Patent Images
1. A document modification apparatus for modifying image data read by image input means, comprising:
- region extracting means for extracting a plurality of regions from the image data, each region being a unit to be modified;
region selection means for selecting target regions to be modified from the plurality of regions through an operator;
modification specifying means for specifying kinds of the modifications for the target regions selected by the region selection means through the operator; and
modification image making means for making a modified image, based on the kinds of the modifications, in the regions in the image data selected by the region selection means, specified by the modification specifying means;
wherein the region extracting means extracts rectangle regions as the target regions to be modified, and the region extracting means comprises a first judgment means for judging whether an attribute of the rectangle region is one of a “
character” and
“
ruled-line,” and
“
others,”
projection means for taking a projection data in vertical and horizontal directions of the rectangle region of the image data, and a second judgment means for judging whether the attribute of the rectangle region, whose attribute has been judged by the first judgment means as “
others,”
is one of a “
table,”
a “
photograph,” and
a “
frame”
according to a number of peaks detected from the projection data,operation of the second judgment means being based on whether the first judgment means identifies the attribute as “
others.”

Abstract
Automatic region extracting means (2) extracts rectangle regions having attributes of “character”, “photograph”, “table”, “ruled line”, “frame” from input image data through Image input means (1) and stores the information of the extracted rectangle regions into Modification information storage means (3). Display means (4) displays the input image including the extracted rectangle regions according to the information of the extracted rectangle regions. The operator selects desired extracted rectangle regions in the input image on a display screen and specifies the kind of the modification for the selected rectangle regions by using Operation means (5). Thereby, the information of both the selected rectangle regions and specified modifications are stored in Modification information storage means (3). Modification image making means (6) then makes the image data modified based on the information of the selected rectangle regions, the specified modification information, and the input image data, and Image output means (7) outputs the modified image.

7. A document modification apparatus for modifying image data read by image input means, comprising:
-
region extracting means for extracting a plurality of regions from the image data, each region being a unit to be modified; automatic modification means for automatically selecting target regions to be modified from the plurality of regions, and for automatically modifying the selected target regions based on modifications that have been set in advance; and modification image making means for making an image modified image in the target regions selected by the automatic modification means based on the kinds of the modifications determined by the automatic modification means; wherein the region extracting means extracts rectangle regions as the target regions to be modified, and the region extracting means comprise a first judgment means for judging whether an attribute of the rectangle region is one of a “
character” and
“
ruled-line,” and
“
others,”
