Auto Iris / Manual Iris - WolfVision EYE-12 Bedienungsanleitung

Autofocus
Please note that objects with very low contrast e.g. a blank sheet of paper) are difficult to focus. If the
autofocus does not work just move the object slightly.
For special applications the autofocus can also be switched off using the on/off switch (#24). The autofocus
is also switched off when the manual FOCUS keys (#27) are used.
Digital Zoom
Please note that the EYE-12 has an optical 12x zoom. The digital 4x zoom increases the overall zoom
range to a 48x zoom. When you zoom in further than the optical zoom range, the digital zoom is
automatically activated. However, please be aware that when the digital zoom is used, the resolution of the
picture is not as good as before.
The default setting displays a message on-screen when you are in the digital zoom mode.
Still pictures in the memory can also be digitally zoomed.
You can change the behavior of the EYE-12 in the digital zoom mode in the on-screen menu
(see page 10).

Auto Iris / Manual Iris

The EYE-12 is equipped with an auto iris function. That means that the brightness of the camera image
adjusts automatically. When using the IRIS-keys (#26) the auto iris function is switched off. In this mode the
iris can be adjusted manually. When using the ZOOM-keys (#20) the auto iris is switched on again.
The auto iris also controls the Auto Gain and Auto Shutter to extend the iris-range.
The auto iris priority can be switched off in the on-screen menu. ("Auto iris priority" means when pressing
the ZOOM-keys, the auto iris switches on.)
The overall brightness level can be set lower or higher in the on-screen menu with "Image Brightness" (see
page 10). The optimal setting depends on the connected display device.
Shutter Control
The shutter extends the iris-range if the iris is fully mechanically closed.
There is the possibility of adjusting the exposure time in fine steps e.g. for scanning computer monitors.
FLICKERLESS (default) prevents flickering of the image.
The behaviour of the SHUTTER can be changed in the on-screen menu.
