In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic implementation flow diagram of a method for invoking a camera according to an embodiment of the present application, where as shown in the figure, the method may include the following steps:
step S101, monitoring whether an application program in the mobile terminal sends a calling request for calling a camera.
In the embodiment of the present application, a plurality of application programs having a right to call a camera may be installed in a mobile terminal such as a mobile phone, for example, some application programs having a code scanning function and some application programs having a beauty and photo taking function, the application programs may all need to call a camera in the mobile terminal in actual use, the camera of the mobile terminal includes a hardware module and a software system, and after the software system of the camera is upgraded, some APIs may also be changed accordingly, so that after the software system of the camera is upgraded, some application programs may not call the camera, or the application programs may need to upgrade themselves to call the camera so as to call the camera. However, some application publishers may not modify their own software systems in time, and therefore, there is a need to provide middleware by which even non-upgraded applications can invoke upgraded cameras. In order to implement the above functions, the middleware needs to monitor whether an application program in the mobile terminal sends a call request for calling the camera.
Step S102, if it is monitored that an application program in the mobile terminal sends a call request for calling a camera, first information is generated based on the call request, and the data frame format of the first information is the data frame format supported by the camera of the mobile terminal.
In the embodiment of the application, if it is monitored that an application program in the mobile terminal sends a call request for calling a camera, the call request may be intercepted or not intercepted, for example, it is determined whether a data frame format of the call request is consistent with a data frame format supported by the camera of the mobile terminal, if so, no interception is needed, and also no middleware is needed to convert the call request into first information supported by the camera of the mobile terminal, if not, interception may be performed, and first information is generated based on the call request, and of course, a data format of the generated first information is the data frame format supported by the camera of the mobile terminal.
Step S103, sending the first information to the camera to instruct the camera to return a corresponding preview image according to the first information.
In this embodiment of the application, after the middleware converts the call request into the first information that can be supported by the camera, the first information can be sent to the camera instead of the call request, the camera can return a corresponding preview image according to the first information after receiving the first information that can be identified, the camera can return the preview image to the middleware, the middleware returns the preview image to the application program that calls the camera, and the application program side can perform related operations such as code scanning recognition and beauty treatment after receiving the preview image. In practical applications, the camera may also directly return the preview image to the application program currently running in the foreground, so that the preview image is indirectly sent to the application program calling the camera without using middleware as a relay.
The middleware provided by the embodiment of the application can monitor that an application program sends a calling request for calling a camera in the mobile terminal, the calling request of the application program is converted into first information supported by the camera of the mobile terminal, and the camera is indicated by the first information to return corresponding preview images according to the first information, so that even if a camera system is upgraded, the calling request sent by some application programs cannot be identified by an interface possibly after the upgrading, however, the calling request which cannot be identified by the camera system can be converted into the first information which can be identified by the camera through the middleware, so that the camera system can return corresponding preview images according to the first information, and the problem that the application program is incompatible when the camera is called to preview images or take pictures after the system of the camera is upgraded is solved.
Fig. 2 is a schematic implementation flow diagram of another method for invoking a camera according to an embodiment of the present disclosure, where as shown in the figure, the method may include the following steps:
step S201, monitoring whether an application program in the mobile terminal sends a call request for calling a camera.
The content of step S201 is consistent with that of step S101, and the description of step S101 may be specifically referred to, which is not repeated herein.
Step S202, if it is monitored that an application program in the mobile terminal sends a calling request for calling a camera, a configuration file of the application program sending the calling request is obtained, and whether the application program is compatible with the camera of the mobile terminal is determined based on the configuration file.
Step S203, if the application program is not compatible with the camera of the mobile terminal, generating first information based on the calling request.
In the embodiment of the present application, the embodiment shown in fig. 1 describes that whether to convert the call request into the first information may be determined by comparing a data frame format of the call request with a data frame format supported by the camera, and in the embodiment of the present application, it may be determined whether the application is compatible with the camera of the mobile terminal by obtaining a configuration file of the application that issues the call request, and if so, the call request does not need to be converted into the first information. If not, first information needs to be generated based on the calling request.
Certainly, in practical application, the configuration file of the application program having the authority to call the camera may also be periodically scanned, an application program list that needs to convert the call request into the first information is generated, and the update may be performed at preset intervals. Therefore, if it is monitored that an application program in the mobile terminal sends a call request for calling a camera, it is only necessary to determine whether the application program sending the call request is in the application program list, and if the application program sending the call request is in the application program list, the call request is generated into first information, and if the application program sending the call request is not in the application program list, the call request does not need to be processed, and the camera can recognize the call request.
As another embodiment of the present application, the generating the first information based on the invocation request includes:
and acquiring preset shooting parameters from the calling request of the application program or a configuration file based on the calling request, and generating first information according to the preset shooting parameters, wherein the first information is used for indicating the camera to modify hardware parameters of the camera according to the preset shooting parameters, and returning a preview image matched with the preset shooting parameters.
In the embodiment of the present application, since different applications may need to set different shooting parameters based on their respective functional requirements, for example, shooting parameters of code scanning software and shooting parameters of beauty software may be different, and these shooting parameters are usually stored in a configuration file, and some applications may also encode corresponding shooting parameters into a call request. The middleware may obtain a preset shooting parameter from the call request of the application program or from the configuration file, and generate the first information according to the preset shooting parameter, and of course, a data frame format of the first information including the preset shooting parameter also needs to conform to a data frame format supported by the camera.
Step S204, the first information is sent to the camera to indicate the camera to return a corresponding preview image according to the first information.
