している。In the above-described surface shake correction device in the CCD camera device 13, the optical axis 5 from the subject 12 is not affected by the swing such as the hand shake in the X-axis and Y-axis directions.
The swing angle ± θ is set within one degree.
Moreover, the frequency component of the angular velocity signal V in which is detected as a surface deflection signal obtained from the sensor in X and Y-axis gyro 9 and 10 are distributed in the range of 0.5Hz to 30 Hz. On the other hand, the CCD camera device 13 is moved to the X axis (horizontal).
Panning operation to intentionally rotate in the direction, or Y
Even in the tilting operation for rotating in the axial (vertical) direction, the frequency components of the angular velocity signals (V in ) detected from the gyros 9 and 10 for the X and Y axes are distributed in the same frequency range. .

た。However, in a relatively fast panning or tilting operation, the output level becomes larger than the angular velocity signal at the time of surface shake such as hand shake. Therefore, if the frequency range and the level are detected, it is possible to intentionally discriminate the angular velocity signal of the fast pan or tilt operation. However, the frequency component and the level of the extremely slow (slow) pan or tilt operation are possible. Is substantially the same as the angular velocity signal at the time of surface shake such as camera shake, and thus there is a problem that detection by a filter or the like becomes impossible.
