Camera application control method and terminal device

Technical Field

The present application relates to the field of terminal technology, and in particular to a camera application control method and terminal device.

Background technique

Terminal devices generally include a camera application, and users can use the camera application to take photos and videos. Currently, when running the camera application, the terminal device may encounter the following problems:

When opening a camera application or switching camera modes (for example, switching from photo mode to video mode or from video mode to photo mode), a black screen may appear on the terminal device, seriously affecting the user experience.

Summary of the invention

The present application provides a control method and terminal device for a camera application, which are helpful in reducing the probability of a black screen appearing when the camera application is opened or the camera mode is switched.

In a first aspect, the present application provides a method for controlling a camera application, which can be applied to a terminal device, wherein the terminal device includes a first camera module and a physical layer (PHY) device. The method provided by the present application includes: detecting a first operation of a user on a camera application, wherein the first operation is used to open the camera application, or the first operation is used to switch a camera mode of the camera application; in response to the first operation, enabling the first camera module at a first moment; enabling the PHY device at a second moment, wherein the second moment is later than the first moment, and the second moment is within a first time period, wherein the first time period is a time period when the power-on pins of the first camera module are all at a high level.

The first operation may be a click operation, a slide operation, or a double-click operation of the user on the camera application, which is not limited in this embodiment of the present application.

The first camera module is a camera module serving the first operation.

Exemplarily, the terminal device includes three camera modules, which are camera module 1, camera module 2, and camera module 3. The terminal device can use camera module 1 when the camera application is opened, use camera module 2 in portrait mode, and use camera module 3 in video mode. If the first operation is used to open the camera application, the terminal device detects the first operation, and the terminal device can enable camera module 1 at the first moment. If the first operation is used to switch to the portrait mode of the camera application, the terminal device can enable camera module 2 at the first moment. If the first operation is used to switch to the video mode of the camera application, the terminal device can enable camera module 3 at the first moment.

In response to the first operation, the terminal device may first power on the first camera module, and the power-on timing sequence of the first camera module is LP00, LP10 and LP11. The first moment is within this power-on timing sequence.

The terminal device enables the first camera module at the first moment, which may specifically include: when the terminal device detects that the first moment has arrived, sending an enable instruction to the first camera module, the enable instruction is used to instruct the first camera module to enable. After receiving the enable instruction, the first camera module can be enabled based on the enable instruction. At this time, the first camera module has the ability to obtain image data, but does not obtain image data.

The second moment is later than the first moment, which can also be referred to as the second moment being after the first moment, and the present application embodiment does not limit this. If the second moment is later than the first moment, the terminal device first enables the first camera module and then enables the PHY device.

The terminal device enables the PHY device at the second moment, which may specifically include: when the terminal device detects that the second moment has arrived, the terminal device sends an enable instruction to the PHY device, the enable instruction being used to instruct the PHY device to enable. After receiving the enable instruction, the PHY device may enable itself based on the enable instruction.

The first time period is the time period when the power-on pins of the first camera module are all at a high level, that is, the LP11 duration. At this time, the PHY device is enabled, and the power-on timing of the first camera module is within the LP11 duration. The PHY device has the ability to receive and acquire image data.

The control method of the camera application provided in the present application detects a first operation of the user on the camera application, and in response to the first operation, the camera module can be enabled, and then the PHY device can be enabled. After the PHY device is enabled, the power-on timing of the camera module is in LP11, so that the PHY device can receive image data after being enabled, which is beneficial to avoiding a black screen on the camera interface and can improve the user experience.

In combination with the first aspect, in certain implementations of the first aspect, the first moment is at the starting moment of the second time period, the difference between the second moment and the first moment is greater than or equal to the first duration, and the difference is less than or equal to the second duration, the first duration is the duration of the second time period, the second duration is the sum of the duration of the second time period and the duration of the first time period, and the second time period is the time period when the first pin of the power-on pin of the first camera module is at a high level and the second pin is at a low level.

The second period is a period in which the first pin of the power-on pin of the first camera module is at a high level and the second pin is at a low level, that is, LP10. The first moment may be located at the starting moment of the second period, and the first moment is located at the starting moment of LP10. The first duration is the duration of the second period, that is, the duration of LP10. The difference between the second moment and the first moment is greater than or equal to the duration of LP10.

