Difference Between Optical Scanner and Optical Reader

Optical Scanner vs Optical Reader

Summary: Difference Between Optical Scanner and Optical Reader is that an optical scanner, usually called a scanner, is a light-sensing input device that reads printed text and graphics and then translates the results into a form the computer can process. While an optical reader is a device that uses a light source to read characters, marks, and codes and then converts them into digital data that a computer can process.

Difference Between Optical Scanner and Optical Reader

Optical Scanner

An optical scanner, usually called a scanner, is a light-sensing input device that reads printed text and graphics and then translates the results into a form the computer can process. A flatbed scanner works in a manner similar to a copy machine except it creates a file of the document in memory instead of a paper copy. Once you scan a picture or document, you can display the scanned object on the screen, modify its appearance, store it on a storage medium, print it, fax it, attach it to an e-mail message, include it in another document, or post it on a Web site or photo community for everyone to see.

Many scanners include OCR (optical character recognition) software, which can read and convert text documents into electronic files. OCR software converts a scanned image into a text file that can be edited, for example, with a word processing program.

Optical Reader

An optical reader is a device that uses a light source to read characters, marks, and codes and then converts them into digital data that a computer can process. Two technologies used by optical readers are optical character recognition and optical mark recognition.

Optical character recognition (OCR) involves reading typewritten, computer-printed, or handprinted characters from ordinary documents and translating the images into a form the computer can process. Most OCR devices include a small optical scanner for reading characters and sophisticated software to analyze what is read.

(OMR) devices read hand-drawn marks such as small circles or rectangles. A person places these marks on a form, such as a test, survey, or questionnaire answer sheet.

OMR and OCR both uses as optical readers. But you can read out the difference between Optical Character Recognition and Optical mark recognition.
