Abstract

The embodiments of the present invention provide a color control method and communication apparatus, the color control method includes: acquiring color temperature information of ambient light; calculating a suitable color parameter based on the color temperature information; adjusting display of the communication apparatus according to the suitable color parameter. Through the embodiments of the present invention, the quality of display image can be improved to a higher degree. Furthermore, the communication apparatus can change WB of display dynamically and can provide a way to optimize color to ambient light condition automatically.

Claims (42)

1. A color control method, applied to a display of a communication apparatus, the color control method comprising:

acquiring color temperature information of ambient light;

calculating a color parameter based on the color temperature information;

controlling parameter information of the display to adjust intensity of color of the display and temperature setting of the color of the display of the communication apparatus according to the color parameter calculated;

wherein the color control method further comprising:

acquiring brightness information of ambient light,

calculating a brightness parameter for the intensity of color of the display based on the brightness information, and

wherein the display of the communication apparatus is adjusted according to the color parameter and the brightness parameter, and

wherein the acquiring of the brightness information of ambient light includes:

acquiring, by an ambient light sensor of the communication apparatus, the brightness information of ambient light.

2. The color control method according to claim 1 , wherein the acquiring of the color temperature information of ambient light includes:

acquiring, by a camera of the communication apparatus, the color temperature information of ambient light.

3. The color control method according to claim 2 , wherein the acquiring of the color temperature information of ambient light includes:

acquiring, by an Auto White Balance (AWB) function of the camera, the color temperature information of ambient light.

4. The color control method according to claim 2 , wherein the acquiring of the color temperature information of ambient light includes:

acquiring, by an Image Signal Processor (ISP) of the camera, the color temperature information of ambient light.

5. The color control method according to claim 1 , wherein the calculating of the color parameter based on the color temperature information comprises:

determining the color parameter by looking up a pre-defined table according to the color temperature information,

wherein the pre-defined table is configured to map color temperature information to corresponding color parameters.

6. The color control method according to claim 1 , wherein the acquiring of the brightness information of ambient light includes:

acquiring, by a camera of the communication apparatus, the brightness information of ambient light.

7. The color control method according to claim 6 , wherein the acquiring of the brightness information of ambient light includes:

acquiring, by an Auto Exposure (AE) function of the camera, the brightness information of ambient light.

8. The color control method according to claim 6 , wherein the acquiring of the brightness information of ambient light includes:

acquiring, by an Image Signal Processor (ISP) of the camera, the brightness information of ambient light.

9. A non-transitory computer-readable program, wherein when the program is executed in a communication apparatus, the program enables a computer to carry out the method as claimed in claim 1 in the communication apparatus.

10. A non-transitory storage medium in which a computer-readable program is stored, wherein the computer-readable program enables a computer to carry out the method as claimed in claim 1 in the communication apparatus.

11. A communication apparatus, the communication apparatus comprising:
