Problems solved by technology

Due to the randomness of user operations and the low sampling rate of system commands (for example, a maximum of 25 operating commands per second), this will lead to uneven time intervals for the control terminal to send commands to the display module, and the time interval for the display module to display images It is also not uniform, making the image changes of the two frames before and after the uneven
[0003] Such an image manipulation display system generally has one or more of the following characteristics: 1. The display module only displays the final picture after receiving the manipulation command sent by the control terminal; 2. The time interval between the two display pictures is uneven; 3. The display instruction intensity is low
[0004] Usually, such applications are only suitable for low frame rate image display systems. When the system needs to continuously move and zoom the display image at high speed, the screen image usually makes people feel that the picture has jitters, flickers or frames, instead of smoothness. , stable screen display

Embodiment 1

[0029] The present invention provides a method for optimizing the display effect of screen pictures, such as figure 1 as shown, figure 1 A flow chart of a method for optimizing the display effect of a screen image, specifically including:

[0030] Step S100, preset an expected frame rate, and obtain an expected time interval according to the expected frame rate. First, set the expected frame rate value. Generally, the default system expected frame rate is 60 frames per second, but it can also be set according to user needs. This value can be set when the system initialization starts. In this embodiment, a desired frame rate of 60 frames per second is used. Then follow the formula:

[0031] FrameInterval=1000 / desired frame rate

[0032] The expected time interval FrameInteval can be obtained by calculation, and the expected time interval in this embodiment is 16ms.

[0033] Step S200, issuing a manipulation command according to the collected image information and the recei...

Embodiment 2

[0058] The present invention provides a device for optimizing the display effect of screen pictures, such as Figure 4 as shown, Figure 4 A schematic diagram of a device for optimizing the display effect of a screen image, specifically including a control module, an image processing module and a display module. The three modules are described in detail below:

[0059] The control module is configured to issue manipulation commands according to the collected image information and received user commands. The collected image information includes a source image, a source display area and a target display area; the issued manipulation commands include panning and zooming.

[0060] The image processing module is used to receive and analyze the manipulation command sent by the control module, perform calculation according to the frame insertion algorithm and generate an image.

[0061] The display module is used to display the image produced by the image processing module.

Abstract

The invention relates to an image operation control display system and provides a method for optimizing the picture display effect of a screen. The method comprises the following steps: setting an expected frame rate in advance and obtaining an expected time interval according to the expected frame rate; sending out an operation control command according to the collected image information and thereceived user command; receiving the operation control command and judging whether frame insertion is needed or not according to an operation control time interval and the expected time interval; needing frame insertion if the operation control time interval is greater than the expected time interval, generating an image according to a frame insertion algorithm, inserting frames, displaying the image frame by frame and finally, displaying a final frame image; and otherwise, displaying the final frame image. The invention also provides a device for optimizing the picture display effect of the screen, which comprises a control module, an image processing module and a display module. The invention can realize balanced and stable picture display and bring better visual experience.

Description

technical field [0001] The invention relates to an image manipulation and display system, in particular to a method and device for optimizing the display effect of screen images. Background technique [0002] In the existing image manipulation and display system, the control terminal usually only sends a manipulation command to the display module after receiving the user manipulation command, and usually only responds to the received user manipulation command once, instructing the display module to select a certain position on the screen. The area of ​​the screen is displayed to a certain area of ​​the screen; at the same time, the display module usually directly displays the final screen after receiving the manipulation instruction sent by the control terminal. Due to the randomness of user operations and the low sampling rate of system commands (for example, a maximum of 25 operating commands per second), this will lead to uneven time intervals for the control terminal to ...
