In this embodiment, a signal received by the first communication interface is obtained, where the first communication interface is connected to the second communication interface through a data line, and the signal received by the first communication interface depends on a signal sent by the shooting device through the second communication interface, and therefore, the signal received by the first communication interface can reflect a device state of the shooting device.

In this embodiment, when the shooting device is electrically disconnected from the wireless image transmission device or the shooting device is in the power-off state, the wireless image transmission device does not need to transmit images, and continuously keeping the wireless image transmission device in the power-on state will cause electric energy waste and also cause loss to the service life of the wireless image transmission device. The power-on state of the wireless image transmission device means that all circuit modules in the wireless image transmission device are in a power-on state.

The first part of circuit modules may be circuit modules set by the wireless image transmission device when the wireless image transmission device leaves a factory, or may be circuit modules designated by a user.

In this embodiment, if it is determined that the shooting device is in the power-on state and the shooting device is electrically connected to the wireless image transmission device, the power-on state of the wireless image transmission device is kept unchanged.

The third communication interface and the fourth communication interface may also be HDMI interfaces. Among them, the HDMI interface is capable of transmitting high-quality digital video signals and audio signals.

Optionally, the wireless image transmission device further comprises a power supply device. And if the shooting equipment is determined to be electrically disconnected from the wireless image transmission device or the shooting equipment is in a shutdown state, controlling the power supply device to stop supplying power to the wireless image transmission device or controlling the power supply device to stop supplying power to the first part of circuit modules of the wireless image transmission device. Therefore, the electric energy waste of the power supply device in the wireless image power supply device is avoided in time, and the endurance time of the wireless image power supply device is prolonged.

Optionally, when the wireless image transmission device further includes a third communication interface, the third communication interface is connected to the fourth communication interface of the cradle head through a data line, the power supply device may be further located in the cradle head, and the power supply device may establish a power supply connection with the wireless image transmission device through the fourth communication interface on the cradle head and the third communication interface on the wireless image transmission device, and supply power to the wireless image transmission device; or, the cradle head and the wireless image transmission device can be respectively provided with corresponding power supply interfaces, and the power supply device can establish power supply connection with the wireless image transmission device through the power supply interface on the cradle head and the power supply interface on the wireless image transmission device to supply power to the wireless image transmission device. If the shooting equipment is determined to be electrically disconnected from the wireless image transmission device or the shooting equipment is in a power-off state, the power supply connection between the power supply device and the wireless image transmission device can be disconnected to control the wireless image transmission device to be powered off, or the circuit of a first part of circuit modules in the wireless image transmission device can be controlled to be disconnected to stop the power supply device from supplying power to the first part of circuit modules.

Optionally, the first circuit module includes an image data wireless transmission circuit module, and the image data wireless transmission circuit module is configured to transmit image data to the terminal device in a wireless manner, so that power consumption is relatively high. When the shooting equipment is electrically connected with the wireless image transmission device or the shooting equipment is in a power-off state, the wireless transmission of the image data is naturally not needed, and the current use of the wireless image transmission device is not influenced and the power consumption of the wireless image transmission device can be effectively reduced by closing the wireless image data transmission circuit module.

Further, the first part of circuit modules may further include at least one of an image data format conversion circuit module and an encoding and decoding processing circuit module to further reduce power consumption of the wireless image transmission device. The image data format conversion circuit module is used for converting the data format of the image data into the data format supported by the wireless image transmission device, and the encoding and decoding processing circuit module is used for encoding and decoding the image data.

In the control method of the wireless image transmission apparatus provided in this embodiment, when the wireless image transmission apparatus is in the power-on state, if it is determined that the shooting device is electrically disconnected from the wireless image transmission apparatus or the shooting device is in the power-off state according to the signal received by the first communication interface, the wireless image transmission apparatus is controlled to be powered off or power supply to the first part of the circuit modules of the wireless image transmission apparatus is stopped, so that when it is determined that the shooting device is electrically disconnected from the wireless image transmission apparatus or the shooting device is in the power-off state, waste of electric energy of the wireless image transmission apparatus is avoided or reduced as much as possible in time, and the endurance time and the service life of the wireless image transmission apparatus are improved. The user does not need to worry about that the wireless image transmission device is always kept in the starting state after forgetting to manually turn off the wireless image transmission device, and the intelligence and the user experience of the wireless image transmission device are effectively improved.

In some embodiments, the first communication interface includes a power signal pin, and the signal received by the first communication interface includes a signal received by the power signal pin of the first communication interface, so that whether the shooting device is electrically disconnected from the wireless image transmission apparatus or whether the shooting device is in a power-off state can be determined more accurately and more efficiently according to the signal received by the power signal pin of the first communication interface.

