1. A method of processing image data, comprising the steps of:
storing calibration pattern data in a first apparatus;
sending the calibration pattern data from the first apparatus to a second apparatus to allow generation of a calibration pattern image in the second apparatus;
generating the calibration pattern image in the second apparatus using an image printer apparatus according to the calibration pattern data;
combining a plurality of images of a subject object and the calibration pattern image by an image recording device at different relative orientations;
recording combined image data defining the combined images;
sending the combined image data to the first apparatus; and
performing processing in the first apparatus on the basis of the stored calibration pattern data and the sent combined image data to calculate the orientations at which at least some of the images were recorded.
