AI Technical Summary
Technical Problem
Existing camera systems face issues with improper pan angle control and high power consumption when installed in non-ideal orientations, leading to motor overload and potential loss of step due to varying installation conditions.
Method used
A camera system with a drive control unit that recognizes the inclination angle of the pan axis relative to the vertical direction, adjusting the drive current of the pan axis motor based on the tilt angle to ensure proper control and reduce power consumption.
Benefits of technology
Enables precise control of the camera's field of view even in non-ideal installations, preventing motor overload and reducing power consumption by dynamically adjusting the drive current based on the tilt angle.

Abstract
Even if there is a deviation from the ideal installation conditions, the camera's field of view will be properly controlled. [Solution] The drive control unit 41 controls the pan axis motor 42 and tilt axis motor 43 to achieve the desired pan angle and tilt angle based on control signals input from an external source. To control these motors, a pan axis driver 44 and a tilt axis driver 45 are provided, respectively, which generate and output pulse signals to be input to them, and these are controlled by the drive control unit 41. The tilt sensor 46 recognizes its tilt angle from the vertical. This tilt angle is the tilt angle of the pan axis from the vertical. If this tilt angle is large, the drive control unit 41 controls the pan axis driver 44 so that the drive current of the pan axis motor 42 increases.
