Video signal real-time intercepting, processing and displaying method and device

Abstract

The invention provides a video signal real-time intercepting, processing and displaying method and device. The video signal real-time intercepting, processing and displaying device comprises a video signal intercepting device, a video signal collecting device, a signal processor, a video signal generator and a displaying device, wherein the video signal intercepting device is used for intercepting a video signal outputting by an electronic device to the displaying device; the video signal collecting device is used for collecting the video signal and converting the video signal into digital video data; the signal processor is used for performing real-time signal processing on the digital video data; the video signal generator is used for converting the digital video data subjected to the real-time signal processing into a video signal capable of driving the displaying device to perform display; the displaying device is used for displaying the output video signal subjected to processing. The invention further provides the video signal real-time intercepting, processing and displaying method. By means of the video signal real-time intercepting, processing and displaying method and device, data output by the specific electronic device to the displaying device can be extracted in real time, functions and applications of the existing device can be expanded by performing real-time signal processing on the data, and development of specific real-time applications based on the display data of the device is achieved.

Description

technical field [0001] The invention relates to the technical field of real-time processing and display of video signals, in particular to a method and device for real-time interception, processing and display of video signals. Background technique [0002] Currently, many electronic devices are equipped with a display as an information display device for human-computer interaction, which can display information of the electronic device on the display in real time. For electronic equipment with image processing and display, the display also displays the processed data, images or videos. [0003] Electronic equipment with a display, especially a dedicated electronic equipment with a display for a specific application, is generally customized by the manufacturer, and the expansion of its data processing function and display function is often limited by the equipment manufacturer. Users or application developers often cannot directly use the data generated by the device to ext...
