Abstract

A system is disclosed to adjusting a shooting angle of a camera lens. The system generates an electric signal relative to a contacting track of a touching device on a touch screen or a touch on the touch screen. The electric signal is processed to obtain a displacement of the touching device on the touch screen or a coordinate of the touch on the touch screen. A control signal is generated according to the displacement of the touching device on the touch screen or the coordinate of the touch on the touch screen. The system adjusts the shooting angle of the camera lens according to the control signal. Therefore, the camera lens captures images in a required area. The images captured by the camera lens may be displayed on the touch screen.

Claims

1. A system for adjusting a shooting angle of a camera lens, the system comprising:

an electronic device comprising a touch screen to convert a contacting track of a touching device on the touch screen into a first electric signal, or convert a touch on the touch screen into a second electric signal;

a processing unit;

a storage system connected to the processing unit and storing at least two modules to be executed by the processing unit, wherein the at least two modules comprise;

a calculating module to obtain a displacement of the touching device on the touch screen in response to receipt of the first electric signal, or obtain a coordinate of the touch on the touch screen in response to receipt of the second electric signal; and

a control module to output a first control signal in response to receipt of the displacement of the touching device, or output a second control signal in response to receipt of the coordinate of the touch; and

a driving unit to receive the first or second control signal, and adjust the shooting angle of the camera according to the first or second control signal, wherein the touch screen is operable to display images captured by the camera lens.

2. The system of claim 1, further comprising a signal receiving unit, wherein the driving unit receives the first or second control signal via the signal receiving unit.

3. The system of claim 2, wherein the signal receiving unit is an interface of the driving unit.

4. The system of claim 2, wherein the signal receiving unit is an antenna.

5. The system of claim 2, further comprising a network unit connected between the signal receiving unit and the storage system.

6. The system of claim 1, wherein the driving unit is a pan motor.

7. A system for adjusting a shooting angle of a camera lens, the system comprising:

an electronic device comprising a touch screen to display images captured by the camera lens, and generate an electric signal relative to a contacting track of a touching device on the touch screen or a touch on the touch screen;

a processing unit;

a storage system connected to the processing unit and storing a plurality of modules to be executed by the processing unit, wherein the plurality of modules comprises;

a calculating module to receive the electric signal, and thereby obtain a displacement of the touching device on the touch screen or a coordinate of the touch on the touch screen; and

a control module to receive the displacement or the coordinate, and output a control signal; and

a driving unit to adjust the shooting angle of the camera according to the control signal.

8. The system of claim 7, further comprising a signal receiving unit transmitting the control signal to the signal receiving unit.

9. The system of claim 8, wherein the signal receiving unit is an interface of the driving unit.

10. The system of claim 8, wherein the signal receiving unit is an antenna.

11. The system of claim 8, further comprising a network unit, wherein the signal receiving unit receives the control signal via the network unit.

12. The system of claim 7, wherein the driving unit is a pan motor.

13. An adjustment method comprising:

generating an electric signal relative to a contacting track of a touching device on a touch screen or a touch on the touch screen;

processing the electric signal to obtain a displacement of the touching device on the touch screen or a coordinate of the touch on the touch screen;

outputting a control signal according to the displacement of the touching device on the touch screen or the coordinate of the touch on the touch screen; and

adjusting a shooting angle of a camera lens according to the control signal.

14. The method of claim 13, wherein the shooting angle of the camera lens is adjusted by moving the camera lens a required distance along a direction corresponding to the displacement of the touching device on the touch screen, or moving the camera lens to a position corresponding to the touch point.

15. The method of claim 13, further comprising displaying images captured by the camera lens on the touch screen.
