[0046] Figure 4 A schematic diagram schematically illustrates the C-plane of the remote control device according to an embodiment of the present disclosure.

[0047] like Figure 4 As shown, a mode switching button 141 may be provided on the C surface of the shell for switching between the voice remote control mode and the recording mode.

[0048] Figure 5 A schematic diagram schematically illustrates the D surface of the remote control device according to an embodiment of the present disclosure.

[0052] Figure 6 A schematic diagram of the system architecture of a remote control device according to an embodiment of the present disclosure is schematically shown.

[0053] exist Figure 6 In the illustrated embodiment, the remote control device 200 may include a microphone 210, a button 220, a main controller 260, and an antenna 280 to implement the functions described above. The button 220 may include the photo control button 132, the video control button 133, the mode switching button 141, the first adjustment button 151, and the second adjustment button 152, etc., as described above. The main controller 260 may be implemented as a microcontroller (MCU, Microcontroller Unit), some of which have an on-chip read-only memory (ROM). If the microcontroller does not have an on-chip read-only memory, the main controller 260 may be implemented as a combination of a microcontroller and a read-only memory.

[0054] like Figure 6 As shown, the remote control device 200 may further include an audio processing unit 230, a key processing unit 240 and an instruction storage unit 250. The audio processing unit 230 is respectively connected to the microphone 210, the instruction storage unit 250 and the main controller 260. The key processing unit 240 is respectively connected to the key 220, the instruction storage unit 250 and the main controller 260.

[0055] In this embodiment, the main controller 260 may not directly process the signals from the microphone 210 and the button 220, but the audio processing unit 230 and the button processing unit 240 may process these signals respectively, generate primary control instructions, and transmit the primary control instructions to the main controller 260, and the main controller 260 may generate the final secondary control instructions and send them to the controlled camera device through the antenna. Figure 1-Figure 5 The button control instructions and voice control instructions described are all secondary control instructions.

[0056] According to an embodiment of the present disclosure, the instruction storage unit 250 can be used to store the mapping relationship between the sound signal and the primary control instruction, and the mapping relationship between the key signal and the primary control instruction. For example, the instruction storage unit can store a voice wake-up instruction, that is, an instruction to generate a device wake-up when a specific wake-up word is received. The instruction storage unit 250 can be implemented as an electrically erasable programmable read only memory (EEPROM, Electrically ErasableProgrammable read only memory), for example. The audio processing unit 230 is used to identify the sound signal collected by the microphone 210 as a primary control instruction according to the mapping relationship; the key processing unit 240 is used to identify the key input as a primary control instruction according to the mapping relationship.

[0057] Figure 7 A schematic diagram of the system architecture of a remote control device according to another embodiment of the present disclosure is schematically shown.

[0058] like Figure 7 As shown, the audio processing unit 230 and the key processing unit 240 may also not be pressed. Figure 6 The manner shown is respectively connected to the main controller 260, but the audio processing unit 230 may be connected to the key processing unit 240, and the key processing unit 240 may be connected to the main controller 260. In this way, various signals or instructions generated by the audio processing unit 230 can be uniformly sent to the main controller 260 through the key processing unit 240. For example, the audio processing unit 230 receives information from the microphone 210, identifies whether the audio is a wake-up audio instruction stored in the instruction storage unit 250, and if so, transmits it to the key processing unit 240, and uniformly sends it to the main controller 260 through the key processing unit 240.

[0059] According to an embodiment of the present disclosure, the remote control device 200 may further include a wireless transceiver unit 270, which is connected to the main controller 260 and the antenna 280, respectively. For example, the wireless transceiver unit 270 may be implemented as a 2.4G wireless module. The secondary control instructions generated by the main controller 260 according to the primary control instructions may be transmitted to the antenna 280 through the wireless transceiver unit 270 for transmission, thereby decoupling the communication-related functions from the main controller 260 and reducing the complexity of the main controller 260.

[0060] although Figure 6 and Figure 7 The various indicator lights on the housing are not shown, but those skilled in the art will appreciate that the main controller may be directly or indirectly connected to these indicator lights so as to control these indicator lights to illuminate at appropriate times to prompt the user.

[0061] According to the embodiment of the present disclosure, Figure 6 and Figure 7 The various units shown can be integrated on one or more printed circuit boards. For example, the audio processing unit 230 can be designed as a module, the main controller 260, the instruction storage unit 250, the key processing unit 240 and the wireless transceiver unit 270 can be designed as a module, and the antenna 280 can be designed as a module. The above three modules can be integrated on the same printed circuit board.

[0062] According to an embodiment of the present disclosure, a power module, such as a lithium-ion rechargeable battery, may also be provided in the remote control device 200, which may be connected to the audio processing unit 230, the key processing unit 240, the main controller 260, and the wireless transceiver unit 270, and supply energy thereto.

[0063] The above description is only a preferred embodiment of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of protection involved in the present disclosure is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above technical concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present disclosure (but not limited to) by each other.
