Abstract

La présente invention concerne un procédé de commande de caméra pour un terminal intelligent, comprenant les étapes suivantes : étape 1, activer un terminal intelligent, accéder à un OTP dans un capteur d'une caméra pour inscrire une valeur micrométrique et une valeur d'infini de la caméra, et les enregistrer dans un nœud de fichier ; étape 2, activer la camera ; étape 3, lire la valeur micrométrique et la valeur d'infini à partir du nœud de fichier ; et étape 4, diviser la valeur micrométrique et la valeur d'infini en un nombre souhaité de parties, et attribuer des valeurs des parties souhaitées à des valeurs clés de position de caméra d'un système du terminal intelligent. En utilisant la solution technique ci-dessus, la présente invention permet une acquisition automatisée précise de valeurs minimales et maximales correspondantes de chaque moteur de lentille, de façon à acquérir ainsi avec précision des valeurs de code de vues proches et distantes pour différentes caméras de terminaux intelligents.
