Abstract

System 10 allows an optical character recognition (OCR) machine to transmit specified fields of a document 11 to data processor 12 in a noncoded or facsimile form, as well as transmitting recognition codes for characters in other fields of the document. Both types of fields may be processed in a single pass of document 11 through the system. This type of system is useful for purposes such as the augmentation of hard-wired recognition units by software, and the storage of pictorial information for retrieval by a recognized alphanumeric tag associated with it on document 11.

Collection of Noncoded Data Field on an Optical Character Recognition Machine

System 10 allows an optical character recognition (OCR) machine to transmit specified fields of a document 11 to data processor 12 in a noncoded or facsimile form, as well as transmitting recognition codes for characters in other fields of the document. Both types of fields may be processed in a single pass of document 11 through the system. This type of system is useful for purposes such as the augmentation of hard-wired recognition units by software, and the storage of pictorial information for retrieval by a recognized alphanumeric tag associated with it on document 11.

Data processor 12 transmits command words to format control unit 13 for specifying the coordinates of document fields to be scanned, the orientation of the scans, a symbol set or font to be recognized, and other control parameters. Format control 13 then causes scan selector 14, scan generator 15 and recognition unit 16 to execute predetermined functions in accordance with the command words. Systems of this type are shown in U. S. patents 3,571,797 to Hardin et al and 3,618,018 to Johnston et al.

To achieve the direct collection of video images, video detector 17 also transmits video data to adapter 18. Adapter 18 translates these data into run- length codes, indicating the distance between adjacent transitions from white-to- black and vice versa. Other codes may be employed, or the video bits may be left in uncoded f...
