Problems solved by technology

However, due to chip performance issues and resource competition issues during multitasking, sometimes there is a situation where a frame of image cannot be processed within 16.7 milliseconds. At this time, the processing chip will send the previous frame of image to the screen for display again, that is, Repeatedly display the previous frame of image, then the user will obviously feel the lagging phenomenon
However, there is no effective solution to this kind of stuck problem.

Embodiment 1

[0041] A method to improve image fluency, such as image 3 As shown, can include:

[0042] Step 301, when the vertical synchronization signal VSync sent by the display arrives, start the processing of the current frame data;

[0043] Step 302, during the process of processing the current frame data, detect in real time whether the processing of the current frame data can be completed in the VSync cycle;

[0044] Step 303, when it is determined that the processing of the current frame data cannot be completed within the VSync period, delay the VSync period by a predetermined time length.

[0045] In practical applications, in order to synchronize the display process of the display with the video controller of the electronic device system, after one frame of image drawing is completed and before the next frame is ready to be drawn, the display will send a vertical synchronization signal (vertical synchronization, VSync). Displays are usually refreshed at a fixed frequency, and...

Embodiment 2

[0053] A device for improving image fluency, such as Figure 5 As shown, can include:

[0054] The trigger module 51 is used to start the processing of the current frame data when the vertical synchronization signal VSync sent by the display arrives;

[0055] The detection module 52 is used to detect in real time whether the processing of the current frame data can be completed in the VSync period during the process of processing the current frame data;

[0056] The delay module 53 is configured to delay the VSync period by a predetermined time when the detection module determines that the processing of the current frame data cannot be completed within the VSync period.

[0057] In practical applications, the above-mentioned modules in this embodiment may be software, hardware, or a combination of both. For example, each of the above modules may be implemented by a CPU in an electronic device (for example, a mobile phone). In practical application, the above-mentioned appar...

Embodiment 3

[0060] An electronic device comprising:

[0061] monitor;

[0062] a memory storing a program for improving image fluency;

[0063] A processor configured to execute a program for improving image fluency to perform the operations of the method described in Embodiment 1.

[0064] For other technical details of this embodiment, reference may be made to Embodiment 1.

[0065] In this embodiment, the processor of the electronic device may include a CPU and a GPU.

[0066] like Image 6 Shown is a schematic structural diagram of an exemplary electronic device in this embodiment.

[0067] In an implementation manner, an electronic device may include: a CPU, a GPU, a memory, a display, a video controller, and a bus. Wherein, the CPU, the GPU, and the memory are respectively connected through buses. The CPU is responsible for calculating the display content and submitting it to the GPU. The GPU is responsible for rendering and other processing and puts the rendering result into ...

Abstract

The application publishes a method and device for improving smoothness of an image. The method comprises the steps of: when a VSync (Vertical Synchronization) signal sent out by a display arrives, starting processing of a current frame of data; in the process of processing the current frame of data, detecting whether processing of the current frame of data can be completed in a VSync period in real time; and when determining that processing of the current frame of data cannot be completed in the VSync period, delaying the VSync period by preset duration. According to the application, blockagecan be avoided, and display smoothness of the image or a video is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a method and device for improving image fluency. Background technique [0002] At present, electronic devices (such as mobile phones) basically use the mobile industry processor interface (Mobile Industry Processor Interface, MIPI) transmission protocol between the processing chip and the screen. According to the protocol, it can be divided into video mode and cmd mode. The two modes are transmitted in different ways, and the ways of generating the vertical synchronization signal (vertical synchronization, VSync) in the two modes are also different. If the video mode transmission mode is adopted, the VSync synchronization signal is sent by the processing chip of the electronic device. Calculated at a refresh rate of 60fps, a VSync is generated in about 16.7 milliseconds, that is to say, the processing chip of the electronic device needs to process the image to be displ...
