Implements
IVideoV2SupportedIntegrationRatesExceptions| Exception | Condition |
|---|---|
| PropertyNotImplementedException | Must throw exception if camera supports only one integration rate (exposure) that cannot be changed. |
| NotConnectedException | If the device is not connected |
| DriverException | An error occurred that is not described by one of the more specific ASCOM exceptions. Include sufficient detail in the message text to enable the issue to be accurately diagnosed by someone other than yourself. |
Remarks
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 camera supports only one exposure that cannot be changed (such as all non integrating PAL or NTSC video cameras) then this property must throw PropertyNotImplementedException.
