Claims

An image processing apparatus having an area separating means for separating a photograph area, a graphic area, and a character area from image data to be processed,
The region separating means includes
Character area first extracting means for extracting a character area from the image data prior to a photograph area and a graphic area, and a photo area and a graphic area are extracted from the data remaining after the character area is extracted from the image data. An image processing apparatus characterized by separating.

The region separating means includes
The image processing apparatus according to claim 1, further comprising a photographic area preceding extraction unit that extracts a photographic area before a graphic area from data remaining after extracting a character area from the image data. .

The region separating means includes
The image processing apparatus according to claim 1, further comprising a graphic area preceding extraction unit that extracts a graphic area from a remaining data after extracting a character area from the image data. .

The photograph area preceding extraction means is
First region segmentation processing is performed on the data remaining after the character region is extracted from the image data, and a first region segmentation process that can be segmented into a plurality of predetermined regions is performed, and a photograph region is extracted from the segmented regions. Means,
The data obtained by further extracting the photographic area by the first photographic area extracting means from the data remaining after the character area is extracted from the image data can be divided into a plurality of areas smaller than the predetermined area. The image processing apparatus according to claim 2, further comprising: a second photographic area extracting unit that performs a two-area dividing process and extracts a photographic area from the divided areas.

The graphic area preceding extraction means
A first graphic area extraction is performed by performing a first area dividing process on the data remaining after the character area is extracted from the image data, and extracting a graphic area from the divided areas. Means,
The data obtained by further extracting the graphic area by the first graphic area extracting means from the data remaining after the character area is extracted from the image data can be divided into a plurality of areas smaller than the predetermined area. The image processing apparatus according to claim 3, further comprising: a second graphic area extracting unit that performs a two-area dividing process and extracts a graphic area from the divided areas.

The first area dividing process detects edges of a binary image in which a character area is extracted from the image data and a portion of a photographic area or a graphic area in the remaining data is distinguished from a background portion other than these. It is possible to divide into a plurality of predetermined areas, and the second area dividing process detects the edges of the remaining data by further extracting the photographic area from the remaining data after extracting the character area from the image data, The image processing apparatus according to claim 4, wherein the image processing apparatus can be divided into a plurality of areas smaller than the predetermined area.

The first area dividing process detects edges of a binary image in which a character area is extracted from the image data and a portion of a photographic area or a graphic area in the remaining data is distinguished from a background portion other than these. It is possible to divide into a plurality of predetermined areas, and the second area dividing process detects the edges of the data remaining after the graphic area is further extracted from the data remaining after the character area is extracted from the image data, The image processing apparatus according to claim 5, wherein the image processing apparatus can be divided into a plurality of areas smaller than the predetermined area.

The image according to any one of claims 1 to 7, further comprising reading means for obtaining image data by reading an original, wherein the image data to be processed is obtained by the reading means. Processing equipment.

An image processing method having a region separation step of separating a photo region, a graphic region, and a character region from image data to be processed,
The region separation step includes:
A character region is extracted from the image data prior to a photographic region and a graphic region, and the photographic region and the graphic region are separated from data remaining after the character region is extracted from the image data. An image processing method.

An image processing program having an area separation procedure for separating a photo area, a graphic area, and a character area from image data to be processed,
The region separation procedure includes:
A character area is extracted from the image data prior to a photographic area and a graphic area, and the photographic area and the graphic area are separated from data remaining after the character area is extracted from the image data. An image processing program.

A computer-readable recording medium on which the image processing program according to claim 10 is recorded.
