要約
(EN)
In order to correct accurately for a shaky hand even during operation of movable parts within an imaging device, an angular velocity sensor (14) detects the angular velocity (ω) when shaking of the hand occurs. A rotational angle calculation unit (45) integrates the angular velocity (ω) and detects the angular vibration (θ). A translational acceleration calculation unit (55) subtracts the internal acceleration generated during the driving of a lens device (11a) from a first translational acceleration (Acc1) detected by an acceleration sensor (15), and calculates a second translational acceleration (Acc2). A translational velocity calculation unit (57) integrates the second translational acceleration (Acc2) and calculates the translational velocity (V). A radius of rotation calculation unit (61) calculates the radius of rotation (R) from the angular velocity (ω) and the translational velocity (V). A vibration amount calculation unit (62) calculates the amount of vibration (δ) on the basis of the angular vibration (θ) and the radius of rotation (R). An actuator (23a) drives a vibration correction lens (23) so as to negate the amount of vibration (δ).

Selon la présente invention, afin de corriger de façon précise l'effet des mains tremblantes même pendant le fonctionnement de pièces mobiles dans un dispositif d'imagerie, un capteur de vitesse angulaire (14) détecte la vitesse angulaire (ω) lorsqu'un tremblement de la main se produit. Une unité de calcul de l'angle de rotation (45) intègre la vitesse angulaire (ω) et détecte les vibrations angulaires (θ). Une unité de calcul de l'accélération de translation (55) soustrait l'accélération interne générée pendant l'entraînement d'un dispositif de lentille (11a) d'une première accélération de translation (Acc1) détectée par un capteur d'accélération (15) et calcule une seconde accélération de translation (Acc2). Une unité de calcul de la vitesse de translation (57) intègre la seconde accélération de translation (Acc2) et calcule la vitesse de translation (V). Une unité de calcul du rayon de rotation (61) calcule le rayon de rotation (R) à partir de la vitesse angulaire (ω) et de la vitesse de translation (V). Une unité de calcul de la quantité de vibrations (62) calcule la quantité de vibrations (δ) sur la base des vibrations angulaires (θ) et du rayon de rotation (R). Un actionneur (23a) entraîne une lentille de correction des vibrations (23) de sorte à réduire les effets de la quantité des vibrations (δ).

 撮像装置内の可動部が作動中であっても正確に手振れ補正を行う。 手振れ発生時に、角速度センサ(14)は角速度(ω)を検出する。回転角算出部(45)は、角速度(ω)を積分して角度ブレ(θ)を算出する。並進加速度算出部(55)は、加速度センサ(15)で検出した第1並進加速度(Acc1)から、レンズ装置(11a)の駆動中に発生する内部加速度を減算して、第2並進加速度(Acc2)を算出する。並進速度算出部(57)と、第2並進加速度(Acc2)を積分して並進速度(V)を算出する。回転半径算出部(61)は、角速度(ω)と並進速度(V)から回転半径(R)を算出する。ブレ量算出部(62)は、角度ブレ(θ)と回転半径Rに基づいて、ブレ量δを算出する。アクチュエータ(23a)は、ブレ量δを打ち消す向きに、ブレ補正レンズ23を駆動する。
