data;

comparing, by the display device 104, the received image data to the stored color mapping 122; and

displaying, by the display device 104, the image data based on the comparison.

9. The method of claim 6, wherein the color profile 120 is independent of color measuring hardware.

10. The method of claim 6, wherein generating a color mapping 122 comprises:

extracting, by the display device 104, color information from the color profile 120; and

generating, by the display device 104, a color mapping 122 based on the extracted color information.

11. A machine-readable storage medium encoded with instructions executable by a display device, the machine-readable medium comprising instructions to:

receive formatted information 120 indicative of the color characteristics of a display device 104;

correlate input color information to color information for display based on the formatted information 120;

store the correlation 122; and

display an image based on the correlation 122.

12. The machine-readable storage medium of claim 11, wherein instructions for correlating the color characteristics of the display device 104 comprise instructions to:

convert the received formatted information 120 into information compatible with a color mapping method; and

perform the color mapping method using the converted information.

13. The machine-readable storage medium of claim 11, wherein the formatted information 120 may be created by multiple types of color measuring hardware.

14. The machine-readable storage medium claim 11, wherein the formatted information 120 comprises an International Color Consortium profile.

15. The machine-readable storage medium of claim 11, wherein instructions for displaying an image based on the correlation 122 comprise instructions to:

receive image data;

compare the received image data to the correlation 122; and

display the image data based on the comparison.