The first time period is LP11, the second time period is the sum of the second time period and the first time period, and the second time period is (LP10+LP11). The difference between the second moment and the first moment is less than or equal to (LP10+LP11).

If the difference between the second moment and the first moment is greater than or equal to the first duration, and less than or equal to the second duration, then the difference between the second moment and the first moment is greater than or equal to the LP10 duration, and less than or equal to (LP10+LP11).

In combination with the first aspect, in certain implementations of the first aspect, the terminal device includes first configuration information, and the first configuration information is used to indicate a camera module in the terminal device that needs to adjust the enable time of the PHY device; wherein the camera module indicated by the first configuration information includes a first camera module.

The first configuration information may be expressed in the form of a configuration file. The first configuration information is used to indicate the camera module in the terminal device that needs to adjust the enabling time of the PHY device, and the first configuration information may include the name or identifier of the camera module that needs to adjust the enabling time of the PHY device.

If the camera module indicated by the first configuration information does not include the first camera module, that is, the first camera module is not a camera module that requires adjusting the enabling time of the PHY device, the terminal device may not execute the subsequent steps provided in the embodiment of the present application, and may use the method of the prior art to start the first camera module.

The control method of the camera application provided in the present application indicates, through the first configuration information, the camera module in the terminal device whose enabling time of the PHY device needs to be adjusted, and only the camera module indicated by the first configuration information is adjusted. Compared with adjusting all the camera modules in the terminal device, the change is smaller.

In combination with the first aspect, in certain implementations of the first aspect, the terminal device also includes a second camera module, which is not included in the camera module indicated by the first configuration information; the method also includes: detecting a second operation of the user on the camera application, the second operation is used to switch the camera mode of the camera application, and the second operation is different from the first operation; in response to the second operation, enabling the PHY device at a third moment; enabling the second camera module at a fourth moment, and the fourth moment is later than the third moment.

The second camera module is not included in the camera modules indicated by the first configuration information, that is, the second camera module is not a camera module that requires adjusting the enabling time of the PHY device.

The second operation is different from the first operation. If the first operation is used to open the camera application, the second operation may be used to switch the camera mode of the camera application. If the first operation is used to switch the camera mode of the camera application, the second operation may also be used to switch the camera mode of the camera application, but the camera mode switched by the first operation is different from the camera mode switched by the second operation.

The second camera module is not a camera module that requires adjustment of the enabling time of the PHY device. When the terminal device detects the second operation of starting the second camera module, in response to the second operation, the PHY device is enabled at a third moment, and the second camera module is enabled at a fourth moment. The fourth moment is later than the third moment. That is to say, the terminal is configured to enable the PHY device before enabling the second camera module.

The terminal device can adopt the method of the prior art to enable the PHY device before enabling the second camera module.

The control method of the camera application provided by the present application can enable the PHY device before enabling the second camera module when the second camera module is not the camera module that needs to adjust the enabling time of the PHY device and the terminal device detects the second operation of starting the second camera module. These two control methods can be switched back and forth according to different camera modules, which is highly flexible.

In combination with the first aspect, in certain implementations of the first aspect, the third moment and the fourth moment are both within a third time period, and the third time period is a time period when the power-on pins of the second camera module are all at a high level.

The third time period is the time period when the power-on pins of the second camera module are all at a high level, that is, the LP11 duration.

In response to the second operation, the terminal device may first power on the second camera module, and the power-on timing of the second camera module may be LP11. When the power-on timing of the second camera module is within LP11, the terminal device may first enable the PHY device and then enable the second camera module. When the PHY device is enabled, the power-on timing of the second camera module is within LP11, and the PHY device has the ability to receive image data after being enabled.

The control method of the camera application provided in the present application can enable the PHY device first and then enable the second camera module within the third time period, without adjusting the enabling time of the PHY device, which is beneficial to improving the efficiency of starting the second camera module.

In combination with the second aspect, in certain implementations of the second aspect, the first moment is at the starting moment of the second time period, the difference between the second moment and the first moment is greater than or equal to the first duration, and the difference is less than or equal to the second duration, the first duration is the duration of the second time period, the second duration is the sum of the duration of the second time period and the duration of the first time period, and the second time period is the time period when the first pin of the power-on pin of the first camera module is at a high level and the second pin is at a low level.

