[0002] Currently, many third-party applications on electronic devices have shooting functions. When using these third-party applications to take photos, the rear main camera is usually used. Since the rear main camera has a specific field of view (FOV) and focal length, when the zoom ratio or object distance changes, the photo may not be clear or the preview effect may be poor. Summary of the invention

[0003] The embodiments of the present application provide an image processing method, an electronic device, and a computer-readable storage medium, which are intended to solve the problem of poor shooting effects of three-party applications when the zoom ratio or object distance changes.

[0004] According to a first aspect of an embodiment of the present application, there is provided an image processing method, which is applied to an electronic device, and the method comprises: starting a shooting function based on a third-party application, and displaying a first preview image on a camera preview interface of the third-party application. The first preview image is associated with a first physical camera, and the zoom ratio corresponding to the first preview image is a first zoom ratio. In response to a zoom operation and / or a change in the distance between the electronic device and the photographed object, a second preview image is displayed on the camera preview interface. The second preview image is associated with a second physical camera, and the zoom ratio corresponding to the second preview image is a second zoom ratio, and the second physical camera is different from the first physical camera.

[0005] In this embodiment, since the logical cameras supported by the third-party application include multiple physical cameras, such as a wide-angle camera, an ultra-wide-angle camera, and a telephoto camera, and multi-camera switching permissions are open to the third-party application, when the zoom ratio or the distance between the electronic device and the subject changes, it can switch to a different physical camera accordingly, thereby improving the photo performance and shooting effect of the third-party application.

[0006] In one embodiment, in response to a zoom operation and / or a change in the distance between the electronic device and the subject, a second preview image is displayed on the camera preview interface, including: based on the first physical camera being a wide-angle camera, in response to the zoom operation, the second zoom ratio is less than the first zoom ratio, and the second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is an ultra-wide-angle camera.

[0007] In another embodiment, in response to a zoom operation and / or a change in the distance between the electronic device and the subject, a second preview image is displayed on the camera preview interface, including: based on the first physical camera being a wide-angle camera, in response to the zoom operation, the second zoom ratio is greater than the first zoom ratio, and the second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is a telephoto camera.

[0008] In another embodiment, in response to a zoom operation and / or a change in the distance between the electronic device and the subject, a second preview image is displayed on the camera preview interface, including: based on the first physical camera being a wide-angle camera, in response to the distance between the electronic device and the subject being less than a distance threshold, the second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is an ultra-wide-angle camera.

[0009] In another embodiment, in response to a zoom operation and / or a change in the distance between the electronic device and the subject, a second preview image is displayed on the camera preview interface, including: based on the first physical camera being an ultra-wide-angle camera, in response to the zoom operation, the second zoom ratio is greater than the first zoom ratio, and the second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is a wide-angle camera or a telephoto camera.

[0010] Specifically, based on the second zoom ratio being equal to 1X, the second physical camera is a wide-angle camera. Based on the second zoom ratio being greater than 1X, the second physical camera is a telephoto camera.

[0011] In another embodiment, in response to a zoom operation and / or a change in the distance between the electronic device and the subject, a second preview image is displayed on the camera preview interface, including: based on the first physical camera being an ultra-wide-angle camera, in response to the distance between the electronic device and the subject being greater than or equal to a distance threshold, the second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is a wide-angle camera.

[0012] In another embodiment, in response to a zoom operation and / or a change in the distance between the electronic device and the subject, a second preview image is displayed on the camera preview interface, including: based on the first physical camera being a telephoto camera, in response to the zoom operation, the second zoom ratio is less than the first zoom ratio, and the second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is a wide-angle camera or an ultra-wide-angle camera.

[0013] In another embodiment, the method further includes: based on the third-party application turning off the shooting function and the system camera application starting the shooting function, displaying a third preview image on the preview interface of the system camera application. The third preview image is associated with the first physical camera, and the zoom ratio corresponding to the third preview image is a third zoom ratio. In response to the zoom operation and / or the change in the distance between the electronic device and the photographed object, displaying a fourth preview image on the preview interface. The fourth preview image is associated with the second physical camera, and the zoom ratio corresponding to the fourth preview image is a fourth zoom ratio.

