Abstract
An image processing device for processing an image read by an image scanner or similar image reading device is disclosed. The image processing device is capable of accurately detecting, without resorting to a range finding sensor or similar special sensing means, the bound portion of a spread book by recognizing the configuration of the bound portion out of a read image, and thereby accurately correcting the distortion of the portion of the image representative of the bound portion.
Claims51
An image processing device comprising:
- a glass platen configured to contact a spread book in an area of the spread book containing an image for processing by the image processing device;
- reading means for reading said image of the spread book;
- recognizing means for recognizing a configuration of the spread book based on the image read from the reading means;
- separating means for separating, based on data output from said reading means, a bound portion of the spread book between page portions;
- and
- correcting means for correcting, based on the configuration of the spread book recognized, a curvature distortion of an image representative of the bound portion of said spread book by performing an image shift in a main and sub-scanning direction.
