The following describes exemplary workflow of the software and hardware of the electronic device 100 in connection with capturing a photo scene.
When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, timestamp of the touch operation, and the like). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the example that the touch operation is a touch click operation, and the control corresponding to the click operation is the control of the icon of the "camera application" shown above, the camera application calls the interface of the application framework layer to start the camera application, and after the camera application is started, the interface of the application framework layer can be called, so that the camera drive is started by calling the kernel layer, and a still image or video is captured by the camera 193.
Referring to fig. 3, a flowchart of a method for detecting a camera provided in the present application is shown, and for convenience of understanding, the method shown in the present application is further explained and explained below by taking the electronic device with the structure shown in fig. 1 and fig. 2 as an example, wherein the electronic device runs the first application, and the first application includes the camera application and the factory test application, etc. described above.
And 304, detecting the connection state of the electronic equipment and the camera, and setting the first application to be in a sleep state if the electronic equipment is in the non-connection state.
In this step, when the electronic device and the camera are not in a connected state, that is, when there is no camera to be tested, the switching chip may not receive information acquired by the camera, and may not report the state of the electronic device not connected to the camera to the first application.
The detecting of the connection state of the electronic device and the camera may include various methods, for example, a detection thread may be created, and the connection state of the electronic device and the camera may be detected in real time through the detection thread, or the connection state of the electronic device and the camera may also be detected in real time through a hardware abstraction layer related to the first application.
The electronic device includes but is not limited to a terminal device such as a car machine, 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 is not operated, the related data of the first application is temporarily stored in the cache, and the first application can continue to operate after being awakened.
When the electronic equipment detects that the camera is inserted into the electronic equipment, the first application is awakened, so that the first application runs.
Specifically, the electronic device may obtain configuration data of the camera, where the configuration data includes parameters such as a format, a resolution, and a frame rate of the camera, and the adaptor chip may perform configuration based on the parameters, so that the first application can receive and display image data obtained by the camera based on the parameters.
And 310, receiving and displaying the image data acquired by the camera by the first application.
And after the configuration data is acquired, the first application receives and displays the data acquired by the camera based on the parameters in the configuration data.
The camera detection method can detect the insertion and extraction states of the camera in real time, and continuously detect the camera under the condition that the camera does not need to be closed, so that the detection efficiency is improved, and the cost is reduced.
For convenience of description, the method shown in the present application is explained and explained below by taking the electronic device as a car machine, the camera as an analog camera, and the first application as a camera application as examples.
Referring to fig. 4, a flowchart of a method for detecting a camera according to another embodiment of the present application is specifically described.
At step 402, a detection thread is started.
Specifically, the detection thread is used for detecting the insertion and extraction states of the analog camera on the vehicle. When the analog cameras are inserted into the car machine, the detection process can also read configuration data of each analog camera, the configuration data includes but is not limited to the system, the resolution, the frame rate and the like of the analog cameras, and the first application can display data acquired by the analog cameras based on the configuration data.
In this embodiment, the insertion and extraction states of the analog camera on the in-vehicle device are detected by the detection thread, and the insertion and extraction states of the analog camera on the in-vehicle device are read and detected.
As already shown above, the detection thread may detect whether the analog camera is inserted into the in-vehicle device in real time, for example, the detection thread may poll the register content of the switch chip, determine that the analog camera is inserted into the in-vehicle device if the preset content is read, and enter step 406 when the analog camera is detected to be inserted into the in-vehicle device.
At step 406, the configuration data is read.
As shown above, the detection thread may read the configuration data of the analog camera inserted into the in-vehicle device in real time, and may, for example, poll the register content of the switch chip to read and store all the configuration data of the analog camera.
In one example, the sleep state is entered after the detection thread reads all configuration data.
And after the detection thread reads the configuration data of the analog camera, configuring, and after the configuration is finished, entering step 406.
And step 408, turning on the analog camera.
After the configuration data is acquired, the analog camera can be opened, and if the analog camera is compatible with other cameras or a vehicle machine, the data transmitted by the analog camera can be directly acquired.
For example, a timer may be set to detect whether the analog camera can acquire the image data, for example, the timer is set to be at least 2 times of a frame interval of the analog camera, and if the image data is detected, step 402 is performed, and the switch chip of the in-vehicle device reports the image data acquired from the analog camera to the camera application for display.
If no image data can be detected, step 414 may be entered.
And step 414, detecting whether the analog camera is pulled out.
The detection thread can be awakened to judge whether the simulation camera is currently arranged, if the simulation camera is still inserted into the vehicle machine, when the simulation camera is not compatible with the vehicle machine and other systems, a user can judge through observing a display interface of the vehicle machine. When the user finds that the camera application cannot display data, the user considers that the simulation camera is probably incompatible, the simulation camera can be pulled out, and the user can start to test the next camera.
Or if the detection thread cannot read the information in the switching chip, the analog camera is determined to be pulled out.
It should be noted that, in the present application, when the analog camera is incompatible or the camera is suddenly pulled out and cannot acquire image data, the in-vehicle system does not need to report error information to the first application, but directly detects through the detection thread, and if it is detected that the analog camera has been pulled out from the in-vehicle device, the method proceeds to step 416.
