5.4 Input and Output Circuits

In the following schematic diagrams show the input and output circuits for video and timing signals.

5.4.1 Iris video output

This signal can be used for lens iris control in Continuous mode.

The signal is taken from the CCD sensor output before the gain circuit. The video output is without sync. The signal is 0.7 Vpp from 75Ω without termination. Do not use auto shutter (CCD iris) when auto iris lens is used.

5.4.1 (b) Trigger input

• The trigger input is available from either pin #11 on the 12 pin connector or pin #5 on the 6 pin con-

nector.

• These inputs are internally connected, do not

use simultaneously.

• The input is AC coupled. To allow a long pulse

duration, the input circuit is a flip-flop. When it is toggled the negative or positive differentiated spikes are caused by the falling or rising trigger edges.

• The trigger polarity can be changed by TP=1.

• Trigger input level is 4 V ±2 V. It can be termi-

nated by SW301.1: ON for 75Ω. OFF for TTL.

5.4.1 (c) XEEN output

CV-M71A

FIGURE 7.Trigger input.

• XEEN is located on pin #9 of the 12-pin

connector. This signal is active during the accumulation (exposure) period of the camera.

• The output circuit is 75 Ω complementary

emitter followers. It will deliver a full 5 volt signal.

• Output level > 4 V from 75 Ω. (No termina-

tion).

6 Functions and Operations

6.1 Basic functions

The CV-M71A camera is a progressive scan camera with a primary color mosaic CCD (Bayer). An internal DSP performs the color-interpolation, outputting separate analog R, G and B signals through the 9-pin D-sub connector.

An analog iris video signal can be used for lens iris control.

There are four modes; continuous, edge pre-select (EPS), pulse width control (PWC) and sensor gate control. The accumulation can be HD synchronous or HD asynchronous. For trigger modes using fast shutter times, smearless read out is possible.

CV-M71A

6.1.1 Sensor Gate Control

This function is for applications where a strobe flash is the only illumination, and where the exact time to fire the strobe is unknown. This allows the strobe to fire in a time window that can include up to several frames. The resulting video readout can also be delayed by this function. This makes the synchronization of the frame grabber more flexible.

FIGURE 9.Sensor Gate Control

The Sensor Gate Control signal inhibits the internal SG signal so accumulation can continue. The SG signal is an internal signal, which is low when the accumulated charge on the photo diode array is transferred to the vertical ccd registers for readout. When the Sensor Gate Control input is high, the internal SG pulse is inhibited, and the signal accumulation on the photo diode array can take place. After the strobe flash is fired, the Sensor Gate Control signal can be low. The resulting video is then read out after the first VD (or SG), following the falling edge of Sensor Gate Control signal.

6.1.2 CV-M71A Test pattern

The CV-M71A camera has a build in color bar generator. When it is activated, the output image is a test pattern as shown in the figure. The RGB values shown are for an 8-bit output.

The test pattern displays when the output select command is OS=3.

6.3 Input/Output of Timing Signals

For switch settings, refer to chapter “7.1. Switch setting by internal switch.”

6.3.1 Input of External HD/VD signals

External synchronization is only possible in continuous mode. For trigger modes only external HD can be input.

HD and VD input pins on D-sub 9-pin connector are shared with HD/VD output (HD/VD inputs are factory default). HD/VD inputs are also available by means of the Hirose 12-pin connector. SW302.1 selects by means of the D-sub 9-pin or Hirose 12-pin for HD input. SW303.1 selects by means of the D-sub 9-pin or Hirose 12-pin for VD input. The video output is synchronized with external HD/VD signals if applied. If no external HD is connected, the camera will switch to the internal X-tal controlled HD sync. If no external VD is connected, the camera will continue with its internal VD.

The tracking range for H is 37.50 KHz ±1%

The external HD/VD signal should be 4.0 Vp-p ±2.0 V from a 75 Ω source. Factory setting is TTL. For 75 Ω termination is SW301.3 for HD input and SW301.4 for VD; input should be ON.

Figure 15. through figure 18. shows timing details for external sync operations.

