Image recognition device, copy apparatus and image recognition method
First Claim
1. An image recognition device comprising:
- a processor;
a memory storing computer executable instructions that, when executed, cause the image recognition device to function as;
a first determination unit configured to determine whether a surrounding image is included in image information read from a document, wherein the surrounding image is part of a specific image in which the surrounding image surrounds a surrounded image; and
a second determination unit configured to determine whether the specific image is included in the image information,wherein the second determination unit is configured to divide an extraction region positioned at a center of the surrounding image into N×
N regions, wherein N is an odd-number of three or more, and to extract N×
N images to be processed,wherein the second determination unit determines whether the specific image is included in the image information by checking N×
N images to be processed with a specific image template once the first determination unit has determined the surrounding image is included in the image information;
a first image processing means provided downstream of a reading means, including, in order from upstream to downstream, an A/D converter, a D-range correction unit, a reading gamma correction unit, a variable magnification processing unit, a filtering unit, a masking unit, a GCR unit, a recording gamma correction unit, a binarization unit, and a recording unit; and
a second image processing means provided downstream of the position of the D-range correction unit of the first image processing means and parallel to a position from the reading gamma correction unit to the recording unit in the first image processing means, the second image processing means including, in order from upstream to downstream, a gamma correction unit, a variable magnification processing unit, a filtering unit, and a binarization unit,wherein the binarization unit of the second image processing means is configured to perform binarization according to a luminance of input RGB values, wherein conversion to luminance is performed by weighting, including attaching importance to, a color which is used for a specific mark corresponding to the specific image.

Abstract
An image recognition device of the invention includes an image reading means for reading image information from a manuscript, discriminating a specific image in which a surrounded image is surrounded by a surrounding image from the image information. The image recognition device includes a first determination means for determining whether the surrounding image is included in the image information or not and a second determination means for determining whether there is the specific image in the image information or not by extracting n×n images to be processed by dividing an extraction region positioned at the center of the surrounding image into n×n regions (“n” is an odd-number of three or more) when the first determination means determines that the surrounding image is included in the image information, then, by checking respective images to be processed with a specific image template.
