This enumeration provides values that identify types of camera settings.
Syntax
typedef enum { CameraControl_Pan, CameraControl_Tilt, CameraControl_Roll, CameraControl_Zoom, CameraControl_Exposure, CameraControl_Iris, CameraControl_Focus CameraControl_Flash } CameraControlProperty; |
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

- 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.
- CameraControl_Flash
-
Specifies if the flash is turned on or off.
Remarks
For a given property, a particular device might implement only a subset of the listed range.
