Abstract

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.
