In general, in order to realize self-timer shooting or remote shooting, a shooting device is generally provided with a function of remote control related to voice control or the like. However, the voice control scheme can only be used on water, but cannot be used in underwater scenes. In addition, if the remote controller is used for remotely controlling the shooting device, the remote control on the shooting device is realized by emitting infrared signals through the remote controller in the related art. However, also when the photographing apparatus is in an underwater scene, the manner of infrared control often fails, resulting in that the photographing apparatus cannot be controlled normally by the remote controller.

In view of this, the present embodiment provides a photographing apparatus and a remote control device, wherein the photographing apparatus includes an ultrasonic receiving circuit, a control circuit, and a photographing assembly. The ultrasonic receiving circuit can receive the target ultrasonic signal, the control circuit is connected with the ultrasonic receiving circuit, and the control circuit outputs a control signal corresponding to the target ultrasonic signal under the condition that the ultrasonic receiving circuit receives the target ultrasonic signal; the shooting component is connected with the control circuit, receives the control signal and executes corresponding shooting actions according to the control signal. Therefore, the shooting equipment can accurately execute corresponding shooting actions by receiving the target ultrasonic signals sent by the remote control device, and the problem of failure in controlling the underwater application scene is effectively avoided.

Referring to fig. 1, a schematic structural diagram of a photographing apparatus according to an embodiment of the present application is shown. The photographing apparatus 100 includes an ultrasonic receiving circuit 101, a control circuit 102, and a photographing assembly 103. The ultrasonic receiving circuit 101 is configured to receive a target ultrasonic signal; the control circuit 102 is connected with the ultrasonic receiving circuit, and when the ultrasonic receiving circuit receives the target ultrasonic signal, the control circuit 102 outputs a control signal corresponding to the target ultrasonic signal; the shooting component 103 is connected with the control circuit 102, and the shooting component 103 receives the control signal and executes corresponding shooting actions according to the control signal.

Wherein the ultrasonic receiving circuit 101 can receive the target ultrasonic signal output by the remote control device. Optionally, the remote control device is a remote control device matched with the photographing apparatus 100.

After receiving the target ultrasonic signal, the ultrasonic receiving circuit 101 transmits the target ultrasonic signal to the control circuit 102. Alternatively, the control circuit 102 may determine an ultrasonic frequency corresponding to the target ultrasonic signal, then determine a photographing function corresponding to the ultrasonic frequency, further generate a control signal corresponding to the photographing function, and send the generated control signal to the photographing component 103.

Alternatively, the control circuit 102 may generate the corresponding control signal by querying a function definition table from the function definition table, where the function definition table includes a plurality of sets of correspondence between ultrasonic frequencies and photographing functions. The process of searching the shooting function corresponding to the ultrasonic frequency and generating the corresponding control signal from the function definition table is only required to be implemented by a conventional control mode, and is not repeated.

The ultrasonic frequency of the target ultrasonic signal is more than 20 KHz. Alternatively, the target ultrasound signal may be a composite ultrasound signal, i.e., the target ultrasound signal may comprise ultrasound signals of a plurality of different ultrasound frequencies. The combination of the ultrasonic frequencies of each ultrasonic signal in the target ultrasonic signal may correspond to the control signal, that is, the target ultrasonic signals combined by different ultrasonic frequencies have different corresponding shooting functions and further different corresponding control signals, so that the shooting component 103 may execute different shooting actions according to different control signals.

Alternatively, the ultrasonic receiving circuit 101 may pick up a normal audio signal and transmit the normal audio signal to the control circuit 102. Wherein the general audio signal may refer to an audio signal that is perceivable by the human ear.

