Abstract

Lorsque la méthode de reconnaissance de zone vide d'une unité de contrôle de système (166) découvre que des données miniatures doivent être stockées dans une unité de stockage d'image d'une mémoire (165) par une méthode de traitement du stockage, un appareil de reproduction/d'enregistrement (100) décide s'il existe une zone vide dans l'unité de stockage d'images. Lorsque le système de reconnaissance de zone vide juge qu'il n'existe pas de zone vide, l'unité de contrôle du système (166) reconnaît la position en fonction de la hiérarchie des données miniatures et des données d'image en cache stockées dans l'unité de stockage d'images via une méthode de sélection des données à supprimer. La méthode de sélection des données à supprimer sélectionne pour effacement les données d'image du cache à la position de la structure hiérarchique, séparée de la position basée sur la hiérarchie des données miniatures. L'unité de contrôle du système (166) efface les données d'image du cache sélectionnées par la méthode de traitement de stockage et stocke les données miniatures sous forme de données d'image de cache.