[0014] In this embodiment, in the scenario where the third-party application turns off the shooting function and the system camera application starts the shooting function, since the logical cameras supported by the system camera application include multiple physical cameras, such as a wide-angle camera, an ultra-wide-angle camera, and a telephoto camera, and multi-camera switching permissions are open to the system camera application, when the zoom ratio or the distance between the electronic device and the subject changes, it can switch to a different physical camera accordingly, thereby improving the system camera application's photo performance and shooting effects.

[0015] In another embodiment, the method further includes: based on the third-party application turning off the shooting function and the system camera application starting the shooting function, displaying a fifth preview image on the preview interface of the system camera application. The fifth preview image is associated with the first physical camera, and the zoom ratio corresponding to the fifth preview image is a fifth zoom ratio. In response to the zoom operation and / or the change in the distance between the electronic device and the photographed object, the fifth preview image is displayed on the preview interface.

[0016] In this embodiment, in the scenario where the third-party application turns off the shooting function and the system camera application starts the shooting function, since the original logical camera that supports the separate physical camera is the logical camera called by default by the third-party application, and the physical camera configuration of the logical camera called by default by the third-party application is modified, a new logical camera that supports the separate physical camera is added, so that the system camera application can use the separate physical camera to take pictures by calling the newly added logical camera.

[0030] It should be noted that in the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more than two. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The terms "first", "second", etc. in the specification, claims and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0031] It should also be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchangeable with each other, and some of the steps can also be deleted.

[0032] The electronic devices of the embodiments of the present application may include smart phones with shooting functions, tablet computers, PDAs, laptop computers, mobile Internet devices (MID), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control (Industrial Control), wireless terminals in self-driving (Self Driving), wireless terminals in remote medical surgery (Remote Medical Surgery), wireless terminals in smart grids (Smart Grid), wireless terminals in transportation safety (Transportation Safety), wireless terminals in smart cities (Smart City), wireless terminals in smart homes (Smart Home), cellular phones, cordless phones, Session Initiation Protocol (Session Initiation Protocol, SIP) phones, Wireless Local Loop (Wireless Local Loop, WLL) stations, Personal Digital Assistants (Personal Digital Assistant, PDA), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5G networks or public land mobile communication networks (Public Land Mobile Terminal equipment in Network, PLMN, etc.

[0033] To meet the user's shooting needs, the electronic device may include multiple physical cameras, such as a wide-angle (Wide) camera, an ultra-wide-angle (Ultrawide, UW) camera, a telephoto (Tele) camera, etc. Each physical camera has a corresponding field of view (Field of View, FOV) and focal length. For example, when using an electronic device to shoot a distant object, the zoom ratio can be enlarged to bring the distance between the electronic device and the object closer. Based on different zoom ratios and different object distances, using physical cameras with different focal lengths to take pictures / records can obtain a higher-definition picture. During the zoom process, when a certain zoom ratio is reached, the electronic device will switch to a different physical camera. For example, in the process of the zoom ratio increasing from the minimum value, the electronic device will use an ultra-wide-angle camera, a wide-angle camera, and a telephoto camera in turn.

[0034] To achieve different shooting modes, the electronic device may include multiple logical cameras, and the logical camera may include at least one physical camera. Different logical cameras have corresponding camera identifications (CameraIdentification, CameraID). The CameraID corresponding to the logical camera can be customized by the electronic device manufacturer. Exemplarily, the logical camera with CameraID 0 includes a rear main camera (referred to as rear main camera), and the rear main camera is usually a wide-angle camera. The logical camera with CameraID 5 includes a rear main camera, a rear ultra-wide-angle camera (referred to as rear ultra-wide) and a rear telephoto camera (referred to as rear telephoto).

