CameraControlProperty Enumeration

Summary

The CameraControlProperty enumeration values define individual settings in a camera.

Syntax

C++/CLI

public enum CameraControlProperty

public enum class CameraControlProperty

Members

Value	Member	Description
0	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.
1	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.
2	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.
3	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.
4	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.
5	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.
6	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.
19	Auto_Exposure_Priority	Specifies the auto-exposure priority property. Auto-exposure priority determines whether the camera can dynamically vary the frame rate depending on lighting conditions. A value of 0 keeps the frame rate constant. A value of 1 allows the frame rate to dynamically vary. The camera must be in auto-exposure mode for the auto-exposure priority mode to be a valid option. The default value is 0.
