Exceptions Exception | Condition |
---|
NotConnectedException | Must 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.) |
InvalidValueException | Must throw an exception if not valid. |
PropertyNotImplementedException | Must throw an exception if Gamma is not supported. |
Remarks Gamma can be used to adjust the gamma setting of the camera, if supported. There are two typical usage scenarios:
- Discrete gamma video cameras will return a 0-based array of strings - Gammas, which correspond to different discrete gamma settings supported by the camera. Gamma must be set to an integer in this range. GammaMin and GammaMax must thrown an exception if
this mode is used.
- Adjustable gain video cameras - GammaMin and GammaMax return integers, which specify the valid range for Gamma.
The driver must default Gamma to a valid value.
