Now referring again to Figure 90, it should be appreciated that in order to provide to doctor from multiple camera shootings rapidly and in real time The simultaneous display of head should handle in real time and synchronize the image data from each camera sensing device before display. This should be completed in a manner of reducing delay to the maximum extent, and at the same time it is ensured that high quality exports.Therefore, this specification institute The video processing architecture stated supports three major functions:
A) the signal transmission and control that each camera is realized in a manner of most preferably shared resource, to reduce needs By the sum for the signal that cable transmits, signal transmission is carried out using smaller/thinner cable while still ensuring that height to obtain The ability of signal-to-noise ratio；
B) processing of camera data, wherein data are processed independently to ensure not postpone, and are then synchronized； With
C) data that transmit that treated in a manner of most preferably shared resource are to be shown.
These functions of video processing architecture are further illustrated below with reference to Figure 100 and 101.For using before one The embodiment of camera and two side cameras, conventional processing system for video need to transmit 36 independent signals, wherein Each camera has 12 associated signals, including 11 control signals and 1 video backhaul signals.Similarly, right In the implementation using two cameras (such as a preceding camera and a side camera, or only there are two side cameras) Example, conventional processing system for video need to transmit 24 independent signals.In one embodiment, it is taken the photograph to effectively operate Vision signal is received as head and from camera, needs following signals:
1.V01- vertical register clock
2.V02- vertical register clock
3.V03- vertical register clock
4.V04- vertical register clock
5.H01- horizontal register clock
6.H02- horizontal register clock
7.RG- resets gateable clock
8.VDD- supply voltage (15V)
9.VL- supply voltage (- 7.5V)
10.SUB- substrate clock
11.LED- light-emitting diodes tube voltage
12.Vout- video output signals
13. ground connection
Although ground signalling be it is public, to camera circuit board (such as the electronic circuit board component of Fig. 2A, 2B 400) transmission and its of 36 signals each of (three camera need 12 signals) is received from camera circuit board It is about the cable of 3mm that remaining signal, which needs diameter, is just able to achieve acceptable signal-to-interference ratio, it is contemplated that having in endoscope end Space is limited, this size is too big.Will lead to vision signal using the lesser cable of diameter has unacceptable high noisy.
Referring again to Figure 90, embodiment described herein can using small diameter cable (that is, about 2.5mm or It is smaller), to save the expensive real estate in endoscope lumen.For this purpose, a reality of Video Controller 9020 disclosed herein Example one group of signal (as shown in Figure 81) for generating quantity and being less than/be less than conventional 36 required signals is applied, this group of signal is by controlling Device 9020 is sent to the circuit board (such as electronic circuit board component 400 of Fig. 2A, 2B) in endoscope end, then by circuit Plate processing, to provide required concrete signal instruction for each camera.This allows system to control all necessary signals, and Without using 36 different signals.Although moreover, it will be recognized by one of ordinary skill in the art that in disclosed Video Controller The signal processing being described in detail in 9020 is to illustrate for the endoscope embodiment for observing element using three, but it is also the same Suitable for using the embodiment of two observation elements.
In one embodiment, preceding nine control signals (V01, V02, V03, V04, H01, H02, RG, VDD and VL) are logical It crosses and separates signal in the circuit board (such as electronic circuit board component 400 of Fig. 2A, 2B) in the optics end of endoscope 9010 And it taps in camera head and is shared between camera.Remaining signal is not shared.For example, SUB signal is for each Camera is specific, because they are used for " shutter control ".Therefore, in this embodiment, system is three cameras Use independent SUB1, SUB2 and SUB3 signal.In addition, independently and respectively to the LED circuit power supply for illumination.Cause This has three signals -- LED1, LED2 and LED3 for LED supply voltage in this embodiment.Due to nine letters Number be shared, therefore the sum of signal needed for operating three cameras is reduced from 36 to 18, including three individually Video output signals.Therefore, disclosed Video Controller 9020 generates multiple specific to each camera/observation element Signal and the multiple shared signals of each camera/observation element are non-specific for, to reduce the signal for needing to transmit Sum.
