Abstract

The invention provides a document editing apparatus by which a hand-written inputted editing operation can be reflected on a document without deterioration of the efficiency in editing operation. Editing operations recognized by an editing operation recognition section based on locus data, that is, information hand-written inputted using a locus data inputting section, are stored once into an editing operation storage section. Each time an editing operation is inputted, an editing operation which satisfies a determination condition stored in a determination condition storage section is searched from among the editing operations stored in the editing operation storage section by a determination section. Then, only the editing operation thus searched out is reflected on the document by a document editing section.

Claims

1. A document editing apparatus, comprising:

a pointing device;

display means for displaying a document to be edited and image data representative of locus data inputted by said pointing device;

editing operation storage means for temporarily storing editing operations to be executed for the document displayed on said display means;

editing operation recognition means for recognizing, based on the locus data inputted by said pointing device, the editing operations to be executed for the document;

determination means for determining, when the editing operations are recognized by said editing operation recognition means, whether or not the editing operations stored in said editing operation storage means include an editing operation which satisfies a predetermined condition;

editing operation execution means for executing, when said determination means determines that the editing operations include an editing operation which satisfies the predetermined condition, editing corresponding to the editing operation for the document and erasing the editing operation used for the editing from said editing operation storage means; and

editing operation loading means for loading the editing operations recognized by said editing operation recognition means into said editing operation storage means.

2. A document editing apparatus as claimed in claim 1, wherein the condition to be used for the determination by said determination means is that a portion of the document for which one of the editing operations recognized by said editing operation recognition means is to be performed does not move in said document display means.

3. A document editing apparatus as claimed in claim 1, wherein said determination means selects the condition to be used for the determination from within a plurality of conditions registered in advance therein.

4. A document editing apparatus as claimed in claim 1, wherein said pointing device is in the form of a pen.

5. A document editing apparatus, comprising:

a pointing device;

display means for displaying a document to be edited and image data representative of locus data inputted by said pointing device;

editing operation storage means for temporarily storing editing operations to be executed for the document displayed on said display means;

editing operation recognition means for recognizing, based on the locus data inputted by said pointing device, the editing operations to be executed for the document;

discrimination means for discriminating whether or not the number of characters of the document changes if one of the editing operations recognized by said editing operation recognition means is executed;

first editing operation execution means for executing, when said discrimination means discriminates that the number of characters of the document does not change, editing corresponding to the editing operation for the document;

determination means for determining, when the editing operations are recognized by said editing operation recognition means, whether or not the editing operations stored in said editing operation storage means include an editing operation which satisfies a predetermined condition;

second editing operation execution means for executing, when said determination means determines that the editing operations include an editing operation which satisfies the predetermined condition, editing corresponding to the editing operation for the document and erasing the editing operation used for the editing from said editing operation storage means; and

editing operation loading means for loading any of the editing operations determined to cause a change in number of characters by said discrimination means into said editing operation storage means.
