Description: The Windows Image Acquisition (WIA) service provides image acquisition services for scanners and cameras.

Windows supports still-image devices through the WIA service, which uses the Windows Driver Model (WDM) architecture. The WIA service provides robust communication between applications and image-capture devices, allowing you to capture images efficiently and transfer them to your computer for editing and use. The service is needed to capture events generated by imaging devices.

The WIA service supports small computer system interface (SCSI), IEEE 1394, USB, and serial digital still-image devices. Support for infrared, parallel, and serial still-image devices — which are connected to standard COM ports — comes from the existing infrared, parallel, and serial interfaces. Image scanners and digital cameras are examples of still-image devices. The WIA service also supports Microsoft® DirectShow®−based Webcams and digital video (DV) camcorders to capture frames from video.

If this service is stopped or disabled, events from imaging devices are not captured and processed. If a WIA device is installed on the computer, the service will restart automatically when you restart the computer. Also, the service restarts any time a WIA-enabled application is started.