In the embodiment of the application, after first information containing preset shooting parameters is obtained, the first information containing the preset shooting parameters can be sent to the camera, the camera can modify hardware parameters of the camera according to the preset shooting parameters after receiving the first information, and preview images are collected through the camera after the hardware parameters are modified, namely the returned preview images are images matched with the preset shooting parameters.
In practical application, after the camera receives the first information, the camera may also obtain the preset shooting parameters from the configuration file of the corresponding application program according to the first information. And then, modifying the hardware parameters of the camera according to the preset shooting parameters, and acquiring a preview image through the camera after the hardware parameters are modified.
Fig. 3 is a schematic implementation flow diagram of another method for invoking a camera according to an embodiment of the present disclosure, where as shown in the figure, the method may include the following steps:
step S301, monitoring whether an application program in the mobile terminal sends a calling request for calling a camera.
Step S302, if it is monitored that an application program in the mobile terminal sends a call request for calling a camera, preset shooting parameters are obtained from the call request of the application program or a configuration file based on the call request.
Step S301 and step S302 can refer to the related descriptions in the embodiments shown in fig. 1 and fig. 2, and are not described herein again.
Step S303, generating a first information queue according to the preset shooting parameters, and sequentially sending the first information in the first information queue to the camera at preset time intervals, so as to instruct the camera to return a preview image matched with the preset shooting parameters according to each received first information.
In this embodiment, in order to simplify communication between the middleware and the application program, a first information queue may be generated according to the preset shooting parameter, that is, a plurality of first information are generated, the plurality of first information are sequentially sent to the camera at a preset time interval, and the camera returns a preview image every time it receives one first information. In this way, an uninterrupted preview image is obtained through the middleware once the application begins to call the camera. In this way, the user can see a real-time preview image on the application side. The first information transmitted at this time includes preset shooting parameters, which can also be understood as shooting parameters initialized by the application program.
Of course, in the actual use of the application program, there may be a function of modifying the shooting parameters based on the user's requirements, and the application program may send a request for modifying the shooting parameters; the beauty photography software may also want to obtain not only preview images but also photographs, so the application may also issue a photograph request for photography; of course, if the first message in the first message queue is sent to the camera without interruption, the preview image is returned without interruption, and the application may also have a request to stop the preview. The following description is made by way of the above examples.
Step S304, if a modification request of the shooting parameters is monitored, a first information queue is regenerated based on the shooting parameters to be modified corresponding to the modification request, first information in the first information queue is sequentially sent to the camera at preset time intervals so as to instruct the camera to modify hardware parameters of the camera according to the shooting parameters to be modified, and a preview image matched with the modified shooting parameters is returned according to each piece of first information.
In the embodiment of the present application, a user may modify some shooting parameters in an interface of an application, for example, adjust a focal length, turn on a blurring function, and the like. If the middleware monitors the modification request of the shooting parameters, the middleware indicates that a user possibly wants to modify the initialized shooting parameters into the shooting parameters required by the user, the shooting parameters are recorded as the shooting parameters to be modified, the middleware regenerates the first information queue according to the shooting parameters to be modified, and the original first information queue (containing the initialized shooting parameters) is emptied. And continuously and sequentially sending the first information in the first information queue generated based on the shooting parameters to be modified to the camera at preset time intervals so as to instruct the camera to modify the hardware parameters of the camera according to the shooting parameters to be modified, and returning a preview image matched with the modified shooting parameters according to each piece of first information.
It should be noted that, each time a modification request of the shooting parameters is monitored, the first information queue needs to be regenerated according to the shooting parameters expected to be modified, and the original first information queue needs to be deleted, two storage spaces can be allocated, the first storage space stores a first information queue and sends the first information in the first storage space to the camera, if the modification request of the shooting parameters is monitored, the first information queue is regenerated in the second storage space according to the shooting parameters to be modified, after the first information with the first preset quantity is generated in the second storage space, the first information queue of the second storage space is covered on the first information queue of the first storage space, and after the quantity of the first information in the information queue of the first storage space is smaller than the second preset quantity, the first information continues to be generated in the first storage space.
Step S305, if it is monitored that the application program calling the camera sends out a photographing request for photographing, second information is generated based on the photographing request and sent to the camera, the data frame format of the second information is the data frame format supported by the camera of the mobile terminal, the second information comprises format parameters of an image requested to be returned by the camera, and the priority of the second information is higher than that of the first information.
In this embodiment of the application, if it is monitored that the application calling the camera sends a photographing request for photographing, the middleware may generate second information, where the second information is obtained by adding a format parameter of an image requested to be returned by the camera to the first information, that is, by adding a piece of data to the first request, where the piece of data includes the format parameter of the image requested to be returned by the camera, and usually defaults to an image format, and after monitoring that the application calling the camera sends a photographing request for photographing, the middleware generates second information, where the second information is obtained by adding the format parameter of the image to the first information. The camera, upon receiving the second information, may return an image in a particular format. Of course, the second information has a higher priority than the first information, i.e. once the second information is generated, it is sent to the camera in preference to the next first information to be sent.
Step S306, if an exit instruction of the application program of the camera or an instruction of stopping the preview is monitored, terminating the sending of the first information.
In this embodiment of the application, if the middleware monitors an exit instruction of an application program calling the camera or an instruction of stopping preview, it indicates that the user no longer needs to use the camera. The second information corresponding to the photographing request is the sending of the single information and the returning of the single photo, while the first information corresponding to the calling request is sent uninterruptedly and returned uninterruptedly, so that if the user does not need to use the camera any more, the sending of the first information needs to be terminated, and the preview image can not be returned any more.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
