Image
The image panel displays information about the picture geometry, the pixel clock and
it allows for the following settings:
•
AOI (area of interest) which can be less or equal the imager size
•
Binning mode (off, vertical, horizontal, 2x2)
No Binning
= full resolution: horizontal x 1, vertical x 1 (default setting)
H2 x V2 x: vertical 2 x and horizontal 2 x at the same time; Resolution: horizontal x
½, vertical x ½, Sensitivity is 4 x, pixel frequency is halved, max. frame rate is almost
doubled. “No Binning” sets the camera to full resolution, H1 x 2 and 2 x 1 binning is
also available
If you need other binning mode configurations consult factory or your nearest distrib-
utor.
Please note:
Using binning with a color version of the camera will cause incor-
rect colors and strange effects!
However, for fast focusing it might be useful.
•
Pixel depth (8-bit, 12-bit, 16-bit, if supported by camera)
•
Color (On/Off)
•
Bayer method (Disabled, Nearest neighbor, Simple, Bilinear, HQ Linear, Edge Sense,
Gray)
•
Factors for white balance (Red, Green, Blue)
•
“Balance” button for performing automatic white balance
•
“Equalize” button for setting all colors to 100%
•
Freeze (display switched off while acquisition continuous, for test purposes)
In addition the number of transferred frames is displayed as well as the number of
eventually lost frames. A frame loss may happen for example in case of an insufficient
network bandwidth or if the network connection gets interrupted for a short time or in
case of other network failures.
Further the number of resent network packets is displayed. The second number is the
last resent packet number and the first number indicates the total number of resent
packets.

Gain
The gain panel allows for adjusting gain and Autogain with the following controls:
The default gain setting is “0” dB. You may change the gain up to 6 dB (or higher) in steps of
1/10
th
. Note that the dark offset will increase and dynamic range will not be improved. Please note
that noise also is amplified. For good image quality do not increase gain more than 6 dB;
higher
Gain is possible but not specified!
4.6
Offset
Dark level offset adjustment is possible. When 8 Bit are transmitted it can be changed
from 0 to 255. Please note that factory adjustment is optimized for DR and sensitivity.
You may lose dynamic range. Alter only if you operate at high temperatures like +40
°C.
