1. An image generating apparatus comprising: a composite image generating unit that generates a parent image having a plurality of composite sub-images, each of the sub-images being a combination of an image of an object to be printed onto a medium, an image containing coordinate address information for locating a position on the medium within the sub-image, and an image for address identification information; and a misalignment detection unit that detects a misalignment distance when a captured two-dimensional code image is out of a framed area within the parent image, and adjusts the coordinate information based on the detected misalignment, wherein the address identification information is printed as a group, in a first area, and the coordinate information is printed as another group, in a second area, the address identification information in the first area identifies the location of the coordinate information in the second area, the first and second areas are located in different locations on the medium, and the coordinate address information is based on a pattern used to create the sub-image.
