Considerations When Using Decimation

Reduced Resolution
Using vertical decimation effectively reduces the vertical resolution of the camera's imaging sensor.
Likewise, horizontal decimation, effectively reduces the horizontal resolution of the camera's
imaging sensor.
Image Distortion
When only vertical decimation is used, the imaged objects appear shrunk in vertical direction. If, for
example, vertical decimation is set to 2, the imaged objects appear shrunk by a factor of 2 compared
to the horizontal direction and compared to an image without decimation. Likewise, horizontal
decimation shrinks a frame in horizontal direction.
Binning and Vertical Decimation
If vertical binning is used, vertical decimation is automatically disabled, and vice versa, i.e. if vertical
decimation is used, vertical binning is disabled.
Horizontal binning works independently from the decimation feature.
