Abstract

Selon l'invention, pour fournir une technique qui permette à un utilisateur d'empêcher efficacement un échec de prise de vues et l'omission d'une image mobile souhaitée, le codeur d'image mobile 11 génère des données d'image mobile divisées en lesquelles des données sont divisées, en utilisant un nombre prédéterminé de trames comme unité, sur la base d'un signal d'imagerie entré à partir d'un endoscope 2. Une carte CF 12 possède une capacité d'enregistrement correspondant à une pluralité des unités de trame et peut enregistrer des données d'image mobile divisées par chaque unité de division. Une unité centrale de traitement (CPU) 13 enregistre séquentiellement les données d'image mobile divisées dans une série chronologique, et, lorsque des données d'image mobile divisées ayant une quantité dépassant la pluralité des unités de trame sont entrées dans la carte CF 12, la CPU 13 enregistre les dernières données d'image mobile divisées dans une région dans laquelle les plus anciennes données de la série chronologique sont stockées. La CPU 13, lors de la fourniture des données d'image mobile à un dispositif externe, lit les données d'image mobile divisées dans l'ordre provenant de la carte CF 12, rétroactivement par un nombre prédéterminé de trames, les combine pour générer des données d'image mobile combinées et fournit les données d'image mobile combinées au dispositif externe.
