AUTO FOCUS / MANUAL FOCUS
Please note that objects with very low contrast (like a blank sheet of paper) are difficult to focus. If the auto
focus does not work, just move the object slightly.
For special applications the auto focus can also be switched off, using the AF key (#18) The auto focus is
also switched off when the manual FOCUS keys (#15) are used.
The auto focus priority can be switched off in the on-screen menu. ("Auto focus priority" means that
pressing the ZOOM-keys switches the auto focus on.)
.
DIGITAL ZOOM
Please note that the EYE-10 has an optical 12x zoom. The digital 2x zoom increases the overall zoom
range to a 24x zoom. When zooming in, the zoom stops at the biggest enlargement in the optical zoom.
When the ZOOM IN key is pressed again, 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 is that a message appears on-screen when you are in the digital zoom mode.
The behaviour of the EYE-10 in the digital zoom mode can be changed in the on-screen menu.
AUTO IRIS / MANUAL IRIS
The EYE-10 is equipped with an auto iris function. This means that the brightness of the camera image
adjusts automatically. When using the IRIS keys (#16) the auto iris function is switched off. In this mode the
iris can be manually adjusted. When using the ZOOM keys (#14) the auto iris is switched on again.
The iris also controls the AGC (Auto Gain Control) and ASC (Auto Shutter Control) functions (if these are
enabled).
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.)
WHITE BALANCE
Correct white balance adjustment is important for an exact color reproduction!
"Auto Tracking" is the default white balance setting when the EYE-10 is shipped. This means that the
white balance is continuously being automatically adjusted. For an exact white balance, 10% of the
recorded image should be white (with the measurement area being the center of the image).
For a precisely fixed white balance adjustment use the "One Push" white balance (OWB). This can be done
by completely zooming in on a white sheet of paper and pressing the WHITE key (#17). When the white
balance is stored, an on-screen message appears. Setting a "One Push" white balance switches off the
"Auto Tracking" mode (When the unit is switched off and on again the "Auto Tracking" mode will be
reactivated). When the lighting conditions change (e.g. sunlight or different room light) the white balance
should be readjusted!
For specialists: The EYE-10 can be switched between "Auto Tracking", "One Push" and "Manual" white
balance mode in the on-screen menu.
SHUTTER CONTROL (ASC)
The shutter virtually extends the iris-range if the iris is fully closed mechanically.
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 in 50Hz and 60Hz-countries.
The behaviour of the ASC can be changed in the on-screen menu and with the RS-232 camera control
software.
AUTO GAIN CONTROL (AGC)
The gain virtually extends the iris-range if the iris is fully opened mechanically.
The behaviour of the ASC can be changed with the RS-232 camera control software (For more details, see
camera control software manual on the WolfVision homepage www.wolfvision.com/support).
The maximum value for AGC can be changed in the on-screen Extra menu.
FREEZE
The current image can be captured by pressing the FREEZE key (#23).
