Abstract

A method for controlling image display is provided. The method includes determining a target image display scheme based on at least one of a currently displayed image or a user operation, and processing and displaying a to-be-displayed image based on the target image display scheme. The target image display scheme may contain one or more parameters related to image display effects.

Claims

1. A method for controlling image display, comprising:

determining a first image display scheme based on property information of a currently displayed image and a relationship between image property information and image display schemes, and determining a power saving level corresponding to the first image display scheme based on a relationship between power saving levels and the image display schemes, when the currently displayed scene is different from a previously displayed scene;

determining a second image display scheme based on a type of a user operation and a relationship between types of user operation and the image display schemes, and determining a power saving level corresponding to the second image display scheme based on the relationship between the power saving levels and the image display schemes;

determining the first image display scheme to be a target image display scheme when the power saving level corresponding to the first image display scheme is higher than the power saving level corresponding to the second image display scheme, and determining the second image display scheme to be the target image display scheme when the power saving level corresponding to the second image display scheme is higher than the power saving level corresponding to the first image display scheme, the target image display scheme comprising at least one parameter related to image display effects; and

processing and displaying a to-be-displayed image based on the target image display scheme.

2. The method of claim 1, wherein the property information of the currently displayed image is selected from the group consisting of at least a color value and a transparency value.

3. The method of claim 1, wherein determining the target image display scheme comprises:

determining the target image display scheme every time after a preset period.

4. The method of claim 1, wherein the target image display scheme is preset based on fidelity optimized signal scaling technology.

8. The method of claim 1, wherein the target image display scheme is preset based on content adaptive brightness control technology.

5. A terminal, comprising:

a memory configured to store computer-readable program codes; and

a processor configured to invoke the computer-readable program codes to;

determine a first image display scheme based on property information of a currently displayed image and a relationship between image property information and image display schemes, and determining a power saving level corresponding to the first image display scheme based on a relationship between power saving levels and the image display schemes, when the currently displayed scene is different from a previously displayed scene;

determine a second image display scheme based on a type of a user operation and a relationship between types of user operation and the image display schemes, and determining a power saving level corresponding to the second image display scheme based on the relationship between the power saving levels and the image display schemes;

determine the first image display scheme to be a target image display scheme when the power saving level corresponding to the first image display scheme is higher than the power saving level corresponding to the second image display scheme, and determining the second image display scheme to be the target image display scheme when the power saving level corresponding to the second image display scheme is higher than the power saving level corresponding to the first image display scheme, the target image display scheme comprising at least one parameter related to image display effects; and

process and display a to-be-displayed image based on the target image display scheme.

6. The terminal of claim 5, wherein the property information of the currently displayed image is selected from the group consisting of at least a color value and a transparency value.

7. The terminal of claim 5, wherein the target image display scheme is preset based on fidelity optimized signal scaling technology.

9. A non-transitory computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to carry out actions:

determining a first image display scheme based on property information of a currently displayed image and a relationship between image property information and image display schemes, and determining a power saving level corresponding to the first image display scheme based on a relationship between power saving levels and the image display schemes, when the currently displayed scene is different from a previously displayed scene;

determining a second image display scheme based on a type of a user operation and a relationship between types of user operation and the image display schemes, and determining a power saving level corresponding to the second image display scheme based on the relationship between the power saving levels and the image display schemes;

determining the first image display scheme to be a target image display scheme when the power saving level corresponding to the first image display scheme is higher than the power saving level corresponding to the second image display scheme, and determining the second image display scheme to be the target image display scheme when the power saving level corresponding to the second image display scheme is higher than the power saving level corresponding to the first image display scheme, the target image display scheme comprising at least one parameter related to image display effects; and

processing and displaying a to-be-displayed image based on the target image display scheme.

10. The non-transitory computer-readable storage medium of claim 9, wherein the property information of the currently displayed image is selected from the group consisting of at least a color value and a transparency value.

11. The non-transitory computer-readable storage medium of claim 9, wherein the computer program executed by the processor to carry out the action of determining the target image display scheme is executed by the processor to carry out actions, comprising:

determining the target image display scheme every time after a preset period.

12. The non-transitory computer-readable storage medium of claim 9, wherein the target image display scheme is preset based on fidelity optimized signal scaling technology.