Detailed ways

The technical solution in this application will be described below in conjunction with the accompanying drawings.

Terminal devices generally include a camera application, and users can use the camera application to take photos and videos. Currently, when a terminal device runs a camera application, the following problems may occur: when the camera application is opened or the camera mode is switched (for example, from the photo mode to the video mode or from the video mode to the photo mode), the terminal device will display a black screen, which seriously affects the user experience.

The embodiment of the present application takes a mobile phone as an example of a terminal device and introduces in detail the scenario where a black screen appears in a camera application.

In one possible scenario, when the user opens the camera application, a black screen appears on the phone. Figure 1 shows a schematic diagram of opening a camera application. As shown in interface a in Figure 1, the desktop of the mobile phone includes icons of multiple applications, wherein the icons of these multiple applications include a camera application. The user can open the camera application by clicking the icon of the camera application. When the mobile phone detects that the user clicks the camera application icon, in response to the operation, the mobile phone can display the camera interface, that is, display interface b in Figure 1. As shown in interface b in Figure 1, the camera interface displays a black screen, or the camera interface displays an image after a period of black screen. This situation will seriously affect the user experience.

In another possible scenario, when the user switches the camera mode, a black screen appears on the mobile phone. FIG. 2 shows a schematic diagram of a camera mode switch. As shown in interface a in FIG. 2 , the camera application of the mobile phone can provide the user with video mode, photo mode and portrait mode. The camera interface of the mobile phone can display video options, photo options and portrait options. In interface a in FIG. 2 , the camera application is in photo mode. The user can switch the photo mode to portrait mode by clicking the portrait option. When the mobile phone detects that the user clicks the portrait option, in response to the operation, the mobile phone switches to portrait mode and can display interface b in FIG. 2 . As shown in interface b in FIG. 2 , the mobile phone switches to portrait mode, but the interface is black. This situation will seriously affect the user experience.

When the user opens the camera application or switches the camera mode, the mobile phone displays a black screen, that is, the image data obtained by the camera of the mobile phone is not displayed. In order to determine why the mobile phone cannot display the image data obtained by the camera, the embodiment of the present application studies the transmission of the image data obtained by the camera.

Exemplarily, FIG3 shows a schematic diagram of image data transmission. As shown in FIG3, the mobile phone includes a camera module, a processor and a display device. The camera module is used to acquire image data. The processor includes a physical layer (Physical, PHY) device. Among them, the processor may be a Qualcomm processor (Qualcomm processor may also be referred to as a Qualcomm platform), but the embodiments of the present application are not limited thereto. The display device is used to display image data. The PHY device is used to receive image data sent by the camera module, and may also be referred to as a PHY device or a PHY chip, which is not limited in the embodiments of the present application.

The processor detects the operation of the user opening the camera application or switching the camera mode, and in response to the operation, can instruct the camera module to obtain image data. The processor can receive the image data sent by the camera module through the PHY device using the mobile industry processor interface (MIPI) protocol. The processor can control the display device to display the image data obtained from the PHY device.

The data transmission between the PHY device and the camera module needs to meet the timing requirements specified by the MIPI protocol. The MIPI protocol specifies two modes, namely low power (LP) mode and high speed (HS) mode. The LP mode is the preparation stage before image data transmission, and the HS mode is the image data transmission stage. The LP mode may include LP00, LP10, and LP11. LP00 is used to indicate that the power-on pins of the camera module are all low level 0; LP10 is used to indicate that one pin of the power-on pin of the camera module is low level 0 and the other pin is high level 1; LP11 is used to indicate that the power-on pins of the camera module are all high level 1. Among them, the power-on pins of the camera module may include the PWDN (power down) pin and the RESETB pin.

Camera modules produced by different manufacturers use different LP modes. Some manufacturers produce camera modules with power-on timings of LP00, LP10, and LP11. The durations of LP00, LP10, and LP11 are set by the manufacturer during production.

The process of the processor controlling the camera module is to power on first, enable, and finally transmit image data. If the power-on timing of the camera module is LP00, LP10, and LP11, after the processor powers on the camera module, the timing of the camera module is in LP00. When the LP00 duration is reached and it is in LP10, the processor controls the camera module to be enabled and transmits image data in the timing corresponding to the HS mode after the LP11 duration. Among them, the processor controls the camera module to be enabled, which can be understood as the stage when the camera is ready to start working and can obtain image data but has not obtained image data.