One possible implementation manner of the foregoing S302 is: when the wireless image transmission device is in a power-on state, whether a signal received by a power signal pin of the first communication interface is a power signal output by the shooting equipment through the second communication interface is determined, and if not, the shooting equipment is determined to be electrically disconnected from the wireless image transmission device or the shooting equipment is in a power-off state.

In this embodiment, the power signal pin of the second communication interface is connected to the power signal pin of the first communication interface, and when the shooting device is in the power-on state and the shooting device is electrically connected to the wireless image transmission device, the power signal pin of the second communication interface outputs a corresponding signal to the power signal pin of the first communication interface. Therefore, if the signal received by the power signal pin of the first communication interface is not the power signal output by the shooting device through the second communication interface, it is determined that the shooting device is electrically disconnected from the wireless image transmission device or the shooting device is in a power-off state.

Optionally, it may be determined whether the power signal pin of the first communication interface receives the power signal output by the second communication interface within a preset time period, and if not, it may be determined that the shooting device is electrically disconnected from the wireless image transmission device or the shooting device is in a power-off state, so that by determining a signal received by the power signal pin of the first communication interface within a certain preset time period, accuracy of determining that the shooting device is electrically disconnected from the wireless image transmission device or the shooting device is in the power-off state is improved, and accuracy and effect of controlling the wireless image transmission device are improved.

Optionally, it is determined whether a signal received by the power signal pin of the first communication interface is a power signal of a preset voltage threshold (or a current threshold), and if so, it is determined that the signal received by the power signal pin of the first communication interface is a power signal output by the shooting device through the second communication interface, otherwise, the signal received by the power signal pin of the first communication interface is not a power signal output by the shooting device through the second communication interface, so as to improve accuracy of signal determination of the power signal pin of the first communication interface.

For example, taking the first communication interface and the second communication interface as HDMI interfaces as an example, when the camera device is electrically connected to the wireless image transmission device and the camera device is in the power-on state, the power signal pin of the first communication interface may generally receive the power signal with the voltage value of 5 volts output by the second communication interface, and if the power signal pin of the first communication interface does not receive the power signal with the voltage value of 5 volts, it is determined that the camera device is electrically disconnected from the wireless image transmission device or the camera device is in the power-off state.

Further, after determining whether the signal received by the power supply signal pin of the first communication interface is the power supply signal output by the shooting device through the second communication interface according to whether the signal received by the power supply signal pin of the first communication interface is the power supply signal output by the shooting device through the second communication interface, one possible implementation manner of S303 is: and if the shooting equipment is electrically disconnected from the wireless image transmission device or the shooting equipment is in a power-off state, controlling the wireless image transmission device to be powered off.

In this embodiment, when the signal received by the power signal pin of the first communication interface is not the power signal output by the shooting device through the second communication interface, the shooting device is powered off or disconnected from the wireless image transmission device, and the wireless image transmission device does not receive the image data output by the shooting device any more, so that the wireless image transmission device can be directly controlled to be powered off, thereby avoiding electric energy waste.

In some embodiments, the first communication interface includes an image data receiving pin, and the signal received by the first communication interface includes a signal received by the image data receiving pin of the first communication interface, wherein the signal received by the image data receiving pin includes image data. Therefore, whether the shooting equipment is electrically disconnected with the wireless image transmission device or whether the shooting equipment is in a power-off state can be determined more accurately and more efficiently according to the signals received by the image data receiving pin of the first communication interface.

One possible implementation manner of the foregoing S302 is: when the wireless image transmission device is in a power-on state, whether a signal received by the image data receiving pin of the first communication interface comprises image data output by the shooting equipment through the second communication interface is determined, and if not, the shooting equipment is determined to be electrically disconnected from the wireless image transmission device or the shooting equipment is in a power-off state.

In this embodiment, when the shooting device is in the power-on state and the shooting device is electrically connected to the wireless image transmission device, the shooting device outputs a corresponding signal to the image data receiving pin of the first communication interface through the second communication interface. Therefore, if the signal received by the image data receiving pin of the first communication interface does not include the image data output by the shooting device through the second communication interface, it can be determined that the shooting device is electrically disconnected from the wireless image transmission device or the shooting device is in a power-off state. And if the shooting equipment is electrically disconnected from the wireless image transmission device or the shooting equipment is in a power-off state, controlling the wireless image transmission device to be powered off or stopping power supply to the first part of circuit modules of the wireless image transmission device.

For example, taking the first communication interface and the second communication interface as HDMI interfaces as an example, when the shooting device is electrically connected to the wireless image transmission apparatus and the shooting device is in the power-on state, the image data receiving pin of the first communication interface can receive the HDMI signal output by the second communication interface, where the HDMI signal includes image data. And if the power signal pin of the first communication interface does not receive the HDMI signal output by the second communication interface, determining that the shooting equipment is electrically disconnected with the wireless image transmission device or the shooting equipment is in a power-off state.