In the photographing apparatus 100, the photographing apparatus 100 includes an ultrasonic receiving circuit 101, a control circuit 102, and a photographing component 103, where the ultrasonic receiving circuit 101 may receive a target ultrasonic signal, the control circuit 102 is connected to the ultrasonic receiving circuit, and the control circuit 102 outputs a control signal corresponding to the target ultrasonic signal when the ultrasonic receiving circuit receives the target ultrasonic signal; the shooting component 103 is connected with the control circuit 102, and the shooting component 103 receives the control signal and executes corresponding shooting actions according to the control signal. Because the shooting device 100 can execute the corresponding shooting action by receiving the target ultrasonic signal, the ultrasonic signal is easy to propagate underwater, and the distance of the ultrasonic signal propagating underwater is quite long, when the shooting device 100 is in an underwater application scene, the corresponding shooting action can be accurately executed by receiving the target ultrasonic signal sent by the remote control device, and the problem of failure of remote control in the underwater application scene is effectively avoided.

In one embodiment, as shown in fig. 2, a schematic structural diagram of a photographing apparatus provided in an embodiment of the present application is shown. The photographing assembly 103 in the photographing apparatus 100 includes at least two image sensors 103a, and the at least two image sensors 103a perform corresponding photographing actions according to the control signal, wherein the photographing actions include single-lens photographing, multi-lens photographing, and single-lens switching photographing. It should be noted that fig. 2 only includes two image sensors 103a as an example, and is not intended to limit the present application.

Wherein the image sensor 103a in the photographing assembly 103 may perform different photographing actions according to the received control signals. For example, when the frequency of the target ultrasonic signal is the first ultrasonic frequency, corresponding to the first control signal, one image sensor 103a in the shooting assembly 103 works according to the first control signal to realize single-lens shooting; when the frequency of the target ultrasonic signal is the second ultrasonic frequency, corresponding to the second control signal, two image sensors 103a in the shooting assembly 103 work simultaneously according to the second control signal so as to realize multi-lens shooting; when the frequency of the target ultrasonic signal is the third ultrasonic frequency, the two image sensors 103a in the shooting assembly 103 are switched to work according to the third control signal corresponding to the third control signal, so that single-lens switching shooting is realized.

Alternatively, as noted above, the target ultrasonic signal may be a composite ultrasonic signal, and thus the target ultrasonic signal may be composed of a combination of ultrasonic signals of a plurality of different ultrasonic frequencies, that is, the first ultrasonic frequency, the second ultrasonic frequency, and the third ultrasonic frequency may be composed of a plurality of different ultrasonic frequencies.

It will be appreciated that in addition to performing the above-described photographing actions, the photographing component 103 may perform other photographing actions according to the difference of the ultrasonic frequencies corresponding to the control signals. Illustratively, when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 24KHz, the photographing action performed by the photographing component 103 is to start video recording; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 25KHz, the shooting action performed by the shooting component 103 is to finish video recording; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 26KHz, the shooting action performed by the shooting component 103 is to start shooting; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 27KHz, the shooting action performed by the shooting component 103 is to finish shooting; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz, and 28KHz, the photographing action performed by the photographing component 103 is to start HDR (High Dynamic Range Imaging ) photographing; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 29KHz, the shooting action performed by the shooting component 103 is to end HDR shooting; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 30KHz, the shooting action performed by the shooting component 103 is to start HDR video recording; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 31KHz, the shooting action performed by the shooting component 103 is ending the HDR video recording; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 32KHz, the shooting action performed by the shooting component 103 is to start slow-action video recording; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 33KHz, the shooting action executed by the shooting component 103 is to finish the slow action video recording; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 34KHz, the shooting action performed by the shooting component 103 is to start starry sky mode shooting; when the ultrasonic frequency of the target ultrasonic signal is a combination of 20KHz, 22KHz and 35KHz, the photographing action performed by the photographing component 103 is to end the starry sky mode photographing. Note that, in addition to the above-described exemplary photographing actions, the photographing apparatus 100 may perform other photographing actions according to different control signals, which are not entirely illustrated herein.

