Control Parameters

The basic MultiCam parameter to control the exposure duration is Expose_us. The exposure time is expressed in microseconds (10-6 s).

As an example, to program the exposure time to a value of 600 μs, simply set Expose_us to 600.

A second parameter called ExposeTrim is available. This parameter provides a way to trim, or modify, the exposure duration as originally set by the Expose_us parameter.

The trimming parameter works in the following range:

It has been chosen to provide the trimming control on a logarithmic scale. Consequently, the ExposeTrim unit is the decibel with a range -12 dB to +6 dB.
