The system software/service/module of the electronic equipment determines the physical camera corresponding to the logic camera to be started by the application program according to the folding form of the electronic equipment, so that the development cost of the application program can be reduced.
In a first aspect, an embodiment of the present application provides a shooting method, which is applied to an electronic device, where the electronic device includes a first screen and a second screen that are located on different sides of the electronic device, where the first screen is a folded screen, at least one first physical camera is disposed on a same side of the first screen, and at least one second physical camera is disposed on a same side of the second screen; and the method comprises the following steps: the method comprises the steps that a first application receives a shooting instruction of a second application, wherein the shooting instruction comprises a shooting visual angle identifier, and the shooting visual angle comprises front shooting and rear shooting; the first application determines physical cameras for completing shooting instructions according to shooting visual angle identifiers, folding forms of a first screen and corresponding relations of all physical cameras and shooting visual identifiers of the first screen stored in advance under different folding forms; the second application completes shooting instructions through the determined physical cameras; wherein the second application is independent of the first application.
In this embodiment of the present application, a first application in the electronic device (for example, system software/service/module/system application of the electronic device, such as a camera provider below) determines, according to a folding status of a folding screen (first screen) of the electronic device, a physical camera corresponding to the same capturing view identifier (that is, a logical camera identifier below, such as a logical front-end camera identifier, a logical rear-end camera identifier, etc.), so that the second application may collect an image/video through the determined corresponding physical camera. Therefore, a developer of the second application does not need to develop a command for responding to the physical camera of the same shooting visual angle identification according to the folding form of the folding screen of the electronic equipment, and development cost is reduced.
In one possible implementation manner of the first aspect, the determining, by the first application, the physical camera for completing the shooting instruction according to the shooting view angle identifier, the folding form of the first screen, and the corresponding relationship between each physical camera and the shooting visual identifier of the first screen in different folding forms, where the corresponding relationship is stored in advance, includes: the first application determines that a shooting instruction is finished through a first physical camera under the condition that a shooting visual angle mark is a front shooting mark and a first screen is in an unfolding state; and the second application determines that the shooting instruction is finished through the second physical camera under the condition that the shooting visual angle identifier is the front shooting identifier and the first screen is in a folded state.
In a possible implementation of the first aspect, the method further includes: and under the condition that the folding form of the first screen is changed, the first application switches the physical camera for completing the shooting instruction.
In one possible implementation manner of the first aspect, the switching, by the first application, the physical camera for completing the shooting instruction in a case where a folding morphology of the first screen changes, includes: under the condition that a first screen is switched from an unfolding state to a folding state, a first application switches a physical camera for completing shooting instructions from the first physical camera to a second physical camera; and under the condition that the first screen is switched from the folded state to the unfolded state, the first application switches the physical camera used for completing the shooting instruction from the second physical camera to the first physical camera.
In other words, if the folding form of the first screen of the electronic device changes during the process that the second application collects images or videos through the determined physical camera, the first application can switch the corresponding physical camera according to the changed folding form of the electronic device. Therefore, after the folding form of the electronic equipment is changed, the second application still collects images or videos through the physical cameras corresponding to the folding form of the electronic equipment before the folding form is changed, and user experience is improved.
In a possible implementation manner of the first aspect, the electronic device further includes at least one third physical camera disposed on a different side from the first screen; and the method further comprises the steps of: the first application determines that a shooting instruction is finished through a third physical camera and/or a second physical camera under the condition that a shooting visual angle mark is a post shooting mark and a first screen is in an unfolding state; and the first application determines that the shooting instruction is finished through the third physical camera under the condition that the shooting visual angle mark is a post shooting mark and the first screen is in a folded state.
The electronic device uses a third physical camera to complete a shooting instruction when the first screen is in a folded state and uses the third physical camera and/or a second physical camera to complete the shooting instruction when the first screen is in an unfolded state when the shooting view angle of the second application is a rear shooting (i.e. when a logic rear camera is used to collect images or videos).
