image preview and device configuration -凯发k8网页登录

preview image and adjust acquisition parameters such as brightness, resolution, and region of interest (roi)

it is common to do two things before starting an acquisition — set properties and preview the image. the preview function opens a live preview window after you create a videoinput or other type of acquisition object.

you can set object-specific properties or device-specific properties to control the acquisition. for more information, see .

note: the functionality for all supported hardware is now available via the support package installer. starting with r2014a, each adaptor is available separately through the support package installer, and you must install the appropriate support packages to use the toolbox with your hardware. for more information, see .