[0035] Currently, many third-party applications on electronic devices have shooting functions. When using these third-party applications to take photos, the rear main camera is usually used to take photos. Since the rear main camera has a specific FOV and focal length, when the zoom ratio or object distance changes, the photo may not be clear or the preview effect may be poor. For example, Figure 1 As shown, when using a third-party application to take pictures, the third-party application will call the logical camera with CameraID 0, that is, use the rear main camera to take pictures. When using the system camera application to take pictures, the system camera application can call the logical camera with CameraID 0, that is, use the rear main camera alone to take pictures. The system camera application can also call the logical camera with CameraID 5, and enable the multi-camera processing engine for camera switching, that is, support the use of any of the rear main camera, rear ultra-wide and rear telephoto cameras to take pictures. Therefore, compared with the system camera application, due to the limitations of third-party application photography, the output effect is not good in some scenarios, such as unclear close-up photos, or poor preview of long-distance zoom.

[0036] Based on this, the embodiments of the present application provide an image processing method, an electronic device, and a computer-readable storage medium, which aim to solve the problem of poor shooting effects of three-party applications when the zoom ratio or object distance changes.

[0037] The image processing method of the embodiment of the present application is described in detail below in conjunction with the software structure of the electronic device.

[0038] Figure 2 It is a schematic diagram of the software structure of an electronic device provided in one embodiment of the present application.

[0039] The software system of electronic equipment can adopt a layered architecture, which divides the software into several layers. Each layer has a clear role and division of labor, and the layers communicate with each other through software interfaces. Figure 2 As shown, the software system of the electronic device is divided into three layers, from top to bottom, namely, the application (Application, APP) layer, the framework (Framework, FWK) layer and the hardware abstraction layer (HAL).

[0040] The application layer includes a series of application packages, which can include system applications and third-party applications.

[0041] The framework layer provides application programming interfaces (API) and programming frameworks for various apps in the application layer. The framework layer includes the camera framework (CameraFWK), which provides the camera API (CameraAPI) for third-party applications.

[0042] The camera framework may include a scene recognition module, which is used to identify third-party applications that request to start the camera. The scene recognition module can establish a whitelist by identifying third-party applications. The whitelist is used to store application identifiers that support multi-camera calls and switching. The application identifier may include the package name or signature of the application, etc.

[0043] In some embodiments, the scene recognition module is further used to determine whether the third-party application is an application in the white list. If the third-party application is an application in the white list, the third-party application is allowed to call multiple cameras. If the third-party application is not an application in the white list, the third-party application is prohibited from calling multiple cameras.

[0044] After the scene recognition module identifies the third-party application, the camera framework obtains the camera capabilities from the camera configuration file. The camera capabilities include the relevant configuration information of each logical camera, such as the CameraID corresponding to each logical camera and the physical camera configuration.

[0045] It is understood that the camera configuration file is a file pre-configured in the system. The camera configuration file is used to store camera capabilities. For example, Figure 3 As shown in the figure, since third-party applications call the logical camera with CameraID 0 by default, in the camera configuration file, the physical camera configuration of the logical camera with CameraID 0 can be modified from supporting the rear main camera to supporting the rear main camera, rear ultra-wide camera, and rear telephoto camera, and the multi-camera switching permission can be opened to third-party applications, that is, the multi-camera processing engine can switch the camera of the logical camera with CameraID 0, so that third-party applications can support the use of any of the rear main camera, rear ultra-wide camera, and rear telephoto camera to take pictures, thereby improving the photo performance and shooting effect of third-party applications. The system camera application can call the logical camera with CameraID 5 and enable the multi-camera processing engine to switch the camera. In some scenarios, the system camera application needs to use the rear main camera alone to take pictures. Since the original support for the rear main camera is the logical camera with CameraID 0, and the physical camera configuration of the logical camera with CameraID 0 has been modified, a new logical camera that supports the rear main camera is added, for example, the logical camera with CameraID 8. This allows the system camera application to use the rear main camera alone to take pictures by calling the logical camera with CameraID 8.

[0046] The hardware abstraction layer is used to execute the functional applications and data processing of various apps. The hardware abstraction layer includes the camera hardware abstraction layer (CameraHAL), which is used to implement multi-camera calling and switching.

