USAGE PRECAUTIONS Handle carefully
Do not drop the equipment or allow it to be subject to strong impact or vibration, as such action may
cause malfunctions. Further, do not damage the connection cable, since this may cause wire
breakage.
 Environmental operating conditions
Do not use the product in locations where the ambient temperature or humidity exceeds the
specifications.
Otherwise, image quality may be degraded or internal components may be adversely affected. In
particular, do not use the product in areas exposed to direct sunlight.
 Combination of C-mount lens
Depending on the lens you use, the performance of the camera may not be brought out fully due tothe deterioration in resolution and brightness in the peripheral area, occurrence of a ghost,aberration and others. When you check the combination between the lens and camera, be sure to
use the lens you actually use.
When installing a lens in the camera, make sure carefully that it is not tilted.
In addition, use a mounting screw free from defects and dirt. Otherwise, the camera may be unable
to be removed.
As for the C-mount lens used combining this product, the projection distance from bottom of thescrew should use 10mm or less.
Bottom ofthe screw

C-mount lens

10mm or less

 Mounting to a pedestal
When mounting this product to a pedestal, make sure carefully that the lens doesn't touch with thepedestal.
 Do not expose the camera’s image-pickup-plane to sunlight or other intense light directly.
Its inner CMOS sensor might be damaged.
 Occurrence of moiré
If you shoot thin stripe patterns, moiré patterns (interference fringes) may appear. This is not a
malfunction.
 Occurrence of noise on the screen
If an intense magnetic or electromagnetic field is generated near the camera or connection cable,
noise may be generated on the screen. If this occurs, move the camera or the cable.

USAGE PRECAUTIONS Handling of the protective cap
If the camera is not in use, attach the lens cap to the camera to protect the image pickup surface.
 If the equipment is not to be used for a long duration
Turn off power to the camera for safety.
 Maintenance
Turn off power to the equipment and wipe it with a dry cloth.
If it becomes severely contaminated, gently wipe the affected areas with a soft cloth dampened withdiluted neutral detergent. Never use alcohol, benzene, thinner, or other chemicals because suchchemicals may damage or discolor the paint and indications.
If the image pickup surface becomes dusty, contaminated, or scratched, consult your sales
representative.
 Disposal
When disposing of the camera, it may be necessary to disassemble it into separate parts, inaccordance with the laws and regulations of your country and/or municipality concerning
environmental contamination.

“This symbol is applicable for EU member states only”[Phenomena specific to CMOS sensor]
Defective pixels

A CMOS image sensor is composed of photo sensor pixels in a square grid array. Due tothe characteristics of CMOS image sensors, over- or under-driving of the pixels results in
temporary white or black areas (as if these are noises) appearing on the screen. Thisphenomenon, which is not a defect is exacerbated under higher temperatures and longexposure time.
Image shading
The brightness of the upper part of the screen may be different from that of the lower part. Notethat this is a characteristic of a CMOS image sensor and is not a fault.

Functions

5.1

Gain

The variable range of gain is -6 to +18dB.
Notes on gain setting:Setting the gain value too high increases noises. When you adjust the brightness of the image, I ask
you to have final image quality checked with your environment.
5.2

Black Level

Black level is adjustable from -25% to +25% as white saturation level is 100%.
5.3

Gamma

Gamma correction curve is adjustable from 0.45 to 1.
5.4

LUT (Look up Table)

Arbitrary curve and binarization are possible by using 10 bit input and 10 bit output LUT.
5.5

Exposure Time

Manual exposure time control is available. Exposure time is adjustable by the internal sync signal.
5.6White balance

Color models have two white balance modes, manual white balance (MWB) and one-push auto whitebalance (OPWB). Select the mode to suit the subject and purpose.
5.6.1 MWB
R/B gain can be set independently.
5.6.2 OPWB
When OPWB is executed, the camera adjusts R/B gain automatically.

An image is captured at the desired timing using trigger signal input. External trigger signal fromtrigger input connector and software trigger from control command via the USB 3.0 interface areavailable (Edge mode / Bulk mode). Trigger polarity is selectable (High active / Low active).
Note that Random Trigger Shutter will cause a delay between trigger signal and start of exposure.
See 7. Timing Chart for detail.
- Edge mode (TriggerSequence0)
The exposure time is determined by Exposure Time setting.

Notes on Random Trigger Shutter mode:- In the period when FRAME_TRIGGER_WAIT signal is inactive, user must not input external trigger
signal to this camera.
- When the interval of the input trigger signal is extremely short, or when the trigger signal is noisy,
there is a possibility of causing the malfunction. In this case, please input a proper trigger signal.
