Typical CCD Characteristics

The following effects may be observed on the video monitor screen do not indicate any fault of

the CCD camera, but do associate with typical CCD characteristics.

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 Interline Transfer System employed in the CCD.

When the CCD camera shoots a dark object at high temperature, fixed pattern noise

(dots) may be appeared over the entire area of the video monitor screen.

a) Input of External HD/VD signal (Factory Pre-set)

Video output of CV-M90(rev.c) in factory pre-set mode can be

synchronized with external HD/VD signal (4.0Vp-p ± 2.0V at 75

ΩΩ

Ω

terminated) .

For TTL level input (2.0 ~ 5.0V), set SW301 switch located on

PK8088 board to OFF position.

For more information, see ”5. Pin Assignment” and ”7. Mode Set-

ting”.

b) Output of Internal HD/VD signal

To output internal HD/VD signal (4.0Vp-p at 75

ΩΩ

Ω Non-terminated),

make the jumpers JP306/309 to short-circuited and JP305/308 to

open-circuited.

Each jumpers are located on PK8088 board inside the camera.

For more information, see ”5. Pin Assignment” and ”7. Mode

Setting”.

Note: Internal HD/VD signal output is 75 W impedance.

External trigger mode of CV-M90(rev.C) allows 3 different driving

modes, as follows.

a) Random Trigger Mode – 1 (Asynchronous reset/Exposure control by ext. trigger

and 7- step fixed shutter)

b) Random Trigger Mode – 2 (Exposure control by ext. trlgger and Ext. VD signal)

c) Long Time Exposure Mode (Exposure control by ext. VD signal)

Followings are the details of each triggering modes.

6-2. External Trigger Mode

a) Random Trigger Mode - 1

In Random Trigger Mode-1 (only in Non-interlaced, field

accumulation mode), CV-M90(rev.c) starts an exposure

(=accumulation of electric charge) at the falling edge of ext.

trigger pulse and ends the exposure according to the time set by

shutter (7-step fixed shutter speed), and outputs the accumulated

signal in one-field (odd-field in EIA and even-field in CCIR).

In this mode 1, EEN (Exposure ENable) pulse and WEN (Write

ENable) pulse are generated and output from the camera.

EEN pulse (4.0Vp-p at 75

ΩΩ

Ω non-terminated) indicates the

exposure time set by shutter, and it is useful to control the

duration time of lighting such as stroboscopic-light and harogen-

light. EEN pulse is output from pin no.4 of 6P Multi connector.

(See 5. Pin Assignment)

WEN pulse (4.0Vp-p at 75

ΩΩ

Ω non-terminated) is indicating the

duration time of effective video signal output, and it is useful to

set a timing with frame gabber and other image processing

equipment. WEN pulse is output from pin no.6 of 6P Multi

connector and pin no.7 of D-SUB 9pin connector. (See 5. Pin

Assignment)

To use random trigger mode, make following procedure.

1. Set SW1-4 switch on rear panel at ON position, to change

shutter function into Ext. Trigger Shutter Mode.

2. Check SW301A switch if it is set at OFF position tor Field

accumulation mode.

SW301 switch is located on PK8088 board.

3. Set SW1-5 on rear panel at ON position, to change Scanning

system into Non-interlace mode.

4. Set SW1-1, SW1-2 and SW1-3 on rear panel for optimum

shutter speed selection.

5. Input ext. trigger pulse (TTL: 2.0V ~ 5.0V) at pin no.5 of 6P

Multi connector.

6. Refer to the following ”Timing Charts”, and also to ”Caution

on Random Trigger Mode-1” .

7. For more information, see ”5. Pin Assignment” and ”7. Mode

Setting”.

- 9 -

1. Random trigger mode-1 is effective only at Non-interlaced, field

accumulation mode.

2. 1H jitter max. may occur when ext. trigger and Int. HD signals are not

synchronized each other. Therefore, It is recommended to make phase-

synchronization between ext. trigger pulse and int. HD slgnal, in order to

eliminate such jitter.

3. Input terminal of ext. trigger is set at TTL, by factory pre-set.

Caution on Random Trigger Mode-1

b) Random Trigger Mode - 2

- 10 -

In this mode-2, the exposure time of shutter can be controlled

within a range of 1/77 ~ 1/10,000sec. by a duration between ext.

trigger pulse and ext. VD signal. CV-M90(rev.c) starts the

exposure (=accumulation of electric charge) at falling edge of

ext. triggerpulse and ends the exposure after input of ext. VD

signal. The accumulated signal can be output directly after the

exposure in field/frame accumulation mode by 2:1 interlaced

scanning mode and field accumulation mode by Non-interlace

mode.