Currently, the processor detects the user opening the camera application or switching the camera mode. In response to the operation, the camera can be powered on, and the PHY device can be enabled first, and then the camera module can be enabled. Finally, the image data obtained by the camera module can be received through the PHY device and the image data can be displayed.

If the power-on sequence of the camera module is LP00, LP10 and LP11, when the processor controls the PHY device to be enabled, the power-on sequence of the camera module is in LP00, and when the processor controls the camera module to be enabled, the power-on sequence of the camera module is in LP10. However, the PHY device can only receive image data sent by the camera module when the power-on sequence of the camera module is in LP11. Therefore, in this implementation method, the PHY device cannot work normally when it is enabled. The PHY device can only receive image data sent by the camera module when the power-on sequence of the camera module is in LP11. During the time from when the PHY device is enabled to when the PHY device can receive image data sent by the camera module, the mobile phone is in a black screen state. It should be noted that when the PHY device is enabled and the power-on sequence of the camera module is in LP11, the PHY device only has the ability to receive image data, but no image data is received at this time.

Exemplarily, FIG4 shows a schematic diagram of the timing of the LP mode. The power-on timing of the camera module is LP00, LP10 and LP11, and the duration of LP00, the duration of LP10 and the duration of LP11 are set by the manufacturer during production. The processor detects the operation of the user opening the camera application or switching the camera mode. In response to the operation, the camera module can be powered on. The power-on timing of the camera module is in LP00. Within the LP00 duration, the processor controls the PHY device to be enabled. At this time, the power-on timing of the camera module is not in LP11, and the PHY device cannot work normally, that is, it does not have the ability to receive image data. When the LP00 duration is reached and it is in LP10, the processor controls the camera module to be enabled. Within the LP10 duration, the PHY device does not have the ability to receive image data. When the LP10 duration is reached and it is in LP11, the PHY device has the ability to receive image data, and after the LP11 duration, it is in the timing corresponding to the HS mode, and the PHY device receives the image data acquired by the camera module. In this implementation, the PHY device needs to wait for a period of time before it can receive image data and then send it to the display device for display, resulting in a black screen on the camera interface.

To summarize, the reason why a black screen appears on the terminal device when the user opens the camera application or switches the camera mode is that the timing of the camera module in the terminal device after power-on is LP00, LP10 and LP11, and when the device for receiving image data included in the processor of the terminal device (such as the above-mentioned PHY device) is enabled, the timing of the camera module is in LP00, and it is necessary to wait until the timing of the camera module is in LP11 before it can have the ability to receive image data.

In view of this, an embodiment of the present application provides a camera application control method and terminal device, which detects the operation of a user opening a camera application or switching a camera mode. In response to the operation, the camera can be powered on, and the camera module can be enabled first, and then the PHY device can be enabled. After the PHY device is enabled, the timing of the camera module is in LP11, that is, after the camera module is powered on, when the timing of the camera module is in LP10, the camera module is controlled to be enabled, and when the timing of the camera module is in LP11, the camera module is controlled to be enabled. After the PHY device is enabled, the PHY device has the ability to receive image data, which is beneficial to reduce the probability of a black screen on the camera interface and can improve the user experience.

The method provided in the embodiment of the present application can be applied to any terminal device including camera applications, such as mobile phones, tablet computers, personal computers (PC), etc. The terminal device can also be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a mobile phone, a smart TV, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiment of the present application does not limit the specific technology and specific device form adopted by the terminal device.

In order to better understand the embodiment of the present application, the hardware structure of the terminal device of the embodiment of the present application is introduced below. Exemplarily, Figure 5 is a hardware structure diagram of a terminal device provided in an embodiment of the present application. As shown in Figure 5, the terminal device may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, a sensor module 180, a button 190, an indicator 192, a camera 193, and a display screen 194, etc.

It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the terminal device. In other embodiments of the present application, the terminal device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

The embodiment of the present application only focuses on the processor 110, the camera 193, and the display screen 194 of the terminal device. The terminal device shown in FIG5 can obtain image data through the camera 193, receive the image data through the PHY device in the processor 110, and finally display the image data on the display screen 194. The embodiment of the present application only describes the processor 110, the camera 193, and the display screen 194.

