1. Precautions
1.1. Handling Precautions
□Do not use or store camera in dusty or humid places.
□Do not apply excessive force or static electricity that could damage camera. Handle camera with care.
□Do not shoot direct images that are extremely bright (e.g., light source, sun, etc.). When extremely strong light source
is shot, smear or blooming may occur. When camera is not in use, please put the lens cap on.
□Follow the instructions in Chapter 3.3. “External Connector Pin Assignment”for connecting camera. Improper
connection may cause damages not only to the camera but also to the connected devices.
□Confirm mutual ground potential carefully and connect camera to monitors or computers. AC leak from the connected
devices may cause damages or destroy the camera.
□Do not apply excessive voltage. (Use only the specified voltage.) Unstable or improper power supply voltage may
cause damages or malfunction of the camera.
Our warranty does not apply to damages or defects caused by irregular and/or abnormal use of the
product.
1.2. Restrictions on Applications
□The camera must not be used for any nuclear equipment or aerospace equipment with which mechanical failure or
malfunction could result in serious bodily injury or loss of human life.
□The camera must not be used under conditions or environments other than those specified in this manual.
□Usage of VCC-SXCXP1SW for military related purposes is prohibited by List Controls for Export Trade Control Order.
1.3. Disclaimers (Exception Clause)
CIS should not be liable for any damages or losses if;
□damages or losses are caused by earthquake, lightning strike, fire, flood, or other acts of God.
□damages or losses are caused by deliberate or accidental misuse by user, or failure to observe information and
instructions explained in this manual.
□damages or losses are caused by repair or modification conducted by user or any unauthorized party.
1.4. Image Quality Limitations
VCC-SXCXP1SW is a SWIR camera. Usage of SWIR sensor makes image quality characteristics of this model different
from those using normal silicon image sensors.
Please refer to “Appendix: VCC-SXCXP1SW Points to note on image quality characteristics” for details.

The following formula calculate framerateaccording to “Pixel format”, “ROI (height)”, and “Exposure time with ClockSync”.
①For internal sync mode (free run mode), H sync (LineSync) mode
Frame rate = 1,000,000/{Tline[us] x (Height + 36)} [fps]
②For internal sync mode (free run mode), CLK sync (ClockSync) mode
Frame rate = 1,000,000/{Tline[us] x (Height + 46) + Exposure time[us] - 7.372[us]} [fps]

4.11. Restrictions on Timing for Trigger Pulse Input
□With LineSync mode, user can input a trigger for the next frame while camera is reading out signals. However, do
not input a trigger pulse to end exposure while camera is reading out signals. In other words, a trigger pulse to start
reading out signals for the next frame before completion of reading out signals for the prior frame is restricted.

4.12. Fixed Trigger Shutter Mode H Sync. Trigger (LineSync)

□This is a mode to start exposure with external trigger input and expose for a period set by Exposure Time.
□Trigger operation is H sync. V-sync. reset.
□Delay time (Exposure Time Delay) from detecting the trigger edge in camera to actually starting exposure is
1H~2H.
□Since external trigger signals synchronize with camera internal H signals, 1H jitter occurs to Exposure Time Delay.
□Input a trigger pulse with more than 1H width. For time of 1H, please refer to Section 4.7 for details.
□There is an exposure time period for approx. 7.372μs at the trailing edge of Exposure output.
□Camera accepts triggers while outputting video images. However, do not input any trigger signals to start outputting
the next video before completion of prior video output.
□Camera ignores trigger input during exposure time. (Refer to (A) in the drawing below). Do not use any trigger
cycle shorter than 1 frame.

□Trigger operation is CLK sync. V-sync. reset. Delay time (Exposure Time Delay) from detecting the trigger edge in
camera to actually starting exposure is approx. 0.13μs. Input a pulse with more than 1μs width as a trigger.
□There is an exposure time period for approx. 7.372μs at the trailing edge of Exposure output.

4.14. Pulse Width Trigger Shutter Mode H Sync. Trigger (LineSync)
(TriggerMode=On, SensorSyncMode=LineSync, TriggerActivation=LevelHigh)
□This is a mode to start exposure with external trigger input and expose for a period of pulse width.
□Trigger operation is H sync. V-sync. reset.
Delay time (Exposure Time Delay ①) from detecting the trigger edge in camera to actually starting exposure is
1H~2H. Delay time (Exposure Time Delay ②) from detecting the end edge in camera to actually end exposure is
1H~2H＋7.372μs.
□Since external trigger signals synchronize with camera internal H cycle, approx. 1H jitter occurs to Exposure Time
Delay ①and ②. With pulse width trigger mode, jitters may occur for both exposure start edge and exposure end
edge. Exposure time changes and flicker may become noticeable, especially with high-speed shutter setting. Fixed
trigger shutter mode might eliminate those flickers. However, synchronizing trigger pulse with camera H cycle (LVAL)
to input will solve this problem.
□Functionally, there is no upper limitation, but noises such as dark noise shadings may become noticeable with long
time exposure. Please note that increase of white defective pixels is inevitable with this image sensor.
□There is an exposure time period for approx. 7.372μs at the trailing edge of Exposure output.
□Camera ignores trigger input during exposure time. Do not use any trigger cycle shorter than 1 frame.
□Camera accepts triggers while outputting video images. However, do not input any trigger signals to start outputting
the next video before completion of prior video output. (Refer to (A) in the drawing below)

(TriggerMode=On, SensorSyncMode=ClockSync, TriggerActivation=LevelHigh)
□This is a mode to start exposure with external trigger input and expose for a period of pulse width.
□Trigger operation is CLK sync. V-sync. reset.
Delay time (Exposure Time Delay ①) from detecting the trigger edge in camera to actually starting exposure is
Approx. 0.13μs. Delay time (Exposure Time Delay ②) from detecting the end edge in camera to actually end
exposure is approx. 7.372μs.
□Pulse width 2.628μs (Min.) ~ approx. 2 frames
Functionally, there is no upper limitation, but noises such as dark noise shadings may become noticeable with long
time exposure. Please note that increase of white defective pixels is inevitable with this image sensor.
□There is an exposure time period for approx. 7.372µs at the trailing edge of Exposure output.
