Camera Attributes
Cameraattributes allow you to control camera-specific features such as
brightness and shutter speed directly from NI-IMAQ for 1394. You can
also setcamera attributes through the feature tab in MAX. A llof the
configuredparameters for a camera are stored in a camera (.icd) file. This
file islinked to a specific camera.
The followingattributes are defined in the IEEE-1394 Based Digital
CameraSpecifications—Brightness, Auto_Exposure, Sharpness,
White_Balance,Hue, Saturation, Gamma, Shutter,Gain, Iris, Focus,
Temperature,Zoom, Pan, Tilt, and Optical Filter.
Tomodify these attributes in LabVIEW,use the IMAQ1394 Attribute VI.
Set the Get/Set parameterto FALSE to read the current value of the
attribute,and TRUE to write the new value of the attribute.