Figure 100 is the shared signal for listing each camera in detail and the table of independent signal.From figure it can be seen that One group of signal 10001 and 10002 is shared or public, and another set signal 10003,10006 and for all cameras 10009 be for preceding camera, the independent signal of two side cameras and corresponding LED.Among other signals, " function is connect Ground 10011 " is the common signal of all cameras and additional electronic device in endoscope.Signal "+3.3V secondary insulating " 10012, SCL_1 10013 and SDA_1 10014 is the signal for electronic device (such as memory) and power supply, these electricity Sub-device is with additional manufacturer's information, switch and switch interface etc..
Figure 101 shows other components camera shooting head plate 10015 being connected in CCD camera and video processing unit Various signals.It can be seen that having 13 CCD control signal (9 common signals, a ground signalling and 3 lists from figure Only signal -- SUB1, SUB2 and SUB3) 10016.It is imaged there are also 3 signals 10017 for LED power supply and from CCD 3 pre- video output signals 10018 of head.
Other signals (3 656 digital videos of CCIR, 3 CVBS and 3 S- videos) provide and FPGA processor, view The interface of frequency output interface and digital signal processor (DSP) and other components.For these components, with reference to Figure 90 into Explanation is gone.
Although should be noted that shared signal, it should be remembered that crucial operation limitation, to keep acceptable noise Than (SNR), and do not reduce output image quality.Referring again to Figure 90, in one embodiment, endoscopic video processing System 9020 at least sends and/or receives video output, RG, H1 and H2 signal by coaxial cable.In one embodiment, Endoscopic video processing system 9020 is sent and/or is received signal using the cable no more than 2.5mm diameter (thickness).One In a embodiment, endoscopic video processing system 9020 is sent and/or is received signal using the conducting wire not less than 46AWG, with Exempt to generate unacceptable signal-to-noise ratio.
In one embodiment, endoscopic video processing system 9020 uses the electricity for being not more than 2.06mm diameter (thickness) Cable sends and/or receives signal.In one embodiment, there are six channels using tool for endoscopic video processing system 9020 42AWG coaxial cable sends and/or receives signal.
In one embodiment, endoscopic video processing system 9020 is true according to signal number and/or bandwidth using having The cable of fixed specification sends and/or receives signal.For example, if to send and receive totally 18 independent signals, and at two Or more 9 among these signals are shared between camera, then can be used with the diameter within the scope of 2-2.5mm Cable, to realize acceptable signal-to-interference ratio and acceptable cable specification.It will be recognized by one of ordinary skill in the art that can be total to It enjoys any number of signal, including is less than 9 signals, this will lead to specific to each camera and the number of signal that generates Increase.In one embodiment, still, if shared signal is less than 6, the total meeting of to be sent and received independent signal Increase to 24, thus require cable size be more than 2.5mm or inner lead less than 46 AWG (it means that if cable size 2.5mm is remained less than, then inner lead is 42AWG, 40AWG, or the numerical value to successively decrease from it), this not only results in unacceptable Signal-to-noise ratio (SNR), also will limit the ability of the component of correct assembling (welding) circuit board.Therefore, it is described in this specification System 9020 shares signal in the best way, without reducing SNR.One aspect given this description, there are two tools In the endoscope embodiment of camera, by make specific to described two cameras each of signal number extremely Less it is 2, and the number of shared signal is made to be at least 6, it is shared can be realized optimum signal.In addition, in tool, there are three camera shootings In the endoscope embodiment of head, by make specific to three cameras each of the number of signal be at least 3 It is a, and the number of shared signal is made to be at least 6, it is shared to can be realized optimum signal.
