The present invention provides a technique capable of changing the image
capturing direction of a camera at high speed while suppressing noise
generated by resonance. At the time of changing the angle of the image
capturing direction of a surveillance camera from a base angle to a first
angle, if driving of both of a motor for panning and a motor for tilting
is simply started simultaneously and completed simultaneously, there is a
case such that the motor for panning generates resonance with the body of
the surveillance camera or the like and noise becomes too loud. In such a
case, the drive speed of the motor for panning, that is, the pulse rate
is shifted to a high speed side on which resonance does not generate and
the panning is finished first. Specifically, the angle of the image
capturing direction is changed from the base angle to a second angle and,
after that, changed from the second angle to the first angle.
