ABSTRACT:
In a camera having a function of correcting a shake, a value of angular velocity or of velocity output from a sensor for detecting the shake is differentiated twice to obtain the differential value of the angular acceleration or the acceleration. When the resultant differential value of the angular acceleration or the acceleration is equal to 0, the angular velocity or the velocity is considered to be equal to 0. According to the obtained angular velocity or the velocity, the velocity or the angular velocity of the sensor for detecting the shake is corrected.
