The optical fiber signal transceiver module is used for receiving and forwarding image data transmitted by a front-end camera; the image processing module is used for processing the received image data to form visual images; the signal conversion module is used for converting the visual images into signals of multiple commonly used formats; and the interfaces are used for outputting or connecting corresponding processing or display devices.
Description
Technical field
This patent relates to a kind of digital camera.
Background technology
Along with the direction of rig camera towards high definition develops, the signal transmission form that adopts in traditional video camera and interface can not adapt to the variation of application demand.For example: the output interface of web camera is network interface, for the equipment that adopts the HD-SDI interface, no matter signal specification and interface all can't directly use.Equally, for the HD-SDI video camera, be linked into the equipment of other signal specification and interface, also have incompatible problem.
Though can adopt conversion equipment changes unlike signal specification and interface, to adapt to the service condition of follow-up equipment, but this mode of dealing with problems from the surface is not only brought the unfavorable factor that cost increases and power consumption increases, and making system's structure become complicated, use, maintenance cost improve.
The utility model content
The purpose of this patent is to overcome the defective that above-mentioned prior art exists, and utilizes a kind of device, using optical fiber to optimize on the basis of camera signal transmission, expands the signal output interface of answering land used at camera signal, makes follow-up equipment to use easily.
Video camera uses at the signal of answering land used and can be divided into two classes, and a class is to observe display application, and another kind of is the signal application that continues.Last class provides signal to display device, and back one class provides original signal to follow-up equipment.
Comprise: the fiber-optic signal transceiver module: described fiber-optic signal transceiver module is used for receiving and transmits front-end camera by the view data of Optical Fiber Transmission;
As we can see from the figure, the front end high definition video that is transmitted by optical fiber is input to this device, and this device sends it when receiving this signal again via optical fiber, offer next optical fiber HD video treatment facility; For the equipment that uses the optical fiber input also can receive this high-definition video signal, this device converts the fiber-optic signal that receives to the signal of telecommunication, and after image is handled, convert as monitoring fields such as Analog Composite Video, HD-SDI video, Internet video vision signal specification commonly used the signaling interface output of adopting these signal specifications to adopt to.Simultaneously, this device is exported the accurate signal that shows of a road sign to display device as other video-unit, and this device adopts HDMI specification and interface.
Realize the technical scheme of above-mentioned purpose:
A kind of device with the expansion of video camera output interface comprises fiber optical transceiver, image processing module, signal conversion module, HDMI display interface, analog composite video signal interface, HD-SDI signaling interface, network video signal interface.
Described fiber optical transceiver receives the data image signal that transmits via optical fiber, and after receiving signal with its forwarding (giving next optical fiber image treatment facility); The described data image signal that transmits via optical fiber that receives forms common visual image (24 RGB or YUV/YC through image processing module
bC
rForm), and through the HDMI display interface to the display device output image; Through the analog composite video signal interface to the simulated television output image and to the treatment facility output image signal that receives analog composite video signal; Through the HD-SDI signaling interface to HD-SDI signal handling equipment output image signal; Through the Internet video interface to Internet video treatment facility output image signal.
The technical program is specially adapted to video surveillance applications, be the boundary with transmission medium optical fiber, fore-end is the video camera of output raw image data, and the rear end receives behind the raw image data its processing and sends to each interface, for the equipment use of unlike signal specification.
Adopt technique scheme, this patent beneficial technical effects is:
(1) at front end, video camera only needs to transmit signal with a kind of form to the back-end by optical fiber, makes that front-end architecture is simple, power consumption reduces;
(2) can directly adopt the Optical Fiber Transmission image, solve the long Distance Transmission of picture signal simply and easily;
(3) converting signal to various modes commonly used in the rear end uses in order to offer different equipment with form.

Embodiment
A kind of video camera output interface expanding unit, as shown in Figure 2, transmission medium adopts optical fiber, comprises front-end camera 1, fiber optical transceiver 2, image processing module 3, signal conversion module 4.The DID of front-end camera 1 output is received by fiber optical transceiver 2 by Optical Fiber Transmission, and fiber optical transceiver 2 forwards received signal when passing the signal to image processing module 3 via fiber optical transceiver 2; Image processing module 3 forms common visual image with the digital image signal that fiber optical transceiver 2 sends over through the image processing links, and be sent to signal conversion module 4 through the HDMI display interface to the display device output image and through the analog composite video signal interface to the simulated television output image and to the treatment facility output image signal that receives analog composite video signal and through the HD-SDI signaling interface to HD-SDI signal handling equipment output image signal and through the Internet video interface to Internet video treatment facility output image signal.