[0047] Specifically, the camera hardware abstraction layer includes a camera startup module, a camera call module, a class object creation module, a customized extension module, an enabling module, a multi-camera capability management module, a multi-camera decision engine, a pipeline, and a multi-camera processing engine.

[0048] The camera startup module generates a camera call request corresponding to the third-party application based on the camera capabilities from the camera framework, and sends the camera call request to the camera call module. The camera call request includes the CameraID corresponding to the target logical camera, and the camera call request is used to request to call the target logical camera. The target logical camera is a logical camera supported by the third-party application, such as a logical camera with a CameraID of 0.

[0049] After receiving the camera call request, the camera call module calls the target logical camera and sends a camera call response to the camera start module. The camera call response includes the call result of the target logical camera, and the camera call response is used to indicate whether the call of the target logical camera is successful or failed.

[0050] The camera startup module starts the target logical camera based on the successful call of the target logical camera, and sends a class object creation instruction to the class object creation module. The class object creation instruction is used to instruct the creation of a class object corresponding to the target logical camera.

[0051] After receiving the class object creation instruction, the class object creation module creates a target class object (such as HALDevice) corresponding to the target logical camera, and sends relevant information of the target class object to the customized extension module. The relevant information of the target class object may include the class name, class variables and class methods of the target class object.

[0052] The customized extension module is a function application integration module customized by each electronic device manufacturer. After receiving the relevant information of the target class object, the customized extension module sends a multi-camera switching request corresponding to the target class object to the enabling module. The multi-camera switching request is used to request multi-camera switching permission.

[0053] After receiving the multi-camera switching request, the enabling module enables or disables the multi-camera switching function, fills the flag bit, and sends the flag bit value to the customized extension module. The flag bit value is used to indicate whether the multi-camera switching permission is open. Exemplarily, the flag bit value may include 1 or 0. The flag bit value of 1 indicates that the multi-camera switching permission is open, that is, the multi-camera switching function is enabled. The flag bit value of 0 indicates that the multi-camera switching permission is prohibited, that is, the multi-camera switching function is prohibited.

[0054] The customized extension module can determine whether the enabling module has opened the multi-camera switching permission based on the value of the flag bit. The customized extension module creates a session based on the determination that the enabling module has opened the multi-camera switching permission, and sends a multi-camera management request to the multi-camera capability management module. The multi-camera management request is used to request the management of multi-camera capabilities.

[0055] The multi-camera capability management module sends a multi-camera management instruction to the multi-camera decision engine based on the multi-camera management request. The multi-camera management instruction is used to start the multi-camera decision engine.

[0056] The multi-camera decision engine includes a multi-camera strategy initialization module, a multi-camera strategy selection module, and a multi-camera strategy output module. Among them, the multi-camera strategy initialization module is used to obtain the initialization configuration of multi-camera switching from the initialization configuration file, and perform multi-camera strategy initialization according to the initialization configuration. The multi-camera strategy selection module is used to obtain the decision configuration of multi-camera switching from the decision configuration file, and perform multi-camera strategy selection according to the decision configuration. The multi-camera strategy selection is based on the current zoom magnification to select the corresponding target physical camera. The multi-camera strategy output module outputs the multi-camera strategy to the Pipeline based on the multi-camera strategy selection result. The multi-camera strategy includes a channel flag corresponding to the target physical camera, which is used to select the real-time processing channel corresponding to the target physical camera. The real-time processing channel is used to perform real-time processing on the image collected by the sensor (Sensor), and the sensor includes each physical camera. Exemplarily, the channel flag may include 1 to 3. A channel flag of 1 indicates a real-time processing channel corresponding to the telephoto camera, a channel flag of 2 indicates a real-time processing channel corresponding to the ultra-wide-angle camera, and a channel flag of 3 indicates a real-time processing channel corresponding to the wide-angle camera.

