This invention has as its object to allow an authentication process that avoids unnecessary information from being stored in a digital camera irrespective of whether or not a digital camera connected to the printer has a direct print function. To this end, in this invention, in an early stage of connection between a digital camera DSC and PD printer, the PD printer side requests an object which contains a keyword as authentication information of those which are stored and held by the DSC (S29). As a result, after it is determined the returned information contains authentication information, the printer notifies the DSC of its own authentication information (S33).
La présente invention à pour objectif la réalisation d'une procédure d'authentification permettant d'éviter la mémorisation d'une information inutile dans une caméra numérique indépendamment de la connexion ou non de la caméra à l'imprimante qui présente une fonction d'impression directe. A cet effet, dans la présente invention, lors d'une étape anticipée de connexion entre la caméra numérique et une imprimante à report direct, la section d'imprimante à report direct demande un objet qui contient un mot-clé comme information d'authentification de ceux qui sont mémorisés et contenus dans la caméra numérique (S29). Par conséquent, lorsqu'il est déterminé que l'information retour contient une information d'identification, l'imprimante signale à la caméra sa propre information d'authentification (S33).
