The setting is controlled automatically.
The setting is controlled manually.
Identifies the exposure setting, in log base 2 seconds. In other words, for values less than zero, the exposure time is 1/2n seconds, and for values zero or above, the exposure time is 2n seconds. For example:
Specifies the camera's focus setting, as the distance to the optimally focused target, in millimeters. The range and default value are specific to the device.
Specifies the camera's iris setting, in units of fstop * 10.
Identifies the camera's pan setting, in degrees. Values range from –180 to +180, with the default set to zero. Positive values are clockwise from the origin (the camera rotates clockwise when viewed from above), and negative values are counterclockwise from the origin.
Identifies the camera's roll setting, in degrees. Values range from –180 to +180, with the default set to zero. Positive values cause a clockwise rotation of the camera along the image-viewing axis, and negative values cause a counterclockwise rotation of the camera.
Identifies the camera's tilt setting, in degrees. Values range from –180 to +180, with the default set to zero. Positive values point the imaging plane up, and negative values point the imaging plane down.
Identifies the camera's zoom setting, in millimeters. Values range from 10 to 600, and the default is specific to the device.
This class has no sub classes.
