Working with
subarrays
Using different Live
and Snapshot
resolutions
Observing low
contrast samples
Observing highly
reflecting samples
Observing high
contrast samples
Acquiring images with
a long exposure time
Accessing USB data
storage devices
Acquiring only a part of the image (subarray)
does not increase the frame rate, because the
OLYMPUS LC30 does not support the so-called
hardware clipping.
If Live and Snapshot resolutions differ,
measurements performed on the Live image
may be slightly displaced on the Snapshot
image (max. 2 pixels).
When observing a low contrast sample or alter-
natively a highly reflecting one, a so-called spot
flare may be noticeable, if the AS diaphragm is
almost completely closed.
High contrast samples may cause the auto
exposure to fail, resulting in an underexposed
image.
When acquiring images with a long exposure
time (e.g. > 200 ms), an increasing amount of
hot pixels may become visible.
When attaching, removing or accessing USB
data storage devices, for example an external
hard drive, while the image acquisition is in
progress, a temporary drop in frame rate might
be observed.
3 System environment
No countermeasure
available.
Use identical resolutions for
Live and Snapshot when
performing measurements.
Switch on the shading correc-
tion or decrease illumination
intensity and open the AS
diaphragm.
In the Camera Control of the
software, define an exposure
compensation. Alternatively,
switch to manual exposure
mode.
No countermeasure
available. This phenomenon
is common to all camera
sensors and not caused by a
failure of the equipment.
Only use or access USB
devices when no image
acquisition is in progress.
