Image processing method and electronic device

An electronic device, comprising a memory, a display screen,

• and one or more processors, wherein the memory, the display screen, and the processor are coupled;
• and the memory stores computer program code, the computer program code comprises computer instructions, and the computer instructions, when executed by the processor, cause the electronic device to perform a method of image processing, the method comprising:
• receiving a first operation performed by a user on a touch screen of the electronic device:
• starting a first application in response to the first operation:
• receiving a second operation performed by the user on the touch screen of the electronic device;
• and
• exiting the first application in response to the second operation,
• wherein in a process from starting of the first application to exiting of the first application, the electronic device performs drawing, rendering, and synthesis operations on a first image frame and a second image frame of the first application;
• and
• the performing drawing, rendering, and synthesis operations on a first image frame and a second image frame of the first application comprises:
• performing, by an application process, drawing and rendering on the first image frame in a drawing and rendering period of the first image frame, and storing the obtained first image frame into a free buffer object in a buffer queue:
• sending, by a synthesis thread when the synthesis thread performs no synthesis operation in a synthesis period of the first image frame, a first adjustment request to the application process;
• and
• increasing, by the application process based on the first adjustment request, a count of free buffer objects in the buffer queue, to cause the application process to draw and render the second image frame in a drawing and rendering period of the second image frame and then store the obtained second image frame into a free buffer object in the buffer queue, wherein the drawing and rendering period of the second image frame is later than the drawing and rendering period of the first image frame, a drawing start moment of the second image frame is different from a drawing start moment of the first image frame by N periods, and N is a positive integer.

A computer-readable storage medium, comprising computer instructions, wherein when the computer instructions are run on an electronic device, the electronic device is caused to perform a method of image processing, the method comprising:

• receiving a first operation performed by a user on a touch screen of the electronic device;
• starting a first application in response to the first operation:
• receiving a second operation performed by the user on the touch screen of the electronic device;
• and
• exiting the first application in response to the second operation,
• wherein in a process from starting of the first application to exiting of the first application, the electronic device performs drawing, rendering, and synthesis operations on a first image frame and a second image frame of the first application;
• and
• the performing drawing, rendering, and synthesis operations on a first image frame and a second image frame of the first application comprises:
• performing, by an application process, drawing and rendering on the first image frame in a drawing and rendering period of the first image frame, and storing the obtained first image frame into a free buffer object in a buffer queue:
• sending, by a synthesis thread when the synthesis thread performs no synthesis operation in a synthesis period of the first image frame, a first adjustment request to the application process;
• and
• increasing, by the application process based on the first adjustment request, a count of free buffer objects in the buffer queue, to cause the application process to draw and render the second image frame in a drawing and rendering period of the second image frame and then store the obtained second image frame into a free buffer object in the buffer queue, wherein the drawing and rendering period of the second image frame is later than the drawing and rendering period of the first image frame, a drawing start moment of the second image frame is different from a drawing start moment of the first image frame by N periods, and N is a positive integer.
