At present, a shooting terminal generally has a plurality of mutually exclusive functions, and after a certain function is set, other functions mutually exclusive to the function are invalid, because the user interface of the control terminal is independent of the user interface of the shooting terminal and the control terminal does not execute logic processing, when the shooting terminal disables the mutually exclusive functions and displays that the mutually exclusive functions are not available on the user interface of the shooting terminal, the mutually exclusive functions are still available on the display interface of the control terminal, and the display of the shooting terminal and the display interface of the control terminal are not synchronous, so that the user experience is poor.

According to the mode control information of the shooting terminal, the disabling function in the corresponding mode indicated by the mode control information is determined, and the shooting terminal and the control terminal adjust interaction controls corresponding to the disabling function into a disabling state in respective user interfaces according to the determined disabling function, so that the user interfaces of the shooting terminal and the control terminal are kept consistent, and user experience is improved.
Embodiments of the present application are further described below with reference to the accompanying drawings of embodiments of the present application.
Example 1
An embodiment of the present application provides a method for synchronizing states of interactive controls, and fig. 1 is a schematic flowchart of a method for synchronizing states of interactive controls provided in an embodiment of the present application. As shown in fig. 1, the pan-tilt driving method includes:
S101, determining a forbidden function of the shooting terminal according to mode control information of the shooting terminal.
In this embodiment, the mode control information may be generated by the user operating the control terminal (for example, by the user operating an application program (APP) associated with the photographing terminal running on the control terminal), and transmitted to the photographing terminal by the control terminal, or may be generated by the user operating the photographing terminal, which is not limited in this embodiment.
The mode control information may instruct the photographing terminal to turn on a certain functional mode or may instruct the photographing terminal to switch from one functional mode to another functional mode. The mode control information may be in the form of protocol messages. The disable function may indicate a function that is not available in the mode to be turned on or to be switched as indicated by the mode control information.
Optionally, in an embodiment of the present application, determining, according to mode control information of the photographing terminal, a disabling function of the photographing terminal includes:
s1011, determining the available state of at least one function in a first mode indicated by the mode control information according to the mode control information of the shooting terminal and a preset capability table.
In this embodiment, the preset capability table depends on the states of the state machine, the cradle head and the algorithm. The state machine refers to a mode of the photographing terminal. The preset capability table records a series of corresponding relations between modes and functions. For example, in mode a, the photographing terminal supports function 1, function 2, and function 3, and in mode B, the photographing terminal supports only function 1. It should be noted that, as with other functions, the cradle head and the algorithm are part of the functions of the shooting terminal, and information such as whether each function of the cradle head is enabled in a corresponding mode, whether each algorithm is enabled in a certain mode, and the like is recorded in the preset capability table. The preset capability table may be maintained by a separately provided module of the photographing terminal, so that when the subsequent preset capability table needs to be changed, firmware upgrade only needs to maintain the module. For convenience of description hereinafter, a module for maintaining a preset capability table may be referred to as a capability management module, which may serve as a cell phone interconnect (phone), user Interface (UI), WIFI, or bluetooth module, etc.
The first mode refers to a mode to be turned on or switched when the mode control information indicates that it is about to be turned on or switched. The available status may include available or unavailable, with function available indicating that the function is supported in the corresponding mode, and function unavailable indicating that the function is not supported in the corresponding mode. For example, in mode a, the photographing terminal supports function 1, function 2, and function 3, and in mode B, the photographing terminal supports only function 1, and in mode a, functions 1, 2, and 3 are all available, and in mode B, functions 1, 2, and 3 are not available.
In an optional implementation manner, according to the mode control information of the photographing terminal and the preset capability table, determining the available state of at least one function in the first mode indicated by the mode control information may include:
invoking an algorithm to start a first mode according to the mode control information of the shooting terminal, and obtaining effective information for indicating the successful start of the first mode; and matching in a preset capability table according to the effective information and the mode name of the first mode, and determining the available state of at least one function in the first mode.
For example, after the mode control information of the photographing terminal is acquired, the mode control information is parsed, and when the mode control information indicates that the photographing terminal switches from the mode a to the mode B, the mode B may be referred to as a first mode. At this time, the shooting terminal calls an algorithm starting mode B, matches in a preset capability table according to the mode name and the effective information of the mode B after obtaining the effective information of the mode B which is successfully started, and determines that only the function 1 is supported in the mode B, and the function 2 and the function 3 are not supported, so that the function 1 can be obtained and the function 2 and the function 3 can not be obtained.