In a possible implementation of the first aspect, the method further includes:
under the condition that the first application is abnormal and restored, the physical cameras for completing shooting instructions are redetermined based on shooting view angle identifiers, folding forms of the first screen and corresponding relations of the physical cameras and the shooting view angle identifiers of the first screen stored in advance under different forms.
That is, under the condition that the first application is abnormal and restored, for example, after the first application cannot continue to provide service for restarting, the first application can redetermine the physical camera for completing the shooting instruction based on the shooting visual angle identifier, the folding form of the first screen and the corresponding relation between each physical camera and the shooting visual angle identifier of the first screen stored in advance under different forms, so that the situation that the second application cannot acquire images or videos through the correct physical camera due to restarting of the first application is avoided, and user experience is improved.

Detailed Description
Illustrative embodiments of the present application include, but are not limited to, a photographing method, a readable medium, and an electronic device.
The following describes the technical scheme of the embodiments of the present application with reference to the accompanying drawings.
For easy understanding, an electronic device to which the photographing method provided in some embodiments of the present application is applicable will be described first.
It is understood that the physical camera mentioned in the present application refers to an entity camera installed on an electronic device or externally connected to the electronic device. In some embodiments, different physical cameras/camera units typically have different physical camera identifications through which applications in the electronic device may invoke corresponding physical cameras to capture image data.
It can be appreciated that, compared to the above-mentioned physical camera, the logic camera mentioned in the application is a conceptual camera for different usage fields Jing Dingyi, and according to the application of the user with the image capturing or video capturing function on the electronic device, when capturing images or videos, the physical camera capturing directions are different, and the logic camera can be divided into a logic front-mounted camera (such as a front-mounted capturing view angle and a logic rear-mounted camera (such as an inward-mounted capturing view angle and a capturing direction of a display screen currently used by the user in the electronic device).
It will be appreciated that in other embodiments, the logic camera may also include other types of logic cameras, such as a logic depth camera for capturing 3-dimensional images, as determined by the function of the camera, without limitation.
Specifically, for example, fig. 1 illustrates a schematic structural diagram of a foldable cellular phone 100, according to some embodiments of the present application; FIG. 2A illustrates a schematic view of the front side (A side of FIG. 1) of a cellular telephone 100 in an expanded state, according to some embodiments of the present application; FIG. 2B illustrates a schematic view of the back side (the B/C side of FIG. 1) of a cellular telephone 100 in an expanded state, according to some embodiments of the present application; fig. 3A illustrates a schematic view of the front side (C side shown in fig. 1) of a cellular phone 100 in a folded state, according to some embodiments of the present application; fig. 3B illustrates a schematic view of the back side (B side shown in fig. 1) of the mobile phone 100 in a folded state, according to some embodiments of the present application.
When the mobile phone 100 is in the unfolded state, that is, when the folding screen 1941 is in the unfolded state, referring to fig. 1 and 2A, the logical front camera of the mobile phone 100 is a camera unit 1931, and referring to fig. 2B, the logical rear camera of the mobile phone 100 is a camera unit 1933; when the mobile phone 100 is in the folded state, that is, the folding screen 1941 is in the folded state, referring to fig. 3A, the logical front camera of the mobile phone 100 is the camera unit 1932, and referring to fig. 3B, the logical rear camera of the mobile phone 100 is the camera unit 1933. Therefore, the same physical camera can be used as a logic front camera or a logic rear camera under different use scenes.
It will be appreciated that a folding screen is a foldable, bendable display screen made of a flexible material, such as a flexible screen made of Organic Light-Emitting diodes (OLED), or the like.
It should be understood that the foregoing structure and configuration of the mobile phone 100 are merely examples, and that in other embodiments, the mobile phone 100 may be other types of foldable electronic devices, such as the mobile phone 100 folded along the M-M direction B/C plane shown in fig. 1, which is not limited herein.
