4.1 Image recorder
Overview
The INVIZ imaging recorder fulfils the
following additional functions beside the
visualization of the inspection image:
:: Adjustment of the light intensity of
INVIZ endoscopes and pushing cameras
- Mostly endoscopy is done with full
light intensity, since all INVIZ cameras
control the brightness of the picture via
the exposure time of the camera itself.
Only under few circumstances, it can be
advisable to control the light intensity
manually (e.g. strongly reflecting surface).
:: Adjustment of the rotational speed of
the option motorized side view.
:: Recording and showing of individual
images on conventional CF card.
:: Recording and showing of video scenes
on conventional high speed CF card
with up to 25/30 images per second.
:: Administration of the image and video
data (saving, copying, renaming and
deletion).
The INVIZ imaging recorder can be operated
with all
INVIZ camera systems, irrespective
of the video standard (PAL or NTSC). As a
rule, the video signal made available is
detected automatically and reliably. With
further accessories, the imaging system
can be used even for the camera techno-
logy of other manufacturers.
The control pendant can be operated
easily through the intuitive menu guidance
on the display screen and the keys can be
operated even with gloves or protective
gear.
The CF card shaft is hidden, in order to
protect it from mechanical influences or
inadvertent removal of the card. At the
same time, the imaging recorder ought to
be protected from collisions or falls, in
order to prevent damage.
The imaging recorder ought to be regular-
ly cleaned with a soft cloth, cotton bud
and 70% isopropanol. Never use aggressi-
ve solvent (Acetone)!

In the menu guidance, there are functions
which may not be relevant for your
INVIZ
system. In order to ensure that the
image recorder possesses the greatest
possible compatibility with many devices,
these sub-functions were, however, not
removed.
viZaar is always improving or extending
the existing software of the
image recorder. This can, however, have
the result that sub-areas of the function
description of the imaging recorder do
not immediately correspond to the
instructions.
