[0035] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0036] In this embodiment, the terminal with a foldable screen can adapt to the current folded state or unfolded state according to the user's operation. For example, when the terminal with a foldable screen is in the unfolded state and the main screen is open, if the user folds the terminal with a foldable screen, the display content of the main screen will be transmitted and displayed on the folded screen. The terminal with a foldable screen can be a mobile phone, tablet computer, etc. with a foldable screen.

[0037] However, the current camera application is basically not adapted to the folding screen switching, and will not respond to the folding or unfolding events of the folding screen. It always uses the camera tag CameraID=1 to open the front camera. For example, if multiple front cameras are connected to the same CSI, CameraID=1 is still used to open the front camera. It is impossible to identify which camera is opened, and the data transmission of multiple cameras will conflict.

[0038] In view of this, the present disclosure provides a camera control method. When the camera application of a terminal with a folding screen is triggered to open, the target camera that matches the current state of the folding screen can be controlled to open. The problem of data transmission conflicts between multiple cameras is solved, and adaptive switching of multiple cameras is achieved, thereby improving the user's visual experience.

[0039] Figure 1 is a flow chart of a camera control method according to an exemplary embodiment, the camera control method is applied to a terminal with a folding screen, such as Figure 1 As shown, the method includes the following steps.

[0040] In step S11 , in response to a camera application in a terminal with a folding screen being triggered to open, a state of the folding screen and a state of the camera are determined.

[0041] In step S12, based on the state of the folding screen and the state of the camera, the target camera is controlled to turn on.

[0042] In the embodiment of the present disclosure, the camera application in the terminal with a foldable screen corresponds to multiple cameras, and the multiple cameras can use different CSI interfaces respectively, or share the same CSI interface. Among them, the CSI interface is used to transmit camera data.

[0043] In the disclosed embodiment, the state of the folding screen includes an unfolded state and a folded state, and the state of the camera includes an on state and a off state. The target camera is a camera corresponding to the state of the folding screen among the multiple cameras. It should be noted that different states of the folding screen correspond to different cameras among the multiple cameras.

[0044] According to the disclosed embodiment, when the camera application in the terminal with a folding screen is triggered to open, the matching target camera is controlled to open based on the current state of the folding screen and the state of the camera. This solution accurately determines the target camera of the camera application under different folding screen states, avoids data transmission conflicts between multiple cameras, realizes adaptive switching of multiple cameras, and improves the user experience.

[0045] In the present disclosure, based on the state of the folding screen and the state of the camera, the target camera is controlled to be turned on, including two situations, one of which is described below.

[0046] Figure 2 is a flow chart of another camera control method according to an exemplary embodiment. Figure 2 As shown, the method includes the following steps.

[0047] In step S21 , in response to determining that a camera application in a terminal with a folding screen is triggered to open, a state of the folding screen and a state of the camera are determined.

[0048] In step S22, if the state of the camera is off, the state of the current folding screen is determined, and the camera corresponding to the state of the current folding screen is controlled to turn on.

[0049] Taking the front camera of a terminal with a folding screen as an example, the label of the front inner screen camera can be set to 1, and the label of the front outer screen camera can be set to 2. When the camera application of the terminal with a folding screen opens the camera_ID=1 front camera instruction, the labels of the two physical cameras of the front camera with camera_ID=1 are obtained. Among them, the unfolded state of the folding screen corresponds to the camera with label 1, and the folded state of the folding screen corresponds to the camera with label 2. If there is no camera that has been opened when the front camera instruction to open camera_ID=1 is received and the folding screen of the current terminal is in the unfolded state, the physical camera with label 1 is opened. If there is no camera that has been opened when the front camera instruction to open camera_ID=1 is received and the folding screen of the current terminal is in the unfolded state, the physical camera with label 2 is opened.

[0050] In the embodiment of the present disclosure, the state of the camera is closed, which means that any camera is not turned on. If the current state of the folding screen is the unfolded state, the camera of the inner screen of the folding screen is controlled to be turned on. If the current state of the folding screen is the folded state, the camera of the outer screen of the folding screen is controlled to be turned on. It can be understood that when the folding screen is in the unfolded state, the camera of the inner screen of the folding screen is corresponding, and when the folding screen is in the folded state, the camera of the outer screen of the folding screen is corresponding.

[0051] According to the embodiment of the present disclosure, if any camera is in the off state, the corresponding target camera is controlled to be turned on based on the determined state of the folding screen. This method can directly and accurately identify the target camera that the user needs to turn on based on the state of the folding screen, so that the target camera matches the current state of the folding screen.

