Pulse Train Generator
35
Pulse Train Generator
Pulse waveforms can be output from the DC IN
connector 4th/6th/7th/9th pin. Available range is 0.5Hz
to 100kHz.
Status LED
LED on the rear panel lights up according to the output
specification set for DC IN connector 4th/6th/7th/9th
pin. Various settings are possible such as assigning the
trigger signal and pulse train generator. The setting is
saved immediately and reflected at the next startup.
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.
Defect Correction
It corrects clear defect points and opaque defect points
which increase under the high/low temperature or when
exposed for a long time (seconds). From the peripheral
pixels, correction is performed on coordinate pixels in
which defects are detected. 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 18
>EXP 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.
>DEFECT-THRESHOLD 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.