Set function: SW302.1 for HD input ON: D-sub 9-pin, OFF: Hirose 12-pin

Important notes on using this mode:

• External sync system should follow the camera scanning system

• The ext. HD/VD phase relations should follow the synchronization shown in Figure 15.

FIGURE 18.HD timing details

Note: The pulse width of Ext. HD requires between 48clk to 166clk. HD can not be reset directly.

6.3.2 Input of external trigger

The external trigger signal can be by means of pin 5 on the 6-pin connector (TI=0) or pin 11 on the 12-pin connector. (TI=1). Here it should be 4.0 Vp-p ±2.0 V from a 75 Ω source.

The factory setting is TTL. For 75 Ω termination SW301.1 should be ON.

6.3.3 Output of XEEN

The XEEN signal is 4.0 Vp-p from a 75 Ω source.

6.3.4 Output of HD/VD signals

HD input and VD input of D-sub 9-pin can be changed to HD and VD outputs by selecting internal switches, SW302 and SW303. The output level is 4 V p-p.

6.4 Operation Modes

This camera can operate in four primary modes.

1. TR=0 Continuous Mode. Pre-selected exposure.

2. TR=1 Edge Pre-select Mode. Pre-selected exposure.

3. TR=2 Pulse Width Control Mode. Pulse width controlled exposure.

4. TR=3 Sensor Gate Control Strobe illuminated exposure with delayed read out

The triggered shutter in EPS and PWC mode can be HD synchronous or HD asynchronous accumulation. Refer to Section 6.4.1 on page 14 and Section 6.4.2 on page 16.

-13-

Page 16

CV-M71A

To avoid <1H time jitter in HD synchronous mode, it is recommended the trigger be synchronized to the HD as shown in Figure 19. If trigger transitions are inside the limits shaded blue, the accumulation jitter is minimal.

FIGURE 19.Trigger to ext. HD phase relation

In the following chapters the different operation modes and functions are covered.

6.4.1 HD synchronous accumulation

With LS=0, the accumulation will start synchronously with HD. The trigger pulse should be longer than 2 H, and the accumulation will then start at the first HD after the trigger leading edge. The exposure start delay is shown in the table below the timing drawings.

In EPS mode the exposure stops 0.5H after the selected shutter time, (in number of HD).

In PWC mode the exposure stops 4.3μs after the trigger trailing edge. It results in up to 1 H jitter.

In trigger modes with HD synchronous accumulation, a new exposure can be started while the previous frame is read out. The new exposure should not finish before the frame is read out. FVAL shall be low for >2 LVAL. The maximum frame rate in trigger modes can then be close to the frame rate in continuous mode.

Important notes on using this mode:

• In HD synchronous trigger modes, exposure jitter up to 1 H can be the result, if the trigger trailing

edge is not synchronized to HD.

• The minimum trigger interval in EPS should be longer than (1 V + 2 H), and 1V + 4H) in PWC.

6.4.2 HD asynchronous accumulation

With LS=1, the accumulation starts after the trigger leading edge.

•

• The exposure start delay is fixed. See the table included in Figure 22 for the fixed delay.

• In EPS mode the exposure stops 0.5 H after the selected shutter time, (in number of HD).

• In PWC mode the exposure stops 0.5 H after the trigger trailing edge.

• A new trigger must not be applied before the previous frame is read out (VD is low).

• The minimum trigger interval should be longer than (exposure time + 1 V + 3 H).

Note: In HD asynchronous trigger modes, there is a fixed delay but no exposure jitter.

• For timing details, refer to Figure 12 on page 8 and Figure 13 on page 9

6.4.4 Edge Pre-select Trigger Mode

An external trigger pulse initiates the capture. The exposure time (accumulation time) is the fixed shutter speed set by SH or PE. The accumulation can be HD synchronous or HD asynchronous. The exposure start delay is shown in the table below the timing drawing. The resulting video signal will start to be read out after the

selected shutter time. To avoid up to 1LVAL time jitter in HD synchronous accumulation, it is recommended to synchronize the trigger to HD (see Figure 19 on page 14). Use HD synchronous accumulation (LS=0) for the highest trigger rate. A new exposure can be started while the previous is read out. The shutter time should end >2 LVAL after FVAL goes low. For timing details, refer to Figure 12 on page 8, Figure 13 on page 9 and Figure 24 on page 19.