In the endoscope embodiment using three cameras, by scheming Video Controller 9020 (such as to circuit board The electronic circuit board component 400 of 2A, 2B) send individually shared signal, then circuit board to the shared signal using one or The shared signal be changed into three independent signals by the function of multiple preprogrammings, and each signal pin is to three cameras Among one (alternatively, using two cameras endoscope embodiment in, be changed into two independent signals, each signal For one among two cameras), it can be achieved that signal is shared.It should be understood that " shared signal " is sent to (or guiding) Single destination (such as specific circuit, processor or sensor) is then divided, modulation, modifies or grasp in other ways To generate the signal of more than one same type, it is (such as different that each signal is sent to (or guiding) different destination for control Circuit, processor or sensor) signal.It should be understood that be sent to " specific to camera or the signal of sensor " or Person is oriented to single destination or is sent to another destination and being unsuitable for from single destination and is divided, modulates, repairs Change or is manipulated in other ways to generate the signal of more than one same type and each signal is sent to (or guiding) The signal of different destinations (such as different circuits, processor or sensor).In one embodiment, preprogramming Function splits received signal and amplifies, to use.In another embodiment, the function of preprogramming is to tool The specific mode of body camera carries out ratio enlargement, adjusting, segmentation or multiplication to received shared signal.In one embodiment In, in order to realize that effective signal is shared, high speed is public/it shared signal (such as H1, H2, RG) or is generated in camera shooting head plate Similar signal generate are as follows:
The impedance of signal source and the impedance matching of coaxial cable；
With compensation as caused by the factors such as cable data and imaging device (ccd sensor) mismatch and other factors The mode of disturbance is pre-formed signal in signal source；
The parameter for being pre-formed signal is stored in the onboard storage device or endoscope of camera shooting head plate；With
In camera (end of endoscope), signal distributes between imaging device.
As described above, each camera generates the independent video output signals of oneself.Then original video data is carried out Processing, to show.From the received video flowing of different cameras can on the display apparatus by side by side or it is interchangeable in a manner of it is independent Display, wherein operator can manually switch between the view from different cameras.Alternatively, controller can root These video flowings are handled according to the overlapping situation between the visual field of camera, so that it is synthesized single panoramic video Frame.In one embodiment, three outputting video streams can be displayed on three different monitors.
In one embodiment, each vision signal is independently processed from, this can improve processing speed.But this may lead Lack synchronization between the number of writing.Conventional imaging system synchronizes different cameras using frame device or memory is grabbed.But These devices are huger, the multiple cameras being not suitable in synchronous endoscopy system.In order to solve this problem, originally System described in the specification generates specific synchronization signal, to coordinate the output of ccd sensor.Therefore, implemented according to one Example, public/shared signal further include the synchronization signal for all cameras.The shared signal further includes for institute There is the clock signal of camera.The shared signal further includes the supply voltage signal for all cameras.
Figure 102 A and 102B are the block diagrams for showing example synchronization method.Figure 102 is please referred to, is described in this specification There are two main component -- DSP 10201 and CDS 10202 for the chipset tool of system.CDS 10202 includes being responsible for each CCD to take the photograph As head sensor 10203 generates the camera shooting head plate part of synchronization signal.Synchronization signal includes H1, H2 and RG (horizontal HF is synchronous), As described in above referring to Fig.1 00.DSP 10201 is handled from the received original video data of CCD camera.
When beginning, same " clock " generates common signal, and the common signal is transferred into all three cameras. That is, the signal from clock is amplified, it is used for driving circuit, and is used for while triggering remaining for being used for video processing circuits Signal.
Figure 102 B is please referred to, for synchronous video signal, H1, H2 and RG signal from CDS 10204 are ignored. On the contrary, generating synchronization signal (CLK) 10205 in digital form using FPGA.By clearly generating synchronization signal, can control Signal timing (phase), signal frequency (signal width) and signal amplitude.From the received video data of CCD 10206 by DSP 10207 processing.CLK signal phase, frequency and amplitude are adjusted so that video information by effective RG signal accurately Triggering.Adjusting CLK signal parameter allows while driving and locking the vision signal from all camera sensing devices.
Figure 103 A and 103B show a kind of for coaxial cable high speed CCD synchronization signal time delay equalization method Block diagram.Figure 103 A is please referred to, DSP 10301 generates multiple synchronization signals 10310, including is used for CCD imaging device 10303 H1, H2, RG and be used for component CDS (correlated-double-sampling) 10302 multiple signals.A function of CDS 10302 is The precoded video signal 10320 generated by CCD imaging device 10303 is sampled.In convention video camera, imaging device ( On individual plates) it is arranged near DSP and CDS, occur so that sampling enters CDS with precoded video signal in the similar time.Having In the system for having longer cable, CDS is still arranged near DSP, and still, CDS and DSP are all in the position far from imaging device.
