Detailed description of the invention
By describing the technology contents of the present invention, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
Referring to Fig. 2, photographic head of the present invention shares the structural representation processing construction embodiment, shown in figure, and should
Process chip 1 include P1 and P2 signal processing input port, P1 port includes 8 pins, be respectively P1.0, P1.1, P1.2,
P1.3、P1.4、P1.5、P1.6、P1.7；P2 port includes 8 pins, be respectively P2.0, P2.1, P2.2, P2.3, P2.4,
P2.5、P2.6、P2.7.8 data line of the first photographic head 2A are referred to as 4 numbers after the first front-end signal processing module 3A processes
Send into 8 data line of P1.0～P1.3, second camera 2B according to line after the second front-end signal processing module 3B processes, be referred to as 4
Data line sends into P1.4～P1.7, and 8 data line of the 3rd photographic head 2C are after the 3rd front-end signal processing module 3C processes
Being referred to as 4 data line and send into P2.0～P2.3,8 data line of the 4th photographic head 2D are at the 4th front-end signal processing module 3D
It is referred to as 4 data line after reason and sends into P2.4～P2.7.Process chip also include front-end signal processing module control terminal KZ1,
KZ2, KZ3, KZ4, front-end signal processing module control terminal KZ1 are used for controlling the first front-end signal processing module 3A work, front
End signal processing module control terminal KZ2 is used for controlling the second front-end signal processing module 3B work, front-end signal processing module
Control terminal KZ3 is used for controlling the 3rd front-end signal processing module 3C work, and front-end signal processing module control terminal KZ4 is used for
Control the 4th front-end signal processing module 3D work.
Certainly, a front-end signal processing module can connect and connects a photographic head, it is also possible to a front-end signal processes
Module connects plural photographic head, or by front-end signal processing module composition tree structure or network structure, only
If making multiple photographic head by front-end signal processing module to be connected with the process port processing chip, reaching multiple and taking the photograph
As head shares a structure processing port, all it is considered as the equivalent of the present invention, falls into protection scope of the present invention.
The first above-mentioned front-end signal processing module 3A may be located at inside the first photographic head 2A, as the one of internal circuit
Part.This first front-end signal processing module 3A can also be positioned at the outside of the first photographic head 2A, becomes peripheral circuit.
The second above-mentioned front-end signal processing module 3B may be located at inside second camera 2B, as the one of internal circuit
Part.This second front-end signal processing module 3B can also be positioned at the outside of second camera 2B, becomes peripheral circuit.
The 3rd above-mentioned front-end signal processing module 3C may be located at inside the 3rd photographic head 2C, as the one of internal circuit
Part.3rd front-end signal processing module 3C can also be positioned at the outside of the 3rd photographic head 2C, becomes peripheral circuit.

Part.4th front-end signal processing module 3D can also be positioned at the outside of the 4th photographic head 2D, becomes peripheral circuit.
Above-mentioned front-end signal processing module is mainly used in being adjusted the image signal of photographic head so that the width of signal
The gap of degree reduces, and the fluctuation of amplitude reduces so that signal is more prone to process.The image signal level produced such as photographic head is
0～255, the image signal level after being processed by front-end signal processing module becomes 0～128, and so original needs takies
Process the signal of 8 pins of chip, the most just need only to take 4 pins processing chip.By that analogy, if
In the case of picture quality allows, it is possible to use the image signal level after front-end signal processing module processes can become more
Little, so that can be with the corresponding multiple photographic head of a signal processing input port.
The image signal level that photographic head produces can also be 0～1024, after being processed by front-end signal processing module
Image signal level become 0～4,0～8,0～16,0～32,0～64,0～128,0～256 or 0～512, such a
Signal processing input port just can corresponding multiple photographic head.
See Fig. 3, the structural representation of an alternative embodiment of the invention, shown in figure, process the input of chip 1 '
Mouth is 8～32 input terminals, and the first shooting 2A ', second camera 2B ', the 3rd photographic head 2C ' or the 4th photographic head 2D ' have 8
～32 lead-out terminals, this first photographic head 2A ', second camera 2B ', the 3rd photographic head 2C ' or the 8 of the 4th photographic head 2D '
～2～31 terminals in 32 lead-out terminals directly electrically connect with the input terminal processing chip 1 '.
First photographic head 2A ' also has the first signal Enable Pin SK1, and second camera 2B ' also has secondary signal and enables
End SK2, the 3rd photographic head 2C ' also have the 3rd signal Enable Pin SK3, and the 4th photographic head 2D ' also has the 4th signal Enable Pin
SK4, the first signal Enable Pin SK1 and secondary signal Enable Pin SK2 by synchronization module 4A ' carry out with logical operations after at feeding
First group of I/O mouth Enable Pin of reason chip, the 3rd signal Enable Pin SK3 and the 4th signal Enable Pin SK4 are by synchronization module 4B '
Carry out with logical operations after feeding process chip second group of I/O mouth Enable Pin.Process chip and also there is synchronization module control end
Sub-KT1 and KT2, control terminal KT1 are used for controlling synchronization module 4A ' work, and control terminal KT2 is used for controlling synchronization module 4B '
Work.
Certainly, a synchronization module can connect a photographic head, it is also possible to a synchronization module connects plural taking the photograph
As head, or by synchronization module composition tree structure or network structure, as long as make multiple shooting by synchronization module
Head is connected with the process port processing chip, reaches multiple photographic head and shares a structure processing port, all should recognize
For being the equivalent of the present invention, fall into protection scope of the present invention.
Above-mentioned photographic head can be the photographic head of less than 1,000,000, can also be the shooting of more than 1,000,000 pixels further
Head.Further, this photographic head can be with infrared lamp so that this photographic head becomes day and night type photographic head.
Therefore, the present invention proposes the new structure of the corresponding two or more photographic head of a signal processing input port,
So can be cost-effective, and the quantity of minimizing data wire, reduce EMI.
