Scanning, OCR, imaging and drawing software is used in optical and document scanners, specialized imaging equipment, and optical character recognition (OCR) systems. Products are used to create, digitize, and modify images for storage on personal computers (PCs), compact discs, electronic document management (EDM) systems, and other storage media. Scanning software is designed to control and monitor flatbed, sheetfed, handheld, and drum scanners. OCR software converts scanned images into editable text that can be added to searchable databases, allowing the retrieval of scanned images based on their content. Imaging software allows users to resize, rate and label images; clone, paste, and paint visual elements; create mockups or other dimensional effects; and reduce noise. Drawing software is used to produce charts, diagrams, graphs, and illustrations. Other types of scanning, OCR, imaging and drawing software are also available.