[0052] In the present disclosure, for controlling the target camera to turn on based on the state of the folding screen and the state of the camera, one scenario of the process has been described above, and another scenario will be described below.

[0053] Figure 3 is a flowchart of another camera control method according to an exemplary embodiment. Figure 3 As shown, the method includes the following steps.

[0054] In step S31 , in response to a camera application in a terminal with a folding screen being triggered to open, a state of the folding screen and a state of the camera are determined.

[0055] In step S32, if the state of the camera is on, the state change of the folding screen is determined.

[0056] In step S33, the target camera is determined according to the state change of the folding screen, and the target camera is controlled to be turned on.

[0057] Similarly, taking the front camera of a terminal with a folding screen as an example, the label of the front inner screen camera is set to 1, and the label of the front outer screen camera is set to 2. When the camera application of the terminal with a folding screen opens the camera_ID=1 front camera instruction, the labels of the two physical cameras of the front camera with camera_ID=1 are obtained. Among them, the unfolded state of the folding screen corresponds to the camera with label 1, and the folded state of the folding screen corresponds to the camera with label 2. If the camera currently exists and is turned on when the front camera instruction to open camera_ID=1 is received and matches the state of the folding screen of the current terminal, no processing is performed. If the camera currently exists and is turned on when the front camera instruction to open camera_ID=1 is received but does not match the state of the folding screen of the current terminal, the camera corresponding to the current label is cleared, and the camera with the label corresponding to the state of the current folding screen is configured and turned on.

[0058] In the embodiment of the present disclosure, the state of the camera is the on state, which means that at least one camera is in the on state. The state change of the folding screen includes: the state of the folding screen has not changed, or the state of the folding screen has changed.

[0059] According to the embodiment of the present disclosure, if at least one camera is turned on, a corresponding operation is performed according to whether the state of the folding screen has changed. This method can make the current camera still match the current state of the folding screen when the user has not changed the state of the folding screen, and make the current camera match the changed state of the folding screen when the user has changed the state of the folding screen. This realizes the adaptive switching of the camera and improves the user experience.

[0060] In the present disclosure, operations corresponding to different folding screen state changes are performed according to different folding screen state changes. If the folding screen state does not change, the target camera does not change.

[0061] Figure 4 is a flow chart of another camera control method according to an exemplary embodiment. Figure 4 As shown, the method includes the following steps.

[0062] In step S41 , in response to a camera application in a terminal with a folding screen being triggered to open, a state of the folding screen and a state of the camera are determined.

[0063] In step S42, if the camera is in the on state, the state change of the folding screen is determined.

[0064] In step S43, if the state of the folding screen has not changed, the camera that is currently in the turned-on state is determined as the target camera, and the turned-on state of the camera that is currently in the turned-on state is maintained.

[0065] For ease of understanding, the following examples are given. If the internal screen camera of the front camera in the terminal with a folding screen is currently turned on, and the folding screen of the current terminal remains in the unfolded state, no processing is performed. That is, it is equivalent to keeping the internal screen camera turned on. If the external screen camera of the front camera in the terminal with a folding screen is currently turned on, and the folding screen of the current terminal remains in the folded state, no processing is performed. That is, it is equivalent to keeping the external screen camera turned on.

[0066] According to the disclosed embodiment, through further real-time judgment, when the state of the folding screen has not changed, the current camera remains turned on. This method can reduce multiple judgments and multiple switching operations of the system, while keeping the current camera matching the state of the current folding screen in real time, saving system resources.

[0067] In the present disclosure, operations corresponding to different folding screen state changes are performed according to different folding screen state changes. If the state of the folding screen changes, the target camera is changed accordingly.

[0068] Figure 5is a flowchart of another camera control method according to an exemplary embodiment. Figure 5 As shown, the method includes the following steps.

[0069] In step S51 , in response to a camera application in a terminal with a folding screen being triggered to open, a state of the folding screen and a state of the camera are determined.

[0070] In step S52, if the camera is in the on state, the state change of the folding screen is determined.

[0071] In step S53, if the state of the folding screen changes, the camera corresponding to the state after the folding screen state changes is used as the target camera.

[0072] In step S54, the configuration resources of the camera corresponding to the state before the folding screen state changes are cleared, and the configuration resources of the target camera are initialized to turn off the camera that is currently on and control the target camera to turn on.

