Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a shake correcting device capable of easily coping with the miniaturization of a video camera and easily improving the degree of freedom in the design of the video camera. SOLUTION: Shake detecting sensors 330 and 340, BPFs(band-pass filters) 371 and 372, A/D conversion parts 373 and 374 and shake angle arithmetic operation parts 1a and 2a detect the shake of the video camera. Shake conversion parts 3a and 4a converts the detected shake into the shake in a camera shake correcting direction. Optical axis angle detecting sensors 350 and 360, LPFs(low-pass filters) 375 and 376, A/D conversion parts 377 and 378, adders 5a and 6a, PID control parts 7a and 9a and driving parts 380 and 381 control the posture position of the optical elements of optical element mechanisms 310 and 320 so as to control a transmission optical axis angle. |