[0057] It can be understood that both the initialization configuration file and the decision configuration file are pre-configured files in the system. The initialization configuration file includes the initialization configuration of multi-camera switching, and the initialization configuration may include the physical camera configuration supported by the third-party application and the value range of the zoom ratio. For example, the value range of the zoom ratio is greater than or equal to 0.1X and less than or equal to 50X. The decision configuration file includes the decision configuration of multi-camera switching, and the decision configuration may include the zoom ratio corresponding to each physical camera. For example, the zoom ratio corresponding to the ultra-wide-angle camera is greater than or equal to 0.1X and less than 1X, the zoom ratio corresponding to the wide-angle camera is 1X, and the zoom ratio corresponding to the telephoto camera is greater than 1X and less than or equal to 50X.

[0058] The pipeline includes a real-time processing path and a post-processing path corresponding to each physical camera. The pipeline selects the real-time processing path corresponding to the target physical camera based on the multi-camera strategy from the multi-camera strategy output module. The real-time processing path includes a sensor node, an image signal processing front end (Image singnal processing Front End, IFE) module and a statistical module. Among them, the sensor node can be a sensor-oriented control node, which is used to control the sensor through the sensor driver, such as controlling the target physical camera to collect images. After obtaining the original image collected by the sensor, the sensor node sends the original image to the IFE module. The IFE module is used to obtain statistical data from the original image, send the statistical data to the statistical module, and perform preliminary cropping processing on the original image, reserve the image edge (margin), so as to obtain the original image format (Raw Image Format, RAW) image, and send the RAW image to the post-processing path. After receiving the statistical data, the statistical module sends the statistical data to the multi-camera processing engine.

[0059] In some embodiments, the IFE module may also obtain statistical data from the RAW images.

[0060] It can be understood that the statistical data may include 3A statistical information, and the 3A statistical information includes automatic exposure (AutomaticExposure, AE) parameters, automatic focus (AutomaticFocus, AF) parameters and automatic white balance (Auto WhiteBalance, AWB) parameters.

[0061] The post-processing path includes a multi-camera module and an image signal processing post end (IPE) module. After receiving the RAW image from the IFE module, the multi-camera module sends the RAW image to the multi-camera processing engine, receives the transformed image from the multi-camera processing engine, and sends the transformed image to the IPE module. The IPE module is used to crop and warp the transformed image to obtain a preview image, and send the preview image to the camera framework. After receiving the preview image, the camera framework sends the preview image to the third-party application. After receiving the preview image, the third-party application displays the preview image on the camera preview interface.

[0062] It is understood that in other embodiments, the IFE module may perform more processing on the original image, such as color processing, denoising, enhancement, sharpening, etc. The IPE module may perform more processing on the transformed image, such as white balance, color correction, denoising, sharpening, exposure control, autofocus, etc. The preview image output by the IPE module may include the Joint Photographic Experts Group (JPEG) format or other image formats.

[0063] The multi-camera processing engine includes a first processing module, a second processing module and a perception engine. Among them, the first processing module includes a first front-end module, an algorithm processing module and a first back-end module. The first front-end module is used to receive statistical data from the statistical module and send the statistical data to the algorithm processing module. After receiving the statistical data, the algorithm processing module performs various algorithm processing on the statistical data by calling the perception engine, and sends the algorithm processing results to the first back-end module. After receiving the algorithm processing results, the first back-end module caches the algorithm processing results. The multi-camera processing engine sends a camera switching instruction to the Pipeline based on the algorithm processing results to switch the camera. The camera switching instruction is used to indicate switching to the camera selected by the algorithm. After receiving the camera switching instruction, the Pipeline switches to the real-time processing path corresponding to the camera selected by the algorithm.

[0064] The perception engine is used to execute various algorithms, thereby assisting the algorithm processing module to implement corresponding algorithm functions.

[0065] Exemplarily, the algorithm processing module calls the perception engine, and the perception engine identifies the distance between the target physical camera and the photographed object (i.e., the object distance) by executing the distance recognition algorithm. The algorithm processing module determines whether to switch the camera and which camera to switch to based on the object distance. Taking the target physical camera as a wide-angle camera as an example, since the wide-angle camera may not take clear photos when shooting close objects. Therefore, when the object distance is less than the distance threshold, the algorithm processing module determines to switch the wide-angle camera to an ultra-wide-angle camera to improve the close-up shooting effect.

