CV-A50 / CV-A60

1. General

The difference from the previous manual is that the CCD sensor in CV-A50 is changed to new types. Now the used CCD sensors are: ICX-408AL-6, 409AL-6, 418ALL-6, 419ALL-6. The CV-A50/A60 is a range of monochrome CCIR and EIA interlaced 1/2” and 1/3” CCD cameras, designed for automated application, featuring an extremely small housing and a wide range of unique functions. The asynchronous trigger can be set to work in several modes, to allow functions such as pulse width controlled shutter, programmable shutter speed and long time integration. All mode settings of the camera can be set up via an RS-232C interface, greatly reducing the need for mechanical switches of jumpers. The CV-A50 and CV-A60 output an analogue video signal, with composite sync.

6. Functions and Operations

Apart from the standard continuous operation, the CV-A50/60 features three external asynchronous trigger modes (edge pre-select, pulse width controlled and start/stop) and a special frame-delay readout mode. Long integration time mode is also supported.

6.1. Basic functions

Some of the primary camera functions need a general introduction before the operation modes are described. The list below shows the primary functions from the command list.

SM Shutter Mode Normal shutter, Programmable Exposure SH Shutter Speed Off to 1/10,000 second PE Programmable Exposure 1.5 H to 1023.5 H SC Scanning Format Interlaced, non-interlaced, (1/2 partial, 1/3 partial) TR Trigger Mode Normal, Edge, PWC, frame delay readout Long time exposure, start-stop FR Accumulation Field, Frame

The shutter SM can be set to normal (SM=0), where the exposure time is selected from 8 fixed step with the command SH, or programmable exposure (SM=1). Here the command PE allows up to 1023 steps with 1 period resolution (64 µs) for edge pre-select mode. For normal modes PE can be up to 312 for CCIR and 262 for EIA.

The scanning format SC can be selected between interlaced and non-interlaced sync signals. Further it is possible to select 1/2 and 1/3 partial scanning. It is not supported for the camera.

The accumulation FR can be field or frame. Fig. 9. show details for frame and field accumulation with shutter OFF, (left(, and shutter on, (right).

The accumulation in all trigger modes is H synchronous. The exposure will start at the first HD pulse after the trigger falling edge. Fig. 8. shows the details. In all triggered shutter modes, the shortest shutter time is limited to ≥1.5 H or 1/10,000. In trigger modes, the exposure time is not limited to the readout time. It can be longer.

6.2. Input-output of HD/VD Signals

In the default setting the camera will accept external HD/VD signals on pin 6 and 7 of the 12 pin Hirose connector. If external HD/VD is applied, the camera will synchronize to it. If no external sync signals are applied, the camera will operate with its internal x-tal controlled sync. The time requirements to the relation between VD and HD are shown in fig. 16. The input is TTL level as factory setting. It can be 75 Ohm terminated by the internal switch on the PK8277 board. SW2-1 for HD and SW2-2 for VD. On for 75 Ohm termination. To output the internal HD/VD signals on pin 6 and 7 the internal switch SW1-1 and 1-2 on the PK8277 board should be set ON. The output is TTL level from a 75-Ohm source. Refer to “7.4. Internal Switch and Jumper settings.” In trigger modes there are no continuous VD out. Only after an external trigger pulse, a VD pulse will be output.

To use this mode: Set function: SW 1 on PK8277 to IN for external VD/HD input. Factory default. SW 2 on PK8277 to 75 Ω for termination of VD/HD. SW 2 on PK8277 to TTL for TTL level for VD/HD. Factory defaults. SW 1 on PK8277 to OUT for internal VD/HD output. Input: Ext. VD in or int. VD out on pin 7 on 12-pin connector. Ext. HD in or int. HD out on pin 6 on 12-pin connector.

Important notes on using this mode

External sync system should follow the camera scanning system.

6.3. Continuous Operation (Non triggered)

For applications that do not require asynchronous external trigger (continuous operation). This is the factory default setting of the camera.

To use this mode: Set function: Trigger mode to “Normal” TR=0 Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 7 “Programmable exposure” for CCIR PE=1 through 312 “Programmable exposure” for EIA PE=1 through 262 Polarity and other functions Input: Ext. VD on pin 7 on 12-pin connector. If used. Ext. HD on pin 6 on 12-pin connector. If used.

6.4. External Trigger Modes

This camera has 5 external asynchronous trigger modes, which can be set by RS-232C commands.

1. Edge Pre-select Mode.TR=1 Pre-selected exposure. (SM=0, SM=1)

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

3. Frame Delay read out mode. TR=3 PWC exposure read out by ext. VD.

4. Long Time Exposure Mode. TR=4 Exposure is interval between ext. VD.

5. Start/stop Mode. TR=5 Exposure start by trigger and stop by ext. VD

An external trigger pulse initiates the capture (input on pin 11 of the 12-pin Hirose connector or pin 5 of the 6-pin Hirose). The leading edge of the trigger pulse initiates the exposure (this is a falling edge if factory default) and the duration of the pulse governs the exposure (accumulation) time. If the polarity of this pulse is reversed, the camera can be configured to correct for it. The duration of the external trigger pulse must be greater than 1H. It is recommended to make this longer, typically 9H.

