Cautions about visual image acquisition :
The following phenomena may be observed when the G100/G120 acquires
or saves a visual image. These phenomena are not failures.
(1) The color of the visual image periodically changes.
(2) The color of the visual image may be different from the real target object
when the image is replayed in FREEZE.
To avoid such phenomena, perform image acquisitions by changing the
RUN/FREEZE timing or camera angle. In this case, it is recommended
to acquire visual images with observing the image on the screen.
The following phenomena may be observed in the outdoor data acquisition.
Such phenomena are not caused by camera failures.
(3) If the contrast is great (e.g. because of backlight), the object may appear
darker on the camera display compared to the brightness of the background.
To avoid these phenomena, control the frame so that it covers only
target object.
(4) If the bright sunlight enters the visual camera, entire picture may become
reddish.
To avoid these phenomena, shield the camera from bright sunlight.