Optionally, it may be determined whether a signal received by the image data receiving pin of the first communication interface within a preset time period includes image data output by the shooting device through the second communication interface, and if not, it may be determined that the shooting device is electrically disconnected from the wireless image transmission device or the shooting device is in a power-off state, so that by determining that the signal received by the image data receiving pin of the first communication interface within a certain preset time period is received, influences of factors such as signal delay and a time interval for the shooting device to acquire the image data are fully considered, accuracy of determining that the shooting device is electrically disconnected from the wireless image transmission device or the shooting device is in the power-off state is improved, and accuracy and effect of controlling the wireless image transmission device are further improved.

In some embodiments, the first communication interface includes a power signal pin and an image data receiving pin, and the signal received by the first communication interface includes a signal received by the power signal pin of the first communication interface and a signal received by the image data receiving pin of the first communication interface. When the wireless image transmission device is in a power-on state, if the signal received by the image data receiving pin of the first communication interface does not include the image data output by the shooting equipment through the second communication interface and the signal received by the power signal pin of the first communication interface is the power signal output by the shooting equipment through the second communication interface, the power supply to the first part of circuit modules of the wireless image transmission device is stopped, so that the accuracy and the effect of controlling the power supply of the wireless image transmission device can be improved according to the signal received by the power signal pin of the first communication interface and the signal received by the image data receiving pin of the first communication pin.

In this embodiment, if the signal received by the image data receiving pin of the first communication interface does not include the image data output by the shooting device through the second communication interface and the signal received by the power signal pin of the first communication interface is the power signal output by the shooting device through the second communication interface, it can be considered that the shooting device is in the power-on state and the shooting device is electrically connected to the wireless image transmission device, but the shooting device does not output the image data to the wireless image transmission device through the second communication interface. The reason for this may be that the shooting device in the power-on state does not perform image data acquisition, the second communication interface fails, and the like. At this time, the wireless image transmission device may subsequently receive the image data output by the shooting device, so that the power supply to the first part of circuit module may be stopped, thereby reducing the power waste of the wireless image transmission device, and avoiding the inconvenience of image transmission and the influence on the user experience caused by controlling the wireless image transmission device to be powered off.

In some embodiments, in the process of sending the image data output by the shooting device through the second communication interface to the cradle head by the wireless image transmission device, the wireless image transmission device receives the image data output by the shooting device through the second communication interface according to the first data protocol through the first communication interface, converts the received image data conforming to the first data protocol into image data conforming to the second data protocol, and outputs the image data conforming to the second data protocol to the cradle head through the third communication interface. The number of signal lines of the data lines required for transmitting the image data of the first data protocol is larger than that of the signal lines of the data lines required for transmitting the image data of the second data protocol. Therefore, the wireless image transmission device reduces the number of signal lines of the data lines in the wireless image transmission device and the cradle head by converting the image data from the first data protocol to the second data protocol, and avoids the situation that the structure of the cradle head is more limited due to the fact that the number of the signal lines of the data lines is large. For example, the greater number of signal lines of the data lines makes the rotation resistance between the respective shaft arms greater, which affects the flexibility of the rotation of the respective shaft arms of the pan/tilt head.

For example, in the handheld cloud deck 103 shown in fig. 2, the data line 201 needs to pass through the hollow first shaft arm 1033, the second shaft arm 1034 and the third shaft arm 1035, and at the connection position of the second shaft arm 1034 and the third shaft arm 1035, the data line 201 passes through a hole in the middle of the electrical tilt board 202 to be connected with the electrical tilt board 202. When the number of the signal lines of the data line 201 is large, firstly, the weight of the handheld cloud deck 103 is increased, secondly, a large space needs to be reserved inside each shaft arm, so that the data line can pass through, thus each shaft arm is thick, the size of the handheld cloud deck 103 is influenced, the portability of the handheld cloud deck 103 is further influenced, thirdly, the difficulty of rotation of each shaft arm is increased, the number of the signal lines of the data line 201 is large, and the resistance of rotation of each shaft arm is large. Therefore, the number of signal lines of the data lines is reduced, which is beneficial to improving the portability and portability of the handheld cloud deck 103 and the flexibility of rotation of each shaft arm, and improving the control performance of the handheld cloud deck 103.

Optionally, the first data protocol includes an HDMI protocol, and the second data protocol includes a Composite Video Broadcast Signal (CVBS) protocol. The HDMI interface suitable for the HDMI protocol generally has 19 pins, including a plurality of image data receiving pins, power signal pins, ground pins, clock pins, and the like, and the number of signal lines of the adopted data lines is large. The data line of the CVBS protocol is generally a single shielded coaxial cable, and includes only coaxial signal lines and shielded lines, and the number of signal lines is small.

Optionally, the second data protocol may be any one of an SDI interface protocol and a super-Video (Duper-Video) protocol having a smaller number of signal lines of data lines.

Wherein, the microprocessor management module is a microprocessor.
