    • Featured are an image processing apparatus, method and a medium including an image processing program. The image processing apparatus includes an image inputting means for inputting front and back images of an original, an image reversing means for reversing one of the front and back images, a position relationship detection means, image correcting means and image outputting means for outputting the image. The positional relationship detecting means detects the positional relationship between the front image reversed by the image reversing means and the back image from the image inputting means or the positional relationship between the back image reversed by the image reversing means and the front image from the image inputting means. The image correcting means corrects the image to eliminate a ghost image of the image using the positional relationship between the front and back images obtained from the positional relationship detecting means.

    • In order to the monochromatic conversion of an image, in an image processing apparatus (1a), the color used within the image inputted from an image inputting section (2) is determined by a color analyzing section (3), the mixing-ratio of the color components of the image is defined based on the color by a mixing-ratio calculating section (4), the color components are mixed according to the mixing-ratio by an image converting section (5) thereby converting the input image to a monochromatic image, and it is outputted from an image outputting section (6). Further, in order to contract an composite image comprising a character, a line drawing, and a halftone dot, an image processing apparatus (21a) comprises an image inputting section (22), a character/line drawing region extracting section (23) for an input image, a pseudo-density region extracting section (24) for the input image, an image contracting section (25) for contracting the image using different methods respectively in the pseudo-density region, the character/line drawing region, and the other region, and an image outputting section (26) for outputting the image. Furthermore, in order to eliminate a ghost image, in an image processing apparatus (31a), front and back images are inputted from an image inputting section (32), an image reversing section (33a) reverses it, a positional relationship detecting section (34) detects the positional relationship, an image correcting section (35) corrects the image as to eliminate a ghost image, an image reversing section (33b) reverses it again, and an image outputting section (36). Further, in order to align the image position, in an image processing apparatus (50), the alignment of the images of the consecutive pages from among the images inputted page by page from the image inputting section (51) is carried out by a page contour detecting section (52), a page contents region extracting section (53), an inclination correcting section (54), and page information processing section (57), and it is outputted from the image outputting section (56).
