Method for dynamically adjusting energy-saving grade of terminal, non-transitory computer-readable storage medium, and terminal

A terminal, comprising:

• a processor;
• and
• a memory coupled to the processor and storing computer programs thereon, which when executed by the processor, cause the processor to:
• acquire an application identifier of a currently displayed application;
• determine, by querying a preset first white list, a first energy-saving grade corresponding to the application according to the application identifier, and acquire display effect parameters corresponding to the first energy-saving grade, wherein the first white list defines an association relationship between a plurality of application identifiers and a plurality of energy-saving grades;
• set an energy-saving grade of the terminal according to the first energy-saving grade, and process a to-be-displayed image according to the display effect parameters corresponding to the first energy-saving grade;
• read a fidelity optimized signal scaling (FOSS) configuration file by calling a preset configuration file access interface when the energy-saving grade is a FOSS grade, and acquire the display effect parameters corresponding to a first FOSS grade according to the FOSS configuration file, wherein the FOSS configuration file stores a plurality of FOSS grades, a plurality of groups of display effect parameters, and a mapping list defining an association relationship between the energy-saving grades and the display effect parameters;
• and
• transmit the display effect parameters to an algorithm setting module, to cause a FOSS module to adjust color gradation of the to-be-displayed image according to the display effect parameters received in the algorithm setting module and display the adjusted to-be-displayed image.

A non-transitory computer-readable storage medium storing computer programs which, when executed by a processor, cause the processor to:

• acquire an application identifier of a currently displayed application;
• determine, by querying a preset first white list, a first energy-saving grade corresponding to the application according to the application identifier, wherein the first white list defines an association relationship between a plurality of application identifiers and a plurality of energy-saving grades;
• acquire display effect parameters corresponding to the first energy-saving grade;
• set an energy-saving grade of a terminal according to the first energy-saving grade, and process a to-be-displayed image according to the display effect parameters corresponding to the first energy-saving grade;
• query a preset second white list, and determining whether the application identifier belongs to the preset second white list, wherein the preset second white list comprises a plurality of application identifiers whose corresponding applications have rights to adjust their own energy-saving grades;
• in response to a determination that the application identifier belongs to the preset second white list, acquire screenshots of the application in a preset duration by performing, according to a second preset cycle, screen capture processing on the application;
• determine target screenshots by analyzing histograms of the screenshots, and determine a number of the target screenshots, wherein the target screenshots are the screenshots that satisfy a first preset condition, wherein the histogram of each target screenshots contains a plurality of target gray scales, wherein the number of pixels corresponding to each target gray scale exceeds a preset first quantity threshold, and the first preset condition is that the number of the target gray scales contained in the histogram of the target screenshot exceeds a preset second quantity threshold;
• and
• determine that a second preset condition of adjusting the energy-saving grade is satisfied when the number of target screenshots exceeds a preset third quantity threshold, and perform the action of determining the first energy-saving grade corresponding to the application according to the application identifier.
