Title:
PHOTOGRAPHING DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/188902
Kind Code:
A1
Abstract:
A photographing device and a control method therefor for obtaining an optical low-pass-filter effect by driving a movement member (shaking correction member) in a direction different from the optical axis of a photographing optical system, wherein the drive of the movement member (shaking correction member) is controlled with high accuracy, and high-frequency noise is prevented from being generated and imparting discomfort to a user. When an exposure time determination unit determines that an exposure time set by an exposure time setting unit is longer than a critical time, a drive control unit drives the movement member via a drive mechanism on the basis of a low-frequency drive signal generated by a low-frequency drive signal generation unit. When the exposure time determination unit determines that the exposure time set by the exposure time setting unit is shorter than the critical time, the drive control unit drives the movement member via the drive mechanism on the basis of a high-frequency drive signal generated by a high-frequency drive signal generation unit.
