Now referring again to Figure 90, it should be appreciated that come from multiple camera shootings in order to provide rapidly and to doctor in real time The simultaneous display of head should handle before display and synchronize the image data for coming from each camera sensing device in real time.This It 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, described in this specification Video processing architecture supports three major functions：
A) signal transmission and the control that each camera is realized in a manner of most preferably shared resource need to lead to reduce The sum for crossing the signal of cable transmission, to obtain using smaller/thinner cable progress signal transmission while still ensure that high letter Make an uproar than ability；
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 proactive using one As the embodiment of head and two side cameras, conventional processing system for video needs to transmit 36 independent signals, wherein each Camera has 12 associated signals, including 11 control signals and 1 video backhaul signals.Similarly, for adopting With the embodiment of two cameras (such as a preceding camera and a side camera, or only there are two side cameras), often The processing system for video of rule needs to transmit 24 independent signals.In one embodiment, in order to effectively operate camera simultaneously Vision signal is received 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 voltages (15V)
9.VL- supply voltages (- 7.5V)
10.SUB- substrate clocks
11.LED- light-emitting diodes tube voltages
12.Vout- video output signals
13. ground connection
Although ground signalling is public, to camera circuit board (such as the electronic circuit board component of Fig. 2A, 2B 400) it transmits and receives its of 36 signals (each among three cameras needs 12 signals) from camera circuit board It is about the cable of 3mm that remaining signal, which needs diameter, could realize acceptable signal-to-interference ratio, it is contemplated that limited in endoscope end Space, this size are too big.Vision signal can be caused to have unacceptable high noisy using the smaller cable of diameter.
Referring again to Figure 90, embodiment described herein can utilize small diameter cable (that is, about 2.5mm or 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 board Processing is instructed with providing required concrete signal for each camera.This allows system to control all necessary signals, without Use 36 different signals.Although moreover, it will be recognized by one of ordinary skill in the art that in disclosed Video Controller 9020 The signal processing of detailed description is to illustrate for the endoscope embodiment using three observation elements, but it is applied equally to make With the embodiment of two observation elements.
In one embodiment, preceding nine control signals (V01, V02, V03, V04, H01, H02, RG, VDD and VL) pass through Signal is detached in circuit board (such as electronic circuit board component 400 of Fig. 2A, 2B) in the optics end of endoscope 9010 simultaneously It taps in camera head and is shared between camera.Remaining signal is not shared.For example, SUB signals are taken the photograph for each As head is specific, because they are used for " shutter control ".Therefore, in this embodiment, system, which is three cameras, makes With independent SUB1, SUB2 and SUB3 signal.In addition, independently and respectively to the LED circuit power supply for illumination.Therefore, exist In this embodiment, it is useful for three signals -- LED1, LED2 and LED3 of LED supply voltages.Since nine signals are altogether It enjoys, therefore the sum for operating the signal needed for three cameras is reduced from 36 to 18, including three individual videos are defeated Go out signal.Therefore, disclosed Video Controller 9020 generate multiple signals specific to each camera/observation element, with And multiple shared signals of each camera/observation element are non-specific for, to reduce the sum for the signal for needing to transmit.
Figure 100 is the shared signal for listing each camera in detail and the table of independent signal.It can be seen that one from figure Group 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 connects Ground 10011 " is the common signal of all cameras and additional electronic device in endoscope.Signal "+3.3V secondary insulatings " 10012, SCL_110013 and SDA_110014 is the signal for electronic device (such as memory) and power supply, these electronics dress It sets 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 controls signals (9 common signals, a ground signalling and 3 independent letters from figure Number -- SUB1, SUB2 and SUB3) 10016.It is also useful for 3 signals 10017 of LED power supplies and comes from the 3 of CCD camera A pre- video output signals 10018.