[0073] For ease of understanding, the following examples are given. If the internal screen camera of the front camera in the terminal with a folding screen has been turned on, and the state of the folding screen of the current terminal changes to a folded state, the internal screen camera is turned off, and the external screen camera is turned on. This is equivalent to switching from the internal screen camera to the external screen camera. If the external screen camera of the front camera in the terminal with a folding screen has been turned on, and the state of the folding screen of the current terminal changes to an unfolded state, the external screen camera is turned off, and the internal screen camera is turned on. This is equivalent to switching from the external screen camera to the internal screen camera.

[0074] In the disclosed embodiment, since multiple cameras may be connected to the same CSI interface, and one CSI interface cannot transmit data from multiple cameras at the same time. Therefore, when the state of the folding screen changes, the camera resources need to be reconfigured. Specifically: clear the configuration resources of the camera corresponding to the state before the folding screen state changes, and initialize the configuration resources of the target camera. Reconfiguration can transmit the data of the target camera, and then control the target camera to turn on.

[0075] According to the embodiment of the present disclosure, the currently turned on camera is turned off and the target camera is turned on by reconfiguring when the state of the folding screen changes. This process can realize resource configuration for the camera that is turned on, and can accurately turn on and configure the target camera based on the mapping relationship between the state of the folding screen and the camera, avoiding conflicts in data transmission between multiple cameras.

[0076] In the present disclosure, since there may be a phenomenon of residual preview images during the camera switching process, in order to optimize the user's visual experience, blur processing is further used to process the residual images during the switching process.

[0077] Figure 6 is a flow chart of a method for optimizing camera control according to an exemplary embodiment. Figure 6 As shown, the method includes the following steps.

[0078] In step S61, the camera that is currently turned on is turned off.

[0079] In step S62, blur processing is performed on the blurred image displayed in the camera application.

[0080] In step S63, the target camera is controlled to be turned on.

[0081] In the embodiment of the present disclosure, the blurred image displayed in the camera application is a residual preview image captured by the closed camera. The blurring process adopts Gaussian blurring process.

[0082] According to the disclosed embodiment, the camera switching process in the disclosed camera control method is optimized. Gaussian blur processing is performed during the camera switching process, so that the image can be switched smoothly, avoiding the influence of the residual image on the new image, and improving the user's visual experience.

[0083] In the present disclosure, the above-mentioned camera control method is generally described by taking the front camera application as an example.

[0084] Figure 7 is a flow chart of another camera control method according to an exemplary embodiment. Figure 7 As shown, the method includes the following steps.

[0085] In step S101, the front camera is turned on. It should be noted that the front camera is turned on for the first time, that is, the current state of the camera is turned off.

[0086] In step S102, the current state of the folding screen is determined. If the current state of the folding screen is in the unfolded state, step S103 is executed. If the current state of the folding screen is in the folded state, step S104 is executed.

[0087] In step S103, a first camera is turned on. The first camera is a camera corresponding to the inner screen of the terminal with a foldable screen.

[0088] In step S104, the second camera is turned on. The second camera is a camera corresponding to the external screen of the terminal with a foldable screen.

[0089] In step S105, the current camera is in the open state, and it is further determined whether the state of the folding screen has changed. If the state of the folding screen has not changed, step S106 is executed. If the state of the folding screen has changed, step S107 is further executed.

[0090] In step S106, if the state of the folding screen has not changed, no processing is performed.

[0091] In step S107, when the state of the folding screen changes, it is further determined how the state of the folding screen changes. If the folding state of the folding screen changes from the unfolded state to the folded state, step S108 is executed. If the folding state of the folding screen changes from the folded state to the unfolded state, step S109 is executed.

[0092] In step S108, the first camera is turned off and the second camera is turned on.

[0093] In step S109, the second camera is turned off and the first camera is turned on.

[0094] In step S110, the front camera operates normally.

[0095] In the embodiment of the present disclosure, there is a preset mapping relationship between the state of the folding screen and the physical camera. The mapping relationship includes: the folded state of the folding screen corresponds to the camera corresponding to the inner screen of the terminal with the folding screen, and the unfolded state of the folding screen corresponds to the camera corresponding to the outer screen of the terminal with the folding screen. That is, in the embodiment of the present disclosure, the folded state of the folding screen corresponds to the first camera, and the unfolded state of the folding screen corresponds to the second camera.