The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and/or a neural-network processing unit (NPU), etc. Among them, different processing units may be independent devices or integrated in one or more processors. A memory may also be provided in the processor 110 for storing instructions and data. It is understandable that the processor 110 may be the processor in the example shown in FIG. 3 above, may include a PHY device, and may have the functions shown in FIG. 3 above.

The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

In some embodiments, the processor 110 may include one or more interfaces. The interface may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver/transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input/output (GPIO) interface, a subscriber identity module (SIM) interface, and/or a universal serial bus (USB) interface, etc.

The terminal device implements the display function through the GPU, the display screen 194 and the AP. The GPU is a microprocessor for image processing, which connects the display screen 194 and the AP. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs, which execute program instructions to generate or change display information.

The display screen 194 is used to display images, display videos, and receive sliding operations, etc. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED), a flexible light-emitting diode (FLED), Miniled, MicroLed, Micro-oLed, a quantum dot light emitting diode (QLED), etc. In some embodiments, the terminal device may include 1 or N display screens 194, where N is a positive integer greater than 1.

The terminal device can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and AP.

Among them, ISP is used to process the data fed back by camera 193. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to ISP for processing and converts it into an image visible to the naked eye. ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, ISP can be set in camera 193.

The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the terminal device may include 1 or N cameras 193, where N is a positive integer greater than 1.

Video codecs are used to compress or decompress digital videos. Terminal devices can support one or more video codecs. In this way, terminal devices can play or record videos in multiple coding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

The AP outputs a sound signal through an audio device (not limited to the speaker 170A, the receiver 170B, etc.), or displays an image or video through the display screen 194. In some embodiments, the modem processor can be an independent device. In other embodiments, the modem processor can be independent of the processor 110 and be set in the same device as the mobile communication module 150 or other functional modules.

The software system of the terminal device can adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The layered architecture can adopt an Android system, an Apple (IOS) system, or other operating systems, which are not limited in the embodiments of the present application. The following takes the Android system of the layered architecture as an example to illustrate the software structure of the terminal device.

FIG6 is a software structure diagram of a terminal device applicable to an embodiment of the present application. The layered architecture divides the software system of the terminal device into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system can be divided into four layers, from top to bottom, namely, the application layer (applications), the application framework layer (application framework), the Android runtime (Android runtime) and the system library, the hardware abstraction layer and the kernel layer (kernel). The embodiment of the present application only improves the hardware abstraction layer.

The application layer may include a series of application packages, and the application layer runs applications by calling the application programming interface (API) provided by the application framework layer. As shown in FIG6 , the application package may include applications such as camera, gallery, calendar, memo, and map.

The application framework layer provides API and programming framework for the applications in the application layer. The application framework layer includes some predefined functions. As shown in FIG6 , the application framework layer may include a window manager, a content provider, and a view system.

The window manager is used to manage window programs. The window manager can obtain the display size, determine whether there is a status bar, lock the screen, capture the screen, etc. The content provider is used to store and obtain data and make the data accessible to applications. The data can include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc. The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, etc. The view system can be used to build applications. The display interface can be composed of one or more views. For example, the display interface including the SMS notification icon can include a view for displaying text and a view for displaying pictures.

The Android system runtime includes a core library and a virtual machine. The Android system runtime is responsible for the scheduling and management of the Android system. The core library consists of two parts: one is the function that the Java language needs to call, and the other is the Android core library. The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection. The system library can contain modules with multiple functions, such as: surface manager, media library, and 3D graphics processing library.

The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications. The media library supports playback and recording of multiple common audio and video formats, as well as static image files. The media library can support multiple audio and video encoding formats, such as JPG, PNG, etc. The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis and layer processing.

The hardware abstraction layer includes a camera service module. The camera service module is used to provide services for camera applications. The camera service module may include a power-on module, an enable module and a configuration module. The configuration module includes configuration information, which is used to indicate the camera module for which the enable time of the PHY device needs to be adjusted. The configuration module can be used to determine whether the camera module started by the user is a camera module for which the enable time of the PHY device needs to be adjusted, and send indication information to the power-on module based on the judgment result. The power-on module can power on the camera module included in the terminal device based on the indication information sent by the configuration module. Among them, the camera power-on timing may include LP00, LP10 and LP11, or the camera power-on timing may be LP11. The power-on module can also determine the enable time of the PHY device and the camera module, and send this information to the enable module. The enable module can enable the PHY device and the camera module based on the information sent by the power-on module.

