Abstract
The present invention relates to a rearview device for car, belonging to the field of car rearview technology by utilizing camera head and display to display exterior and interior circumstance of car. The rearview device technique is implemented by mounting video camera heads on the different positions or car body, on the control panel of the car the display connected with every camera head is set, over the front wind screen in the interior of the car a camera head toward car interior is set, and the left rearview mirror position and right rearview mirror position of external car body are respectively equipped with left camera head and right camera head, and the tail portion of the car is equipped with a rear camera head toward car rear direction.
Description
Technical field
The present invention relates to automobile different azimuth scenery technique of display, particularly show the anti-visual organ of automobile of the inside and outside scape of car by camera.
Background technology
As everyone knows, anaglyphoscope, back mirror are the essential annexes of each car, place the preceding left side of vehicle, the preceding right-hand and interior front upper place of car respectively, its objective is for chaufeur drive, accurately grasp when moveing backward vehicle left and right, after situation, guarantee that vehicle when travelling and move backward and the safety of left and right, the back object of vehicle, prevents the generation of all kinds of accidents.Up to now, the anaglyphoscope of vehicle, back mirror major part are glass-mirror, look unfamiliar with this glass and produce various counter the looking form, and the backsight condition is removed frangible, instead look, the backsight effect bad outside because anaglyphoscope has certain volume can also have influence on the speed of vehicle.
Summary of the invention
The present invention seeks to defective, design a kind of chaufeur and be easy to observe backsight, the anti-anti-visual organ of, easy to install automobile of looking effective at the prior art existence.
The object of the invention can be achieved through the following technical solutions:
The anti-visual organ of automobile is to be provided with video frequency pick-up head at the car body different parts, is provided with the telltale that joins with each camera on automobile control panel.Be provided with the camera in car before automobile above in the windshield, the left and right back mirror place outside automobile on the car body is provided with left camera and right camera respectively, is provided with back camera behind car at automobile tail.The anti-visual organ of automobile is located at the outer camera of car body and is promptly can be hiding telescopic or stationary structure.Its described camera is an automatic or manual focusing camera.
The anti-visual organ of automobile and camera, telltale are connected to video recording equipment.
The invention has the advantages that, be easy to driver's observation, good visual effect, the orientation is comprehensive.
Description of drawings
Fig. 1 is a circuit catenation principle scheme drawing of the present invention;
Fig. 2 is a camera of the present invention installation site scheme drawing;
Fig. 3 is the embodiments of the invention schematic circuit diagram.
Specific implementation method
The anti-visual organ of automobile is to be provided with video frequency pick-up head at the car body different parts, is provided with the telltale that joins with each camera on automobile control panel.Before automobile, be provided with the camera 1 in car above in the windshield, on the outer car body of automobile, be provided with left camera 3 and right camera 4 respectively, be provided with back camera 2 behind car at automobile tail at left and right back mirror place.In actual use, the described outer camera of car body of being located at can be and hides flexible or stationary structure, and camera promptly can be a fixed focal length, also can be the automatic or manual camera of focusing.For ease of record, anti-visual organ of automobile and camera, telltale can be connected to video recording equipment.
The invention process circuit as shown in Figure 3, all-weather black-white CCD pick up camera circuitry schematic diagram.This circuit mainly is made up of four integrated circuit and other peripheral circuits that Sony Corporation produces, and its horizontal resolution can reach 400 tv lines, and output signal-to-noise ratio can reach 43dB, 0 candle light illumination.These four integrated circuit are finished electric conversion, video processing, function such as generation and field frequency driving, introduction respectively below synchronously respectively.
(1) photoelectric switching circuit: photoelectric switching circuit is by IC
1(ICX045BLA) constitute, this circuit is actually a slice 8.5mm (1/3in) ccd image sensor integrated circuit.Scenery is by become a real image behind the optical lens on the target surface of ccd image sensor, because each unit (pixel) on the target surface all is a photosensitive unit, so these photosensitive units are under different illumination, with the weak current of output varying strength.With the television system of 15625Hz (line frequency)/50Hz (field frequency) to IC
1Scan, can pick up out IC
1The electric signal that reaches the variation of illuminance of ccd fpa in time and export.
(2) video processing circuits: video processing circuits is by IC
2(CXD1310AQ) constitute, it comprises signal conditioning, mixed blanking, video phase and built-in AGC closed loop video amplifier etc.With IC
1The faint vision signal of imageing sensor output carries out corresponding level conversion and auto brightness control is amplified, and gets final product the 1V of outputting standard
PPVision signal.
(3) synchronous circuit: synchronous circuit IC
3(CXD1254AQ) can produce the required clock pulse of 15625Hz/50Hz scanning system, inter-sync signal, signal conditioning pulse, speed change electronic shutter, time pulse and composite synchronizing signal, strict sequential be arranged, between these pulses by clock control.The clock reference frequency of this machine is 18.9375MHz, through IC
1Interior 1212 frequency dividers are got f
hThe line frequency signal of=15625Hz is got f through 625 frequency dividers again
vThe field frequency signal of=50Hz, they are respectively applied for and drive row, field frequency circuit.
(4) driving circuit: IC
4(CXA1250) handle integrated circuit for field frequency drives, it comprises 4 ccd image sensing actuators, two outer output pulse generators, electronic shutter pulse driver etc.This circuit can be with IC
3The impulse singla level conversion that synchronous circuit produces also is amplified to required amplitude.
Claims (4)
1, the anti-visual organ of automobile is characterized in that: be provided with video frequency pick-up head at the car body different parts.On automobile control panel, be provided with the telltale that joins with each camera; Be provided with the camera in car above in shield glass; Left and right back mirror place outside automobile on the car body is provided with left camera and right camera respectively; Be provided with back camera behind car at automobile tail.
2, the anti-visual organ of automobile according to claim 1 is characterized in that: the described outer camera of car body of being located at is for hiding flexible or stationary structure.
3, the anti-visual organ of automobile according to claim 1 and 2 is characterized in that: described camera is an automatic or manual focusing camera.
4, the anti-visual organ of automobile according to claim 1 and 2 is characterized in that: be connected to video recording equipment with camera, telltale.
