optical character recognition (OCR), method for the machine-reading of typeset, typed, and, in some cases, hand-printed letters, numbers, and symbols using optical sensing optical sensing, in general, any method by which information that occurs as variations in the intensity, or some other property, of light is translated into an electric signal. This is usually accomplished by the use of various photoelectric devices. ..... Click the link for more information. and a computer. The light reflected by a printed text, for example, is recorded as patterns of light and dark areas by an array of photoelectric cells photoelectric cell or photocell, device whose electrical characteristics (e.g., current, voltage, or resistance) vary when light is incident upon it. .....

A computer program analyzes the patterns and identifies the characters they represent, with some tolerance for less than perfect and uniform text. OCR is also used to produce text files from computer files that contain images of alphanumeric characters, such as those produced by fax transmissions.