The kernel layer is a layer between hardware and software. The kernel layer is used to drive the hardware to make the hardware work. The kernel layer at least includes a display driver, a camera driver, and a Bluetooth driver, etc., which are not limited in the embodiments of the present application.

Exemplarily, FIG7 shows a schematic flow chart of a control method 700 for a camera application. The method 700 can be executed by a terminal device including a first camera module and a PHY device, for example, a mobile phone. The hardware structure diagram of the terminal device can be as shown in FIG5 above, and the software structure diagram of the terminal device can be as shown in FIG6 above, but the embodiments of the present application are not limited thereto. The method 700 can be applicable to the scenarios shown in FIG1 and FIG2 above, but the embodiments of the present application are not limited thereto. It should be noted that the PHY device can be included in the processor of the terminal device, and the method provided in the embodiments of the present application can also be specifically executed by the processor of the terminal device. For example, a Qualcomm processor in a terminal device.

As shown in FIG. 7 , the method 700 may include the following steps:

S701: Detect a first operation of a user on a camera application, where the first operation is used to open the camera application, or the first operation is used to switch a camera mode of the camera application.

The first operation may be a click operation, a slide operation, or a double-click operation of the user on the camera application, which is not limited in this embodiment of the present application.

If the first operation is used to open the application camera, the first operation can be the operation shown in Figure 1 above, but the embodiment of the present application is not limited thereto. If the first operation is used to switch the camera mode of the camera application, the first operation can be the operation shown in Figure 2 above, but the embodiment of the present application is not limited thereto.

S702: In response to a first operation, enable a first camera module at a first moment.

The first camera module is a camera module serving the first operation.

Exemplarily, the terminal device includes three camera modules, which are camera module 1, camera module 2, and camera module 3. The terminal device can use camera module 1 when the camera application is opened, use camera module 2 in portrait mode, and use camera module 3 in video mode. If the first operation is used to open the camera application, the terminal device detects the first operation, and the terminal device can enable camera module 1 at the first moment. If the first operation is used to switch to the portrait mode of the camera application, the terminal device can enable camera module 2 at the first moment. If the first operation is used to switch to the video mode of the camera application, the terminal device can enable camera module 3 at the first moment.

In response to the first operation, the terminal device may first power on the first camera module, and the power-on timing sequence of the first camera module is LP00, LP10 and LP11. The first moment is within this power-on timing sequence.

The terminal device enables the first camera module at the first moment, which may specifically include: when the terminal device detects that the first moment has arrived, sending an enable instruction to the first camera module, the enable instruction is used to instruct the first camera module to enable. After receiving the enable instruction, the first camera module can be enabled based on the enable instruction. At this time, the first camera module has the ability to obtain image data, but does not obtain image data.

S703, enabling the PHY device at a second moment, the second moment is later than the first moment, and the second moment is within a first time period, and the first time period is a time period when the power-on pins of the first camera module are all at a high level.

The second moment is later than the first moment, which can also be referred to as the second moment being after the first moment, and the present application embodiment does not limit this. If the second moment is later than the first moment, the terminal device first enables the first camera module and then enables the PHY device.

The terminal device enables the PHY device at the second moment, which may specifically include: when the terminal device detects that the second moment has arrived, the terminal device sends an enable instruction to the PHY device, the enable instruction being used to instruct the PHY device to enable. After receiving the enable instruction, the PHY device may enable itself based on the enable instruction.

The first time period is the time period when the power-on pins of the first camera module are all at a high level, that is, the LP11 duration. At this time, the PHY device is enabled, and the power-on timing of the first camera module is within the LP11 duration. The PHY device has the ability to receive and acquire image data.

Optionally, the above-mentioned first moment can be located at the starting moment of the second time period, the difference between the second moment and the first moment is greater than or equal to the first duration, and the difference is less than or equal to the second duration, the first duration is the duration of the second time period, the second duration is the sum of the duration of the second time period and the duration of the first time period, and the second time period is the time period when the first pin of the power-on pin of the first camera module is at a high level and the second pin is at a low level.

