Abstract

A security camera and a method of controlling auto-focusing of the security camera. The security camera continuously performs auto-focusing during a period of time, from the time of power-on and the start of a boot sequence until the time of completion of the camera installation, and stops the auto-focusing thereafter. Accordingly, it is possible to improve the durability of a camera mechanical system and to achieve easy installation and manipulation of the camera.

Claims

1. A security camera comprising:

an initial auto-focusing (AF) setting unit configured to continuously perform auto-focusing during a predetermined period of time, from a time of power on and start of a boot sequence until a time of completion of installation of the security camera, and stop the auto-focusing after the completion of installation.

2. The security camera of claim 1, further comprising:

a pan-tilt (PT)/auto-focusing (AF) setting unit configured to perform further auto-focusing in response to an PT operation.

3. The security camera of claim 1, additionally performing auto-focusing in response to a clapping sound and stopping the auto-focusing thereafter.

4. A method for controlling auto-focusing of a security camera, the method comprising:

executing a boot sequence upon power-on; and

performing auto-focusing for a predetermined period of time for which the security camera is installed and stopping the auto-focusing after the installation is completed.

5. The method of claim 4, further comprising:

detecting a pan-tilt operation; and

performing auto-focusing in response to the detected pan-tilt operation and stopping the auto-focusing thereafter.
