The present invention provides an image processing apparatus including a first recognition component, a second recognition component and a conversion component. The first recognition component recognizes input side unevenness information representing unevenness of an image depending on an image inputting apparatus to which an image inputted and image data representing an image inputted to the image inputting apparatus. The second recognition component recognizes output side unevenness information representing unevenness of an image depending on an image outputting apparatus outputting based on the image data. The conversion component, based on the input side unevenness information recognized by the first recognition component and the output side unevenness information recognized by the second recognition component, corrects unevenness of images on both sides and converts the image data to a format processable by the image outputting apparatus at an output destination.
