Elements
CameraControl_Pan
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.CameraControl_Tilt
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.CameraControl_Roll
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.CameraControl_Zoom
Identifies the camera's zoom setting, in millimeters. Values range from 10 to 600, and the default is specific to the device.CameraControl_Exposure
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:Value Seconds -3 1/8 -2 1/4 -1 1/2 0 1 1 2 2 4 CameraControl_Iris
Specifies the camera's iris setting, in units of fstop * 10.CameraControl_Focus
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.
Remarks
For a given property, a particular device might implement only a subset of the listed range.
