Status LED
The LED-on, blinking, or LED-off condition of the LED
on the rear panel is as follows:
Temperature Readout
Function
The camera’s internal temperature can be read from the
temperature sensor installed in the circuit board. Its
accuracy is ±2°C. Use this value as a general guide.
If the interval of the temperature sensor value is set to a
value other than 0, the temperature information can be
transmitted to a PC application as an event data.
Defect Correction
This function corrects clear defect points and opaque
defect points. From the peripheral pixels, correction is
performed on coordinate pixels in which defects are
detected. The factory setting and user setting can be
selected.
Defect correction setup procedure
1
Set conditions in which clear defect points are
prone to occur. Below is an example in which gain
is 18 dB and the shutter is 1 second. Prevent as
much light as possible from entering such as by
blocking light.
>Gain=180
>ExposureTime=1000000
2
Set the threshold in units of 14 bits. Points are
detected as clear defect points when this level is
exceeded. Below is an example for 3200 step/14bit.
Pixels that indicate 3200 to 16383 are detected.
>DefectThreshold=3200
3
Execute clear defect point detection. Detection
takes four times the EXP time setting. The output
levels on the same x coordinate axis are shown
below. The levels uniformly indicate around 1000
steps when an all-black image is taken, but defect
pixels (at high levels) are present in some locations.
All pixels whose levels exceed 3200 steps, which
was set in step 2, are detected.
Execute the detection after the image transfer is set
to off.
>AcquisitionStop
>DefectDetectionMode=1
4
Execute opaque defect point detection. Like the
clear defect point detection, set the image pickup
conditions and the threshold in units of 14 bits.
Below is an example for 10000 step/14bit. Pixels
that indicate 0 to 10000 steps are detected. If are not
setting opaque defect points, you can skip this step.
>DefectThreshold=10000
>DefectDetectionMode=2
LED-on
Power is turned on and an IP address is
set.
Blinking (low speed)
Power is turned on and an IP address is
not set.
Blinking (high speed)
Power is turned on and the reset button
is pressed down.
LED-off
Power is turned off or during startup.
Or LED-off by a user command.
