Abstract
A character pattern recognition method and apparatus for recognizing an unknown character pattern in accordance with a correlation between the unknown character pattern and each known standard character pattern, in which the unknown character pattern is temporarily stored in a magnetic thin plate in a form of a magnetic domain pattern. The magnetic domain pattern is modified by varying the bias magnetic field on the magnetic thin plate to provide a modified unknown character pattern emphasizing the feature of the unknown character pattern stored in the magnetic thin plate. The modified unknown character pattern is compared with each known modified feature enhanced standard character pattern to obtain the correlation.