Important notes on using trigger modes:-

The accumulation is HD synchronously accumulation. The accumulation starts at the first HD after the trigger leading edge. Shown in fig. 15. To avoid the <1H jitter caused by this delay, synchronize the external trigger to HD as shown in fig. 14. The trigger level translations should be placed inside the time A, which is 8 µseconds. Do not input a new trigger before the previous video is read out. (WEN is high).

CV-A50 / CV-A60

6.5. Edge Pre-select Mode

The leading edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by the pre-defined shutter speed set by RS-232C. The resulting video is output as “odd field” for EIA and “even field” for CCIR, and appear 9H (EIA9 or 10H (CCIR) after the leading edge of WEN (polarity is user selectable).

To use this mode: Set function: Trigger mode to “Edge Pre-select” TR=1 Accumulation to “Field” FR=0 Scanning to “Non-interlaced” SC=1 Shutter mode to “Normal” or “Programmable” SM=0, SM=1 Shutter Speed SH=0 through 7 or Programmable exposure PE=1 through 1023 Polarity for trigger and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or pin 11 on 12-pin connector). Ext. HD to pin 6 on12-pin connector. (If used).

Fig. 18. Edge pre-select EIA

Important notes on using this mode:-

• The duration of the external trigger pulse must be greater than 1H. It is recommended to make this longer, typically 9H.

• Do not input external VD signal at Pin No. 7 of the 12-pin Hirose connector, as it may

disturb the external trigger function.

- 12 -

CV-A50 / CV-A60

6.6. Pulse Width Control Mode

The leading edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by duration of the trigger pulse. The resulting video is output as “odd field” for EIA and “even field” for CCIR, and appear 9H (EIA9 or 10H (CCIR) after the leading edge of WEN (polarity is user selectable). The exposure time range is 1.5H to 1000H (shortest and longest pulse duration).

To use this mode: Set function: Trigger mode to “Pulse Width Control” TR=2 Accumulation to “Field” FR=0 Scanning to “Non-interlaced” SC=1 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or pin 11 on 12 pin connector). Ext HD to pin 6 on 12 pin connector. (If used)

Important notes on using this mode:-

• Do not input external VD signal at Pin No. 7 of the 12-pin Hirose connector, as it may

disturb the external trigger function.

CV-A50 / CV-A60

6.7. Frame-delay read out Mode

This mode allows simultaneous capture of multiple camera using a common external trigger pulse subsequent multiplexed (sequential) readout using a single input frame grabber, as the user has control over when the image is read out from the CCD sensor. The exposure starts at the falling edge of the ext. trigger signal, and ends at the rising edge of the ext. trigger signal. (In the same way as Pulse Width Control mode). The captured image is now stored in the CCD until an ext. VD signal is given to the camera. The resulting video is output as “odd field” for EIA and “even field” for CCIR, and appear 9H (EIA9 or 10H (CCIR) after the leading edge of WEN (polarity is user selectable). To use this mode: Set function: Trigger mode to “Frame delay read-out” TR=3 Accumulation to “Field” FR=0 Scanning to “Non-interlaced” SC=1 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or pin 11 on 12 pin connector). Ext. VD to pin 7 on 12 pin connector. Ext HD to pin 6 on 12 pin connector. (If used)

Fig. 21. Frame delay read-out. CCIR

Fig. 22. Frame delay read out. EIA

Important notes on using this mode:-

•

The readout delay time must not exceed 2 seconds. This is because visible dark current noise may appear on the video signal due to the long time exposure of the CCD image sensor.

•

It is recommended to use a strobe light (e.g. LEDs or Xenon tube. High light levels during the delay time can disturb the image. The EEN signal can be used to trigger a strobe light

•

See Fig. 16 for the phase relationship between ext. HD and ext. VD pulses

- 14 -

CV-A50 / CV-A60

6.8. Long Time Exposure Mode

The exposure time is the interval between 2 ext. VD pulses sent to the VD input of the camera (Pin No. 7 of the 12-pin Hirose connector). The exposure starts after input of the first ext. VD pulse, and ends after the next input of the next ext. VD pulse, which again starts a new exposure. The long time exposure is a continuous process where each external VD will synchronize the camera, stop on exposure, start a new exposure and read out the previous accumulated signal. The exposure time can be selected in intervals of complete vertical timing periods (525H for EIA and 625H for CCIR).

To use this mode: Set function: Trigger mode to “Long time exposure” TR=4 Accumulation to “Field” or “Frame” FR=0, F=1 Scanning to “Interlaced” SC=0 Shutter to “OFF” SH=0 Polarity and other functions Input: Ext. VD to pin 7 on 12 pin connector. Ext HD to pin 6 on 12 pin connector.

