Document acknowledge system having horizontal/vertical-run length smoothing algorithm circuits and a document region divide circuit

摘要

A document acknowledge system comprising horizontal/vertical- run length smoothing algorithm circuits in which a horizontal-run length smoothing algorithm (H-RLSA) and a vertical-run length smoothing algorithm (V-RLSA) are performed by hardware and a document region divide circuit for dividing a document region in which the smoothed data is logical-produced by hardware. Therefore, the horizontal-run length smoothing algorithm circuit can smooth horizontal data not with software executed by a microprocessor, but with hardware, the horizontal data stored by scanning a document horizontally. Also, the vertical-run length smoothing algorithm circuit can smooth vertical data not with software executed by a microprocessor, but with hardware, the vertical data stored by scanning the document vertically. Moreover, the document region divide circuit can divide a document region in which the smoothed data is logical-produced by hardware.
