Abstract
An optical character reader is provided with an input section which includes an image memory for storing image data received through a scanner which scans a document, a reduced image memory for storing reduced image data created by thinning the received image data, an enlarged image memory for storing enlarged image data for displaying an image which is enlarged with reference to a position indicated by a cursor on a display device, and a keyboard or the like through which various input data can be entered and a target area can be specified. With this character reader, the entire layout of the inputted image data can be displayed by using the reduced image data and a selected portion of the display can be enlarged to be visually inspected or recognized by the character reader.