Other signals (3 656 digital videos of CCIR, 3 CVBS and 3 S- videos) provide and FPGA processor, video The interface of output interface and digital signal processor (DSP) and other components.For these components, carried out with reference to Figure 90 Explanation.
Although should be noted that shared signal, it should be remembered that crucial operation limitation, to keep acceptable signal-to-interference ratio (SNR), and output image quality is not reduced.Referring again to Figure 90, in one embodiment, endoscopic video processing system 9020 are at least sent and/or are received video output, RG, H1 and H2 signal by coaxial cable.In one embodiment, endoscope Processing system for video 9020 is sent and/or is received signal using the cable no more than 2.5mm diameters (thickness).In one embodiment In, endoscopic video processing system 9020 is sent and/or is received signal using the conducting wire not less than 46AWG, in case generating can not The signal-to-noise ratio of receiving.
In one embodiment, endoscopic video processing system 9020 uses the cable no more than 2.06mm diameters (thickness) Send and/or receive signal.In one embodiment, there are six channels using tool for endoscopic video processing system 9020 42AWG coaxial cables send and/or receive 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 the electricity with the diameter within the scope of 2-2.5mm can be used Cable, to realize acceptable signal-to-interference ratio and acceptable cable specification.Appoint it will be recognized by one of ordinary skill in the art that can share The signal for number of anticipating, including is less than 9 signals, this can cause specific to each camera and the number of signal that generates increases. In one embodiment, still, if shared signal is less than 6, the sum of to be sent and reception independent signal can increase to 24, thus it is more than that 2.5mm or inner lead are less than 46AWG (if it means that cable size remains less than to require cable size 2.5mm, then inner lead is 42AWG, 40AWG, or the numerical value that successively decreases from it), this not only results in unacceptable signal-to-noise ratio (SNR), the ability of the component of correct assembling (welding) circuit board can also be limited.Therefore, the system 9020 described in this specification with Best mode shares signal, without reducing SNR.One side given this description, in tool, there are two cameras In endoscope embodiment, it is at least 2 by making the number specific to the signal of each among described two cameras, and So that the number of shared signal is at least 6, can realize that optimum signal is shared.In addition, in tool, there are three the endoscopes of camera In embodiment, it is at least 3 by making the number specific to the signal of each among three cameras, and make to share The number of signal is at least 6, can realize that optimum signal is shared.
In the endoscope embodiment using three cameras, by making Video Controller 9020 (such as scheme 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 function of multiple preprogrammings the shared signal is changed into three independent signals, three cameras of each signal pin pair it In one (alternatively, using two cameras endoscope embodiment in, be changed into two independent signals, each signal pin To one among two cameras), it can be achieved that signal is shared.It should be understood that " shared signal " is sent to (or guiding) list A destination (such as specific circuit, processor or sensor) and then divided, modulation, modification manipulate 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 Circuit, processor or sensor) signal.It should be understood that be sent to " specific to camera or the signal of sensor " or It is oriented to single destination or is sent to another destination and being unsuitable for from single destination and be divided, modulate, change Or the signal and each signal manipulated in other ways to generate more than one same type is sent to (or guiding) difference Destination (such as different circuits, processor or sensor) signal.In one embodiment, the function of preprogramming is torn open Point received signal is simultaneously amplified, to use.In another embodiment, the function of preprogramming is with to specific camera Specific mode carries out ratio enlargement, adjusting, segmentation or multiplication to the shared signal of reception.In one embodiment, for reality Now effective signal is shared, high speed public/shared signal (such as H1, H2, RG) or the similar signal that is generated in imaging head plate It is produced as：
The impedance of signal source and the impedance matching of coaxial cable；
It is disturbed caused by the factors such as cable data and imaging device (ccd sensor) mismatch and other factors with compensation Dynamic mode 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.The video flowing received from 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 for coming 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 this A little devices are huger, the multiple cameras being not suitable in synchronous endoscopy system.In order to solve the problems, such as this, this explanation System described in book generates specific synchronizing signal, to coordinate the output of ccd sensor.Therefore, described according to one embodiment Public/shared signal further includes the synchronizing signal for all cameras.The shared signal further includes being used for all cameras Clock signal.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.02 is please referred to Fig.1, the system described in this specification Chipset tool there are two critical piece -- DSP 10201 and CDS 10202.CDS 10202 includes being responsible for each CCD camera shootings Head sensor 10203 generates the camera plate part of synchronizing signal.Synchronizing signal includes H1, H2 and RG (horizontal HF is synchronous), such as Described in Figure 100.The original video data that the processing of DSP 10201 is received from CCD camera.
