Abstract

The invention discloses a device capable of simultaneously capturing pictures of a main screen and an extended screen. The device comprises a control module, a voice receiving module and a control panel which are connected to the input end of the control module, an acquisition module electrically connected with the control module and having double acquisition ports, a signal detection module electrically connected with the acquisition module and the control module respectively, a communication module connected to the output end of the control module, as well as the main screen and the extended screen connected to the input end of the signal detection module. The device has the advantages that double video signals can be simultaneously input by automatically detecting signal sources input from the main screen and the extended screen, so that the video acquisition performance is improved; and the device is convenient to use and strong in practicability.

Description

technical field [0001] The invention belongs to the field of electronic equipment, and in particular relates to a device capable of capturing images of a main screen and an extended screen at the same time. Background technique [0002] A video capture card is also called a video card, which is used to input video data or mixed data of video and audio output from an analog camera, video recorder, LD video disc player, TV output, etc. into a computer, and convert it into digital data that can be identified by the computer. Stored in the computer, it becomes an editable video data file. Traditional video capture equipment can only capture a single video signal source because it cannot perform input signal detection on multiple signal sources. Therefore, there is a need for a screen acquisition device that can acquire multiple signal sources by detecting the input of the signal sources, which has solved the shortcomings in the prior art. Contents of the invention [0003] T...
