Document Imaging is an information technology category for systems and software capable of capturing, storing and managing scanned documents (document images).

Document Imaging is part of the set of technologies that conform the Enterprise Content Management category.

In the early days of content management technologies, the term "Document Imaging" was used interchangeably with "Document Management" since this was the first technology available for managing documents.

In the late 80's and early 90's a new document management technology emerged: Electronic Document Management. This new technology was built around the need to manage and secure the high volume of electronic documents ( spreadsheets, word processing documents) created in organizations.

Unlike images which once captured ("scanned") remain unchanged, electronic documents are changed constantly and those changes require security authorizations and tracking, which are the core functionality of an EDMS (Electronic Document Management System)
