Binning on Color Cameras (acA1920-25uc Only)
The acA1920-25uc color camera allows you to realize color binning, where pixel values for identical
colors are binned vertically and/or horizontally.
With vertical color binning, the gray values of adjacent pixels of the same color from 2 rows, 3 rows,
or a maximum of 4 rows in the imaging sensor array are averaged and are reported out of the
camera as a single pixel. The number of binned pixels depends on the vertical color binning setting
(see the example in Figure 80).
As the gray values are averaged during vertical color binning and not summed, the signal to noise
ratio will be increased while the camera's response to light will not be increased.
Example:
Vertical Color Binning by 2

With horizontal color binning, the gray values of adjacent pixels of the same color from 2 columns,
3 columns, or a maximum of 4 columns in the imaging sensor array are summed and are reported
out of the camera as a single pixel. The number of binned pixels depends on the horizontal color
binning setting (see example in Figure 81).
