DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Embodiments of the present invention will be described with reference to FIGS. 1 to 12. The present invention, however, should not be construed as being Limited to the embodiments described herein. These embodiments should be considered as only examples of the present invention.
As referring to FIG. 1 to FIG. 9, a method for controlling a surveillance camera in which a surveillance camera 2 is remotely controlled by a mobile device 1 according to an embodiment of the present invention, includes steps as follows: enabling the mobile device 1 to perform an operational motion (step S10); and enabling a camera lens 20 of the surveillance camera 2 to perform an operational action corresponding to the operational motion of the mobile device 1 (step S20), wherein the operational motion includes: an upward/downward position movement, a leftward/rightward position movement, a forward/backward position movement, a left/right inclining movement, a forward/backward inclining movement, a left/right rotating movement, a shaking movement, a tracking movement, and a combination thereof. Further, the operational action includes operation of a turning, a rotating, a position movement, a focus adjusting, and/or a photographing for the camera lens 20.
As referring to FIG. 2, the mobile device 1 in an embodiment is a smart phone. Of course, the present invention is not limited to this and the mobile device may be a table computer or a portable smart device. The surveillance camera 2 is remotely controlled by the mobile device 1 through a wireless communication or a wired communication, wherein the wireless communication is a Bluetooth communication, a Wi-Fi communication, a 3G communication, or a 4G communication.
Via the method for controlling a surveillance camera of the present invention, a user can hold the mobile device 1 to perform various operational motions that includes an upward/downward position movement, a leftward/rightward position movement, a forward/backward position movement, a left/right inclining movement, a forward/backward inclining movement, a left/right rotating movement, a shaking movement, a tracking movement, and a combination thereof. Therefore, a user can remotely control the camera lens 20 of the surveillance camera 2 to perform a turning, a rotating, a position movement, a focus adjusting, and/or a photographing. Accordingly, the method for controlling a surveillance camera of the present invention utilizes a more intuitive operational motion than the conventional method, thus making it unnecessary to use a joystick, a button or a touch screen. Several embodiments with respect to an operational motion and its corresponding operational action for the surveillance camera will be described as follows.
As referring to FIG. 2 to FIG. 4, when the operational motion is a leftward/rightward position movement as shown in FIG. 2, a left/right inclining movement as shown in FIG. 3, or a left/right rotating movement as shown in FIG. 4, then the operational action is a left/right turn for the camera lens 20 in correspondence to the operational motion. As referring to FIG. 5 and FIG. 6, when the operational motion is an upward/downward position movement as shown in FIG. 5, or a forward/backward inclining movement as shown in FIG. 6, then the operational action is an up/down turning for the camera lens 20 in correspondence to the operational motion. As referring to FIG. 7 and FIG. 8, when the operational motion is a forward/backward position movement as shown in FIG. 7, or a forward/backward inclining movement as shown in FIG. 8, then the operational action is a focus adjusting for the camera lens 20 in correspondence to the operational motion. As referring to FIG. 9, when the operational motion is a tracking movement along with a circle path, the operational action is a focus adjusting for the camera lens 20. For example as a detail, a clockwise circle path corresponds to a zoom-in operation for the camera lens 20, and a counterclockwise circle path corresponds to a zoom-out operation for the camera lens 20. As referring to FIG. 10, when the operational motion is a left/right rotating movement, then the operational action is a left/right rotation for the camera lens 20. Further, when the operational motion is the shaking movement, i.e., a quick upward/downward positional movement, a quick leftward/rightward positional movement, and a quick forward/backward positional movement, then the operational action is a photographing for the camera lens 20 in correspondence to the operational motion. Furthermore, when the operational motion is an upward/downward position movement, a leftward/rightward position movement, or a forward/backward position movement, then the operational action is an upward/downward position movement, a leftward/rightward position movement, or a forward/backward position movement for the camera lens 20 (not shown in the figures). However, the present invention is not limited to this. The operational action can be an action of calling a setup menu, a recording status such as a status of the current turning angle, the current rotation angle and a focus length of the camera lens. The operational action can also be an action of starting or stopping recording, or adjusting a recording parameter such as frames per second or an aperture size. Further, a corresponding relationship between the operational motion and the operational action may be defined by a user.
As referring to FIG. 11 and FIG. 12, the step S20 further includes the steps as follows. A motion detecting module 11 of the mobile deice 1 detects the operational motion and generates a motion control signal (step S21). Then a first communication module 12 of the mobile device 1 transmits the motion control signal to a second communication module 21 of the surveillance camera 2 (step S22), and the second communication module 21 transmits the motion control signal to an operational action module 22 so as to utilize the camera lens 20 to perform an operational action (step S23). A monitoring image and/or a recording status of the camera lens 20 then is synchronously transmitted to the first communication module 12 by the second communication module 21 so that a display screen of the mobile device 1 can synchronously display the monitoring image and/or the mobile device can synchronously receive the recording status (step S30), wherein the recording status includes at least one of a turning angle, a rotation angle and a focus of the camera lens 2. After step S30, previous step may be repeated for a continuous control depending on various different situations.
Therefore, as referring to FIG. 3, when a user holds the mobile device to perform a right inclining movement, then the surveillance camera 2 is remotely controlled to turn right, and a monitoring image being turned right is synchronously displayed on the display screen of the mobile device 1. In other words, the display screen of the mobile device 1 provides a real visual effect to a user in a way that a user can immediately see? the monitoring image transmitted from the surveillance camera 2, and thus a user can more intuitively control the surveillance camera 2. Accordingly, the method for controlling a surveillance camera of the present invention is free from touching a joystick or a touch screen, and studying a touch screen gesture is not needed, making the operation simpler as compared with a conventional method.
As referring to FIG. 12, a system for controlling a surveillance camera 100 according to the embodiment of the present invention includes a mobile device 1 and a surveillance camera 2, wherein the mobile device 1 employs the method for controlling a surveillance camera of the present invention to remotely control the surveillance camera 2.
As referring to FIG. 12, the mobile device 1 includes a motion detecting module 11. The motion detecting module 11 includes one or more items selected from a group including a six-axis sensor, an accelerometer, and a gyroscope. The motion detecting module 11 can detect an upward/downward position movement, a leftward/rightward position movement, a forward/backward position movement, a left/right inclining movement, a forward/backward inclining movement, a left/right rotating movement of the mobile device 1. The mobile device 1 has a processor 13 that can analyze that the mobile device 1 is in a shaking movement or is in a particular tracking movement.
As referring to FIG. 12, the mobile device 1 includes a first communication module 12, and the surveillance camera 2 includes a second communication module 21 that is remotely communicating with the second communication module 21.
Further, the system for controlling a surveillance camera 100 according to the embodiments of the present invention can be operated by software. For example, it is popular that a smart phone executes a mobile application, i.e., APP, to utilize a motion detecting module installed in the smart phone to detect an operational motion of the smart phone, and then the smart phone transmits a motion control signal to the surveillance camera to remotely control the surveillance camera. Therefore, the system for controlling a surveillance camera 100 according to the embodiment of the present invention can be easily applied to various mobile devices such as a smart phone or a table computer, or applied to a surveillance camera that has a remote controlling function. However, a hardware change on the mobile device or on the surveillance camera is not needed. Therefore, a user can easily and conveniently control the surveillance camera.
The above description should be considered as only a discussion of the preferred embodiments of the present invention. However, a person skilled in the art may make various modifications to the present invention. Those modifications still fall within the spirit and scope as defined by the appended claims.
