Abstract
In an image processing method, a direction transforming process is performed on an image signal representing an image and in accordance with information giving specifics about an image recording technique. In cases where a marker pattern, which is represented by a marker signal, is to be appended to the image represented by the image signal, the direction and the appending position of the marker signal are determined in accordance with the information giving specifics about the image recording technique. The marker signal is appended to the image signal in accordance with the thus determined direction and the thus determined appending position of the marker signal. The marker signal is thus appended to the image signal in an appropriate state in accordance with the specifics about the image recording technique.
