Abstract

PURPOSE:To easily recognize and correct the character of a same form which are difficult to be discriminated, through the use of attribute information by displaying recognition candidate characters and corresponding attribute information together. CONSTITUTION:A storage means 8 storing attribute information of the character for recognition is provided. When a recognition result differs from a correct word, or its is not discriminated to be the correct character or not due to the character of the same form, an operator uses an input means 6 and instructs a control means 7 of the display of the recognition candidate characters to a display means 5. The control means 7 reads attribute information 12 corresponding to the recognition candidate characters from the storage means 8 and transmits them to the display means 5 with the recognition candidate characters. Consequently, the operator uses displayed attribute information 12 and he can select and input the correct character from the recognition candidate characters 11.