To use this mode-2, make the following procedure.

1. Make jumpers JP301 located on PK8088 board short-

circuited.

2. Shutter speed must be set at 1/10,000sec. by SW1.

1) Set SW1-4 on rear panel at OFF position for Normal

Shutter mode.

2) Set SW1-1, SW1-2 and SW1-3 on rear panel at ON

position for 1/10,000sec. speed.

3. Set SW301-4 switch on PK8088 board for CCD accumulation

at optimum position either OFF for Field accum. mode or ON

for Frame accum. mode.

4. Set SW1-5 on rear panel switch for scanning system at

optimum position either OFF for 2:1 Interlace mode or ON

for Non-interlace mode.

5. Input ext. trigger pulse (TTL level: 2.0V ~ 5.0V) at pin no.5

oF 6P Multi connector, and input ext. VD signal (4.0Vp-p ±

2.0V at 75

ΩΩ

Ω terminated) at pin no.7 of 12P Multi connector.

Ext. VD signal must be input continuously and it has to be

synchronized with Ext. HD signal.

6. It is necessary to change the input-time of ext. trigger pulse

according to scanning mode, as follows.

- 2:1 Interface mode - > 2-time pulse inputs

- Non-interlace mode - > 1-time pulse input

7. Refer to the following ”Timing Charts”, and also to ”Caution

on Random Trigger Mode-2”.

8. For more information, see ”5. Pin Assignment” and ”7. Mode

Setting”.

- 11 -

1. As 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

”at random”.

2. Exposure-start may deiay up to 1H max., when the falling edge of ext.

trigger pulse is not synchronized with the falling edge of ext. HD signal.

Therefore, it is recommended to make phase-synchronization between ext.

trigger pulse and ext. HD signal.

3. Ext. trigger input has to be TTL level (2.0 ~ 5.0V).

4. If ext. HD/VD signal have TTL level (2.0V ~ 5.0V), set SW301-1and SW301-2

located on PK8088 board at OFF position. Refer to ”7. Mode Setting”.

Caution on Random Trigger Mode-2

c) Long Time Exposure Mode

- 12 -

In Long Time Exposure mode, the exposure time of shutter can

be controlled by a duration of ext. VD signal input.

CV-M90(rev.C) starts the exposure (=accumulation of electric

charge) after input of ext. VD signal, and ends the exposure

after the next input of ext. VD signal. The accumulated video

signal in one full frame (ODD/EVEN or EVEN/ODD) by 2:1

interlace mode can be output directly after every 2nd input of

ext. VD signal. Also the accumulated video signal in one field

(ODD or EVEN) either by 2:1 or Non-interlaced mode can be

output directly after every 2nd of input ext. VD signal.

To use Long time exposure mode, make the following procedure.

1. Make jumpers JP302 on PK8088 board short-circuited.

2. Set SW1-1, -2 and -3 on rear panel at OFF position.

3. Check SW1-4 on rear panel switch if it is set at OFF position

for normal shutter mode.

4. Set SW301 switch located on PK8088 board, for CCD

accumulation at optimum position either OFF for Field

accum. mode or ON for Frame accum. mode.

5. Set-SW1-5 on rear panel switch for scanning system at

optimum position either OFF for 2:1 Interlace mode or ON

for Non-interlace mode.

6. Input ext. VD signal (4.0Vp-p ± 2.0V at 75 Q terminated) at

pin no.7 of 12P Multi connector.

7. Timing of ext. VD signal in each accumulation mode has to

be set, as follow.

- 2:1 Interlace mode (Field accum. mode) : 1VD or more

- 2:1 Interlace mode (Frame accum. mode) : 2VD or Integral time of 2VD

- Non-interface made (Field occum. mode) : 2VD or more

Note:

1VD In 2:1 Interlace = 262.5H in EIA, 312.5H In CCIR

2VD in 2:1 Interlace = 525.0H in EIA, 625.0H in CCIR

2VD in Non-Interlace = 524.0H in EIA, 624.0H in CCIR

8. Refer to the following ”Timing Charts”, and also to ”Caution

on Long Time Exposure Mode”.

9. For more information, see ”5. Pin Assignment” and ”7. Mode

Setting”.

1. Theoretical exposure time of shutter in each TV standard is as follows.

EIA : 1/30sec.

− ∞− ∞

− ∞

CCIR : 1/25sec

− ∞− ∞

− ∞

However, It is recommended to moke exposure not more than 2sec. since

visible dark-current nolse may occur on video signal due to the long time

exposure on CCD Image sensor.

2. Do not Input Ext. VD signal at pln no. of

6P Multi connector.
