Abstract: An apparatus and a method for generating high-quality binary image are provided. An input unit inputs a binary image as a multi-valued image. A halftone dot image area map creating unit searches for a halftone dot image area that may be in the multi-valued image and creates a halftone dot image area map. A line drawing/character area map creating unit searches for a line drawing/character image area that may be in the multi-valued image and creates a line drawing/character image area map. A halftone dot image binarizing unit binarizes an input image corresponding to the halftone dot image area map while suppressing input read error that may occur when said input unit inputs the binary image, and generates a binarized halftone dot image. A line drawing/character smoothing unit smoothes a jaggy contained in an input image corresponding to the line drawing/character area map, and generates a binarized line drawing/character image.

Abstract: An image processing technique for generating a multi-valued image with fine contours from an input image that is generated by reading, as a multi-valued image, the dotted print contents of printed matter. An image processing apparatus of the present invention generates a contour extracted image by performing the contour extraction process for the input image, and deletes contours from the contour extracted image that satisfy a predetermined condition to generate a partial contour image. Then, the apparatus adds contours to the partial image according to the density distribution of the contour in the partial contour image, and generates a contour added image. By referring to the contour added image, the apparatus superimposes the input image and a smoothed image obtained by performing a smoothing process for the input image to generate a synthesized image.

Abstract: This invention provides a novel image correcting technique for automatically carrying out a suitable image correction. An image processing program of the invention includes a correction front-end unit for carrying out a color balance correction, a range correction, a main portion estimation processing, and a tone correction, a statistical information calculation unit for generating a color saturation reference value and a contour reference value as data expressing the preference of an operator by using an output of the correction front-end unit and a manually corrected image, and a correction back-end unit for carrying out a color saturation correction processing using the color saturation reference value stored in a reference value DB and a contour emphasis processing using the contour reference value. A processing result of the correction back-end unit is stored as an output image into an image storage DB.

Abstract: In an image processing apparatus according to the present invention, a brightest luminance value of the pixels of the processing image and a darkest luminance value of the pixels of the processing image are detected. An improper white balance and a luminance gradation of the processing image are corrected. Moreover, a luminance distribution of the processing image is leveled.

Abstract: In a moire fringes eliminating apparatus, a moire fringe eliminating unit comprises a halftone dot feature extracting unit, a re-calculation unit, a re-calculation deciding unit, and a halftone dot shape changing unit. The halftone dot feature extracting unit extracts features of the halftone dots. The re-calculation unit obtains a re-calculation deciding value which represents a ratio between a total number of the halftone dots in a neighboring area and the number of the halftone dots having a similarity of feature being smaller than a predetermined threshold value in the neighboring area. The re-calculation deciding unit decides whether the threshold value should be changed in order to decide necessity of change of the number of dots based on the re-calculation deciding value.
