Remarks

Must be implemented, must not throw a PropertyNotImplementedException.

This can be used, for example, to specify the resolution of a user interface "spin control" used to dial in the exposure time.

Please note that the Duration provided to StartExposure does not have to be an exact multiple of this number; the driver should choose the closest available value. Also in some cases the resolution may not be constant over the full range of exposure times; in this case the smallest increment would be appropriate. A value of 0.0 shall indicate that there is no minimum resolution except that imposed by the resolution of the double value itself.

It is recommended that this function be called only after a connection is established with the camera hardware, to ensure that the driver is aware of the capabilities of the specific camera model.

This is only available for the Camera Interface Version 2 and later.