S1012, determining a function that is not available among at least one function in the first mode as a disabled function of the photographing terminal.
After determining the available state of at least one function in the first mode, a function that is not available among the at least one function in the first mode is determined as a disabled function of the photographing terminal. For example, function 2 and function 3 in mode B are determined as disabled states of the photographing terminal.
S102, adjusting interaction controls corresponding to the disabling function to be in a disabling state in a user interface of the shooting terminal.
After determining the disabled function, the interactive control corresponding to the disabled function may be adjusted to a disabled state in a user interface of the control terminal to explicitly indicate to the user that the interactive control is not available in the current mode.
And S103, generating function disabling information for identifying the disabled function, and sending the function disabling information to a control terminal connected with the shooting terminal, so that the control terminal adjusts the interaction control corresponding to the disabled function to be in a disabled state in a user interface of the control terminal according to the function disabling information.
In this embodiment, after determining the disabled function, the function disabling information identifying the disabled function may be generated from the disabled function. For example, the function name of the disabled function may be directly encapsulated to generate the disabled information, or the mode name of the first mode and the function name of the disabled function may be encapsulated to generate the disabled information, or the disabled information may be generated in other manners, which is not limited in this embodiment. In a specific implementation, generating the function disabling information for identifying the disabled function may include: setting a capability value of a disabled function; and packaging the capability value of the forbidden function and the function name of the forbidden function to generate the function forbidden information. Optionally, the function disabling information may further include a name of the current mode, for example, a name of the current mode, a capability value of the disabling function in the current mode, and a function name of the disabling function are encapsulated, so as to generate the function disabling information.
In the embodiment of the application, the disabling function in the corresponding mode indicated by the mode control information is determined according to the mode control information of the shooting terminal, and the shooting terminal and the control terminal adjust the interaction control corresponding to the disabling function to be in the disabling state in the respective user interfaces according to the determined disabling function, so that the user interfaces of the shooting terminal and the control terminal are kept consistent, and the user experience is improved.
In addition, in the embodiment of the application, the user interface is controlled only according to the determined disabling function in the corresponding mode indicated by the mode control information, and the user interface can be controlled without knowing specific service logic, operation modes and real-time states of each functional module such as an algorithm, a cloud deck, media and the like, so that access and control dependence on each functional module is reduced. Furthermore, as only the preset capability table in the capability management module is required to be modified, the preset functional module is enabled, the product function can be realized without changing other programs, and the follow-up assembly and matching of the function of the shooting terminal are facilitated.
In this embodiment, S103 may be performed after S102 is performed, S102 may be performed after S103 is performed, or S102 and S103 may be performed simultaneously, which is not limited in this embodiment.
In order to facilitate understanding of the present application, a state synchronization method of an interactive control provided in the present application is described in detail below by using two specific examples. It should be noted that, as shown in fig. 2, in two examples provided below, the state synchronization method of the interactive control provided in the foregoing embodiment is performed by a phosphalink module 201 and a capability management module 202 in a capturing terminal 200, where the capturing terminal 200 communicates with the control terminal 100 through the phosphalink module 201, and the capability management module 202 maintains a preset capability table.
In the first example, the control terminal 100 controls the photographing terminal 200 to turn on the tracking mode. In this example, the state synchronization method of the interactive control may include the steps of:
and S301, the phosphalink module receives a protocol message sent by the control terminal, and the protocol message indicates that the tracking mode is started.
S302, the phosphalink module analyzes the protocol message, calls the algorithm module to start tracking, and reports the acquisition capability event.
Specifically, the phosphalink module analyzes the protocol message to obtain a start tracking mode command, and synchronously invokes a start tracking function to the algorithm module according to the start tracking mode command. After the tracking mode is turned on and the result is returned, the phosphalink module reports a request to the capability management module to acquire a capability event, where the event carries a mode name and an effective parameter, for example, (start_track, 1), where start_track indicates that tracking is started, and 1 indicates that tracking is started.
And S303, setting the corresponding capacity by the capacity management module according to the information in the corresponding preset function table, and assembling and releasing the event.
