Description
Technical field
This utility model is related to a kind of photographic head, and in particular to a kind of adjustable light video camera head with light identification.
Background technology
Photographic head is also called camera computer, computer eye, electronic eye etc., is a kind of video input apparatus, is widely used
In aspects such as video conference, tele-medicine and monitor in real time.Common people can also be had in network each other by photographic head
Image, the talk for having sound and communication.In addition, people can also use it for current various popular digital images, audio-visual place
Reason.Photographic head can be divided into digital camera and simulation two big class of photographic head.Video capture device can be produced by digital camera
Analog video signal be converted into digital signal, and then be stored in computer.The video letter that simulation photographic head is captured
Number have to pass through specific capure card and convert analog signals into figure pattern, and after being compressed, just may switch to meter
Use on calculation machine.Digital camera can directly catch image, then be passed in computer by string, parallel port or USB interface.
Photographic head on computer market substantially based on digital camera, and with using new types of data coffret in digital camera
USB digital cameras based on, on market, visible major part is all this product.In addition there is a kind of and video acquisition
The product that card is used cooperatively, but be not also main flow.Due to the rapid popularization of PC, simulate the holistic cost of photographic head compared with
Height, and the reasons such as the liquid crystal-spliced screen interfaces of BSV can not be met, the transmission speed of USB interface is significantly larger than serial ports, the speed of parallel port
Degree, therefore the digital camera of market USB interface.Simulation photographic head can be supporting with video frequency collection card or USB video frequency collection cards
Use, very easily use with computer connection, typical case's application is general recording monitor.Clean area photographic head, clean area are embedded in
Formula special camera is the special camera for clean area dust free room visual plant key post monitor in real time.The photographic head is pure
Surface plate, is embedded in color steel and installs, zero corner or spot as yet untouched by a clean-up campaign, easy to clean, install convenient, quickly multiple spot can deploy to ensure effective monitoring and control of illegal activities, and compatible main flow is regarded
Display system photographic head typically has the basic function such as video camera/propagation and still image seizure, and it is by camera lens collection figure
As after, image is carried out being processed and converted to the number that computer can be recognized by the photosensory assembly circuit and control assembly in photographic head
Word signal, is then input to after computer and carries out image restoring again by software by parallel port or USB connections.
Existing photographic head when ambient light is weaker image noise than larger, picture quality is low, and has some to adopt
With the photographic head of light compensating apparatus due to the problem of light source, image color distortion is serious and has no idea to be adjusted.
Utility model content
Technical problem to be solved in the utility model is the light filling of photographic head and light modulation, it is therefore intended that provide a kind of band light
The adjustable light video camera head of line identification, solve existing photographic head when ambient light is weaker image noise than larger, image
Quality is low, and has some to employ the problem of the photographic head due to light source of light compensating apparatus, and image color distortion is serious and does not have
The problem that method is adjusted.
This utility model is achieved through the following technical solutions：
A kind of adjustable light video camera head with light identification, including photographic head, also include the controller that is connected with photographic head and
Sensing device, light compensating apparatus, light modulating device and the external input terminals being connected with controller；
Sensing device：The information of light intensity and spectrum in collection environment, and send it to controller；
Light compensating apparatus：Light filling is carried out to environment according to the control signal of controller；
Light modulating device：The spectrum of environment is adjusted according to the control signal of controller；
External input terminals：Outside control signal or control parameter are input to into controller；
Controller：The information that sensing device sends the light intensity in environment and spectrum is received, according to external input terminals input
Control parameter generates control signal and is sent to light compensating apparatus and light modulating device, or the control signal that external input terminals are input into is direct
It is sent to light compensating apparatus and light modulating device.After photographic head is opened, sensing device is started working, and gathers the light intensity in environment and spectrum
Information be sent to controller, the information for collecting and the control parameter contrast of external input terminals input are generated control by controller
Signal processed is sent to light compensating apparatus and light modulating device, and light compensating apparatus and light modulating device work according to control signal.
The light compensating apparatus are white led lamps.Illumination is abundant, and brightness is high, low cost, energy saving.
The light modulating device is combined for red LED, green LED and blue led.Can be generated by RGB color matchings big
Partial spectrum.
The sensing device is embedded in photographic head.Reduce volume, reduces cost.
This utility model compared with prior art, has the following advantages and advantages：
1st, a kind of adjustable light video camera head with light identification of this utility model, with sensing device, can be to brightness and spectrum
Carry out controllable adjustment；
2nd, a kind of adjustable light video camera head with light identification of this utility model, sensing device are embedded in photographic head, volume
It is little, low cost.
