Claims

An image processing apparatus having an area separation unit that separates image areas having different attributes from image data to be processed,
The region separating means includes
A first area extracting means for performing a first area dividing process on the image data, which can be divided into a plurality of predetermined areas, and extracting an image area identified as a first attribute among the divided areas; A second area dividing process capable of dividing the data remaining after the image area identified as the first attribute is extracted from the image data by the first area extracting means into a plurality of areas smaller than the predetermined area; And second area extracting means for extracting the first attribute and the image area specified from among the divided areas.
An image processing apparatus.

The first area dividing process can be divided into a plurality of predetermined areas by detecting an edge of a binary image in which an image area portion in the image data and a background portion other than these are distinguished. The area dividing process is capable of dividing into a plurality of areas smaller than the predetermined area by detecting an edge of data remaining after the image area identified as the first attribute is extracted from the image data. The image processing apparatus according to claim 1.

The image processing apparatus according to claim 1, further comprising reading means for obtaining image data by reading a document, wherein the image data to be processed is obtained by the reading means.

An image processing method having a region separation step of separating image regions having different attributes from image data to be processed,
The region separation step includes:
A first region extracting step of performing a first region dividing process on the image data, which can be divided into a plurality of predetermined regions, and extracting an image region identified as a first attribute among the divided regions; A second region dividing process capable of dividing the data remaining after extracting the image region identified as the first attribute in the first region extracting step from the image data into a plurality of regions smaller than the predetermined region; And a second region extracting step of extracting the first attribute and the identified image region among the divided regions.
An image processing method.

An image processing program for causing an image processing apparatus to execute a region separation procedure for separating image regions having different attributes from image data to be processed,
The region separation procedure includes:
A first area extraction procedure for performing a first area dividing process on the image data, which can be divided into a plurality of predetermined areas, and extracting an image area identified as a first attribute among the divided areas; A second region dividing process capable of dividing data remaining after the image region identified as the first attribute in the first region extracting procedure from image data is divided into a plurality of regions smaller than the predetermined region; And a second region extraction procedure for extracting the first attribute and the specified image region among the divided regions.
An image processing program characterized by that.

A computer-readable recording medium on which the image processing program according to claim 5 is recorded.

  An image processing apparatus for separating a plurality of image areas from image data to be processed,
  For each of the image regions, region separating means for assigning at least one attribute among different attributes;
  Image processing means for performing image processing on each image area according to at least one attribute given by the area separating means;
  With
  The region separating means includes
  When the image area is an attribute to be prioritized among the different attributes for each of the image areas, the attribute to be prioritized is given to the entire image area,
  When only the small image area included in the image area is the attribute to be prioritized for each of the image areas, the attribute to be prioritized is given to the small image area.
  An image processing apparatus.

8. The image processing apparatus according to claim 7, further comprising reading means for obtaining image data by reading a document, wherein the image data to be processed is obtained by the reading means.

  An image processing method for separating a plurality of image regions from image data to be processed,
  For each of the image areas, an area separation step for assigning at least one attribute among different attributes;
  An image processing step of performing image processing on each image region according to at least one attribute imparted by the region separation step;
  With
  In the region separation step,
  When the image area is an attribute to be prioritized among the different attributes for each of the image areas, the attribute to be prioritized is given to the entire image area,
  When only the small image area included in the image area is the attribute to be prioritized for each of the image areas, the attribute to be prioritized is given to the small image area.
  An image processing method.

An image reading step of obtaining image data by reading a document;
The image processing method according to claim 9, wherein the image data to be processed is obtained by the original reading step.

  An image processing program for causing an image processing apparatus to separate a plurality of image regions from image data to be processed,
  An area separation procedure for assigning at least one attribute among different attributes for each of the image areas;
  An image processing procedure for performing image processing on each image region according to at least one attribute given by the region separation step;
  With
  In the region separation procedure,
  When the image area is an attribute to be prioritized among the different attributes for each of the image areas, the attribute to be prioritized is given to the entire image area,
  When only the small image area included in the image area is the attribute to be prioritized for each of the image areas, the attribute to be prioritized is given to the small image area.
