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 display device comprising:

a display screen;

a memory; and

a processor configured to;

obtain color profile data that is based on a standard display device that is external to the display device, the color profile data being for one or more color profiles stored in the memory, each color profile characterizing a desired color and intensity output of the display screen;

measure a set of display characteristics of the display screen at multiple instances over a given duration of time during which an output of the display screen changes; and

determine a color mapping to adjust the set of measured display characteristics to corresponding values provided by at least one of the one or more color profiles, including adjusting the color mapping after one or more instances in which the set of display characteristics are measured.

2. The display device of claim 1, wherein the color profile format is independent of color measuring hardware.

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

4. The display device of claim 1, wherein determining the color mapping comprises:

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

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

5. The display device of claim 1, wherein intensity output corresponds to tone response or a gamma curve of the display device.

6. The display device of claim 1, wherein determining the color mapping comprises (i) multiplying color information of the standard display device with an inverse of color information from native color properties of the display device, and (ii) adjusting light intensity from the native color properties of the display device to match light intensity of the standard display device.

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

obtaining, by the display device, color profile data that is based on a standard display device that is external to the display device, the color profile data being for one or more color profiles stored in a memory, each color profile characterizing a desired color and intensity output of the display screen;

measuring, by the display device, a set of display characteristics of the display screen at multiple instances over a given duration of time during which an output of the display screen changes; and

determining, by the display device, a color mapping to adjust the set of measured display characteristics to corresponding values provided by at least one of the one or more color profiles, including adjusting the color mapping after one or more instances in which the set of display characteristics are measured.

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

9. The method of claim 7, further comprising:

receiving, by the display device, image data;

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

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

10. The method of claim 7, wherein the color profile is independent of color measuring hardware.

11. The method of claim 7, wherein determining the color mapping comprises:

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

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

12. The method of claim 7, wherein intensity output corresponds to tone response or a gamma curve of the display device.

13. The method of claim 7, wherein determining the color mapping comprises (i) multiplying color information of the standard display device with an inverse of color information from the native color properties of the display device, and (ii) adjusting light intensity from the native color properties of the display device to match light intensity of the standard display device.
