Abstract:
(EN) The present invention relates to an image stabilization control device for an imaging device, the image stabilization control device stabilizing the shaking, of a subject, caused by vibration applied to an imaging device, and comprising: filters for outputting rotational angular speed data in which a low-frequency component is removed from a rotational angular speed outputted from each of vibration detection sensors of an imaging device according to filter coefficients, which are variably set; a lens moving distance calculation unit processing output signals of the filters so as to calculate a lens moving distance; and a filter coefficient variable control unit for varying the filter coefficients of the filters in order to increase a lens return speed in a lens movement limit area, when the lens moving distance outputted from the lens moving distance calculation unit goes beyond the lens movement limit area having been virtually set.
(FR) La présente invention concerne un dispositif de contrôle de stabilisation d'image pour un dispositif d'imagerie, le dispositif de contrôle de stabilisation d'image stabilisant l'agitation, d'un sujet, provoquée par une vibration appliquée à un dispositif d'imagerie. Le dispositif comprend : des filtres pour délivrer en sortie des données de vitesse angulaire de rotation, dans lesquelles une composante basse fréquence est supprimée d’une vitesse angulaire de rotation délivrée en sortie depuis chacun des capteurs de détection de vibration d'un dispositif d'imagerie, selon des coefficients de filtre qui sont définis de manière variable ; une unité de calcul de distance de déplacement d’objectif, qui traite des signaux de sortie des filtres de sorte à calculer une distance de déplacement d’objectif ; et une unité de contrôle de variable de coefficient de filtre, pour faire varier les coefficients de filtre des filtres afin d'augmenter une vitesse de retour d’objectif dans une zone de limite de mouvement d’objectif lorsque la distance de déplacement d’objectif délivrée par l'unité de calcul de distance de déplacement d’objectif dépasse la zone de limite de mouvement d’objectif qui a été virtuellement définie.
(KO) 본 발명은 촬상장치에 가해지는 진동에 의한 피사체의 흔들림을 안정화시키는 촬상장치의 이미지 안정화 제어장치에 관한 것으로, 가변 설정되는 필터 계수에 따라 촬상장치의 진동검출 센서들 각각으로부터 출력되는 회전 각속도에서 저주파 성분을 제거한 회전 각속도 데이터를 출력하는 필터들과, 상기 필터들의 출력신호를 처리하여 렌즈 이동거리를 계산하는 렌즈 이동거리 계산부와, 상기 렌즈 이동거리 계산부로부터 출력되는 렌즈 이동거리가 가상 규정된 렌즈이동 제한영역을 벗어날 경우 렌즈이동 제한영역 내로의 렌즈 복귀속도를 높이기 위해 상기 필터들의 필터 계수를 가변시키는 필터 계수 가변 제어부를 포함함을 특징으로 한다.
