If the user desires to define the center area of the signal sensing range 320 as the area for receiving the infrared signal 501, the remote controller 70 will generate an indicating signal 701, which indicates the center area as the area for receiving the infrared signal 501, by pressing the middle press key 72, and transmit the indicating signal 701 to the electronic device 10. The electronic device 10 receives the indicating signal 701 by the signal receiver 19, and transmits the indicating signal 701 to the self-photographing device 30 by the first signal transmission element 17. The self-photographing device 30 receives the indicating signal 701 by the second signal transmission element 35. Afterwards, the controller 33 of the self-photographing device 30 will define the first area 323 located within the center 321 of the signal sensing range 320 as the area for receiving the infrared signal 501, as shown in FIG. 4.

The electronic device 10 receives the indicating signal 702 by the signal receiver 19, and transmits the indicating signal 702 to the self-photographing device 30 by the first signal transmission element 17. The self-photographing device 30 receives the indicating signal 702 by the second signal transmission element 35. The controller 33 of the self-photographing device 30 controls the rotating of the motor 34 of the rotating platform 31 according to the offset value A2 indicated in the indicating signal 702, so that an area where the infrared receiver 32 desired to receive the infrared signal 501 is adjusted from the first area 323 to the second area 326, as shown in FIG. 12. In one embodiment of the present invention, besides, the infrared transmitter 50 and a remote controller 70 can be integrated into a single device.

In one embodiment of the present invention, similarly, the second area 326 is defined within the original signal sensing range 320 of the infrared receiver 32. In another embodiment of the present invention, the second area 326 is defined outside the original signal sensing range 320 of the infrared receiver 32.

In the present embodiment, the signal receiver 38 for receiving the signal transmitted from the remote controller 70 can be selectively configured within the self-photographing device 30. The signal receiver 38 is connected to the controller 33. The self-photographing device 30 receives the indicating signal 701/702 transmitted from the remote controller 70. Thus, the controller 33 of the self-photographing device 30 will define the first area 323 located within the center 321 of the signal sensing range 320 as the area for receiving the infrared signal 501 according to the indication of the indicating signal 701, as shown in FIG. 4. Otherwise, the controller 33 of the self-photographing device 30 controls the rotating of the motor 34 of the rotating platform 31 according to the offset value A2 indicated in the indicating signal 702, so that the area where the infrared receiver 32 desired to receive the infrared signal 501 is adjusted from the first area 323 to the second area 326, as shown in FIG. 12.

Accordingly, the self-photographing system 100 of the present invention defines or adjusts the area 323/325/326 where the infrared receiver 32 desired to receive the infrared signal 501 according to the objects (such as user's body parts and/or background contents) to be self-photographed or application scene, and therefore the lens 13 of the electronic device 10 can take photo or record video for objects to be self-photographed in a particular angle or position.

When the infrared receiver 32 receives the infrared signal 501, the controller 33 judges whether the wavelength and the frequency of the infrared signal 501 is equal to the specific wavelength and the specific frequency specified by the self-photographing system 100. If the wavelength and the frequency of the infrared signal 501 is equal to the specific wavelength and the specific frequency specified by the self-photographing system 100, the self-photographing system 100 will execute the rotating operation of the self-photographing device 30; or else, the rotating operation of the self-photographing device 30 will be inhibited. By the specification of the wavelength and the frequency of the infrared signal 501, it is possible to avoid an unpredictable infrared signal, for example, an infrared signal generated by fluorescent lamp, to interfere the operation of the self-photographing system 100.

The infrared transmitter 50 has a plurality of light emitting elements, for example, LED. Each of light emitting elements can emit an infrared signal 501. Thus, the infrared receiver 32 receives a plurality of infrared signals 501 (such as nine infrared signals 501) at different angles. The infrared receiver 32 will take the infrared signal with the largest spot and the brightest luminance as the target to be tracked and received.

In the step S93, the infrared receiver 32 determines whether a wavelength and a frequency of the infrared signal 501 is equal to a specific wavelength and a specific frequency specified by the self-photographing system 100. If the wavelength and the frequency of the infrared signal 501 is equal to the specific wavelength and the specific frequency specified by the self-photographing system 100, the self-photographing system 100 will execute the rotating operation of the self-photographing device 30; or else, the wavelength and the frequency of the infrared signal 501 is not equal to the specific wavelength and the specific frequency specified by the self-photographing system 100, the rotating operation of the self-photographing device 30 will be inhibited.
