Abstract

An electronic image filing method includes a face image registration phase and an image arranging phase. The face image registration phase contains steps of: inputting a registration image; determining a characteristic quantity for a face in a face image contained in the registration image; and storing the characteristic quantity as a registered face image. The image arranging phase contains steps of: inputting a arranging target image; determining a characteristic quantity of a face in a face image in the arranging target image; detecting a registered face image among registered face images with a characteristic quantity matching the characteristic quantity of the face in the arranging target image having been determined; and correlating the arranging target image with the registered face image having been detected.