Fig. 23. Long time exposure. Field accumulation.

Fig. 24. Long time exposure. Frame accumulation.

Important notes on using this mode:-

•

Exposure time range is 1/30 sec. to ∞. However, it is recommended not to use exposure over

2.0 sec. This is because visible dark current noise may appear on the video signal due to the

long time exposure of the CCD image sensor.

•

Ext. HD signal (TTL 2.0~5.0V) has to be input continuously.

•

See Fig. 16 for the phase relationship between ext. HD and ext. VD pulses

•

The EEN pulse is not provided when using this mode.

- 15 -

CV-A50 / CV-A60

6.9. Start/Stop Mode

The exposure time is controlled by the interval between the ext. trigger and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops 14.5 H after the falling edge of the VD pulse. It means that the trigger pulse must be applied after the external VD pulse, for exposures less than 14.5 H. The range can be between 1/60 to 1/10,000 for EIA, and 1/50 to 1/10,000 for CCIR. The Start/Stop mode is a continuous mode where the VD signal must be given continuously. It is not possible to input external VD randomly. The difference between interlaced frame accumulation or field accumulation can be explained as follow. Both modes have 2 fields output in an interlaced frame. With frame accumulation, the contents in the ODD and EVEN sync fields will come from sensing field 1 and 2 on the CCD sensor. With field accumulation both ODD and EVEN sync fields will contain the signal from sensing field 1 and 2 added together. Non-interlaced with field accumulation needs only 1 trigger pulse for each field.

To use this mode: Set function: Trigger mode to “Start/Stop” TR=5 Accumulation to “Field” or “Frame” FR=0, F=1 Scanning to “Interlaced” SC=0 Polarity and other functions Input: Ext. VD to pin 7 on 12 pin connector. Ext HD to pin 6 on 12 pin connector.

Important notes on using this mode:-

• As the start of exposure will be synchronized with the internal H signal, the start of exposure may be shifted by max 1H.

• To avoid this shift (jitter), synchronize the camera with an external HD and make sure that the trigger pulse aligns to the HD signal as shown in Fig. 14.

• For exposures <14 H, the trigger pulse is after the extern VD pulse. Fig. 26

7.4. Internal Switch and Jumper Settings.

7.4.1 HD/VD input-output selection

In the default setting the camera will accept external HD/VD signals on pins 6 and 7 of the 12 pin Hirose connector. The composite video signal from the camera will be synchronized to an external HD/VD source connected to the camera. TTL level (between 2 and 5 V).

To set up the camera to output HD/VD signals on pins 6 and 7 on the Hirose connector follow these steps. See fig. 29.

1. Switch off the power to the camera.

2. Remove the camera cover, by removing the 5 screws.

3. Locate switches SW1-1 and SW1-2 on the PK8277 circuit board, and set both in the ON

position.

Note: The HD/VD output source is 75 Ohm.

7.4.2. Selecting termination of HD/VD input signals

The default setting of the HD/VD input is high impedance TTL. The camera expects to get a signal that swings between 2 and 5 volts. This setting allows the largest number of camera to be synchronized from a single HD/VD source (such as another camera or a frame grabber). Under certain circumstances it may be necessary to terminate the HD/VD input, in order to match the impedance of the signal source, to eliminate over/undershoot or standing waves in the signal.

To change the HD/VD input to 75Ohm terminated, follow these steps

1. Switch off the power to the camera.

2. Remove the camera cover, by removing the 6 screws.

3. Locate switches SW2-1 and SW2-2 on the PK8277 circuit board, and set the according

both in the ON position.

10.1. CV-A50 or CV-A60 emulating CV-M50 interfacing

The CV-A50 and CV-A60 have a slightly different pin configuration on the 12-pin Hirose connector, compared to the M-series. This new configuration is compliant to the EIA-J standard. This means, however, that the CV-A50 and CV-A60 are not completely backward compatible with the CV-M50, CV-M300, etc in all cases (depending on the cable configuration). This application note gives detailed instruction on how to change the pin configuration, by changing internal solder jumpers. Please note: Only a qualified electronics technician or engineer should make these changes.

10.3. CV-A50/60 without sync on video output.

For applications where the video output signal should be without the composite sync signal, it is possible to remove the sync signal by removing an internal resistor. Remove the top cover and the bracket for holding boards. The resistor is found on the main board. (Mother board). The resistor, which is very small, can then carefully be removed with a small solder iron.

10.4. 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.

10.5. Typical CCD Characteristics

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

V. Smear

Due to an excessive bright object such as electric lighting, sun or strong reflection, vertical smear may be visible on the video monitor screen. This phenomenon is related to the characteristics of the Interline Transfer System employed in the CCD.

V. Aliasing

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

Blemishes

Some pixel defects can occur, but this does not have an effect on the practical operation.

Patterned Noise

When the CCD camera captures a dark object at high temperature or is used for long time integration, fixed pattern noise (shown as white dots) may appear on the video monitor screen.
