Claim:
An image processing apparatus, having an image inputting section for inputting image data, saddle stitches respective quires that are made by folding print mediums and processes image data for binding a plurality of quires into a quire book, each quire having a plurality of pages, the image processing apparatus comprising: a setting section that sets a quire page-count of each quire; a size obtaining section that obtains medium size information of the print mediums; an assigning and obtaining section that assigns respective quire-book page number to each page of the inputted image data, and obtains an image page-count; a page calculating section that calculates a quire-book page-count on the basis of the quire page-count and the image page-count; a determining section that respectively determines a print region corresponding to the respective quire-book page number on the basis of the quire page-count, the medium size information and the quire-book page-count; and a changing section that respectively changes each page of the image data to change image data scaled to fit within the print region determined with respect to the corresponding quire-book page number, wherein a first binding margin value is determined by the determining section based on a quire page number in a single quire, a second binding margin value is determined by the determining section based on the quire-book page number, and a binding margin value corresponding to each quire-book page number is calculated by the determining section based on the first and second binding margin values, and wherein the first and second binding margin values in odd-numbered pages and the first and second binding margin values in even-numbered pages are calculated by the determining section using different formulae respectively.
