Abstract

La présente invention concerne des procédés et systèmes pour mettre en œuvre un moteur d’imagerie miniature à longue portée avec mise au point automatique, zoom automatique et éclairage automatique. Un exemple de procédé comporte la détection, par un microprocesseur, de la présence d’un motif lumineux de visée dans le FOV ; la détermination, par le microprocesseur et en réponse à la détection, d’une distance cible d’un objet dans le FOV sur la base d’une position du motif lumineux de visée dans le FOV, la distance cible étant une distance entre le moteur d’imagerie et l’objet ; la provocation, par le microprocesseur, d’une mise au point par un élément optique à focale variable sur l’objet sur la base de la distance cible ; en réponse à la réalisation d’une première détermination par le microprocesseur, la sélection, sur la base de la distance cible, d’un mode de fonctionnement de zoom parmi une pluralité de modes de fonctionnement de zoom ; et en réponse à la réalisation d’une deuxième détermination par le microprocesseur, la sélection, sur la base de la distance cible, d’un mode d’éclairage parmi une pluralité de modes d’éclairage.
