Abstract
L'invention concerne un dispositif électronique portable équipé d'une caméra rotative (301) montée sur un petit arbre cylindrique (302) permettant la rotation d'une caméra dans au moins une direction autour de l'axe charnière. Une rotation de l'arbre par rotation des objectifs de 180° permet à l'angle de visualisation d'augmenter depuis l'avant vers l'arrière sans déplacer le panneau d'affichage. Un capteur d'inclinaison détermine l'angle de la caméra numérique et produit la commande correspondante, la focalisation est alors automatiquement réglée pour prendre une photo par mise au point automatique (AF), lorsque l'objectif détecte un objet, et, si nécessaire, fait tourner l'image qui est, ensuite, affichée sur l'écran à cristaux liquides.
