<p>PURPOSE:To eliminate the offset of a signal judged as camera shake at each time and to highly, exactly and accurately detect the ratio of the effective component of the signal by positively taking the offset by a high pass filter in the case the camera shake is large and making a camera shake detecting frequency band wide in the case the camera shake is small. CONSTITUTION:This camera shake detecting device 11 is constituted of a camera shake sensor part 12, an HPF arithmetic part 13 removing the drift and offset components of the sensor part 12, an HPF large signal decision part 111 detecting the large shake signal state based on output from the arithmetic part 13, a small time constant resetting part 15 shifting an upper limited frequency for removing the signal of the arithmetic part 13 to a high frequency side in the case the decision part 14 detects large shake, and a time constant enlarging part 16 shifting the upper limited frequency for removing the signal of the arithmetic part 13 from the high frequency side to a low frequency side.</p> |