In one embodiment, as shown in fig. 3, a schematic structural diagram of a photographing apparatus provided in an embodiment of the present application is shown. Wherein the ultrasound receiving circuit 101 in the photographing apparatus 100 includes a filter 101a, the filter 101a being connected to the control circuit 102.

After the ultrasonic receiving circuit 101 receives the target ultrasonic signal, the target ultrasonic signal may be transmitted to the filter 101a, so that the filter 101a may perform filtering processing on the target ultrasonic signal. Noise components in the target ultrasonic signal are suppressed through the filtering process to achieve correction of the frequency of the target ultrasonic signal, thereby enabling the control circuit 102 to receive a more stable target ultrasonic signal and ensuring the accuracy of the implementation of the photographing apparatus 100 by the remote control function.

In one embodiment, as shown in fig. 4, a schematic structural diagram of a photographing apparatus provided in an embodiment of the present application is shown. The ultrasound receiving circuit 101 in the photographing apparatus 100 further includes a demodulator 101b, and the demodulator 101b is connected to the filter 101 a.

The demodulator 101b is connected to the filter 101a, so that the ultrasonic receiving circuit 101 receives the target ultrasonic signal, then inputs the target ultrasonic signal to the demodulator 101b, demodulates the target ultrasonic signal by the demodulator 101b, generates a signal recognizable by the control circuit 102, and inputs the demodulated signal to the filter 101a, and outputs the signal to the control circuit 102 after the filtering process. Based on this, since demodulation is performed by the demodulator 101b, the control circuit 102 can quickly determine the ultrasonic frequency of the target ultrasonic signal, and thus output a control signal corresponding thereto.

In one embodiment, as shown in fig. 5, a schematic structural diagram of a photographing apparatus provided in an embodiment of the present application is shown. The ultrasound receiving circuit 101 in the photographing apparatus 100 further includes an ultrasound microphone 101c, and the ultrasound microphone 101c is connected to the demodulator 101 b.

The ultrasonic microphone 101c is a microphone device that can receive signals having a frequency of 20KHz or more.

The ultrasonic receiving circuit 101 may receive the target ultrasonic signal through the ultrasonic microphone 101c, and further transmit the target ultrasonic signal to the demodulator 101b for demodulation. The demodulated signal is transmitted to the filter 101a for further filtering processing, and thus to the control circuit 102.

Alternatively, the ultrasonic receiving circuit 101 may pick up a normal audio signal by the ultrasonic microphone 101c and transmit the normal audio signal to the control circuit 102. Alternatively, the ultrasonic receiving circuit 101 may pick up the normal audio signal by the ultrasonic microphone 101c, perform filtering processing on the normal audio signal by using the filter 101a, and transmit the filtered normal audio signal to the control circuit 102.

In this embodiment of the present application, by receiving the target ultrasonic signal sent by the remote control device, remote control of the shooting device 100 under water may be achieved, and by using diversity of combinations of ultrasonic frequencies of the ultrasonic signals, infinite control combinations may be achieved, and ultrasonic signals corresponding to different control functions may be freely defined, where the signal has uniqueness, and the more complex the ultrasonic frequency combination of the ultrasonic signals, the stronger its anti-interference performance, so that occurrence of erroneous recognition and interference situations may be effectively avoided, and stability and reliability of remote control are ensured.

In one embodiment, as shown in fig. 6, an electrical schematic diagram of an ultrasound receiving circuit provided in an embodiment of the present application is shown. Wherein DMIC_VDD is a power supply terminal; mic_clk is the clock signal; mic_dat is the received ultrasound signal; VDD, L/R, CLK, DATA, etc. are control pins of the ultrasound receiving circuit.

In one embodiment, as shown in fig. 7, a schematic structural diagram of a photographing apparatus provided in an embodiment of the present application is shown. The photographing apparatus 100 further includes an indication lamp 104, and the indication lamp 104 is connected to the control circuit 102 for indicating a connection state of the photographing apparatus 100.

