Auto Iris / Manual Iris - WolfVision VZ-C11 Bedienungsanleitung

WORKING ON THE WORKING SURFACE
SYNCHRONIZED LIGHTFIELD
If the top light of the Visualizer is used (normal working condition) a synchronized lightfield
always marks the pick-up area of the built-in camera on the working surface. The alignment of this
lightfield is made for working on the working surface.
Because of the oblique mounting of the camera and the light projector of the Visualizer, the lightfield
shifts to the right when the distance between the Visualizer and the scanned object is decreased (when
capturing high objects).
This means that the lightfield no longer exactly shows the recorded area. In this case switch off the
Visualizers top light with the LIGHT-key (#18) and work with room light.
FOCUSING
When the Visualizer is turned on the focus automatically adjusts to the
working surface level. As a result it is not necessary to readjust the focus, if you are only working with
flat material (text, photos etc.).
Due to the great depth in focus of the Visualizer, the focus rarely needs to be adjusted.
Only very high objects require a focus adjustment.
Pressing both FOCUS-keys (#19) simultaneously, activates a One-Push Auto focus.
(Please note that this is a new function, introduced in Mai 2005 with firmware Version 1.13a.
Units with older firmware perform an Auto focus for flat objects with this key combination.)

AUTO IRIS / MANUAL IRIS

WolfVision Visualizers are equipped with an auto iris. This means that the
brightness of the camera image adjusts automatically. Using the IRIS-keys (#20) the auto iris function is
switched off. In this mode the Iris can be adjusted manually. When using the ZOOM-keys (#13) the auto
iris function is switched on again. Before the iris closes completely, the Visualizer automatically dims
the light.
The standard auto iris level can be set brighter or darker in the unit's on-screen menu
- see page 9 and on-screen help.