6.4.5 Pulse Width Control Trigger Mode

In this mode the accumulation time is equal to the trigger pulse width. Here it is possible to have long time exposure. The maximum recommended time is <120 frames. The accumulation can be HD synchronous or HD asynchronous. The exposure start delay is shown below the timing drawing. To avoid up to 1LVAL time jitter in HD synchronous accumulation, it is recommended to synchronize the trigger to HD. (See fig. 18.). Use LVAL synchronous accumulation (LS=0) for highest trigger rate. Here a new exposure can be started while the previous is read out. The trigger pulse should end >2 LVAL after FVAL goes low.

The resulting video signal will start to be read out after the trigger rising edge. For timing details, refer to fig. 12. through fig. 13. and fig. 24.

6.4.5 (a) Sensor Gate Control

This mode is for applications with strobe flash illuminations or long time accumulations up to several frames. In this mode the camera runs continuously. The external Sensor Gate control signal will disable the internal XSG pulse so the accumulation continues during the next frame. The resulting video is read out after the first VD (or SG), following the trailing edge of the Sensor Gate Control signal.

-20-

Page 23

CV-M71A

To inhibit the internal XSG pulse and continue the accumulation, the external sensor gate control signal should be low during line 28, where the internal XSG is placed. Refer to Figure 27 on page 21. The sensor gate control signal can be synchronized by the VD signal. For video out timing details, refer to Figure 12 on page 8, Figure 13 on page 9, Figure 25 on page 20 and Figure 27 on page 21.

6.5 Other Functions.

Smearless readout. SL=1.

This function reduces the unwanted smear signal from a highlighted scene when a short exposure time is used. It works in EPS and PWC modes, but a dummy readout is performed before the active accumulation is started. It will remove the smear above the highlighted parts in the image, but there is still smear left below highlighted areas.

The trigger leading edge will start the dummy readout. It takes 86 lines before the exposure starts. The exposure stops and the resulting video signal is read out. Smearless readout will only work with HD synchronous accumulation.

Shutter mode. SM=0, SM=1 and SM=2. SH=0 through SH=14 and PE=0 through PE=628.

• Shutter mode is available in Continuous mode and EPS mode.

• With SM=0 this function selects the shutter from the 15 fixed steps (SH).

• With SM=1 from programmable in 628 steps (PE).

• SM=2 is auto shutter. The auto shutter range is from OFF to 1/25,000. The reference setting for auto

shutter is accomplished using the command AG=, which is common with the AGC. Together with the AGC function it keeps the video output constant over a wide range of illumination. Auto shutter will work in continuous mode. (TR=0).

• Do not use auto iris lens with the auto shutter function. This may make the camera unstable.

Trigger polarity. TP=0, TP=1.

The default trigger polarity is active low (falling edge) (TP=0). It can be inverted to active high (TP=1).

Gamma. GS=0, GS=1

For CV-M71A, gamma is selectable between 0.45 (GS=1) and 1.0 (GS=0). Factory default is 1.0.

Gain settings. AS=0, AS=1.

The video gain can be selected between manual gain (AS=0), or AGC (AS=1). Manual gain is set by the master gain level command GA=. The reference level for the AGC is set by the AGC reference level AG=1 through AG=255. In AGC mode the video level is kept constant by the automatic gain control circuit within a 12 dB range. Together with the auto shutter function it keeps the video output constant over a wide range of illumination. For continuous mode only.

Master gain level. GA=-50 through +150.

This gain setting works on all three colors. GA=0 is 0dB gain, which is the normal working point. The range is from -3 dB to +12 dB.

Red gain level: GAR=-1024 through +2047.

Blue gain level: GAB=-1024 through +2047.

Red and blue gain level is used for manual white balance of the RGB output signal. Range -6dB to +6dB.

-22-

Page 25

CV-M71A

Master black level. BL=0 through BL=255.

Black level (or set-up level) sets the video level for black on all three colors.

Factory setting is 32 LSB for 10-bit or 8 LSB for 8-bit.

Red black level. BLR=-128 through +127.

