In order to facilitate understanding of the present application by those skilled in the art, an underlying framework for accessing the camera is described below by taking an Android operating system as an example. As shown in fig. 1, a camera class program accesses a camera through an underlying framework 101, and the underlying framework 101 includes an application framework layer 102, a camera service layer 103, and a hardware abstraction layer 104.
As shown in fig. 1, the Application framework layer 102 provides Application Programming Interface (API) functions (Android ware camera2.0 camera device and Android ware camera2.0 camera manager) and a binding Binder Interface (Android ware camera2.0 icamera device and Android ware camera2.0 icamera service), so that the camera class program can access the camera by calling the API functions and then calling the Binder Interface.
In addition to the Binder interface provided by the application framework layer 102, the icaramdevicallbacks and icaramservicelistener in the camera service layer 103 are also Binder interfaces, wherein the Android hardware camera2.0 icaramdeviceuser in the application framework layer 102 is an interface of an opened specific camera device, and the Android hardware camera2.0 icaramservice is an interface of a camera service.

HAL104 defines the interface functions called by camera services layer 103, and is not described herein again because it is prior art.
The bottom layer frame shown in fig. 1 is only an illustration, the bottom layer frame described in the present application is not limited to the structure described in fig. 1, and other bottom layer frames capable of implementing camera call are also within the scope of the present application.
The technical solution described in the present application is described below by specific examples.
Example one
In the following, a camera access method provided in an embodiment of the present application is described, where the camera access method is executed by a camera program, please refer to fig. 2, and the method includes:
in step S201, if an instruction to start a camera program is received, requesting a bottom layer frame for a cache pipe BQ, where the bottom layer frame is a program frame for accessing a camera, the BQ is used for caching an image acquired by a target camera, and the target camera is a camera to be accessed;
in this embodiment of the application, the instruction for starting the camera class program may be considered to be received when the user starts the camera APP, or starts a "video call" function in the instant messaging application, or may also be received when starting a "camera" function in the online shopping platform, and a scene for receiving the instruction for starting the camera class program is not limited in this application.
When the terminal equipment receives the camera program starting instruction, a cache pipeline BQ is requested from the bottom layer framework, and the cache pipeline BQ is used for caching the image collected by the camera to be accessed. The underlying frame described in this step S201 may be as shown in fig. 1.
In the prior art, when a terminal device receives an instruction to start a camera-like program, two BQs are requested from a bottom layer frame, one BQ is used for displaying a preview picture, and the other BQ is used for acquiring a photographed image. Unlike the prior art, the present application only requests a BQ from the underlying frame, which is used for both the preview screen display and the captured image acquisition.
In step S202, displaying a preview image based on the image captured by the target camera cached by the BQ;
in the embodiment of the present application, the BQ requested in step S201 is used for displaying a preview screen. In this step S202, the image captured by the target camera cached in the BQ may be directly displayed as a preview screen; or the image processing (such as processing of adding a filter, beautifying a face, and/or adding a sticker) may be performed on the image acquired by the target camera cached by the BQ to obtain an image after the image processing, and then the image after the image processing is displayed as a preview image.
In step S203, if a photographing instruction is received, acquiring a photographed image from the image cached in the BQ at a time corresponding to the photographing instruction;
in the embodiment of the present application, the photographed image is also derived from the BQ requested in step S201. Compared with the prior art, the BQ occupying the storage space is reduced, and then the pause phenomenon of the terminal equipment when the terminal equipment takes a picture for a long time can be lightened to a certain extent.
In addition, in this embodiment of the application, the step S203 may specifically include: and taking the preview picture at the moment corresponding to the photographing instruction as a photographed image.
That is, after the photographing instruction is received, the preview picture at the current moment is directly used as the image obtained by photographing, and the problem that the camera program communicates with the bottom layer framework again after the photographing instruction is received is avoided, so that the size of the camera program can be reduced on one hand, the photographing efficiency can be improved to a certain extent on the other hand, the long time consumption for obtaining the image obtained by photographing is avoided, and on the other hand, the data processing amount of the terminal equipment can be reduced, and the power consumption of the terminal equipment is reduced.