The second period is a period in which the first pin of the power-on pin of the first camera module is at a high level and the second pin is at a low level, that is, LP10. The first moment may be located at the starting moment of the second period, and the first moment is located at the starting moment of LP10. The first duration is the duration of the second period, that is, the duration of LP10. The difference between the second moment and the first moment is greater than or equal to the duration of LP10.

The first time period is LP11, the second time period is the sum of the second time period and the first time period, and the second time period is (LP10+LP11). The difference between the second moment and the first moment is less than or equal to (LP10+LP11).

If the difference between the second moment and the first moment is greater than or equal to the first duration, and less than or equal to the second duration, then the difference between the second moment and the first moment is greater than or equal to the LP10 duration, and less than or equal to (LP10+LP11).

Exemplarily, FIG8 shows a timing diagram of a control method for a camera application. The power-on timing of the first camera module is LP00, LP10, and LP11, and the duration of LP00, the duration of LP10, and the duration of LP11 are set by the manufacturer during production. The terminal device detects the operation of the user opening the camera application or switching the camera mode. In response to the operation, the first camera module can be powered on. The power-on timing of the first camera module is in LP00. When the LP00 duration is reached and it is in LP10, the terminal device controls the first camera module to be enabled at the first moment (i.e., the starting moment of LP10). When the LP10 duration is reached and it is in LP11, the terminal device controls the PHY device to be enabled at the second moment (i.e., within the duration of LP11). At this time, the PHY device has the ability to receive image data. Within the timing corresponding to the HS mode, the terminal device obtains image data through the first camera module, receives the image data obtained by the first camera module through the PHY device, and finally displays the image data through the display device.

The control method of the camera application provided in the embodiment of the present application detects the first operation of the user on the camera application, and in response to the first operation, the camera module can be enabled, and then the PHY device can be enabled. After the PHY device is enabled, the power-on timing of the camera module is in LP11, so that the PHY device can receive image data after being enabled, which is beneficial to avoiding a black screen on the camera interface and can improve the user experience.

As an optional embodiment, the terminal device may include first configuration information, and the first configuration information is used to indicate a camera module in the terminal device whose enabling time of the PHY device needs to be adjusted; before the above S702, enabling the first camera module at the first moment, method 700 may also include: determining whether the camera module indicated by the first configuration information includes the first camera module; if the camera module indicated by the first configuration information includes the first camera module, enabling the first camera module at the first moment.

The first configuration information may be expressed in the form of a configuration file. The first configuration information is used to indicate the camera module in the terminal device that needs to adjust the enabling time of the PHY device, and the first configuration information may include the name or identifier of the camera module that needs to adjust the enabling time of the PHY device.

Exemplarily, different manufacturers produce different camera modules, and the name or logo of the camera module can be the manufacturer's name. Before the terminal device leaves the factory, the developer can preset the manufacturer's name of the camera module that needs to adjust the enable time of the PHY device in the terminal device as the first configuration information. The terminal device detects an operation to start the camera module, such as the first operation mentioned above, and the terminal device can determine whether the first configuration information includes the started camera module, such as the first camera module. If the first configuration information includes the started camera module, the terminal device enables the first camera module at the first moment.

If the camera module indicated by the first configuration information does not include the first camera module, that is, the first camera module is not a camera module that requires adjusting the enabling time of the PHY device, the terminal device may not execute the subsequent steps provided in the embodiment of the present application, and may use the method of the prior art to start the first camera module.

The control method of the camera application provided in the embodiment of the present application indicates, through the first configuration information, the camera module in the terminal device whose enable time of the PHY device needs to be adjusted, and only the camera module indicated by the first configuration information is adjusted, which requires smaller changes than adjusting all the camera modules in the terminal device.

As an optional embodiment, the terminal device also includes a second camera module, which is not included in the camera module indicated by the first configuration information; the above method may also include: detecting a second operation of the user on the camera application, the second operation is used to switch the camera mode of the camera application, and the second operation is different from the first operation; in response to the second operation, enabling the PHY device at a third moment; enabling the second camera module at a fourth moment, and the fourth moment is later than the third moment.

