  • Document revising system for use with document reading and translating system
    Patent number: 5222160
    Abstract: An image-to-character-position-correspondence-table producing unit produces image-to-character-position-correspondence-table composed of a set comprising an-image-of-a-document, a character-recognized document and a translated document. A candidate character producing unit produces candidate characters for revising misrecognized characters. A Japanese-document-to-translated-document correspondence table stores a correspondence relationship between an original Japanese document and a translated document in the form of a table. When misrecognized characters are being revised, the image-to-character-position-correspondence-table is displayed by the image-to-character-position-correspondence-table. A revising unit prompts a user to specify a misrecognized portion in the translated document of the image to character-position-correspondence-table.
