SHAKE DETECTION DEVICE AND SHAKE DETECTION METHOD

PROBLEM TO BE SOLVED: To perform shake detection in which a swing-back component generated when finishing panning is prevented from being erroneously detected as shake. SOLUTION: An output signal HPF (Fig.9 (b)) from an X gyro sensor 50, whose low frequency component is removed by a high-pass filter...

Zusammenfassung:	PROBLEM TO BE SOLVED: To perform shake detection in which a swing-back component generated when finishing panning is prevented from being erroneously detected as shake. SOLUTION: An output signal HPF (Fig.9 (b)) from an X gyro sensor 50, whose low frequency component is removed by a high-pass filter 51, and an inversion signal -LPF (Fig.9 (d)) of a signal obtained by integrating the signal by an integrator 75 are determined in a determination part 76. When the signal in Fig.9 (b) is larger than A and the signal in Fig.9 (d) is larger than B (t6to t7), and the signal in Fig.9 (b) is smaller than -A and the signal in Fig.9 (d) is smaller than -B (t2to t3), the output signal is set to HPF+LPF, otherwise the output signal is set to HPF.
