Image processing method, electronic device, readable medium and program product

By adjusting the Vsync signals of multiple applications in the terminal device, applications with lower rendering frame rates are synchronized with applications with the highest rendering frame rates, and the increase in power consumption caused by the out-of-synchronization of the Vsync signal is solved, achieving more efficient image synthesis and a smoother visual experience.

AI Technical Summary

Technical Problem

In the terminal device, since the Vsync signal is not synchronized during the layer rendering and synthesis of multiple applications, the frequency of the image synthesis module synthesizes image frames increases, thereby increasing the power consumption of the terminal device.

Method used

By adjusting the Vsync signals of multiple applications, the Vsync signals of applications with lower rendering frame rates are aligned with the Vsync signals of applications with highest rendering frame rates, reducing the number of synthesis times of the image synthesis module, and reducing the synthesis frame rate and power consumption.

Benefits of technology

It effectively reduces the number of synthesis times and power consumption of the image synthesis module, while maintaining a smooth and clear visual experience brought by high rendering frame rates, especially in high-speed dynamic picture scenes to reduce the phenomenon of drag and blur.

Abstract

The present application relates to the field of smart terminal technology, and discloses an image processing method, an electronic device, a readable medium, and a program product. In the case where the image frame to be generated includes the display content of multiple applications, the image processing method of the present application can determine the first application with the largest rendering frame rate among the multiple applications, and adjust the Vsync‑app signals of the other applications except the first application in the multiple applications to be synchronized with the Vsync‑app signal of the first application. Then, the terminal device can draw, render, and synthesize image frames based on the adjusted Vsync‑app signal. Thus, even if at least two applications among the multiple applications of the terminal device update the rendering content, the image synthesis module only needs to perform image synthesis once, which reduces the number of synthesis times of the image synthesis module, reduces the synthesis frame rate, and greatly reduces power consumption.
