Abstract:
1. An image-processing apparatus having an image region distinction processing capability, comprising: an image data generation unit configured to generate image data from information read from an original document; a first region distinction unit configured to generate a character determination signal and edge feature amount image data by a region distinction between a character and a non-character using a previously set threshold value on the image data; a second region distinction unit configured to make the region distinction between the character and the non-character on the edge feature amount image data from the first region distinction unit to divide it into plural sub-region images and to display them, to adjust discrimination strength of each of the sub-region images, and to obtain a correction parameter according to the adjustment; an image processing control unit configured to cause the correction parameter to be reflected in the image region distinction of the first region distinction unit and to cause the region distinction processing to be performed again; and an image correction processing unit configured to image correct the image data based on the edge feature amount image data subjected again to the region distinction processing.
