detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Embodiment 1

FIG. 1 is a method for adjusting power consumption according to an embodiment of the present invention, which is specifically as follows:

Step 101: When the pixel data in the frame buffer is updated, determining a low power consumption color value corresponding to the color value of the pixel data according to the color mapping information table, and replacing the color value of the pixel data in the frame buffer with The low power color value.

Step 102: Display according to the replaced pixel data in the frame buffer.

Here, the pixel data is data information buffered in a frame buffer in the prior art, and may be The method includes: a plurality of pixel points corresponding to the resolution of each frame of the system, and a color value corresponding to each pixel point. For example, if the resolution is 800×600, the pixel data includes 800×600 pixels, and each pixel corresponds to The color value.

The color mapping information table includes: an original color value, and a low power consumption color value corresponding to the original color value; wherein the low power color value, that is, the brightness value in the color value is lower than the original color value The color value of the value. The specified value may be a value preset according to actual conditions.

Here, it can be understood that the pixel data in the frame buffer in the prior art adopts the HSL color mode, that is, the hue (H), saturation (S), and lightness (L) modes; in this mode, the frame buffer is displayed. In the case of pixel data, the lower the brightness value of the color, the lower the power consumption. Therefore, by replacing the color value with a color value with a low luminance value, the display power consumption value is lowered.

Preferably, the system may save one or more color mapping information tables, where each color mapping information table corresponds to an application, wherein the application may be a game, or a web application;

The color mapping information table may include: four information fields;

The first information field is the identification information, and is used to identify the application corresponding to the color mapping information table, and may include the identifier of the application, that is, the configuration information of the application to which the color mapping information table belongs. The identifier can be the name of the application;

The second information field is one or more original color values;

The third information field is a low power color value corresponding to the original color value; the low power color value may be selected by the user or selected by the system;

Correspondingly, before determining the low power consumption color value corresponding to the color value of the pixel data according to the color mapping information table, the method may include: determining an application corresponding to the frame buffer, and selecting a color mapping according to the identifier of the application Information Sheet.

The application corresponding to the determined frame buffer is prior art, such as directly determined by the currently running application recorded by the CPU.

Preferably, the determining, according to the color mapping information table, a low power consumption color value corresponding to a color value of the pixel data, and replacing a color value of the pixel data in the frame buffer with the low power consumption color value, Can include:

Extract color values from pixel data,

Determining the extracted color value as an original color value, and determining a low power consumption color value corresponding to the original color value according to the color mapping information table;

The extracted color value is replaced with the low power color value; and so on, until all color values in the pixel data are replaced with the low power color value.

The extracted pixel data may be extracted from the beginning of the queue according to the pixel data; wherein the order of the queues of the pixel data is prior art, and details are not described herein.

Preferably, before performing step 101, the method further includes: setting the color mapping information table; or, when any one of the applications is initialized, setting a color mapping information table corresponding to the application.

The storing the color mapping information table corresponding to the application when the application is initialized is specifically: when any one of the applications is initialized, displaying a setting interface of the color mapping information table corresponding to the application, receiving and Save the color mapping information table after the setting is completed;

For example, when the game is initialized, the system displays the setting interface of the color mapping information table corresponding to the application to the user, and after the user sets and confirms, the color mapping information table corresponding to the application is established. Similarly, the user can reconfigure the mapping database by selecting the appropriate mapping color from the alternative low-power color groups according to his own aesthetic preferences, that is, autonomously setting a corresponding low-power to the high-power color values in the mapping database. Consume color to build a new mapping database.

Preferably, when the application is initialized, setting the color mapping information table corresponding to the application may further include: determining whether the application needs to perform conversion of a pixel color value, and setting a color mapping information table corresponding to the application when needed. Otherwise, the application is not set, and correspondingly, the color value is not converted when the application is running.

The determining whether the application needs to perform the conversion of the pixel color value may be: performing conversion of the pixel color value for the predetermined type of application; or performing pixel color conversion on the predetermined type of application; To determine if the application needs to convert pixel color values.

In this way, the user experience of the application runtime can be guaranteed. For example, when the movie is played, the user does not want to convert the color value, but wants to ensure the visual experience, then, the user can choose not to perform the color value conversion operation on the application such as the player. .

In the embodiment of the present invention, the color value is calculated according to the data of the three primary colors R, G, and B, and the values of R, G, and B are finely adjusted in the range of low power consumption to obtain the high, middle, and low The similar color values of the power consumption levels are used as the low power alternative color, and the medium color is the mapped color value by default.

It can be seen that, through the above solution, the color value of the pixel data in the frame buffer can be converted into a low-power color value according to the color mapping information table, so that the operation of the electronic device can be reduced without ensuring influence on the operation of the application. Power consumption, enhance the endurance of electronic devices, and ensure the user experience.

The monitoring module is specifically configured to notify the execution module to perform pixel color optimization when the application updates the corresponding pixel data to the frame buffer when the UI of any one of the applications changes.

The color information configuration module 25 can provide an interface for the user to use. For example, when the game is initialized, the system displays the default color configuration information of the current mapping database to the user, and after the user confirms, constructs a mapping database.
