ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to document processors such as word processors or personal computers, and more particularly to a document image processor which reads image data of an original document and automatically sets a format for the document.
2. Description of the Background Art
Conventionally, when document data is printed out from a document processor such as a word processor, format information such as, for example, the (vertical/lateral) direction of a sheet of printing paper, a (vertical/lateral) printing direction, and a character size is set in correspondence to the document data.
Conventionally, a document recognizer has been known which scans a printed document to read the image of the document, and which recognizes and encodes the document image.
A method of utilizing the character recognizer has been considered whereby document data encoded by the recognizer is fed to a document processor such as a word processor. In this case, when the document data has been taken in from the recognizer, that format information is required to be newly set in correspondence to the document data.
However, it is very difficult to accurately set various format information so as to harmonize with the document image. That is, an error is likely to occur in the setting of the document information. Thus, this method has a disadvantage in that a document which reproduces the document image as it is can not be printed out.
SUMMARY OF THE INVENTION
According to the present invention, there is provided a document image processor comprising:
read means for reading a document image from a document;
character recognition means for recognizing and encoding a character from the document image read by the read means to thereby provide encoded document data;
document storage means for storing the encoded document data;
analysis means for analyzing the structure of the document when the character recognition means encodes the character;
production means for producing format information on the basis of the result of analysis of the structure of the document by the analysis means; and
setting means for setting the document information produced by the production means in correspondence to the encoded document data stored in the document storage means.
Thus, according to the present invention, the document image is read from the document and encoded. A format for a document accurately conforming to the document image is set in correspondence to the encoded document data, so that no special operations for setting the document format are required to thereby reduce a load on the user. Thus, a printed document reproduces the original document as it is.
