PROBLEM TO BE SOLVED: To suppress noise caused by an optical correction means when hand shake is corrected by arithmetically operating specified information for suppressing the noise caused by the correction means by using an arithmetic operation means and correcting the blurring of an image based on the calculated result by the correction means. SOLUTION: By an angular velocity sensor 11, the shaked amount of a video camera is detected as angular velocity. The angular velocity is amplified by an amplifier part 12 and transmitted to an A/D converter 13 as a signal. By the A/D converter 13, the signal is sampled and transmitted to a microcomputer 21 as an angular velocity sampling value. By the microcomputer 21, a shift lens target position required for optimally correcting the hand shake according to a zoom position is calculated based on the angular velocity sampling value and the focal distance of a lens transmitted from a lens unit 41. By a servo circuit 31, the driving voltage of a level corresponding to difference between the shift lens target position transmitted from the microcomputer 21 and a shift lens position transmitted from a shift unit 42 is transmitted to the unit 42. |
