Embodiment 1

[0027] Step 1, intercepting the video signal output to the display;

[0028] First intercept the video signal output from an electronic device to the display. The method of intercepting the video signal is to divide the video signal on the video cable connecting the electronic device and the display, wherein: one path is still output to the display of the electronic device, and the other For real-time video capture;

[0029] The intercepted video signal is to truncate the video signal output from an electronic device to the display, and not output to the display of the electronic device, and directly used for video collection;

[0030] Step 2, collecting the intercepted video signal in real time, digitizing the video signal to obtain digitized video data;

[0031] Step 3: Carry out real-time signal processing on the digital video data, the real-time signal processing is to carry out single-frame image enhancement processing on the digital video data to obtain processed digita...

Embodiment 2

[0036] Step 1, intercepting the video signal output to the display;

[0037] First, intercept the video signal output from an electronic device to the display. The method of intercepting the video signal is to divide the video signal on the video connector connected to the electronic device and the display, wherein: one path is still output to the display of the electronic device, and the other One channel is used for real-time video acquisition;

[0038] The intercepted video signal is to receive the wireless video signal radiated by the video cable of an electronic device display in a wireless receiving manner, and then perform video collection on the received video signal.

[0039] Step 2 is the same as the scheme of Example 1;

[0040] Step 3, performing real-time signal processing on the digitized video data is the same as the solution in Embodiment 1, or the real-time signal processing is to perform image enhancement processing between image frames on the digitized vide...

Embodiment 3

[0044] Step 1 is the same as in embodiment 1 or embodiment 2;

[0045] Step 2 is the same as that of Example 1;

[0046] Step 3, performing real-time signal processing on the digitized video data to obtain processed digitized video data;

[0047] The real-time signal processing is to perform image conversion processing between image frames on the digitized video data to obtain processed digitized video data.

[0048] Step 4 is the same as in embodiment 1 or embodiment 2;

[0049] Step five: the same as in Example 1.

[0050] figure 2It is a schematic diagram of a display device for real-time interception and processing of video signals. The display device 200 for real-time interception and processing of video signals may include a video signal interceptor 201, a video signal collector 202, a signal processor 203, a video signal generator 204, and a display 205, wherein: The signal interceptor 201 is equipped with an arm to intercept a video signal output from an electroni...