It will be appreciated that the aforementioned unfolded state and folded state of the mobile phone 100 are merely examples, and in some embodiments, when the included angle between the left half screen and the right half screen of the display 1941 is greater than the preset unfolded angle, it may be determined that the mobile phone 100 is in the unfolded state; when the included angle between the left half screen and the right half screen of the display 1941 is smaller than the preset folding angle, it is determined that the mobile phone 100 is in the folded state, which is not limited herein.
It should be understood that the foregoing distribution of the camera units of the mobile phone 100 is merely an example, and in other embodiments, the mobile phone 100 may include more or fewer camera units, and the camera units may be disposed at other positions of the mobile phone 100, which is not limited herein.
It is understood that a camera unit may include any number of cameras, for example, camera unit 1931 may include a conventional camera for capturing 2-dimensional images and a depth camera for capturing 3-dimensional images.
As described above, when the mobile phone 100 is processed in different modes, the logical front-end camera of the mobile phone 100 is a different physical camera, so that the application program installed in the mobile phone 100 needs to select the corresponding physical camera as the logical front-end camera of the mobile phone 100 according to the mode of the mobile phone 100. For example, referring to fig. 4A and 4B, when the user uses the camera application to perform self-photographing, the camera application selects the camera unit 1931 as a logical front camera when the mobile phone 100 is in an unfolded state, that is, acquires an image of the user through the camera unit 1931; when the mobile phone 100 is in the folded state, the camera unit 1932 is selected as a logical front camera, that is, an image of the user is acquired through the camera unit 1932.
That is, in order to ensure that the application program installed on the mobile phone 100 can use the corresponding physical camera to collect the image or video when the mobile phone 100 is in different forms (folded state and unfolded state), the developer of the application program needs to integrate and detect the form of the mobile phone 100 for each application program using the camera of the mobile phone 100, and select the corresponding physical camera as the instruction of the logical camera according to the form of the mobile phone 100, thereby increasing the development cost of the application program. For example, to keep referring to fig. 4A and fig. 4B, in order to ensure that when the camera application is used in the user's self-timer, the camera application can use the physical cameras disposed in the mobile phone 100 in both the unfolded state and the folded state, where the display screen currently used by the user is on the same side, the developer needs to integrate the form of the mobile phone 100 in the camera application, and determine the instruction of the physical camera corresponding to each logical camera in the current form of the mobile phone 100 according to the form of the mobile phone 100 and the correspondence between each logical camera and each physical camera in different forms of the mobile phone 100, so that the camera application can acquire images or videos through the camera unit 1931 in the folded state of the mobile phone 100 and acquire images or videos through the camera unit 1932 in the unfolded state of the mobile phone 100 in the operation process.
In view of this, the embodiment of the present application provides a shooting method, in which the system software of the mobile phone 100, such as a Camera Provider (Camera Provider), establishes the correspondence between the logic front-end Camera and the physical Camera and the correspondence between the logic rear-end Camera and the physical Camera when the mobile phone 100 is in different forms. Therefore, when an application program in the mobile phone 100 acquires an image or a video through the logic front camera or the logic rear camera, the system software of the mobile phone 100 can determine a physical camera of the application program for acquiring the image or the video according to the corresponding relation only by providing the identification of the logic front camera or the logic rear camera for the system software of the mobile phone 100, and the physical camera is started through the physical camera identification of the physical camera, so that a developer of the application program is not required to independently write and acquire the form of the mobile phone 100 for the application program, and the instruction of the physical camera corresponding to each logic camera is determined according to the form of the mobile phone 100, and the development cost of the application program is reduced.
