About Image Acquisition Object Properties
The video input object and the video source object both support properties that enable
you to control characteristics of the video image and how it is acquired.
The video input object properties control aspects of an acquisition that are common to all
image acquisition devices. For example, you can use the FramesPerTrigger property to
specify the amount of data you want to acquire.
The video source object properties control aspects of the acquisition associated with a
particular source. The set of properties supported by a video source object varies with
each device. For example, some image acquisition devices support properties that enable
you to control the quality of the image being produced, such as Brightness, Hue, and
Saturation.
With either type of object, you can use the same toolbox functions to
• View a list of all the properties supported by the object, with their current values
• View the value of a particular property
• Get information about a property
• Set the value of a property
Note Three video input object trigger properties require the use of a special configuration
function. For more information, see “Setting Trigger Properties” on page 5-21.
