Abstract

A hand-written character recognition apparatus can enhance recognition efficiency by decreasing erroneous recognition caused by habit of user's hand-writing stroke. In a hand-written character recognition apparatus in which user's strokes entered by some suitable means, such as light pen or tablet, are detected, then processed by a character recognition preprocessing, then processed by a recognizing processing for selecting nominated characters based on a standard evaluation point and further, processed by a post-recognizing processing and then supplied to an application device (electronic notebook, electronic dictionary, word processor, personal computer or the like). Characters causing erroneous recognition due to user's hand-writing stroke habit are subtracted from the standard evaluation point according to a demerit system by use of a nominated character dictionary in which evaluation points based on standard strokes for recognition processing are written and a minus-dictionary in which user's hand-writing stroke habits are written.