The second camera module is not included in the camera module indicated by the first configuration information, that is, the second camera module is not a camera module that requires adjusting the enabling time of the PHY device.

The second operation is different from the first operation. If the first operation is used to open the camera application, the second operation may be used to switch the camera mode of the camera application. If the first operation is used to switch the camera mode of the camera application, the second operation may also be used to switch the camera mode of the camera application, but the camera mode switched by the first operation is different from the camera mode switched by the second operation.

The second camera module is not a camera module that requires adjustment of the enabling time of the PHY device. When the terminal device detects the second operation of starting the second camera module, in response to the second operation, the PHY device is enabled at a third moment, and the second camera module is enabled at a fourth moment. The fourth moment is later than the third moment. That is to say, the terminal is configured to enable the PHY device before enabling the second camera module.

The terminal device can adopt the method of the prior art to enable the PHY device before enabling the second camera module.

In the control method of the camera application provided in the embodiment of the present application, when the second camera module is not the camera module that needs to adjust the enabling time of the PHY device, and the terminal device detects the second operation of starting the second camera module, the PHY device can be enabled before enabling the second camera module. These two control methods can be switched back and forth according to different camera modules, and are highly flexible.

Optionally, the third moment and the fourth moment may both be within a third time period, and the third time period is a time period when the power-on pins of the second camera module are all at a high level.

The third time period is the time period when the power-on pins of the second camera module are all at a high level, that is, the LP11 duration.

In response to the second operation, the terminal device may first power on the second camera module, and the power-on timing of the second camera module may be LP11. When the power-on timing of the second camera module is within LP11, the terminal device may first enable the PHY device and then enable the second camera module. When the PHY device is enabled, the power-on timing of the second camera module is within LP11, and the PHY device has the ability to receive image data after being enabled.

The camera application control method provided in the embodiment of the present application can enable the PHY device first and then enable the second camera module within the third time period, without adjusting the enabling time of the PHY device, which is beneficial to improving the efficiency of starting the second camera module.

The terminal device provided in the embodiment of the present application may include a configuration module, a power-on module and an enabling module. The control method of the camera application provided in the embodiment of the present application may be executed by the configuration module, the power-on module and the enabling module.

For example, Fig. 9 shows a schematic flow chart of a camera application control method 900. As shown in Fig. 9, the method 900 may include the following steps:

S901. When a first operation of a user on a camera application is detected, the configuration module determines whether the first configuration information includes a first camera module, wherein the first operation is used to start the first camera module.

The configuration module includes first configuration information, and the first configuration information is used to indicate the camera module for which the enabling time of the PHY device needs to be adjusted.

S902: If the first configuration information includes the first camera module, the configuration module sends a first power-on instruction to the power-on module, and correspondingly, the power-on module receives the first power-on instruction, wherein the first power-on instruction is used to instruct the power-on module to power on the first camera module.

The first power-on instruction is used to instruct the power-on module to power on the first camera module, and the power-on sequence includes LP00, LP10 and LP11.

If the first configuration information does not include the first camera module, the configuration module may send a second power-on instruction to the power-on module, and the power-on module receives the second power-on instruction, wherein the second power-on instruction is used to instruct the power-on module to power on the first camera module, and the power-on timing is LP11.

S903: The power-on module powers on the first camera module based on the first power-on instruction, and determines the enabling time of the first camera module and the PHY device.

Based on the first power-on instruction, the power-on module can determine that the enabling time of the first camera module is the first moment and the enabling time of the PHY device is the second moment. The second moment is later than the first moment, and the second moment is within the first time period, and the first time period is the time period when the power-on pins of the first camera module are all high level.

S904: The power-on module may send an enable instruction to the enable module, and correspondingly, the enable module receives the enable instruction, wherein the enable instruction is used to instruct the enable module to enable based on the determined enable time.

The enabling instruction may include the enabling time of the first camera module and the PHY device, so as to instruct the enabling module to enable based on the determined enabling time.

S905. The enabling module enables the first camera module at a first moment and enables the PHY device at a second moment based on the enabling instruction.

The control method of the camera application provided in the embodiment of the present application enables the PHY device to receive image data after being enabled through the configuration module, the power-on module and the enabling module, which is beneficial to avoid a black screen on the camera interface and can improve the user experience.
