1. A character recognition apparatus for recognizing an entered pattern comprising: display means for displaying a plurality of patterns having a first and second pattern, wherein the plurality of patterns represent transformations of the first pattern transforming into the second pattern or vice versa; designation input means, arranged together with the display means, for selecting one of the displayed intermediate patterns between the first and second patterns, which is designated by a user, and assigning the first pattern to a selected intermediate pattern as a first group and the pattern immediately after the selected intermediate pattern to the second pattern as a second group; setting means for setting a feature quantity of the selected intermediate pattern as a threshold value for identifying said first and second patterns in a character recognition process; identifying means for identifying to which group the entered pattern belongs on the basis of said threshold value; and output means for outputting character code corresponding to the first or second pattern included in the group identified by said identifying means as a recognition result for the entered pattern.
