Image processing apparatus having improved function for creating image using a plurality of original images

An image reading unit reads a plurality of original images so as to provide the corresponding image information. An input size specifying unit specifies input sizes according to which the image reading unit respectively reads the plurality of original images so that the resulting image information represents the specified input sizes of the plurality of original images, wherein the input sizes may be identical to one another. A first storing unit stores the resulting image information therein. A first image indicating unit indicates the image represented by the image information stored in the first storing unit. A image processing unit appropriately processes the image information stored in the first storing unit so as to create image information representing at least one finished image. An output size specifying unit specifies an output size according to which the image processing unit processes the image information so that the finished image has the specified output size. A second storing unit stores the image information representing the finished image therein. A second image indicating unit indicates the finished image using the corresponding image information stored in the second storing unit. A recording unit records the image information representing the finished image on a recording medium after extracting the image information from the second storing unit.
