Members
| Member | Description |
|---|---|
| Exposure | Specifies the exposure (shutter speed) property. The exposure property is measured 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. |
| Focus | Specifies the focus property, as the distance to the optimally focused target. The focus property is measured in millimeters. The range and default value are specific to the device. |
| Iris | Specifies the iris property. The iris property is measured in units of (f-stop * 10). F-stop is a term used to indicate the amount of light passing through the lens. The smaller the f-number, the greater the amount of light passing through the lens. |
| Pan | Specifies the pan property. The pan property is measured in degrees. Possible values range from –180 to +180. The default value is zero. Positive values are clockwise from the origin (the camera rotates clockwise when viewed from above), and negative values are counterclockwise from the origin. |
| Roll | Specifies the roll property. The roll property is measured in degrees. Possible values range from –180 to +180. The default value is 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. |
| Tilt | Specifies the tilt property. The tilt property is measured in degrees. Possible values range from –180 to +180. The default value is zero. Positive values point the imaging plane up, and negative values point the imaging plane down. |
| Zoom | Specifies the zoom property. The zoom property is measured in millimeters. Values range from 10 to 600 or as stated by the device documentation. |