In the prior art, when a photographing instruction is received, a camera program first sends the photographing instruction to a bottom layer framework, and then a BQ for photographing acquires an image acquired by a camera and takes the image as a photographed image. In the embodiment of the application, if the preview picture is directly taken as the photographed image, on one hand, the occupied amount of the storage space is reduced due to the fact that BQ special for photographing is avoided, on the other hand, the camera program and the bottom layer frame are prevented from communicating again during photographing, and the photographing efficiency is improved.
Further, the above-mentioned "photographing instruction corresponding timing" means: and the time which is less than the preset time length away from the time point of the photographing instruction sent by the user. For example, if the user sends the photographing instruction at the time a, and the preset time is 2ms, any time that is less than 2ms away from the time a may be the "photographing instruction corresponding time".
In the embodiment of the present application, if the photographed image is a preview screen, the Exchangeable image file format (exif) information of the photographed image is determined in a manner that: and analyzing the image parameter information of the preview image corresponding to the photographed image. For example, if the photographed image is an image X and the image X is a preview screen Y, the image parameter information (for example, information such as image size) of the preview screen Y may be analyzed to obtain exif information of the image X, and the exif information may be written in a header file of the image X.
Furthermore, after the step S203, the photographed image obtained in the step S203 may be subjected to image processing, such as size modification, filter addition, face beautification and/or sticker addition, to obtain a final photographed image.
In this embodiment of the present application, the camera program may have a video recording function, and the camera access method provided in this embodiment may further include: and if a video recording instruction is received, directly integrating all preview pictures in the video recording period to generate a video file. In addition, the camera program may also provide a photographing function during recording, and step S203 may specifically include: and if a photographing instruction is received during the video recording, acquiring the image obtained by photographing at the image cached in the BQ at the moment corresponding to the photographing instruction.
Therefore, according to the camera access method provided by the embodiment of the application, only one Buffer Queue (BQ) is requested from the bottom layer frame, and the BQ is used for displaying the preview picture on one hand and for taking a picture on the other hand.
In order to make the technical solutions provided in the present application more clearly understood, a schematic diagram of a framework structure for camera access is further described below based on fig. 3. As shown in fig. 3, the camera program realizes access to the camera by calling the underlying framework, wherein the camera program includes a parameter configuration module, a camera control module, a view display control module, a video component, a file saving module, and the like. The parameter configuration module is mainly used for configuring parameters such as the display frame rate of a preview picture, the video frame rate and the like; the camera control module is used for controlling parameters such as an identifier of a camera to be opened and an identifier of a camera to be closed; the view display control module is used for controlling display controls, hidden spaces and the like on a display interface; the file storage module is used for storing video files obtained by video recording and images obtained by photographing; the video recording component is used for integrating the preview images subjected to special effect processing to obtain a video file.
Further, as shown in fig. 3, the camera program realizes the display function of the preview screen, the video recording function, and the photographing function by one BQ. However, in the prior art, the photographing function often needs to call another BQ (such as the BQ shown in the gray part in fig. 3) to the bottom layer frame, and then after a series of image processing is performed on the image stored in the BQ (such as the processing 1 ', the processing 2', and the processing N 'shown in the gray part in fig. 3, where the processing 1' may be for beautifying the portrait, the processing 2 'may be for adding a sticker, and the processing N' may be for adding a filter), the photographed image is obtained.
Obviously, when the camera program shown in fig. 3 performs camera access, only one BQ is needed to simultaneously perform photographing, recording and previewing, so that the method occupies less storage space compared with the prior art, and therefore, the problem that the camera program is stuck for photographing for a long time can be solved to a certain extent. In addition, as shown in fig. 3, the photographed image is actually a preview image, so that the process that a conventional camera program needs to communicate with the bottom layer frame again is avoided, and the problem of photographing delay can be solved to a certain extent, so that the photographed image is obtained more quickly, the data processing amount of the terminal device is reduced, and the photographing power consumption of the terminal device is reduced.