For example, the mobile phone 100 includes 3 physical camera units, i.e., a camera unit 1931, a camera unit 1932, and a camera unit 1933, and the mobile phone 100 processes different modes, and the correspondence between each logical camera and each physical camera is shown in table 1:
Table 1 the mobile phone 100 is in different forms, and the correspondence table between each logical camera and each physical camera
Mobile phone 100 shape | Logic front camera (sign: 1) | Logic rear camera (sign: 0) |
Expanded state | Camera unit 1931 | Camera unit 1933 |
Folded state | Camera unit 1932 | Camera unit 1933 |
As shown in table 1, the system software of the mobile phone 100 may set the identifier of the logical front camera (front-end capturing identifier) to 1 and the identifier of the logical rear camera (rear-end capturing identifier) to 0, so that the application program on the mobile phone 100 may collect images or videos through the camera unit 1931 when the mobile phone 100 shown in fig. 4A is in the unfolded state, for example, referring to fig. 4A and 4B, and in the scenario where the user uses the camera to self-capture, the camera application provides the logical front camera identifier "1" to the system software of the mobile phone 100; when the mobile phone 100 is in the folded state shown in fig. 4B, the camera unit 1932 is used to collect images or videos, and the camera application developer does not need to integrate the instructions for collecting images or videos in the unfolded state of the mobile phone 100 and collecting images or videos in the folded state of the mobile phone 100 through the camera unit 1931 in the camera application, so that the development cost of the camera application is reduced.
It is to be understood that the correspondence between each logical camera and each physical camera in the mobile phone 100 shown in table 1 is merely an example, and in other embodiments, other correspondence may be also possible, for example, the logical post-camera may also include the camera unit 1932 in the unfolded state of the mobile phone 100, which is not limited herein.
It will be appreciated that the foregoing logical front-facing camera identification may be set to 1 as an example, and that in other embodiments, the logical front-facing camera identification may be other identifications, which are not limited herein.
It will be appreciated that in other embodiments, in the case where the mobile phone 100 is in a different configuration and uses a different physical camera as the logical post-camera, the system software of the mobile phone 100 may also provide a unified logical post-camera identifier, for example, 0, for the physical camera that may be used as the logical post-camera, so that an application in the mobile phone 100 may collect an image or video through a corresponding physical camera in a different configuration of the mobile phone 100 according to the logical post-camera identifier, which is not limited herein.
It will be appreciated that in the system software of the handset 100, the camera provider may provide services for applications in the handset 100 to access the interfaces of the various physical cameras/camera units of the handset 100. The following describes a technical solution of the embodiment of the present application taking a camera provider as an example to implement the system software of the embodiment of the present application.
Specifically, fig. 5 illustrates a flow diagram of a method of capturing images implemented by a camera provider, according to some embodiments of the present application. As shown in fig. 5, the process includes the steps of:
s501: a request is received for an application to start a camera.
That is, the camera provider triggers the shooting method provided in the embodiment of the present application when receiving a request of the application program to start the camera.
It will be appreciated that the request sent by the application program to start the camera includes a logical camera identifier to be started, for example, a logical front camera identifier, a logical rear camera identifier, a logical depth camera identifier, and the like. In some embodiments, the logical front camera identification may be set to 1 and the logical rear camera identification to 0.
Specifically, for the scenario illustrated in fig. 4A and 4B, the request sent by the camera provider to activate the camera that is received by the camera application may include the logical front-facing camera identification 1.
S502: the method comprises the steps of obtaining the form of the mobile phone 100, and determining a physical camera to be started according to the form of the mobile phone 100 and the logical camera identification.
That is, after receiving a request for starting a camera sent by an application program, a camera provider obtains a form of the mobile phone 100, and determines a physical camera corresponding to the logical camera identifier in the current form according to the form of the mobile phone 100 and the logical camera identifier in the request for starting the camera, and the correspondence between each logical camera and each physical camera of the mobile phone 100 in different forms.
For example, for the scenario shown in fig. 4A and 4B, a logical front-facing camera identification 1 may be included in the start-up camera request sent by the camera application to the camera provider. Referring to fig. 4A, when detecting that the mobile phone 100 is in the unfolded state, the camera provider determines that the physical camera corresponding to the logical front camera identifier 1 is a camera unit 1931; referring to fig. 4B, when detecting that the mobile phone 100 is in the folded state, the camera provider determines that the physical camera corresponding to the logical front camera identifier 1 is the camera unit 1932.
