Namespace:  ASCOM.DeviceInterface
Assembly:  ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 3c9121baba46811fe6e53a58a05935662261416d

Property Value

Type: ArrayList
The list of supported integration rates in seconds.
NotConnectedExceptionMust throw exception if data unavailable.
PropertyNotImplementedExceptionMust throw exception if camera supports only one integration rate (exposure) that cannot be changed.
Digital and integrating analogue video cameras allow the effective exposure of a frame to be changed. If the camera supports setting the exposure directly i.e. 2.153 sec then the driver must only return a range of useful supported exposures. For many video cameras the supported exposures (integration rates) increase by a factor of 2 from a base exposure e.g. 1, 2, 4, 8, 16 sec or 0.04, 0.08, 0.16, 0.32, 0.64, 1.28, 2.56, 5.12, 10.24 sec. If the camers supports only one exposure that cannot be changed (such as all non integrating PAL or NTSC video cameras) then this property must throw PropertyNotImplementedException.
