Title (EN) METHOD FOR TRANSMITTING DATA IN CAMERA MODULE
(FR) PROCÉDÉ DE TRANSMISSION DE DONNÉES DANS UN MODULE DE CAMÉRA
(KO) 카메라 모듈에서의 데이터 전송방법
Abstract:
(EN) The present invention relates to a method for transmitting data in a camera module which transmits data necessary for camera shake correction, and the present invention comprises a first step in which each actuator movement detection element sequentially transmits the axial movement distance detection data detected through a Hall sensor in a two-wire interface manner without correction after each specified time delay, in a first transmission section in which each piece of axial movement distance detection data of the actuator has to be transmitted to a controller module for a shake correction; and a second step in which each actuator movement detection element sets just the variation between previously transmitted axial movement distance detection data and currently detected axial movement distance detection data as each piece of axial movement distance detection data with respect to each axis and sequentially transmits in the two-wire interface manner after the same specified time delay, respectively, in a transmission section after the first transmission period.
(FR) La présente invention concerne un procédé de transmission de données dans un module de caméra qui transmet des données nécessaires à une correction de tremblement de caméra, et la présente invention comprend une première étape dans laquelle chaque élément de détection de mouvement d'actionneur transmet séquentiellement des données de détection de distance de mouvement axial détectées par l'intermédiaire d'un capteur à effet Hall d'une manière de type interface à deux fils sans correction après chaque retard temporel spécifié, dans une première section de transmission dans laquelle chaque élément de données de détection de distance de mouvement axial de l'actionneur doit être transmis à un module de commande en vue d'une correction de tremblement ; et une seconde étape dans laquelle chaque élément de détection de mouvement d'actionneur définit uniquement la variation entre des données de détection de distance de mouvement axial précédemment transmises et des données de détection de distance de mouvement axial actuellement détectées en tant que chaque élément de données de détection de distance de mouvement axial par rapport à chaque axe, et effectue une transmission séquentielle de la manière de type interface à deux fils après le même retard temporel spécifié, respectivement, dans une section de transmission après la première période de transmission.
(KO) 본 발명은 카메라 손떨림 보정을 위해 필요한 데이터를 전송하는 카메라 모듈에서의 데이터 전송방법에 관한 것으로, 액츄에이터의 각 축방향 이동거리 감지 데이터를 손떨림 보정용 컨트롤러 모듈로 전송해야 하는 첫 번째 전송구간에서는 상기 액츄에이터 이동감지 소자들 각각이 홀 센서를 통해 감지한 축방향 이동거리 감지 데이터를 수정 없이 각각 지정시간 지연 후 순차적으로 투-와이어 인터페이스 방식으로 전송하는 제1단계와, 상기 첫 번째 전송구간 이후의 전송구간에서 상기 액츄에이터 이동감지 소자 각각은 각 축에 대해 이전에 전송한 축방향 이동거리 감지 데이터와 현재 감지한 축방향 이동거리 감지 데이터와의 증감분만을 각 축방향 이동거리 감지 데이터로 설정하여 각각 지정시간 지연 후 순차적으로 투-와이어 인터페이스 방식으로 전송하는 제2단계:를 포함함을 특징으로 한다.
