ICameraV2ExposureResolution Property

Exposure resolution

Namespace:  ASCOM.DeviceInterface
Assembly:  ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 3c9121baba46811fe6e53a58a05935662261416d
double ExposureResolution { get; }

Return Value

Type: Double
The smallest increment in exposure time supported by StartExposure.
NotConnectedExceptionMust throw an exception if the information is not available. (Some drivers may require an active connection in order to retrieve necessary information from the camera.)
InvalidValueExceptionMust throw an exception if not valid.

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 resulution 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
