WIA and STI Driver Reference Table

The following table contains reference information for Windows Image Acquisition (WIA) drivers and for Still Imaging (STI) drivers. These drivers control devices, including scanners and cameras, that capture still images. For more information about these drivers, see Windows Image Acquisition Drivers and Still Image Drivers.

The following sections describe the interfaces, functions, structures, and properties used by WIA and STI drivers.