When the control circuit 102 outputs a control signal corresponding to the target ultrasonic signal to the shooting component 103, during the shooting component 103 performs the corresponding shooting action, the indicator light 104 displays a corresponding indication state according to the control of the control circuit 102, so that a user can determine whether the current shooting device 100 is connected with the remote control device, so as to perform the corresponding shooting action under the control of the remote control device. It is understood that the indication state of the indication lamp 104 is different in a state in which the photographing apparatus 100 is controlled by the remote control device through the target ultrasonic signal and a state in which the photographing apparatus 100 is not controlled by the remote control device through the target ultrasonic signal, for example, the indication lamp 104 is not lighted in an uncontrolled state, and the indication lamp 104 blinks in a controlled state.

Optionally, when the photographing apparatus 100 performs each photographing action, the indicator light 104 may also display an indication state corresponding to the photographing action, so that the user can determine the current photographing action.

Based on the same technical concept, the embodiment of the application also provides a remote control device corresponding to the shooting device, which is used for outputting the target ultrasonic signal, and the remote control device is described below.

In one embodiment, as shown in fig. 8, a schematic structural diagram of a remote control device provided in an embodiment of the present application is shown. The remote control device 200 includes a remote control assembly 201, a drive circuit 202, and an ultrasound transmission circuit 203. The remote control component 201 is configured to generate a trigger signal; the driving circuit 202 is connected with the remote control assembly 201, and outputs a corresponding target driving signal based on the trigger signal; the ultrasound transmitting circuit 203 is connected to the driving circuit 202, receives and generates and transmits the target ultrasound signal received by the ultrasound receiving circuit 101 in the photographing apparatus 100 in the above embodiments, based on the target driving signal.

The remote control component 201 is a component that can be triggered by a user, and when the remote control component 201 is triggered by the user, the remote control component 201 generates a corresponding trigger signal according to a trigger action performed by the user. The driving circuit 202 is connected to the remote control unit 201, and when a trigger signal is detected, the driving circuit 202 generates a target driving signal corresponding to the trigger signal and transmits the target driving signal to the ultrasonic transmitting circuit 203. The ultrasound transmit circuit 203 may generate a target ultrasound signal corresponding to the target drive signal and transmit the target ultrasound signal.

Wherein, the effective bandwidth of the ultrasonic transmitting circuit 203 is above 20KHz, and the target ultrasonic signal transmitted by the ultrasonic transmitting circuit is not perceived by human ears.

Alternatively, when the remote control assembly 201 detects a trigger action by the user, the corresponding drive circuit 202 drives the ultrasound transmit circuit 203 to generate a target ultrasound signal comprising a single ultrasound frequency based on the target drive signal.

Alternatively, when the remote control detection component detects a trigger action by the user, the corresponding driving circuit 202 drives the ultrasonic transmission circuit 203 to generate a target ultrasonic signal including a plurality of different ultrasonic frequencies based on the target driving signal. Alternatively, when the remote control detection component detects a plurality of trigger actions of the user, the driving circuit 202 generates a corresponding target driving signal based on the plurality of trigger actions, and drives the ultrasonic transmission circuit 203 to generate a target ultrasonic signal including a plurality of different ultrasonic frequencies based on the target driving signal.

It may be appreciated that, according to different trigger actions of the user detected by the remote control assembly 201, the remote control assembly 201 may generate trigger signals corresponding to the trigger actions respectively, and further generate a target driving signal corresponding to the trigger action based on the trigger signals, so as to generate a target ultrasonic signal corresponding to the trigger action based on the target driving signal. In this way, when the user needs to control the shooting device matched with the remote control device 200 to perform the required shooting action through the remote control device 200, the user performs the target triggering action on the remote control component 201 of the remote control device 200, so that the remote control device 200 transmits the corresponding target ultrasonic signal through the ultrasonic transmitting circuit 203, and after the shooting device 100 receives the target ultrasonic signal through the ultrasonic receiving circuit 101, the shooting component 103 can be further controlled to perform the required shooting action, so as to realize the remote control of the shooting device 100 through the remote control device 200.

