    • A shaking sensing unit includes a sensor sensing a rotation about at least one axis, a high pass filter passing only a signal having a frequency not less than a cutoff frequency of the high pass filter, among electrical signals output from the sensor, and a low pass filter passing only a signal having a frequency not greater than a cutoff frequency of the low pass filter and higher than the cutoff frequency of the high pass filter, among the electrical signals output from the sensor. The cutoff frequency of the high pass filter and the cutoff frequency of the low pass filter are variably determined according to a shaking frequency.
    • 振动感测单元包括感测来自传感器输出的电信号中的关于至少一个轴的旋转的传感器和仅具有频率不低于高通滤波器的截止频率的信号的高通滤波器,以及低通滤波器 在仅从传感器输出的电信号中通过频率不高于低通滤波器的截止频率的信号并高于高通滤波器的截止频率的信号。 根据振动频率可变地确定高通滤波器的截止频率和低通滤波器的截止频率。
