Document scanning creates digital files from physical documents. Document capture refers to bringing those scanned images, along with other digital files that may include photo and video files, into a document management system (DMS) or enterprise content management system (ECM). A document capture system automates processes, such as: extracting metadata used for indexing the files, or using optical character recognition (OCR) or key information extraction so that the captured material is searchable and more usable. Another common term, “Document Imaging System,” refers to the hardware and software used for document capture.
