8.7.2 Binning on Color Cameras (acA1920-25uc and
acA2500-14uc Only)
The acA1920-25uc and acA2500-14uc color cameras allow 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 93).
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.
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 94).