In this embodiment, the capability management module receives the capability value acquisition event, and the event analysis unit in the capability management module analyzes the capability value acquisition event to obtain a mode name and an effective parameter, for example, obtain (start_track, 1). And then matching is carried out in a preset function table according to the mode name and the effective parameters, and the mode is matched to support sensitivity setting in a tracking mode, and not support cradle head centering, mode setting and the like. If the previous state supports all the functions, the capability management module disables functions that are not currently supported, such as a cradle head return-to-center function, a mode setting function, and the like, and simultaneously packages the events of the functions that are not currently supported and issues the events to the phone link module.
S304, the Phonellnk module receives the event, analyzes the event, assembles the Json message and sends the Json message to the control terminal.
Specifically, the phosphalink module analyzes the received event, assembles a Json message according to the function which is not supported currently and the necessary parameters communicated with the control terminal, and sends the Json message to the control terminal, so that the control terminal can obtain the function which is not supported currently through analyzing the Json message, and updates the user interface of the control terminal, thereby enabling the cradle head centering function and the mode setting function to be in a disabled state in the user interface of the control terminal and the user interface of the shooting terminal.
In the second example, the control terminal 100 controls the photographing terminal 200 to switch to the 4K60fps mode. In this example, the state synchronization method of the interactive control may include the steps of:
s401, the phosphalink module receives a shooting terminal to send a protocol message, and the protocol message instructs to switch to a 4K60fps mode.
S402, the phosphalink module analyzes the protocol message, calls a media resolution switching function to the algorithm module, and reports the event acquisition capability.
In this embodiment, the photographing terminal analyzes the protocol message to obtain an analysis result, and the analysis result instructs the photographing terminal to switch to the 4K60fps mode. After the analysis results in a switching command to 4K60fps, the photo link module of the photographing terminal invokes media resolution switching to the algorithm module of the photographing terminal. Specifically, the phosphalink module sends a request for switching to 4K60fps to the media of the photographing terminal, and after the request is successful, the phosphalink module reports an acquisition capability value event and reports a switching completion event after the switching is completed.
S403, the capacity management module analyzes the switching completion event, sets the corresponding capacity according to the information in the corresponding preset function table, assembles and issues the event.
Specifically, if the switching is not completed, the capacity management module cannot be matched with the corresponding form and does not respond. If the switching is completed, the capacity management module receives a switching completion event, and at this time, the capacity management module analyzes the switching completion event to obtain that the switching is switched to the 4K60fps shooting mode. At this time, the capability management module of the shooting terminal performs matching in a preset function table according to the analyzed mode name and the effective parameters, and the matching is that the functions of pan-tilt tracking, tracking algorithm, digital zooming and the like are not supported in the 4K60pfs shooting mode. If the previous state supports all the functions, the capability management module disables the functions which are not supported currently, and simultaneously packages the events of the functions which are not supported currently, and issues the events to the phone link module.
S404, the Phonellnk module receives the event, analyzes the event, assembles the Json message and sends the Json message to the control terminal.
Specifically, the phosphalink module analyzes the received event, assembles a Json message according to the function which is not supported currently and the necessary parameters communicated with the control terminal, and sends the Json message to the control terminal, so that the control terminal can obtain the function which is not supported currently through analyzing the Json message, and updates the user interface of the control terminal, thereby enabling the pan-tilt tracking function to be in a disabled state in the user interface of the control terminal and the user interface of the shooting terminal. Specifically, as shown in fig. 5, since the system specifies that the pan-tilt tracking function is not available in the 4K60fps mode, the object tracking function of the control terminal at 60fps/4K is displayed disabled (shown in phantom) by the state synchronization method of the interactive control provided by the present embodiment after the photographing terminal is connected to the control terminal.

Thus, particular embodiments of the present subject matter have been described. Other embodiments are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may be advantageous.
In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented with "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before being compiled is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but HDL is not only one, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circ user interface t Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circ user interface t, ASIC), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

It will be understood that each flow and/or block of the flowchart illustrations and/or block diagrams, and combinations of flows and/or blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

Accordingly, the present application may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present application may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular transactions or implement particular abstract data types. The application may also be practiced in distributed computing environments where transactions are performed by remote processing devices that are connected through a communications network.
