Abstract
An apparatus for identifying a character which cannot be machine read so that the operator may observe and hopefully recognize the character in question. A bit-map video image of the unrecognized character(s) is inserted in the ASCII data line of neighboring characters to create an impression of the original line of text from the document. A data entry operator uses this information to enter the required correct character(s) via the keyboard or other means. This reject/reentry method allows for quick operator response, and minimizes data storage and transmission of video information.