When beginning, same " clock " generates common signal, and the common signal is transferred into all three cameras. That is, the signal for coming from clock is amplified, it is used for driving circuit, and is used for while triggering remaining letter for video processing circuits Number.
02B is please referred to Fig.1, for synchronous video signal, H1, H2 and RG signal for coming from CDS 10204 are ignored.Phase Instead, synchronizing signal (CLK) 10205 is generated in digital form using FPGA.By clearly generating synchronizing signal, signal can control Periodically (phase), signal frequency (signal width) and signal amplitude.The video data received from CCD 10206 is by DSP 10207 Processing.CLK signal phase, frequency and amplitude are adjusted so that video information is accurately triggered by effective RG signals.It adjusts Section CLK signal parameter allows while driving and locking the vision signal for coming from all camera sensing devices.
Figure 103 A and 103B show a kind of for coaxial cable high speed CCD synchronizing signal time delay equalization methods Block diagram.03A is please referred to Fig.1, DSP 10301 generates multiple synchronizing signals 10310, includes for CCD imaging devices 10303 H1, H2, RG and the multiple signals for being used for component CDS (correlated-double-sampling) 10302.A function of CDS 10302 be to by The precoded video signal 10320 that CCD imaging devices 10303 generate samples.In convention video camera, imaging device is (in monolithic On plate) it is arranged near DSP and CDS, occur in the similar time to which sampling enters CDS with precoded video signal.With compared with In the system of long cable, CDS is still arranged near DSP, and still, CDS and DSP are all in the position far from imaging device.Therefore, Precoded video signal has delay when entering CDS.In addition, when high-speed synchronous signal (such as H1, H2, RG signal) is by long cable transmission Generate delay.In order to compensate for this delay, in one embodiment, system has additional component 10304,10305 and 10306, as shown in Figure 103 B.Referring now to Figure 103 B, these components generate high speed signal H1*, H2*, RG*10330, and make It uses and comes from original signal H1, H2, RG10340 of DSP 10307 as basic signal.In one embodiment, component 10304 Code 10350 is generated in FPGA, and for the structure of high speed signal.According to the type of endoscope, 10350 use of code comes from In the parameter of memory 10308, and it include the signal value of random time point.In one embodiment, component 10304 is modulation Device, adapter or converter, according to the type of endoscope, the modulator, adapter or converter are based on coming from memory 10308 data/parameter changes original signal.Code 10350 enter analog-digital converter 10305, and be converted into H1, H2, The similar pulses 10330 of RG, but pass through pre-shaped, it is interfered with compensating cable.Amplifier and resistance are reached from 10305 signals of ADC Anti- matching element 10306.
Therefore, the processing system for video described in this specification has also combined cable compensation method.Ordinary skill people Member is it should be understood that different types of endoscopy device has different cable lengths on endoscope.By controlling synchronous letter Number so that all three CCD obtain expected signal from one side, can compensate for the variation of cable length.This be by follow with it is upper Similar process described in text is come what is completed, and by the process, the timing of synchronizing signal and amplitude are adjusted.Therefore, for Different timings and amplitude is arranged in each cable length.Moreover, this mechanism can also come from the feedback of CCD simultaneously by " sensing " Parameter appropriate is adjusted accordingly to execute automatically.
