Improved Image Capture Technologies: WIA
Windows XP supports still-image devices through Windows Image Acquisition (WIA), which uses the Windows Driver Model (WDM) architecture. WIA 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.
WIA 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. WIA also supports Microsoft DirectShow®−based webcams and digital video (DV) camcorders to capture frames from video.
