Abstract

Par rapport à un réfrigérateur conçu pour capturer une image de l'intérieur du réfrigérateur et de la fournir, le but de la présente invention est d'empêcher des images sombres ayant une mauvaise visibilité d'être capturées lorsque l'intérieur du réfrigérateur est dans un état sombre. Ce réfrigérateur comprend: une unité de détection de luminosité qui détecte la luminosité à l'intérieur d'une unité de stockage irradiée avec de la lumière par une source de lumière tandis que la porte du corps de réfrigérateur est fermée; et une unité de restriction d'imagerie qui limite la capture d'images par une caméra si la luminosité à l'intérieur du réfrigérateur détectée par l'unité de détection de luminosité est faible. Ainsi, il est possible d'empêcher des images sombres ayant une mauvaise visibilité d'être capturées lorsque l'intérieur du réfrigérateur est dans un état sombre.
