Binning - Basler A102K User Manual

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 CCT+ (see Section 4.1 and the
configuration tool's on-line help file) or binary commands (see Section 4.2). With the CCT+, you
use the Horizontal Binning and Vertical Binning settings on the AOI & Binning tree 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).
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.
Reduce the lens aperture, light intensity, or exposure in this case.
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 3-26.
3.9.2 Horizontal Binning
With horizontal binning, the digitized data of pairs of
adjacent pixels in each line are averaged and reported
out as a single pixel (see Figure 3-17). Horizontal
binning does not change the camera's responsivity to
light but it reduces the noise portion in the pixel output.
Horizontal binning improves the signal-to-noise ratio in
the camera output by typically 3 dB.
When horizontal binning is active, image resolution
decreases to 696 pixels (H) by 1040 pixels (V).
