Problems solved by technology

[0004] However, the above-mentioned screen mirroring projection and specific projection cannot adjust the display range of the projection image, that is, the display device cannot adjust the display size, display area and other parameters of the display image, and the display device can only display the projection in full screen. The image sent by the screen device; and when the screen projection device is a vertical screen device and the display device is a landscape device, the screen projection device sends a vertical screen projection image, and the display device can only shrink the projection image and display it, so that There are a large number of black border areas in the display screen, which seriously affects the display effect

Embodiment Construction

[0049] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0050] see Figure 1a , is a schematic diagram of a screen projection display method according to a specific embodiment of the present invention. Wherein, the screen projection display method involves a screen projection device 101 and a display device 102. It can be seen from the figure that the screen projection device 101 generates a screen projection image 103 and sends it to the display device 102, and the display device 102 displays the projection image 103. The image of a partial area in the screen image 103, thereby realizing a specific projection screen display. Wherein, the display device 102 can receive and display an image of a partial area of ​​the screen projection image 103 sent by the screen projection device 101 . Fo...

Abstract

The invention relates to the technical field of image display, and provides a projection screen display method, a system and a storage medium. The method comprises the following steps: receiving projection screen images sent by more than one projection screen device in real time; Selecting a sub-image from the projection image; processing and displaying The sub-image on the display screen in realtime. different from the prior art, the projection screen device only needs to send a complete projection screen image, and the display device selects sub-images from the projection screen image for display, and the display device can display the sub-images after processing, so that the image projection screen display is more flexible, and the image projection screen display has better display effect and better versatility.

Description

technical field [0001] The present invention relates to the technical field of image display, in particular to a screen projection display method, system and storage medium for projecting an image from one device to another device. Background technique [0002] Screen projection refers to projecting the display image of device A to device B, so that device B can also display the display image of device A synchronously. Screen projection technology can project the display image of a device with a small display screen (such as a mobile phone, a tablet computer) to a large-screen display device (such as a TV, a car multimedia display), so as to achieve better viewing effects and facilitate Share display images with multiple people. [0003] In the prior art, there are mainly two common screen projection methods, one is screen mirror projection, that is, all the content displayed by device A (that is, the screen projection device) is completely projected to device B (that is, t...
