6. Functions and Operations

6.1. Input/Output of HD/VD Signal

6.1.1. Input of External HD/VD Signal

As factory setting the camera can be synchronized by external HD/VD signals. The signal level must be

4.0 Vp-p ± 2.0V at the input with the 75 Ohm termination ON. To change to non-terminated input, see instructions in “7. Mode Setting”.

If no ext. HD is connected, the camera will switch to the internal X-tal controlled HD.

If no ext. VD is connected, the camera will continue with its internal VD.

6.1.2. Output of Internal HD/VD Signal

The internal HD/VD output is 4.0 Vp-p from a 75 Ohm source.

To select this mode, see instructions in “7. Mode Setting”.

6.2. Normal Shutter Mode

When trigger select SW1-4 is OFF, the camera is in normal mode. The SW1-1, SW1-2 and SW1-3 are for selecting the shutter speed. The range is from OFF to 1/10,000 second in 8 steps. The camera is running continuously with an exposure as the selected shutter time.

The shutter time setting is shown in “7.1.3. Table for Shutter Time”.

6.3. External Trigger Mode

External trigger mode of CV-M300 allows 4 different driving modes, as follow.

1 Edge pre-select mode. (Asynchronous reset and exposure start by an ext. trigger)

2 Pulse width control mode. (Exposure control by the low period of the ext. trigger)

3 Start/Stop trigger mode. (Exposure start by the ext. trigger and end by the ext. VD signal)

4 Long time exposure mode. (Exposure control by the interval of the ext. VD signal)

The trigger input is AC coupled, so there is a maximum pulse width for the trigger pulse of around 60 msec. The signal level must be 4.0 Vp-p ± 2.0V. The trigger input has a fixed resistance larger than

1 kOhm and cannot be terminated with 75 Ohm by internal settings.

The following describes the details of each trigger mode.

6.3.1. Edge Pre-select Mode

The edge pre-select mode operation will only work in non-interlaced and field accumulation mode. The

CV-M300 starts the exposure (= accumulation of photoelectric charge) at the first HD pulse after the falling edge of the ext. trigger pulse. The exposure ends after the time set by the 3 shutter switches

SW1-1 to SW1-3. The range is 8 steps from OFF (1/60 or 1/50) to 1/10,000 second.

In this mode, the EEN (Exposure ENable) pulse and WEN (Write ENable) pulses are generated and output from the camera. The EEN pulse indicates the exposure time and can be used to control the illumination such as strobe light. The EEN pulse is output from pin 2 of the 6-pin multi connector. The signal level is 4.0 Vp-p from a 75 Ohm source.

The WEN pulse indicates the time period of the effective video signal output, and is useful for the timing and interfacing of external devices such as frame grabbers. The WEN pulse is output from pin 6 of the 6pin multi connector. The signal level is 4.0 Vp-p from a 75 Ohm source.

The video must be read out before a new trigger can be applied. The interval between trigger pulses must be longer than the time for 1 field + the shutter time. It is the limit for the field rate.

To use this mode

Set: SW1-4 to ON for ext. trigger shutter

SW1-5 to OFF for field accumulation

SW1-6 to ON for non-interlaced

SW1-1, 2 and 3 to shutter speed

Input: Ext. trigger to pin 5 on 6 pin multi connector.

Ext. HD to pin 6 on 12-pin multi connector. (If used).

75 Ohm termination is done with SW2-1 (HD) on PK8041 board.

Refer to Timing Chart and Cautions on next page.

Detailed switch and jumper setting is described in “7. Mode Setting”.

For connections see “5. Pin Assignment”.

Cautions in the Edge Pre-select Mode.

1. Edge pre-select mode is effective only in non-interlaced, field accumulation mode.

2. The exposure start may delay up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext. HD signal. To avoid this 1H delay and jitter, the falling edge of the trigger pulse should be synchronized with the HD pulse as shown below. It can be the ext. HD input or the Internal HD output.

6.3.2. Pulse Width Control Mode

The pulse width control mode will only work in non-interlaced field accumulation mode.

The exposure is controlled by the low period of the ext. trigger pulse. The CV-M300 starts the exposure at the first HD pulse after the falling edge of the ext. trigger pulse. The exposure ends at the first HD pulse after the rising edge of the ext. trigger. The Shutter can be controlled to be within the range from

>

1H (>64 usec.) to <60 msec. The AC coupling causes the upper limit.

EEN (Exposure ENable) pulse and WEN (Write ENable) pulses are generated and output from the camera.

The EEN pulse indicates the exposure time. The EEN pulse is output from pin 2 of the 6-pin multi connector. The signal level is 4.0 Vp-p from a 75 Ohm source.

The WEN pulse indicates the time period of the effective video signal output and is useful for the timing and interfacing of external devices such as frame grabbers. The WEN pulse is output from pin 6 of the 6pin multi connector. The signal level is 4.0 Vp-p from a 75 Ohm source

The video must be read out before a new trigger can be applied. The interval between trigger pulses must be longer than the time for 1 field + the shutter time. It is the limit for the field rate.

To use this mode

Set: SW1-1, 2 and 3 to OFF

SW1-4 to ON for ext. trigger shutter

SW1-5 to OFF for field accumulation

SW1-6 to ON for non-interlaced

Input:

JP14 on PK8042 to OPEN

Cautions in the Pulse Width Control Mode.

1. Pulse width control mode is effective only in non-interlaced field accumulation mode.

2. The exposure start may be delayed up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext. HD signal. To avoid this 1H jitter and delay, the falling edge of the ext. trigger pulse should be synchronized within 4.4 usec. to the HD pulse. It can be the ext. HD in or the Internal HD out.

See cautions in Edge Pre-select Mode page 7.

