Description

A kind of double CCD CCTV camera

Technical field

This utility model is specifically related to a kind of double CCD CCTV camera.

Background technology

The CCTV camera of prior art generally use cmos sensor to gather picture signal, It is in the low monitoring camera poor effect shone under state, it is impossible to meet the requirement of fine definition.

Utility model content

The purpose of this utility model is for solving above-mentioned deficiency, it is provided that a kind of double CCD monitoring cameras Machine.

The purpose of this utility model is achieved through the following technical solutions:

A kind of double CCD CCTV camera, including EEPROM cell, synchronizing signal separator, Power subsystem, CCD colour processor, signal processor, video output unit, first CCD unit and the 2nd CCD unit, EEPROM cell, synchronizing signal separator, power supply Unit, signal processor, video output unit, a CCD unit and the 2nd CCD unit divide Not electricity Lian Jie CCD colour processor, power subsystem connect respectively synchronizing signal separator, Signal processor, a CCD unit and the 2nd CCD unit, synchronizing signal separator connects letter Number processor, a CCD unit and the 2nd CCD unit connect signal processor respectively.

CCD colour processor uses CXD3172AR chip.

Oneth CCD unit and the 2nd CCD unit use the ccd image sensing of ICX409AK Device.

This utility model has a following beneficial effect:

This utility model is reasonable in design, easy to use, uses double CCD unit to be monitored, prison Controlling effective, drawing paper is clear, has good application prospect.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described:

As it is shown in figure 1, a kind of double CCD CCTV camera, including EEPROM cell 1, synchronize Demultiplexer 2, power subsystem 3, CCD colour processor 4, signal processor 5, regard Frequently output unit the 6, the oneth CCD unit 7 and the 2nd CCD unit 8, EEPROM cell 1, Synchronizing signal separator 2, power subsystem 3, signal processor 5, video output unit 6, first CCD unit 7 and the 2nd CCD unit 8 are electrically connected CCD colour processor 4, power supply Unit 3 connects synchronizing signal separator 2, signal processor 5, a CCD unit 7 and respectively Two CCD unit 8, synchronizing signal separator 2 connects signal processor 5, a CCD unit 7 Signal processor 5 is connected respectively with the 2nd CCD unit 8.

CCD colour processor uses CXD3172AR chip.

Oneth CCD unit and the 2nd CCD unit use the ccd image sensing of ICX409AK Device.

Operation principle: CXD3172AR reads the systematic parameter configuration being stored in EEPROM, The port that the initial processes of plug-in reads arranges depositor.Due to CXD3172AR's Driving voltage meets the requirement of ICX409AK imageing sensor, it is not necessary to voltage conversion circuit. V1, V2, V3 and V4 are vertical transfer clock, and HiH2 is horizontal transfer clock, and RG is multiple Item, SUB is shutter signal.Electric charge in photosensitive pixel is driven lower turn by vertical transfer clock Moving to vertical register, horizontal transfer clock HiH2 controls horizontal register by optical charge progressively Being transferred to out amplifier, reset gate clock signal RG compares voltage for the offer when sampling, SUB is for realizing the control of time of exposure.Under External synchronization mode, synchronizing signal separator sends External synchronization signal EXT-VIDEO acts on CCD driving pulse by CXD3172AR, to reach Purpose to synchronous scanning.
