Abstract
The invention discloses a video capture system for a remote teaching live broadcast system. The video capture system comprises a camera with at least 2000 000 pixels per inch, a noise reduction unit, a central processing unit and a storage system, wherein the camera is used for capture and generating a video signal, the noise reduction unit is connected with the camera, the central processing unit is connected with the noise reduction unit, and is used for carrying out format compression conversion on an image processed by the noise reduction unit through noise reduction , and the storage system is used for receiving and storing the video signal converted by the central processing unit. The noise reduction unit is on the basis of an image self-adaptation algorithm, the camera is a CCD camera, and the central processing unit is a reduced instruction set computer based on an ARM9 framework. By the adoption of the technical scheme of the video capture system for the remote teaching live broadcast system, an original video image can be captured more effectively through addition of simple devices, and due to the fact that the adopted technologies are mature, the cost is low, and large-scale production and application are convenient.
Description
Technical field
The present invention relates to a kind of video acquisition system that is applied to distance education live-cast system.
Background technology
The existing education system of China is very huge, traditional education is all take student and teacher as main, teacher's teaching task is conventionally all very heavy, a kind of distance education live-cast system occurring now can effectively address this is that, but, the video acquisition system of traditional live broadcast system, it is all the prior art adopting, hardware device is not optimized for tutoring system, and bulky, is not too applicable to classroom teaching environment.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of video acquisition system that is applied to distance education live-cast system of development comprises
Pixel is at least the camera of 200W, gathers and generating video signal:
The noise reduction unit being connected with this camera;
The CPU being connected with described noise reduction unit, by the image after described noise reduction unit noise reduction, carries out format compression conversion;
Storage system, receives and stores the volume vision signal that described CPU is changed.
Described noise reduction unit is based on image adaptive algorithm.
Described camera is CCD camera.
Described CPU is the Reduced Instruction Set Computer based on ARM9 framework.
Owing to having adopted technique scheme, a kind of video acquisition system that is applied to distance education live-cast system provided by the invention, by increasing simple equipment, can the original video image of more efficiently collection, and use is all ripe technology, with low cost, be extremely convenient to large-scale production and use.
