reduce the lens aperture, the intensity of your illumination, the camera's exposure time setting, or the
camera's gain setting.
3)
Possible image distortion
Objects will only appear undistorted in the image if the numbers of binned rows and columns are equal.
With all other combinations, objects will appear distorted. For example, if you combine vertical Binning by
2 with horizontal Binning by 4, the target objects will appear squashed.
4)
Mutually exclusive with Decimation
Binning and Decimation cannot be used simultaneously in the same direction. When the horizontal Binning
value is set to a value other than 1, the horizontal Decimation feature cannot be used. When the vertical
Binning value is set to a value other than 1, the vertical Decimation feature cannot be used.

Decimation
The Decimation can reduce the number of sensor pixel columns or rows that are transmitted by the camera,
reducing the amount of data that needs to be transmitted and reducing bandwidth usage.
How Vertical Decimation Works
On mono cameras, if you specify a vertical Decimation factor of n, the camera transmits only every n
th
row.
For example, when you specify a vertical Decimation factor of 2, the camera skips row 1, transmits row 2,
skips row 3, and so on.
On color cameras, if you specify a vertical Decimation factor of n, the camera transmits only every n
th
pair
of rows. For example, when you specify a vertical Decimation factor of 2, the camera skips rows 1 and 2,
transmits rows 3 and 4, skips rows 5 and 6, and so on.

As a result, the image height is reduced. For example, enabling vertical Decimation by 2 halves the image
height. The camera automatically adjusts the image ROI settings.
Vertical Decimation significantly increases the camera's frame rate. For details, please refer to the section
