Abstract
The invention discloses a kind of light filling adjustable photographic head illuminator, including photographic head, also include the controller being connected with photographic head and the sensing device, light compensating apparatus, light modulating device and the external input terminals that are connected with controller；After photographic head is opened, sensing device is started working, the information gathering the light intensity in environment and spectrum is sent to controller, the control parameter comparison that the information collected is inputted by controller with external input terminals, generate control signal and be sent to light compensating apparatus and light modulating device, light compensating apparatus and light modulating device according to control signal work.The invention have the advantage that there is sensing device, brightness and spectrum can be carried out controllable adjustment；Sensing device is embedded in photographic head, and volume is little, low cost.
Description
Technical field
The present invention relates to a kind of photographic head, be specifically related to a kind of light filling adjustable photographic head illuminator.
Background technology
Photographic head is also called camera computer, computer eye, electronic eye etc., is a kind of video input apparatus, is used widely
In aspects such as video conference, tele-medicine and monitoring in real time.Common people can also have at network each other by photographic head
Image, the talk having sound and communication.It addition, people can also use it for current various popular digital image, audio-visual place
Reason.Photographic head can be divided into digital camera and the simulation big class of photographic head two.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 captures
Number have to pass through specific capure card and convert analog signals into figure pattern, and just may switch to meter after being compressed
Use on calculation machine.Digital camera can directly catch image, is then passed in computer by string, parallel port or USB interface.
Photographic head on computer market is substantially based on digital camera, and to use new types of data coffret in digital camera
USB digital camera be main, on market, visible major part is all this product.In addition also has a kind of and video acquisition
Block with the use of product, but be not the most main flow.Due to popularizing rapidly of PC, the holistic cost of simulation photographic head is relatively
Height, and the reasons such as BSV liquid crystal-spliced screen interface can not be met, the transmission speed of USB interface is significantly larger than the speed of serial ports, parallel port
Degree, the therefore digital camera of market USB interface.Simulation photographic head can be supporting with video frequency collection card or USB video frequency collection card
Using, use with computer connects very easily, typical case's application is general recording monitor.Clean area photographic head, clean area embeds
Formula special camera is the special camera monitored in real time for clean area dust free room visual plant key post.This photographic head is pure
Surface plate, embeds color steel and installs, zero corner or spot as yet untouched by a clean-up campaign, and easy to clean, it is convenient to install, and can quickly deploy to ensure effective monitoring and control of illegal activities by multiple spot, and compatible main flow regards
Frequently system photographic head typically has the basic functions such as video camera/propagation and still image seizure, and it is by camera lens collection figure
After Xiang, by the photosensory assembly circuit in photographic head and control assembly image is processed and converted to the number that computer can identify
Word signal, then connects by parallel port or USB and is carried out image restoring after being input to computer by software again.
Existing photographic head image noise ambient light is more weak when is bigger, and 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.
Summary of the invention
The technical problem to be solved is light filling and the light modulation of photographic head, it is therefore intended that provide a kind of light filling adjustable
Photographic head illuminator, solve existing photographic head image noise ambient light is more weak when bigger, picture quality
Low, and have some to have employed the photographic head problem due to light source of light compensating apparatus, image color distortion is serious and has no idea
The problem being adjusted.
The present invention is achieved through the following technical solutions:
A kind of light filling adjustable photographic head illuminator, including photographic head, also include the controller that is connected with photographic head and with control
Sensing device, light compensating apparatus, light modulating device and the external input terminals that device processed connects；
Sensing device: gather the information of the light intensity in environment and spectrum, and send it to controller；
Light compensating apparatus: environment is carried out light filling 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 controller；
Controller: receive sensing device and send the information of the light intensity in environment and spectrum, according to the control of external input terminals input
Parameter generates control signal and is sent to light compensating apparatus and light modulating device, or the control signal that external input terminals inputs is directly transmitted
To light compensating apparatus and light modulating device.After photographic head is opened, sensing device is started working, and gathers the letter of the light intensity in environment and spectrum
Breath is sent to controller, and controller, by the information collected and the control parameter comparison of external input terminals input, generates and controls letter
Number it is sent to light compensating apparatus and light modulating device, light compensating apparatus and light modulating device work according to control signal.
Described light compensating apparatus is white led lamps.Fully, brightness is high, low cost in illumination, saves the energy.
Described light modulating device is that red LED, green LED and blue led combine.Can generate big by RGB color matching
Partial spectrum.
Described sensing device is embedded in photographic head.Reduce volume, reduce cost.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, one light filling of the present invention adjustable photographic head illuminator, has sensing device, can carry out controlled to brightness and spectrum
Regulation；
2, one light filling of the present invention adjustable photographic head illuminator, sensing device is embedded in photographic head, and volume is little, cost
Low.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing being further appreciated by the embodiment of the present invention, constitutes of the application
Point, it is not intended that the restriction to the embodiment of the present invention.In the accompanying drawings:
