Chapter 6 Troubleshooting

Symptom Possible cause Action
Color reproducibility is not
good.
The color temperature of the
illumination is improper.
Adjust the illumination of the optical device so that the
subject is seen in the right color.
The illumination is too bright or too
dark.
Adjust brightness of the illumination properly.
Adjust the exposure.
The white balance is not set properly.
Obtain the white balance under the same conditions
as for the observation and micrography.
The setting of the camera gain is too
high.
Adjust the camera gain properly.
Note: Refer to the instruction manual of the
NIS-Elements.
The image adjustment is improper.
Set the saturation, hue, contrast, black level, etc. to
an appropriate level.
Note: Refer to the instruction manual of the
NIS-Elements.
Monitor is not properly adjusted.
Adjust the display quality of the monitor properly.
Note: Refer to the instruction manual of the monitor.
The image quality is rough. The camera gain is set too high.
Set the illumination brightness, the camera gain, and
the exposure time to an appropriate level.
Note: Image capturing with high camera gain may
result in a noisy image (with texture,
unevenness, unwanted lines). Lower the
camera gain setting if such a problem occurs.
Note: Refer to the instruction manual of the
NIS-Elements for adjustment of the camera
gain and exposure time.
The image is distorted.
The subject was moving during image
acquisition.
Stop the movement of the subject.
Note: When you move the XY stage right and left,
etc., for image acquisition, the resulted image
may look distorted. This is not a hardware
failure: a distortion-free image can be acquired
once the subject movement is stopped.
Image flickers or horizontal line
noises appear on the image.
A fluorescent or sodium vapor lamp is
used for illumination.
Change the illumination types or set a longer
exposure time.
Note: Fluorescent or sodium vapor lamp flickers at a
high-speed. This causes flickering or horizontal
line noises on an image, which can be
minimized by setting a longer exposure time.
Note: Refer to the instruction manual of the
NIS-Elements for adjustment of the exposure
time.