[0066] The second processing module includes a second front-end module, a multi-camera switching module and a second back-end module. The second front-end module is used to receive the RAW image from the multi-camera module and send the RAW image to the multi-camera switching module. After receiving the RAW image, the multi-camera switching module spatially aligns the RAW image according to the spatial alignment transform (Spatial Alignment Transform, SAT) algorithm to obtain a transformed image, and sends the transformed image to the second back-end module. After receiving the transformed image, the second back-end module sends the transformed image to the multi-camera module. After being processed by the second processing module, the camera switching can be made smoother, thereby reducing the sense of disharmony of the picture before and after the camera switching.

[0067] Understandably, Figure 2 The layers in the software structure shown and the components contained in each layer do not constitute a specific limitation on the electronic device. In other embodiments, the electronic device may include more or fewer layers than shown, and each layer may include more or fewer components, which is not limited in the embodiments of the present application.

[0068] The image processing method of the embodiment of the present application is described in detail below in combination with scenes one to three.

[0069] For example, taking the current physical camera used by the third-party application as a wide-angle camera, the zoom ratio corresponding to the wide-angle camera is 1X.

[0070] Scenario 1: The zoom ratio changes from 1X to 0.5X.

[0071] Scenario 2: The zoom ratio changes from 1X to 3X.

[0072] Scenario 3: The object distance changes from 0.5m to 0.1m.

[0073] In the following scenario, the electronic device adjusts the zoom ratio from 1X to 0.5X in response to the zoom operation. The multi-camera decision engine performs multi-camera strategy selection through the multi-camera strategy selection module based on the change in zoom ratio from 1X to 0.5X, and outputs the multi-camera strategy to the Pipeline through the multi-camera strategy output module. At this time, the multi-camera strategy includes the channel flag corresponding to the ultra-wide-angle camera. The Pipeline selects the real-time processing channel corresponding to the ultra-wide-angle camera based on the multi-camera strategy from the multi-camera strategy output module.

[0074] The real-time processing path first obtains the original image collected by the sensor through the sensor node. Then, the IFE module obtains statistical data from the original image, sends the statistical data to the statistical module, and performs preliminary cropping processing on the original image to obtain a RAW image, and sends the RAW image to the post-processing path. Then, the real-time processing path sends the statistical data to the multi-camera processing engine through the statistical module. The multi-camera processing engine performs various algorithm processing on the statistical data through the algorithm processing module, such as using the distance recognition algorithm to identify the object distance. Based on the unchanged object distance, the multi-camera processing engine will not send a camera switching instruction to the Pipeline. Then, the post-processing path sends the RAW image to the multi-camera processing engine through the multi-camera module. The multi-camera processing engine performs SAT algorithm processing on the RAW image through the multi-camera switching module to obtain a transformed image. The multi-camera processing engine then sends the transformed image to the multi-camera module. Then, the multi-camera module sends the transformed image to the IPE module. The IPE module crops and distorts the transformed image to obtain a preview image, and sends the preview image to the camera framework. The camera framework then sends the preview image to the third-party application. Then, the third-party application displays the preview image on the camera preview interface.

[0075] It can be understood that the zoom operation may include an operation of clicking a zoom control, an operation of sliding a zoom control, and an operation of sliding a two-finger interface. The operation of sliding a two-finger interface may include a sliding operation of bringing two fingers together and a sliding operation of separating two fingers.

[0076] like Figure 4A and Figure 4B As shown, since the zoom ratio changes from 1X to 0.5X, the physical camera used by the third-party application switches from a wide-angle camera to an ultra-wide-angle camera, so that the FOV of the camera preview interface of the third-party application becomes significantly larger.

