Ce module d'appareil de prise de vues a une fonction de mise au point automatique (AF) grâce à l'entraînement de l'objectif dans la direction de l'axe optique (axe z), et il a une fonction de stabilisation d'image optique (OIS) grâce à l'entraînement de l'objectif sur un plan (plan x-y) perpendiculaire à l'axe optique (axe z). Ledit module d'appareil de prise de vues comprend : une base qui possède des rainures d'insertion dans chaque direction angulaire de sa surface inférieure, et qui a des surfaces latérales ouvertes ; des éléments bobines OIS qui sont insérés dans les rainures d'insertion de la base et qui sont enroulés sur le plan x-y ; une protection qui est située sur la base ayant des surfaces latérales ouvertes, et qui présente à l'intérieur une partie espace ; un support qui possède un élément bobine AF enroulé autour de sa circonférence extérieure, et qui a un module d'objectif inséré à l'intérieur et disposé dans la partie espace de la protection de manière à être mobile dans la direction de l'axe optique ; des aimants fixés sur les surfaces latérales ouvertes de la protection et magnétisés respectivement de façon à avoir des polarités différentes à l'intérieur et à l'extérieur de cette protection ; ainsi qu'un élément élastique en forme de crochet conçu pour supporter élastiquement ladite protection à l'emplacement de la base, grâce à l'insertion d'une extrémité de cet élément dans la surface supérieure de la protection, et grâce au couplage de l'autre extrémité dudit élément avec la surface inférieure de la base.
