USAGE PRECAUTIONS
⚫Life expectancy of CMOS sensors
Unlike other products, the CMOS sensor used in this product is not a CMOS sensor for industrial
equipment. Please note that the life of the CMOS sensor may be shortened depending on the
operating conditions of the camera (ambient temperature, heat radiation conditions, etc.).
⚫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 to
the 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 the
screw should use 8mm or less.
8mm or less

⚫Mounting to a pedestal
When mounting this product to a pedestal, make sure carefully that the lens doesn't touch with the
pedestal.
⚫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 with
diluted neutral detergent. Never use alcohol, benzene, thinner, or other chemicals because such
chemicals 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, in
accordance with the laws and regulations of your country and/or municipality concerning
environmental contamination.
[Phenomena specific to CMOS sensor]
“This symbol is applicable for EU member states only”
⚫Defective pixels
A CMOS image sensor is composed of photo sensor pixels in a square grid array. Due to
the 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. This
phenomenon, which is not a defect is exacerbated under higher temperatures and long
exposure time.
⚫Image shading
The brightness of the upper part of the screen may be different from that of the lower part. Note
that this is a characteristic of a CMOS image sensor and is not a fault.

5.12 Random Trigger Shutter
An image is captured at the desired timing using trigger signal input. External trigger signal from
trigger input connector and software trigger from control command via USB 3.1 Gen1 interface are
available (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. In random shutter mode, the camera operates with global reset.
Operates with rolling shutter during binning.
- Edge mode: TriggerSequence0
Exposure of all the lines is simultaneously started in the timing of a trigger input.
The exposure time of first line is the manual set value of the electronic shutter.

Notes on Random Trigger Shutter :
- In the period when FrameTriggerWait 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.

5.17 Scalable
Scalable is to read out arbitrary area of the image. Only single rectangle is selectable. Concave or
convex shape is impossible. The number of selectable window is only one.
- Window size: {A+4*m (H)} * {B+2*n (V)}
A, B = minimum unit size
m, n = integer
The window size is equal or less than maximum image size.
- Start address: {4*i (H)} * {2*j (V)}
i, j = integer
The window size is equal or less than maximum image size.

5.18 Binning
It supports the binning feature that the CMOS sensor has. The luminance of the neighbor pixels in
horizontal/vertical are weighted, added and averaged. This feature achieves higher frame rate and
improves S/N ratio. The maximum frame rate varies as follows.

Notes on Defect pixel correction when binning is used :
This product enables the defective pixel correction feature at factory setting after registering
the X-Y coordinates of defective pixels in all-pixels scan mode. At the binning mode, the defective
pixels will be possible to appear in unexpected coordinates by the weighted addition of the CMOS
sensor. Please take measure to add the coordinates for defective pixel correction if it is problem.