3. The voltage level of the ext. trigger has to be 4.0 Vp-p ± 2.0 V. The duration of the negative going trigger signal has to be longer than 1H = 64

µ sec. and shorter than 60 msec. The input signal is AC coupled.

6.3.3. Start/Stop Trigger Mode

The Start /Stop trigger will work in 3 modes:

1. Interlaced with frame accumulation.

2. Interlaced with field accumulation.

3. Non-interlaced with field accumulation.

The exposure time is controlled by the interval between the ext. trigger pulse and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops at the rising edge of the VD pulse. The range can be within 1/77 to 1/10,000 sec.

The Start/Stop mode is a continuous mode where the VD signal must be given continuously. It is not possible to input ext. VD randomly.

For the interlaced modes 2 ext. trigger pulses should be applied for each frame. It is one for each field.

In this way it is possible to have different exposure time for the 2 fields within an interlaced frame.

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. field 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: SW1-1, 2 and 3 to ON for 1/10,000 sec.

SW1-4 to OFF for normal shutter.

SW1-5 to ON for frame accumulation or OFF for field accumulation.

Input:

SW1-6 to OFF for 2:1 interlaced or ON for non-interlaced.

Jumper JP14 on the PK8042board SHORT.

Jumper JP7, JP11, JP12 on the PK8041 board SHORT.

Jumper JP6, JP8, JP9, JP10 on the PK8041 board OPEN.

Ext. trigger to pin 5 on 6 pin multi connector. (Cannot be 75 Ohm terminated.)

Ext. VD to pin 7 on 12 pin multi connector.

Ext. HD to pin 6 on 12 pin multi connector. (If used).

HD/VD 75 Ohm termination is done with SW2-1 and SW2-2 on PK8041 board.

Refer to Timing Chart and Cautions on next page.

Detailed switch and jumper setting is described in “7. Mode Setting”.

For connections see “5. Pin Assignment”.

- 10 -

CV-M300

Cautions in the Start/Stop Trigger Mode.

1. The input of ext. VD signal must be given continuously to synchronize with int. VD signal. It is not possible to input ext. VD signal randomly.

2. The exposure start may delay up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext. HD signal. To avoid this 1H jitter and delay, the falling edge of the ext. trigger pulse should be synchronized within 4.4 usec. to the HD pulse. It can be the ext. HD input or the internal HD output.

Shown under cautions in Edge Pre-select Mode page 7.

3. If the ext. VD input and ext. HD input are from a source with TTL level, set SW2-1 and SW2-2 on

PK8041 board OFF for non-terminated. SW2-1 for ext. HD signal, SW2-2 for ext. VD signal. See “7.2

SW2 on PK8041 Board”.

4. Each scanning mode requires the following number of external trigger pulses:

6.3.4. Long Time Exposure Mode

The Long time exposure will work in 3 modes:

1. Interlaced with field accumulation.

2. Interlaced with frame accumulation.

3. Non-interlaced with field accumulation.

The exposure time is the interval between 2 ext. VD pulses sent to the camera VD input. Each ext. VD pulse will reset and restart the internal VD in the camera as for ext. HD/VD input. So the camera is synchronized to the external HD/VD supply after each VD input.

An exposure starts after input of an external VD pulse, and ends after the next input of ext. VD, which again starts a new exposure.

The long time exposure is a continuous process where each external VD will synchronize the camera, stop an exposure, start a new exposure and read out the previous accumulated signal as interlaced or non-interlaced fields.

The exposure control can be done by feeding every N th

VD pulse from the external HD/VD supply to the camera. N is the wanted exposure time in number of fields. This is typically done in the frame grabber

PC.

The range for long time exposure is from 1 V (a single field) to

∞

. However the dark current signal will increase by longer time, so >2 seconds are not recommended at normal ambient temperature.

To use this mode:

Set: SW1-1, 2 and 3 to OFF

SW1-4 to OFF for normal shutter.

SW1-5 to ON for frame accumulation or OFF for field accumulation.

Input:

SW1-6 to OFF for 2:1 interlaced or ON for non-interlaced.

Jumper JP6 on PK8041 to SHORT

Ext. VD pulses with the exposure interval to pin 7 on 12 pin multi connector.

Ext. HD to pin 6 on 12 pin multi connector.

75 Ohm termination is done with SW2-1 and SW2-2 on PK8041 board.

The timing for the external VD interval has to be as follow. (V is the time for a single field)

Interlaced with field accumulation.

1 V or more

Interlaced with frame accumulation.

2 V or integral number of 2V

Non-interlaced with field accumulation. 2 V or more

Note: The external HD/VD sync. generator, which supply the ext. VD an HD signals should follow the scanning standard for the camera setting.

2. It is recommended not to use exposure >2 sec. since visible dark-current noise may occur.

3. Ext. HD signal (4.0 Vp-p ± 2.0V at 75 Ohm terminated) has to be input continuously

The falling edge of Ext. HD signal and Ext. VD signal are phase-synchronized.

4. Timing of ext. VD signal in each accumulation mode has to be set, as described before.

8. Adjustment of Video Signal Output Level

When an alignment of a video output signal is required, remove the camera housing and adjust potentiometers VR3, VR4 and VR5 on the PK8042 board while measuring their levels at the video output connector.

This adjustment should only be done in a setup with a standard TV test chart and controlled illumination.

VR3: To adjust the gain level of AGC. (Factory setting: 700 mVp-p ± 30 mV)

VR4: To adjust the white level. (Factory setting: 800 mVp-p ± 20 mV)

VR5: To adjust the black level. (Factory setting: 20 mVp-p ± 5 mV)

CAUTION.

Do not touch these potentiometers unless you are familiar with camera adjustments.

Location of VR3 to VR5 on PK8042 board is as follow.

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.

Even 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 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.

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

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.
