Possible cause
The color temperature of the
illumination is improper.
The illumination is too bright or too
dark.
The white balance is not set properly.
The setting of the camera gain is too
high.
The image adjustment is improper.
Monitor is not properly adjusted.
The camera gain is set too high.
The subject was moving during image
acquisition.
A fluorescent or sodium vapor lamp is
used for illumination.
Possible cause
A product failure has occurred.
Troubleshooting
Adjust the illumination of the optical device so that the
subject is seen in the right color.
Adjust brightness of the illumination properly.
Adjust the exposure.
Obtain the white balance under the same conditions
as for the observation and micrography.
Adjust the camera gain properly.
Note: Refer to the instruction manual of the
NIS-Elements.
Set the saturation, hue, contrast, black level, etc. to
an appropriate level.
Note: Refer to the instruction manual of the
NIS-Elements.
Adjust the display quality of the monitor properly.
Note: Refer to the instruction manual of the monitor.
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.
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.
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.
