Status LED
The status indicated by the LED (lit, blinking, not lit) on
the rear panel is as follows: You can change whether
LEDs are lit or not with a user command.
Lit
Power supply is applied. Ready for operation.
Blinking
Power supply is applied. Connected by USB 2.0.
Off
Power supply is not available, or the power
supply is connected but not turned on. Or the
LED was turned off by a user command.

Function
The camera's internal temperature can be read from a
temperature sensor mounted on the module board. Its
accuracy is ±2 °C. Use this value as a general guide.

Defect Correction
This function corrects for white defect pixels and black
defect pixels. A correction is applied for defective pixels
by interpolating from the peripheral pixels surrounding
the detected defect. The factory setting and user setting
can be selected.

Defect correction setup procedure
1
Set conditions in which white defect points are
easier to detect. Below is an example in which the
gain is 18 dB and the shutter is 1 second. Prevent as
much light as possible from entering by blocking
light.
> Gain = 18
> ExposureTime = 1000000

2
Set the threshold in units of 14 bits. White defect
points are detected when this level is exceeded.
Below is an example for 3200 steps/14 bits. Pixels in
the range 3200 to 16383 are detected.
> DefectThreshold = 3200
3
Execute white defect point detection. Detection
takes four times the EXP time setting. The output
levels for the same X coordinate are shown below.
The display is uniformly black around step 1000 for
an all-black image, but defect pixels (at high levels)
are present in some locations. All pixels whose level
exceed the step 3200 threshold set in step 2 are
detected.
> DefectDetectionMode = DetectWhitePixels
Defect pixel
4
Execute black defect point detection. Like the white
defect point detection, set the image pickup
conditions and the threshold in units of 14 bits.
Below is an example for 10000 steps/14 bits. Pixels
from step 0 to step 10000 are detected. If not setting
black defect points, you can skip this step.
> DefectThreshold = 10000
> DefectDetectionMode = DetectBlackPixels
Read the status to determine whether the detection is
finished.
> DefectDetectionMode (readout)
DetectBlackPixels (executing)
Off (exit)
The value Off is returned when finished.
