Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/141193
Kind Code:
A1
Abstract:
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).
