Text/Image Separation by Fax with OCR

      Disclosed is a method to reduce amount of data to be
transmitted but still keeping a layout information using OCR
capability of facsimile device or program.

      When transmitting a document containing mixture of characters,
drawings and image/pictures, the amount of data is significantly
large.  If the data on the document is separated to coded information
and non-coded information, using recognition technology such as OCR,
data amount can be reduced when replacing portion recognized as coded
information by space.  Recognized coded information would be
represented by, for example ASCII or any character set which both
sender and receiver can recognize.  Data transmitted consists of
coded information, non-coded information which is not recognized as
coded information and processed as usual FAX data, and document
layout information, in order to reconstruct document at the receiving
side.

      By separating document into coded information and non-coded
information, document can be more easily processed by the receiving
side.  Also by performing recognition process at sending side, the
recognition process can be optimized to the scanning capability.

      Traditional Technique - The current FAX technology is more or
less optimized to the typed characters with certain type face and
pitch, and the document with mix objects, such as characters,
drawings, and images, causes transmission inefficiency, in terms of
