3.9 Binning
There are three types of binning available: vertical binning, horizontal binning, and full binning.
You can set binning using either the Camera Configuration Tool Plus (see Section 4.1 and the
configuration tool’s on-line help file) or binary commands (see Section 4.2 ). With the configuration
tool, you use the Horizontal Binning and Vertical Binning settings in the AOI & Binning group to
enable binning. To enable full binning, you must enable both Horizontal Binning and Vertical
Binning. With binary commands, you use the Horizontal Binning and Vertical Binning commands.
3.9.1 Vertical Binning
Vertical binning increases the camera’s responsivity to
light by summing the charges from adjacent pixels into one
pixel. With vertical binning, pairs of adjacent pixels from
two lines are summed and reported out as a single pixel.
Vertical binning reduces the noise portion in the pixel
output. With vertical binning, the signal-to-noise ratio will
increase by typically 1 to 2 dB.
When vertical binning is active, resolution decreases to
1392 (H) by 520 (V).

Binning should only be used on

monochrome cameras. Using binning on
A102
kc
color cameras is not recommended.

Using vertical or full binning generally increases the camera’s responsivity by up to
two times normal. After switching on binning, the image might look overexposed. Re-
duce the gain, lens aperture, light intensity, or exposure in this case.
For information on setting the gain when vertical binning is used, see Section
3.6.1.2 .
With vertical binning active, frame grabbers often require the information that the
vertical resolution is 520.
When vertical binning or full binning is used, the camera’s maximum allowed frame
rate increases. The maximum allowed frame rate can be calculated using the for-
mula given in Section
3.8.2.2 on page 3-28 .
