Property Description
DeviceFile Name of file specifying video format. This property
is only visible when VideoFormat is set to 'From
device file'.
DeviceProperties Object containing properties specific to the image
acquisition device.
ROI Region-of-interest for acquisition. This is set to the
default ROI value for the specified device, which is
the maximum resolution possible for the specified
format. You can change the value to change the size of
the captured image. The format is 1-based, that is, it
is specified in pixels in a 1-by-4 element vector [x y
width height].
Note that this differs from the videoinput object, the
Image Acquisition Tool, and the From Video Device
block, all of which are 0-based.
HardwareTriggering Turn hardware triggering on/off. Set this property to
'on' to enable hardware triggering to acquire images.
The property is visible only when the device supports
hardware triggering.
TriggerConfiguration Specifies the trigger source and trigger condition before
acquisition. The triggering condition must be met via
the trigger source before a frame is acquired. This
property is visible only when HardwareTriggering is
set to 'on'.
ReturnedColorSpace Specify the color space of the returned image. The
default value of the property depends on the device
and the video format selected. Possible values are
{rgb|grayscale|YCbCr} when the default returned
color space for the device is not grayscale. Possible
values are {rgb|grayscale|YCbCr|bayer} when
the default returned color space for the device is
grayscale
