Determining Supported Video Formats
The video format specifies the characteristics of the images in the video stream, such as
the image resolution (width and height), the industry standard used, and the size of the
data type used to store pixel information.
Image acquisition devices typically support multiple video formats. You can specify the
video format when you create the video input object to represent the connection to the
device. See “Creating Image Acquisition Objects” on page 5-8 for more information.
Note Specifying the video format is optional; the toolbox uses one of the supported
formats as the default.
