Abstract[English]
Provided is an optical image stabilization system and its control that can improve the compensation ability in the pan-tilt state. The optical image stabilization system comprises: a detection unit configured to detect motion of a compensation target object in each frame of a moving image, wherein the compensation target object is an optical system, a camera module or an image sensor; and a driver configured to perform compensation of blur of an image by moving the compensation target object so as to cancel the motion of the detected compensation target object. A period corresponding to each frame includes a first period during which exposure is carried out and a second period during which the exposure is suspended. The driver initiates the compensation so as to perform the compensation at least in part of the first period, and suspends the compensation so as not to perform the compensation at least in part of the second period.[French]
L'invention concerne un système de stabilisation d'image optique et sa commande qui peuvent améliorer la capacité de compensation dans l'état de panoramique-inclinaison. Le système de stabilisation d'image optique comprend : une unité de détection configurée pour détecter un mouvement d'un objet cible de compensation dans chaque trame d'une image animée, l'objet cible de compensation étant un système optique, un module de caméra ou un capteur d'image ; et un pilote configuré pour effectuer une compensation de flou d'une image par déplacement de l'objet cible de compensation de façon à annuler le mouvement de l'objet cible de compensation détecté. Une période correspondant à chaque trame comprend une première période pendant laquelle une exposition est effectuée et une seconde période pendant laquelle l'exposition est suspendue. Le pilote lance la compensation de façon à effectuer la compensation au moins en partie de la première période, et suspend la compensation de façon à ne pas effectuer la compensation au moins en partie de la seconde période.
