The Microsoft Windows Image Acquisition (WIA) interface is both an application programming interface (API) and a device-driver interface (DDI). The WIA API is designed to allow applications to run in a process that is separate from the driver, enumerate available image acquisition devices, create simultaneous connections to multiple devices, query properties of devices in a standard and expandable manner, acquire device data by using standard and high-performance transfer mechanisms and be notified of a wide variety of device events.