It can be appreciated that, in other embodiments, in the case where the logical camera to be started by the application is a logical post-camera (labeled 0), the camera provider may also determine that the physical camera corresponding to the logical camera label 0 is the camera unit 1933 when the mobile phone 100 is in the folded state; in the case that the mobile phone 100 is in the unfolded state, it is determined that the physical camera corresponding to the logical camera identifier 0 is the camera unit 1933 and/or the camera unit 1932, that is, in the case that the mobile phone 100 is in the unfolded state, the application program may collect an image or a video through the camera unit 1933 or the camera unit 1932, or may collect an image or a video through collaborative shooting by the camera unit 1933 and the camera unit 1932.
S503: and starting the determined physical camera.
That is, the camera provider starts the corresponding physical camera according to the physical camera identifier of the physical camera determined in step S502, and provides an interface for the application program to collect images or videos through the physical camera.
For example, in the scenario shown in fig. 4A, the camera provider may activate the camera unit 1931 and provide an interface for the camera application to capture images or video through the camera unit 1931; in the scenario illustrated in fig. 4B, the camera provider may activate the camera unit 1932 and provide an interface for camera applications to capture images or video via the camera unit 1932.
It will be appreciated that after the camera provider activates the corresponding physical camera and provides an interface through which the application program captures images or video, the application program may capture images or video through the physical camera.
It should be understood that the foregoing process of performing the steps S501 to S503 with the camera provider is only an example, and in other embodiments, the process may be performed by other applications/modules/services in the mobile phone 100, for example, application software at an application layer, services at an application framework layer, etc., which are not limited herein.
It should be understood that the foregoing execution sequence of steps S501 to S503 is only an example, and in other embodiments, other sequences may be adopted, and partial steps may be combined or split, which is not limited herein.
By the method provided by the embodiment of the application program, the application program in the mobile phone 100 can acquire images or videos through the corresponding physical cameras when the mobile phone 100 is in different forms through the same logical camera identification, and a developer of the application program does not need to integrate instructions for determining the physical cameras corresponding to the logical cameras according to the form of the mobile phone 100 in the application program, so that the development cost of the application program is reduced.
For easy understanding, a software architecture of the mobile phone 100 suitable for the photographing method provided in the embodiment of the present application is described below.
Specifically, fig. 6 illustrates a software architecture diagram of a mobile phone 100, according to some embodiments of the present application.
Referring to fig. 6, the software architecture of the mobile phone 100 includes an application layer 01, an application framework layer 02, a hardware abstraction layer 03, and a kernel layer 04, wherein:
the application layer 01 includes applications of the handset 100 such as cameras that can capture images or video through a camera of the handset 100 and/or third party applications 011. The camera and/or third party application 011 may facilitate access interfaces to physical cameras through the handset 100 by sending a request to activate a camera to a camera service 025 in the application framework layer 02, in some embodiments the camera and/or third party application 011 includes, but is not limited to, a camera application, instant messaging application, browser application, video conferencing application, and the like. As previously described, the request for starting the camera may include a logical camera identifier to be started, for example, a logical front camera identifier 1, a logical rear camera identifier 0, and the like.
It will be appreciated that in other implementations, where there is only one physical camera corresponding to the logical camera, the start-up camera request may also include a physical camera identifier, which is not limited herein.
It will be appreciated that in other embodiments, the application layer 01 may include further applications, such as "information," "calendar," "memo," etc., without limitation.
The application framework layer 02 provides an application programming interface (application programming interface, API) and programming framework for the application of the application layer 01 so that the application can interact with services/applications/modules/drivers in the hardware abstraction layer 03 and the kernel layer 04. In some embodiments, the application framework layer 02 may include:
the screen folding management (HwFoldScreenManager) 021 may obtain the form of the mobile phone 100 from the data of each Sensor acquired based on the Sensor Service 022, and send the form to the system Service management 023 so that each system Service or application may acquire the folded (screen) form of the mobile phone 100.