[0077] In scenario 2, the electronic device adjusts the zoom ratio from 1X to 3X in response to the zoom operation. Based on the change in zoom ratio from 1X to 3X, the multi-camera decision engine performs multi-camera strategy selection through the multi-camera strategy selection module, and outputs the multi-camera strategy to the Pipeline through the multi-camera strategy output module. At this time, the multi-camera strategy includes the channel flag corresponding to the telephoto camera. The Pipeline selects the real-time processing channel corresponding to the telephoto camera based on the multi-camera strategy from the multi-camera strategy output module.

[0078] It can be understood that after the Pipeline selects the real-time processing path, the image processing process of scene 2 is roughly the same as that of scene 1, and will not be repeated here.

[0079] like Figure 4A and Figure 4CAs shown, since the zoom ratio changes from 1X to 3X, the physical camera used by the third-party application switches from a wide-angle camera to a telephoto camera, so that the FOV of the camera preview interface of the third-party application becomes significantly smaller.

[0080] In scenario three, the object distance changes from 0.5m to 0.1m based on the electronic device approaching the subject. The multi-camera processing engine uses the distance recognition algorithm to identify the object distance, and sends a camera switching instruction to the Pipeline based on the object distance changing from 0.5m to 0.1m. At this time, the camera switching instruction indicates to switch to the ultra-wide-angle camera. Then, the Pipeline switches to the real-time processing path corresponding to the ultra-wide-angle camera according to the camera switching instruction.

[0081] It can be understood that after Pipeline selects the real-time processing path, the image processing process of scene three is roughly the same as that of scene one / scene two, and will not be repeated here.

[0082] like Figure 5A and Figure 5B As shown, since the object distance changes from 0.5m to 0.1m, the physical camera used by the third-party application switches from a wide-angle camera to an ultra-wide-angle camera, so that the FOV of the camera preview interface of the third-party application becomes significantly larger.

[0083] Figure 6 It is a flowchart of an image processing method provided by an embodiment of the present application.

[0084] Image processing methods are applied to electronic devices, such as Figure 6 As shown, the image processing method comprises the following steps:

[0085] S101, starting a shooting function based on a third-party application, and displaying a first preview image on a camera preview interface of the third-party application.

[0086] The first preview image is associated with the first physical camera, and the zoom ratio corresponding to the first preview image is the first zoom ratio.

[0087] S102: In response to a zoom operation and / or a change in the distance between the electronic device and the photographed object, display a second preview image on the camera preview interface of the third-party application.

[0088] The second preview image is associated with a second physical camera, and the zoom ratio corresponding to the second preview image is a second zoom ratio. The second physical camera is different from the first physical camera.

[0089] In one embodiment, step S102 includes: based on the first physical camera being a wide-angle camera, in response to a zoom operation, the second zoom ratio is less than the first zoom ratio, a second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is an ultra-wide-angle camera.

[0090] In another embodiment, step S102 includes: based on the first physical camera being a wide-angle camera, in response to a zoom operation, the second zoom ratio is greater than the first zoom ratio, a second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is a telephoto camera.

[0091] In another embodiment, step S102 includes: based on the first physical camera being a wide-angle camera, in response to the distance between the electronic device and the photographed object being less than a distance threshold, displaying a second preview image on the camera preview interface, and the second physical camera corresponding to the second preview image is an ultra-wide-angle camera.

[0092] In another embodiment, step S102 includes: based on the first physical camera being an ultra-wide-angle camera, in response to a zoom operation, the second zoom ratio is greater than the first zoom ratio, a second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is a wide-angle camera or a telephoto camera.

[0093] Specifically, when the second zoom ratio is equal to 1X, the second physical camera is a wide-angle camera. When the second zoom ratio is greater than 1X, the second physical camera is a telephoto camera.

[0094] In another embodiment, step S102 includes: based on the first physical camera being an ultra-wide-angle camera, in response to the distance between the electronic device and the photographed object being greater than or equal to a distance threshold, displaying a second preview image on the camera preview interface, and the second physical camera corresponding to the second preview image is a wide-angle camera.

