ABSTRACT:
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.