Blue black level. BLB=-128 through +127.

These settings are used for fine adjustment of the black level for red and blue.

White Balance. WB=0 through WB=3.

Here the white balance mode is selected. There are three fixed values, 3200K, 4600K and 5600K. The manual range is from 2800K to 7000K. One-push 2800K to 6500K. Manual/one-push WB=0 makes it possible to use red and blue gain level to manually adjust the white balance. The one-push white balance function AW=0 and the button on the camera rear is active here.

One-push auto white balance. AW=0.

When this command is received, an automatic white balance is performed. Range 2800K to 6500K. The result can be seen when the command inquire result of WB is sent. AWRS?

Inquire result of WB. AWRS?

After a one-push white balance is done, the result can be called with this command. Returned error code 0 is busy; 1 is success; 2 is green is too bright; 3 is green is too dark; 4 is a time-out error.

Output select. OS=0 , OS=3

With OS=0, the video output is the analog RGB signal. With OS=3 the test pattern is output (Refer to “CV-M71A Test pattern” on page 6).

Iris video output.

The iris video output on the 4-pin of the 12-pin Hirose is 700 mv for 100% video out. The iris video signal is taken before the gain circuit. It is without sync.

The iris video signal can be used for auto iris lens drive in continuous mode.

Do not use the auto shutter (CCD iris) function together with an auto iris lens. It may result in an unstable regulation.

8 Camera Control Tool for CV-M71A

The Camera Control Tool for Windows NT/2000/XP can be downloaded from www.jai.com. The control tool contains a camera control program and tools for making your own program.

For the integrator and experienced user, the Camera Control Tool is much more than a program with a Windows interface. It also provides an easy and efficient ActiveX interface built for MS Windows NT, 2000 and XP. The OCX interface has the ability to connect to the camera using the serial interface of the PC by reading and writing properties for the camera. This integration requires simple programming skills with Visual Basic, Visual C++ or similar languages in a Microsoft Windows environment.

8.1 Control Tool Windows

-31-

Page 34

CV-M71A

8.2 Camera Control Tool Interface

The Camera Control Tool Software is based on a main Tool Bar and a number of associated Tool Windows. Each button in the Tool Bar opens a separate Tool Window when selected. The layout of the program can be adjusted by arranging the windows the way it is preferred. The program will store this information and recreate this layout when the program is restarted. All Camera Control Tools have a Communication Window and an About Window. The other window(s) contains camera control commands.

The About Window

The about window contains a picture of the camera and information about the program version, Internet connection to JAI A/S and access to the help documents. The List box that contains the help documents will list all files, which have the extension .pdf and that are found in the program (default) folder C:\Program Files\JAI A-S\’Control Tool Name’ It is possible to download updated operation manuals from the JAI website: http://www.jai.com/camera/manuals.asp/sprog=uk

For newer camera models the About window also shows Model Name, Camera ID and User ID. It is possible to edit and save free text in User ID.

At the bottom of the windows (except the Communication Window) is a colored bar. The bar is green when the Camera Control Tool is connected to a camera and the camera is turned on. The bar is red when the Camera Control Tool is not connected to a camera or when the camera is turned off.

The Communication Window

The Communication Window is used to connect the Camera Control Tool with the JAI camera. Depending on the camera there are two possible ways to communicate with a JAI camera.

RS-232: Select the communication port, where the serial cable is connected from the list box in the ‘Communication Port’ field, or click the ‘Auto’ button to search for a camera on communication port 1 to 16. The camera control program automatically sends a camera request on every communication port. The user is prompted to use a communication port if a camera answers the request.

-32-

Page 35

CV-M71A

RS-232 communication:

1. Select ‘COM-ports’ from the ‘CL Manufacturer/COM-ports’ list box.

2. Select the communication port where the serial cable is connected to the camera

from the ‘Serial Port’ list box or click the ‘Auto’ button to search for a camera on communication port 1 to 16.

The Serial Port list box and the Auto search button are only active when COM-ports is selected.

Auto search

Click the auto button to search for a camera on communication port 1 to 16. The camera control program automatically sends camera request on every communication port. The user is prompted to use a communication port if a camera answers the request.

