In other embodiments of the present invention, the electronic device 100 may include more or fewer components than shown, or combine certain components, or separate certain components, or arrange different components. The illustrated components can be realized in hardware, software or a combination of software and hardware.

FIG. 2 is a block diagram of the software structure of the electronic device 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, the application program layer, the application program framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer.

The application layer can consist of a series of application packages.

As shown in Figure 2, the application package may include applications such as camera, gallery, calendar, call, skin care, navigation, WLAN, Bluetooth, music, video, and short message.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 2, the application framework layer can include window managers, content providers, view systems, phone managers, resource managers, notification managers, and so on.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, capture the screen, etc.

Content providers are used to store and retrieve data and make it accessible to applications. Said data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebook, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. The view system can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text message notification icon may include a view for displaying text and a view for displaying pictures.

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears on the top status bar of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, prompting text information in the status bar, issuing a prompt sound, vibrating the electronic device, and flashing the indicator light, etc.

Android Runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program 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.

A system library can include multiple function modules. For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.

The workflow of the software and hardware of the electronic device 100 will be exemplarily described below in conjunction with capturing and photographing scenes.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into original input events (including touch coordinates, time stamps of touch operations, and other information). Raw input events are stored at the kernel level. The application framework layer obtains the original input event from the kernel layer, and identifies the control corresponding to the input event. Take the touch operation as a touch and click operation, and the control corresponding to the click operation is the control of the icon of the "camera application" shown above as an example. The camera application calls the interface of the application framework layer to start the camera application, and the camera application After the application is started, the interface of the application framework layer can be called, and then the camera driver can be started by calling the kernel layer, and still images or videos can be captured through the camera 193 .

Referring to FIG. 3 , it shows a flow chart of a camera detection method provided by the present application. For the convenience of understanding, the method shown in the present application will be further described below in conjunction with the electronic device having the structure shown in FIG. 1 and FIG. 2 as an example. , wherein the electronic device runs a first application, and the first application includes the above-mentioned camera application and factory test application.

Step 304, detecting the connection state of the electronic device and the camera, and setting the first application to a sleep state if it is not connected.

In this step, when the electronic device is not connected to the camera, that is, when there is no camera to be tested, the adapter chip will not receive the information obtained by the camera, and may not report the state that the electronic device is not connected to the camera to the first The application, because the first application will not receive the reported data, causes the first application to enter a sleep state.

Detecting the connection state of the electronic device and the camera may include multiple methods. For example, a detection thread may be created to detect the connection state of the electronic device and the camera in real time through the detection thread, or it may also be implemented in real time through the hardware abstraction layer related to the first application. Detect the connection status of the electronic device and the camera in a timely manner.

Wherein, the electronic device includes but is not limited to a terminal device such as a vehicle, the camera includes but is not limited to an analog camera, and the connection state includes a physical connection, and may also include a communication connection and the like. The first application enters the sleep state to indicate that the first application does not run, and its related data is temporarily stored in the cache, and can continue to run after the first application wakes up.

Step 306 , detecting a first operation of the user inserting a camera into the electronic device, and waking up the first application in response to the detected first operation.

When the electronic device detects that the camera is plugged into the electronic device, it wakes up the first application, so that the first application runs.

Step 308, acquire configuration data of the camera, and the configuration data is used by the first application to display the image data acquired by the first camera.

Specifically, the electronic device can acquire configuration data of the camera. For example, the configuration data includes parameters such as the format, resolution, and frame rate of the camera. The adapter chip can be configured based on these parameters, so that the first application can parameter, receive and display the image data acquired by the camera.

Step 310, the first application receives and displays the image data acquired by the camera.

After acquiring the configuration data, the first application receives and displays the data acquired by the camera based on the parameters in the configuration data.

The detection method of the camera shown in this application can detect the plug-in and pull-out status of the camera in real time, and continuously detect the camera without turning off the camera, which improves the detection efficiency and reduces the cost.

For the convenience of description, the following takes the electronic device as a vehicle, the camera as an analog camera, and the first application as a camera application as examples to continue explaining and illustrating the method shown in this application.

Referring to FIG. 4 , it specifically relates to a flow chart of a camera detection method provided by another embodiment of the present application.

Step 402, start the detection thread.

Specifically, the detection thread is used to detect the plug-in and pull-out status of the analog camera on the vehicle. When the analog camera is inserted into the car, the detection process can also read the configuration data of each analog camera, which includes but not limited to the standard, resolution, and frame rate of the analog camera. The first application can be based on these configuration data Display the data acquired by the simulated camera.

It should be noted that in this embodiment, the detection thread is used to detect the plug-in and pull-out status of the analog camera on the car machine, read and detect the plug-in and pull-out status of the analog camera on the car machine, etc. Of course, other methods can also be used to detect Or read, without limitation here.

Step 404, detecting the user's first operation of inserting the analog camera into the car machine.

It has been shown above that the detection thread can detect whether the analog camera is inserted into the vehicle in real time. On the vehicle, when it is detected that the analog camera is plugged into the vehicle, go to step 406 .

Step 406, read configuration data.

It has been shown above that the detection thread can read the configuration data of the analog camera inserted into the vehicle in real time. For example, the detection thread can poll the register content of the adapter chip to read all the configuration data of the analog camera and save.

In one example, after the detection thread has read all the configuration data, it enters the sleep state.

Configuration is performed after the detection thread reads the configuration data of the analog camera, and step 406 is entered after the configuration is completed.

Step 408, open the analog camera.

After obtaining the configuration data, you can turn on the analog camera. If the analog camera is compatible with other cameras or the car, you can directly obtain the data sent by the analog camera.

Step 410, detecting whether the analog camera has acquired image data.

Exemplarily, it is possible to detect whether the analog camera can acquire image data by setting a timer, for example, set the timer to at least twice the frame interval of the analog camera, if image data is detected, go to step 402, and the The adapter chip reports the image data obtained from the analog camera to the camera application for display.

If image data cannot be detected, go to step 414 .

Step 414, detecting whether the analog camera is pulled out.

You can wake up the detection thread to determine whether there is an analog camera. If the analog camera is still plugged into the car, the analog camera may not be compatible with the car and other systems. The user can judge by observing the car display interface. When the user finds that the camera application cannot display data, it is considered that the analog camera is probably incompatible, and the camera will be pulled out, and the user can start to test the next camera.

Or, if the detection thread cannot read the information in the adapter chip, it is determined that the analog camera has been pulled out.

It should be noted that, in this application, when the analog camera cannot obtain image data due to incompatibility or suddenly pulling out the camera, the vehicle-machine system does not need to report error information to the first application, but directly detects through the detection thread, and the analog camera state, if it is detected that the analog camera has been pulled out from the car machine, then go to step 416.

Step 416, the camera application goes to sleep.

In the case that the simulated camera has been unplugged, enter the sleep state.

Since the first application will not display the reported information sent by the car system, the camera application does not need to be closed and reopened, but enters a sleep state. When the detection thread detects that a new camera is inserted, the camera application is woken up, thereby realizing continuous testing. Analog camera.
