Abstract
(EN) The present application relates to a focusing method and apparatus, a computer readable storage medium, and a mobile terminal. The method comprises: acquiring a focal length corresponding to the lens position when a first camera is in focus; acquiring the lens position when a second camera corresponding to the focal length is in focus; and driving the lens of the second camera to reach the lens position of the second camera when in focus, and performing focusing. In the present method, after focusing of the primary camera is complete, the focal length of the primary camera is acquired, the lens position of a corresponding secondary camera when in focus is found on the basis of the focal length of the primary camera, and the secondary camera is driven to reach the corresponding lens position and complete focusing, thus improving the accuracy of dual camera focusing, and making dual camera focusing more convenient.
(FR) La présente invention concerne un procédé et un appareil de mise au point, un support de stockage lisible par ordinateur, et un terminal mobile. Le procédé consiste à : acquérir une longueur focale correspondant à la position d’objectif lorsqu'un premier appareil photo fait une mise au point ; acquérir la position d’objectif lorsqu'un second appareil photo correspondant à la longueur focale fait une mise au point ; et entraîner l’objectif du second appareil photo de sorte qu’il atteigne la position d’objectif du second appareil photo lorsqu'il fait une mise au point, et exécuter une mise au point. Dans le procédé selon l’invention, une fois la mise au point de l’appareil photo primaire accomplie, la longueur focale de de l’appareil photo primaire est acquise, la position d’objectif d'un appareil photo secondaire correspondant lorsqu'il fait une mise au point est trouvée sur la base de la distance focale de l’appareil photo primaire, et l’appareil photo secondaire est entraîné de sorte à atteindre la position d’objectif correspondante et à accomplir la mise au point, ce qui améliore la précision de mise au point des deux appareils photo et facilite la mise au point des deux appareils photo.
(ZH) 本申请涉及一种对焦方法、装置、计算机可读存储介质和移动终端。上述方法包括:获取第一摄像头合焦时镜头位置对应的合焦距离;获取所述合焦距离对应的第二摄像头合焦时镜头位置;驱动第二摄像头的镜头到达所述第二摄像头合焦时镜头位置并进行对焦。上述方法,在主摄像头对焦完成后,获取主摄像头的合焦距离,再根据主摄像头的合焦距离查找对应的副摄像头的合焦时镜头位置,并驱动副摄像头到达对应的镜头位置完成对焦,提高了双摄对焦的准确性,双摄对焦更加便捷。