In some embodiments, the screen collapse manager 021 may send a notification of the change in the form of the mobile phone 100 to each service/module in the system service manager (SystemManager) 023 in the case where it is determined that the form of the mobile phone 100 changes, for example, in the case where it is determined that the mobile phone 100 is switched from an expanded state to a collapsed state, so that the system service/application may respond according to the notification. For example, upon receiving notification that the mobile phone 100 is switched from the unfolded state to the folded state, the camera provider 032 switches the physical camera corresponding to the logical front camera id 1 from the camera unit 1931 to the camera unit 1932.
The sensor service 022 is used to provide an interface for acquiring sensor data of the mobile phone 100 to an application/service in the mobile phone 100. In some embodiments, the Sensor services 022 may include a gesture Sensor service (Posture Sensor) 0221, a Hinge Sensor service (Hinge Sensor) 0222, and a Hall Sensor service (Hall Sensor) 0223. The attitude sensor service 0221 can acquire data of the gyroscope, and thereby determine the rotation angle of the mobile phone 100 from the data. The hinge sensor service 0222 can determine the form of the mobile phone 100, such as the folding angle, through the angle determination unit 031 and the hinge sensor drive 041. The hall sensor service 0223 may obtain hall sensor data of the cell phone 100 through the hall sensor driver 042, which in some embodiments may be used to determine the morphology of the cell phone 100.
It is understood that in other embodiments, the sensor service 022 may also include more or fewer sensor services, and is not limited herein.

It is understood that in other embodiments, system service 023 may include more or fewer services, and embodiments of the present application are not limited in this respect.
Post camera 024 is used to provide an interactive interface for the camera folding screen extension module 0232 and the hardware abstraction layer (Hardware Abstraction Layer, HAL) 03. For example, the camera post-processing 024 may receive the form of the handset 100 sent by the camera folding screen extension module and forward the form of the handset 100 to the camera provider 032 in the hardware abstraction layer 03 via the hardware abstraction layer interface definition language (HAL Interface Definition Language, HIDL).
The camera service 025 is configured to provide an interface to the application in the application layer 01 for accessing the camera provider 032, e.g., in some embodiments, the camera service 025 may forward the identity of the camera to be started, e.g., logical front camera identity 1, logical back camera identity 0, sent by the camera/third party application 011 to the camera service 025, to the camera provider 032.
It will be appreciated that in other embodiments, more or fewer modules may be included in the application framework layer 02, and embodiments of the present application are not limited thereto.
The hardware abstraction layer 03 is used to provide an access interface for hardware of the mobile phone 100 to the application framework layer 02 or the application layer 01. For example, in some embodiments, the hardware abstraction layer 03 may include an angle determination unit 031 and a camera provider 032. The angle determining unit 031 is used for determining the folding angle of the mobile phone 100 according to the data of the hinge sensor. The camera provider 032 is configured to determine a physical camera corresponding to the logical camera identifier according to the logical camera identifier or the physical camera identifier sent by the application program or the camera service 025 in the application layer 01, the form of the mobile phone 100 acquired from the camera post-processing 024, and the correspondence between each logical camera and each physical camera, and provide an access interface of the physical camera to the application layer 01.
It will be appreciated that in other embodiments, the hardware abstraction layer 03 may also include more modules, such as bluetooth, audio, and video, and the like, which are not limited herein.
The kernel layer 04 is configured to provide an access interface for hardware of the mobile phone 100 to the hardware abstraction layer 03, the application framework layer 02 and the application layer 01, so that the hardware abstraction layer 03, the application framework layer 02 and the application layer 01 can obtain data from the hardware of the mobile phone 100 or send data to the hardware of the mobile phone 100 through the interface. For example, in some embodiments, the kernel layer 04 may include a hinge sensor driver 041, a hall sensor driver 042, a camera unit 1931 driver 043, a camera unit 1932 driver 044, and a camera unit 1933 driver 045, each of which may be used to drive corresponding hardware so that applications/services/modules in the handset 100 may obtain data from or send data through the corresponding hardware. For example, the camera unit 1931 driver 043 may provide image data collected by the camera unit 1931 to the camera/third party application 011.