In the remote control device 200, since the remote control device 200 can generate the corresponding trigger signal based on the trigger action of the user, and further drive the ultrasonic transmitting circuit 203 to transmit the corresponding target ultrasonic signal, the photographing apparatus 100 can perform the corresponding photographing action by receiving the target ultrasonic signal. Because the ultrasonic signal is easy to propagate underwater and the distance of propagation is quite long, when the shooting equipment 100 is in an underwater application scene, the shooting equipment can still normally receive the target ultrasonic signal sent by the remote control device 200 and accurately execute the corresponding shooting action, thereby effectively avoiding the occurrence of the problem of failure of remote control in the underwater application scene.

In one embodiment, as shown in fig. 9, a schematic structural diagram of a remote control device provided in an embodiment of the present application is shown. The remote control assembly 201 includes a combination of one or more of mechanical keys 201a, knobs 201b, and switches 201 c.

When the user activates one of the mechanical keys 201a, the knob 201b, the switch 201c, and the like, the remote control assembly 201 generates a trigger signal corresponding to the target key according to the activated target key, to further cause the ultrasonic transmission circuit 203 to generate a target ultrasonic signal corresponding to the target key.

Alternatively, the triggering action for the switch 201c or the mechanical key 201a may be pressing the mechanical key 201a, and the triggering action for the knob 201b may be rotating the knob 201b clockwise or counterclockwise.

Illustratively, when the user triggers the mechanical key 1 in the remote control assembly 201, the ultrasound transmit circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 24 KHz; when the user triggers the mechanical key 2 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 25 KHz; when the user triggers the mechanical key 3 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 26 KHz; when the user triggers the mechanical key 4 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 27 KHz; when the user triggers the mechanical key 5 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 28 KHz; when the user triggers the mechanical key 6 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 29 KHz; when the user triggers the mechanical key 7 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 30 KHz; when the user triggers the mechanical key 8 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 31 KHz; when the user triggers the mechanical key 9 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 32 KHz; when the user triggers the mechanical key 10 in the remote control assembly 201, the ultrasound transmitting circuit 203 generates and transmits a target ultrasound signal having a combination of ultrasound frequencies of 20KHz, 22KHz and 33 KHz; when the user triggers the mechanical key 1 and the mechanical key 2 in the remote control assembly 201, the ultrasonic transmitting circuit 203 generates and transmits a target ultrasonic signal with ultrasonic frequencies of a combination of 20KHz, 22KHz and 34 KHz; when the user activates the mechanical key 1 and the mechanical key 3 in the remote control assembly 201, the ultrasonic transmission circuit 203 generates and transmits a target ultrasonic signal having a combination of ultrasonic frequencies of 20KHz, 22KHz and 35 KHz. It will be appreciated that different keys and combinations of different keys may generate target ultrasonic signals of different ultrasonic frequency combinations when triggered; the number of combinations is many, and the more complex the combination, the lower the probability that the target ultrasound signal is misrecognized, the better the immunity to interference, which is not fully exemplified herein.

Optionally, the modulator 203a may modulate the received target driving signal to modulate the target driving signal into a signal that can be identified by the ultrasonic transmitting circuit 203, so that the ultrasonic transmitting circuit 203 generates a corresponding target ultrasonic signal and directly plays the target ultrasonic signal.

Optionally, after receiving the target driving signal transmitted by the driving circuit 202, the modulator 203a modulates the signal initially generated by the ultrasonic transmitting circuit 203 to obtain a target ultrasonic signal that can be directly identified by the sound generating element in the ultrasonic transmitting circuit 203, so that the sound generating element can directly transmit the target ultrasonic signal.

The ultrasonic speaker 203b is connected to the modulator 203a such that the ultrasonic speaker 203b directly emits the target drive signal obtained by modulation by the modulator 203 a.