This button is only used for RS-232 communication.

Off/On-line mode

The Camera Control Tool Application can run Off-line (without a camera attached) and all functions are fully functional in offline mode. Off-line mode is indicated in The Communication Window, where a status field with graphic and text indicates the on/off-line status. Changing the selected communication port (from the communication window) changes the on-line/ off-line status. If a camera is found on the selected communication port the application runs on-line otherwise off-line.

Changing the settings in the application will automatically update the camera settings when the application is online. If the application looses connection with the camera it will automatically go to off-line mode. The changed status is indicated in the communication window.

Synchronize program and camera

The Camera Control software has the ability to synchronize either the camera or the program. Click ‘Synchronize camera’ to write all settings from the program to the camera or click the ‘Synchronize program’ to load all settings from the camera to the program.

Files

When clicking the ‘Write to File’ or ‘Read from File’ button, the user is prompted for a file using a standard file dialog. New files are created if they do not already exist.

Files for camera settings have the extension cam. Information about the communication port is not stored in the files. All settings are automatically sent to the camera when a file has been loaded (if the camera is online).

Factory and User Settings

Use the Store button to store the current camera settings into the user settings area in EEPROM. Current camera settings are not saved when the camera is turned off. To save current camera settings you have to save them on the available user areas.

CV-M71A

3. It is possible to work with the Camera Control Tool whether the camera is online or offline.

4. The newer JAI cameras always start up with the last used user area (but for some old models it will start up with the last saved user area.)

5. The Camera Control Tool saves the last used settings (not the user area), which do not have to be the same as for the last saved user area.

6. The setup file ‘CameraName.ini’ stores all information about camera settings. When the program is started the last settings for the program are loaded from the file ‘CameraName.ini’.

7. When you turn on the camera and the Camera Control Tool, it is possible that the Camera Control Tool does not show the actual camera settings (see 4. and 5.).

aTo obtain the camera settings click Synchronize Program.

bTo send the settings saved in the Camera Control Tool (last used settings) to the cam-

era click Synchronize Camera.

cTo see which area the camera has started up in click Get.

11 Appendix

11.1 Precautions

•

Personnel not trained in dealing with similar electronic devices should not service this camera.

• The camera contains components sensitive to electrostatic discharge. The handling of these devices

should follow the requirements of electrostatic sensitive components.

• Do not attempt to disassemble this camera.

• Do not expose this camera to rain or moisture.

• Do not face this camera towards the sun, extreme bright light or light reflecting objects.

• When this camera is not in use, put the supplied lens cap on the lens mount.

• Handle this camera with the maximum care.

• Operate this camera only from the type of power source indicated on the camera.

• Power off the camera during any modification such as changes of jumper and switch setting.

11.2 Typical Sensor Characteristics

The following effects may be observed on the video monitor screen. They do not indicate any fault of the camera, but do associate with typical sensor characteristics.

V. Ali a sin g

When the CCD camera captures stripes, straight lines or similar sharp patterns, a jagged image may appear on the monitor.

Blemishes

• Some pixel defects can occur, but this does not have a practical effect on the camera’s operation.

• No CCD spots are visible when cameras are shipped.

• In general, photo diodes comprising a CCD sensor can be damaged by cosmic rays and as a result,

spots may appear on the CCD sensor.

• Please use care not to expose the camera to cosmic rays during storage and transportation.

• We recommend sea shipment instead of air transport due to the strong influence of cosmic rays on

the camera.

• Pixel defects may be exaggerated depending on ambient temperature and/or camera settings such

as gain up or long term exposure, and accordingly, the camera should be used within the specifications.

Patterned Noise

When the sensor captures a dark object at high temperature or is used for long time integration, fixed pattern noise may appear on the video monitor screen.

Caution when installing the lens on the camera

When the lens is installed to the camera, floating dust may be attached to the surface of the lens or CCD of the camera. The Lens cap and the camera cap should be kept on until installation. The work should be done in a clean environment. When installing, the surface of the camera should be downward so that dust does not get into and stick to the lens. Be careful not to touch the surface of the lens.

Exportation

When exporting this product, follow the export regulations of your country.