[0095] In another embodiment, step S102 includes: based on the first physical camera being a telephoto camera, in response to a zoom operation, the second zoom ratio is less than the first zoom ratio, a second preview image is displayed on the camera preview interface, and the second physical camera corresponding to the second preview image is a wide-angle camera or an ultra-wide-angle camera.

[0096] It can be understood that in the above embodiment, since the logical cameras supported by the third-party application include multiple physical cameras, such as a wide-angle camera, an ultra-wide-angle camera and a telephoto camera, and the multi-camera switching permission is open to the third-party application, when the zoom ratio or the distance between the electronic device and the subject changes, the Pipeline can switch the real-time processing paths corresponding to different physical cameras accordingly, thereby switching to different physical cameras, thereby improving the photo performance and shooting effects of the third-party application.

[0097] In some embodiments, in a scenario where the third-party application turns off the shooting function and the system camera application starts the shooting function, the image processing method further includes: based on the third-party application turning off the shooting function and the system camera application starting the shooting function, displaying a third preview image on the preview interface of the system camera application. The third preview image is associated with the first physical camera, and the zoom ratio corresponding to the third preview image is the third zoom ratio. In response to the zoom operation and / or the change in the distance between the electronic device and the photographed object, a fourth preview image is displayed on the preview interface. The fourth preview image is associated with the second physical camera, and the zoom ratio corresponding to the fourth preview image is the fourth zoom ratio.

[0098] In the above embodiment, in the scenario where the third-party application turns off the shooting function and the system camera application starts the shooting function, since the logical cameras supported by the system camera application include multiple physical cameras, such as a wide-angle camera, an ultra-wide-angle camera, and a telephoto camera, and the multi-camera switching permission is open to the system camera application, when the zoom ratio or the distance between the electronic device and the subject changes, it can switch to a different physical camera accordingly, thereby improving the system camera application's shooting performance and shooting effect.

[0099] In some other embodiments, in the scenario where the third-party application turns off the shooting function and the system camera application starts the shooting function, the image processing method further includes: based on the third-party application turning off the shooting function and the system camera application starting the shooting function, displaying a fifth preview image on the preview interface of the system camera application. The fifth preview image is associated with the first physical camera, and the zoom ratio corresponding to the fifth preview image is the fifth zoom ratio. In response to the zoom operation and / or the change in the distance between the electronic device and the photographed object, the fifth preview image is displayed on the preview interface.

[0100] In the above embodiment, in the scenario where the third-party application turns off the shooting function and the system camera application starts the shooting function, since the original logical camera that supports the separate physical camera is the logical camera called by default by the third-party application, and the physical camera configuration of the logical camera called by default by the third-party application is modified, a new logical camera that supports the separate physical camera is added, so that the system camera application can use the separate physical camera to take pictures by calling the newly added logical camera.

[0140] The pressure sensor 180A is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A can be set on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. The capacitive pressure sensor can be a parallel plate including at least two conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 can also calculate the touch position according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities can correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

[0143] The magnetic sensor 180D includes a Hall sensor. The electronic device 100 can use the magnetic sensor 180D to detect the opening and closing of the flip leather case. In some embodiments, when the electronic device 100 is a flip phone, the electronic device 100 can detect the opening and closing of the flip cover according to the magnetic sensor 180D. Then, according to the detected opening and closing state of the leather case or the opening and closing state of the flip cover, the flip cover can be automatically unlocked.

[0144] The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in all directions (generally three axes).

The light emitting diode may be an infrared light emitting diode. The electronic device 100 emits infrared light outward through the light emitting diode. The electronic device 100 uses a photodiode to detect infrared reflected light from nearby scenes. When sufficient reflected light is detected, it can be determined that there is a scene near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 can determine that there is no scene near the electronic device 100. The electronic device 100 can use the proximity light sensor 180G to detect that the user holds the electronic device 100 close to the ear to talk, so as to automatically turn off the screen to save power. The proximity light sensor 180G can also be used in leather case mode and pocket mode to automatically unlock and lock the screen.

[0147] The ambient light sensor 180L is used to sense the ambient light brightness. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the perceived ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures.
