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.
How Horizontal Decimation Works
On mono cameras, if you specify a horizontal Decimation factor of n, the camera transmits only every n
th
column. For example, if specify set a horizontal Decimation factor of 2, the camera skips column 1,
transmits column 2, skips column 3, and so on.