[0096] For ease of understanding, the following provides examples with reference to diagrams. Figure 8 is an exemplary diagram of a terminal with a folding screen in an unfolded state according to an exemplary embodiment. Figure 8 As shown, the unfolded state corresponds to camera 1, and camera 1 represents the front camera of the terminal inner screen. Fig. 9 is an exemplary diagram of a terminal with a folding screen in a folded state according to an exemplary embodiment. Fig. 9As shown, the folded state corresponds to camera 2, and camera 2 represents the front camera of the terminal's external screen. In the following examples, camera 1 is represented by front1, camera 2 is represented by front2, fold indicates that the folding screen of the folding screen terminal is in the folded state, and unfold indicates that the folding screen of the terminal is in the unfolded state. When we open the front camera while using a terminal with a folding screen, the system will obtain the state of the folding screen of the current terminal. If the state of the folding screen is unfolded, perform the initial configuration of front1, and after the configuration is completed, front1 can be opened, which is equivalent to opening the corresponding front1 in the unfolded state when the folding screen is in the unfolded state. If the state of the folding screen is folded, perform the configuration of front2, and after the configuration is completed, front2 can be opened, which is equivalent to opening the corresponding front2 in the folded state when the folding screen is in the folded state.

[0097] Further, based on the fact that the current camera is already in the open state, if the state of the folding screen has not changed, no processing is performed, and the current camera remains in the open state. Specifically, if the current state of the folding screen is the unfolded state, the open state of front1 is maintained. If the state of the folding screen is the folded state, the open state of front2 is maintained. If the state of the folding screen changes, reconfiguration is required to achieve camera switching. Specifically, if the state of the folding screen changes from the unfolded state to the folded state, the configuration information of the corresponding front1 in the current unfolded state is cleared, and the corresponding front2 configuration in the folded state is re-performed, thereby achieving the closing of front1 and the opening of front2, which is equivalent to the switching from front1 to front2. If the folding state of the folding screen changes from the folded state to the unfolded state, the configuration information of the corresponding front2 in the current folded state is cleared, and the corresponding front1 configuration in the unfolded state is re-performed, thereby achieving the closing of front2 and the opening of front1, which is equivalent to the switching from front2 to front1. The above process enables the opened front camera to operate normally.

[0098] In the disclosed embodiment, through the mapping relationship between the folding screen state and the physical camera, the current camera is turned off in time and the target camera is turned on, thereby realizing the adaptive switching of the front multi-camera. This solution can be applied to the scene where multiple front cameras share the same CSI interface, and the scene where multiple front cameras use different CSI interfaces, and has good versatility.

[0099] In the present disclosure, the camera needs to be configured whether it is turned off or on. The overall configuration method in the above solution is specifically described below.

[0100] Fig.10 is a flowchart of a camera configuration method according to an exemplary embodiment. Fig.10 As shown, the method includes the following steps.

[0101] In step S201, the front camera is turned on.

[0102] In step S202, the HAL layer is initially configured.

[0103] It should be noted that the HAL (HardwareAbstractionLayer) layer is the hardware abstraction layer. The role of HAL is to represent the rest of the operating system as an abstract hardware device. The initial configuration process executes the configure_streams(...) method, where the configure_streams process refers to configuring the camera's data stream output. Specifically, the configure_streams process includes determining the type of data to be output, setting parameters such as the resolution and frame rate of the data stream, configuring the format and encoding method of the data stream, determining the transmission method of the data stream, and testing the stability and quality of the data stream to ensure the accuracy and reliability of the output data. In general, when performing the configure_streams configuration process, a single physical camera needs to correspond to one CSI interface.

[0104] In step S203, it is determined whether the state of the folding screen has changed. If the state of the folding screen has not changed, step S204 is executed. If the state of the folding screen has changed, step S205 is executed.

[0105] In step S204, the HAL layer does not perform any processing.

[0106] In step S205, the HAL layer is reconfigured.

[0107] It should be noted that the reconfiguration of the HAL layer includes: flushing the front camera that is currently in the open state, releasing the physical camera and its CSIPHY and other resources in the process. init the physical front camera and its CSIPHY resources corresponding to the folded state of the folding screen of the terminal with a folding screen. Among them, flush is the refresh method, and init is the initialization method. CSIPHY and other resources are the resources configured by the configure_streams(...) method executed by the above-mentioned HAL layer. This process control realizes the reasonable allocation of the CSI interface during the camera configuration process.

[0108] In step S206, the front camera operates normally.

[0109] According to the disclosed embodiment, it is possible to determine whether reconfiguration is required based on the state of the folding screen. The method can configure the corresponding camera when the state of the folding screen changes, implement the configuration switching of the two physical cameras at the bottom layer, and then enable the camera application to control the opening of the target camera. The adaptive switching of the business layer camera is achieved through the configuration of the bottom layer logic, which improves the user experience.

[0110] Based on the same concept, an embodiment of the present disclosure also provides a camera control device.

[0111] It is understandable that the camera control device provided in the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.
