10. A camera comprising:
-
a camera lens;
a DC motor coupled with the camera lens to move the camera lens; and
a back EMF encoder coupled with the DC motor to receive a signal from the DC motor and to detect a position of the DC motor based on a number of transitions of the received signal. - View Dependent Claims (11, 12)

13. A camera comprising:
-
a camera lens;
a DC motor coupled with the camera lens to move the camera lens;
a sensor configured to track a subject; and
a controller coupled with the motor to control the motor and to the sensor to receive position information of the subject being tracked;
wherein the controller is configured to control movement of the motor based on the position information received from the sensor, the position information including a target position at which the subject stops; and
wherein the controller is configured to reverse a polarity of the DC motor before the camera lens reaches the target position to slow movement of the camera lens and avoid overshooting the target position. - View Dependent Claims (14, 15, 16)

17. A method of operating a camera, the method comprising:
-
moving a camera lens of a camera in pan movement to measure pan limit positions in pan movement;
moving the camera lens in tilt movement to measure tilt limit positions in tilt movement; and
automatically moving the camera lens to a home position with respect to the pan limit positions and the tilt limit positions upon initial start-up of the camera. - View Dependent Claims (18, 19)

20. A method of operating a camera, the method comprising:
-
determining a calibration offset for positioning a camera lens of a camera;
storing the calibration offset; and
using the calibration offset as a correction to control movement of the camera lens in pan and tilt to improve position accuracy of the camera lens. - View Dependent Claims (21, 22)
