摘要： A plurality of document definition information for identifying documents, and format control information for recognizing a character recorded on a document corresponding to each of the plurality of document definition information are held beforehand, documents targeted for character recognition are identified as specific documents based on document images of the entered documents targeted for character recognition and the document definition information and, based on a result of the identification, character recognition is executed by using corresponding format control information. A document definition device adds a plane area of each of documents to be identified to the document definition. An OCR device checks the plane area on the document by using the document definition before check of a preprint accompanied by character recognition.

摘要： A data input system is provided with an input pen. A sequence of characters are traced with the input pen, and image data on them are read from the image scanner incorporated in the input pen. Each character is recognized on the basis of the image data. If a recognition error occurs during the input processing, a correct character is written with the input pen. A locus of movement is traced on the basis of moving distance data, which is obtained by a moving distance sensor and includes a moving distance and a moving direction. A character represented by the traced locus is recognized.

摘要： An apparatus for detecting a character writing area inputs a plurality of images of written documents respectively having different characters recorded thereon to an existing document. The apparatus produces a common image and a differential image, based on the input images. By using of the common image and the differential image, a character-writing-areas are detected and an attribute is set for each of the areas. A format used for the written document is produced by using of the character-writing-areas and set attributes.

摘要： Predetermined spaces at different positions in a whole space possible to be given position information by dot patterns are allotted to a plurality of entry boxes provided in a sheet, and definition information for each sheet is associated in advance with the relation between the plural entry boxes and the spaces allotted thereto. At the time of the entry in the sheet, a pen device reads the dot pattern at the entry position and decodes the position information to output the position information to a host device. The host device determines a customer code corresponding to an arrangement of space numbers by using a series of the position information acquired from the pen device and a space number determination table.
