Abstract

An electronic dictionary apparatus which is capable of actively supporting the thinking of the user during its use, and which has the improved maneuverability and the wider utility. In the apparatus, each letter pattern series in the entered input document is automatically extracted and recognized in order to obtain a corresponding letter code series; then the entered input document superposed with an enclosure image enclosing each letter pattern series for each of the extracted and recognized letter pattern series is displayed; then a user specifies a desired one of the displayed letter pattern series enclosed by the enclosure image; and then information on the letter code series corresponding to the specified letter pattern series is looked up in the data-base containing prepared information on a number of letter patterns in terms of letter codes.
