Embodiment one

Figure 1 is a schematic flowchart of a selfie stick fitting method provided in Embodiment 1 of the present invention. The method can be executed by a selfie stick fitting device, wherein the device can be implemented by software and/or hardware, and can generally be integrated into a mobile in the device. As shown in Figure 1, the method includes:

Step 101: After detecting that the headphone plug is inserted into the mobile device, if it is determined that the voltage value of the microphone terminal has changed, then determine the changed voltage value of the microphone terminal as the button voltage value.

Exemplarily, the mobile device in this embodiment may specifically be a device such as a mobile phone and a tablet computer with a camera function. Specifically, the selfie stick can be a selfie stick with an earphone plug, which can be connected to the earphone jack of the mobile device through the earphone plug, and the mobile device can be controlled to take pictures. The device for executing the method in this embodiment may be embedded in the system bottom layer of the mobile device.

Exemplarily, an earphone plug matched with an earphone jack in an existing mobile device is generally a 3.5 mm four-section plug, including a left audio channel end, a right audio channel end, a ground end, and a microphone (MIC) end. When the headphone plug is inserted into the headphone jack of the mobile device, a certain voltage will be applied to the MIC terminal, and the voltage value from the MIC terminal to ground (hereinafter referred to as MIC) can be read through an analog-to-digital converter (Analog-to-Digital Converter, ADC). terminal voltage value).

In this embodiment, when it is detected that the voltage value of the MIC terminal is within a preset range, it may be determined that the earphone plug is inserted into the mobile device. Exemplarily, when the headphone plug is inserted into the headphone jack of the mobile device, a voltage of 1.9V is generally applied to the MIC terminal, and generally when the read voltage value of the MIC terminal is above 1.2V, it can be determined that the headphone plug is detected Insertion, that is, the above preset range may specifically be between 1.2V and 1.9V.

After detecting that the earphone plug is inserted into the mobile device, if it is determined that the voltage value of the MIC terminal changes, the changed voltage value of the MIC terminal may be determined as the button voltage value. Exemplarily, when the button on the selfie stick is pressed, the processor inside the mobile device will switch the circuit. At this time, the voltage value of the MIC terminal will change, for example, from 1.5V to 0.27V, and the changed MIC The terminal voltage value (0.27V) is determined as the button voltage value.

Step 102, judging whether there is a corresponding relationship between the key voltage value and the photographing instruction, and if not, establishing a corresponding relationship between the key voltage value and the photographing instruction.

Exemplarily, due to differences in the specifications of various selfie sticks, the ground impedance of the MIC end of the headphone connector is different, generally ranging from several hundred ohms to several thousand ohms, resulting in that when the button on the selfie stick is pressed, The MIC terminal voltage value (button voltage value) read by the ADC is also different. Existing mobile devices are usually adapted to several common selfie sticks before leaving the factory, and a corresponding relationship is established between the key voltage values of these selfie sticks and the camera command. After the user inserts the earphone plug of the selfie stick into the mobile device, if the selfie stick inserted by the user at this time is a selfie stick that has been adapted before the mobile device leaves the factory, after pressing the button on the selfie stick, the button voltage value read by the ADC There will be a corresponding relationship with the camera command, and the camera command can be directly executed according to the corresponding relationship, such as reporting the key value to the upper layer, and the upper layer will continue to perform camera-related operations to realize the camera function; If it has not been adapted before, and it is judged that there is no corresponding relationship between the button voltage value and the camera command, then the corresponding relationship between the button voltage value and the camera command can be established. When the selfie stick is used again next time, it will be judged that there is a corresponding relationship between the key voltage value of the selfie stick and the photographing instruction, and the photographing instruction can be directly executed according to the corresponding relationship.

In the adaptation method of the selfie stick provided in Embodiment 1 of the present invention, after detecting that the earphone plug is inserted into the mobile device, if it is judged that the voltage value of the microphone terminal has changed, the changed voltage value of the microphone terminal is determined as the button voltage value; Whether there is a corresponding relationship between the key voltage value and the photographing instruction, if not, establish a corresponding relationship between the key voltage value and the photographing instruction. By adopting the above technical solution, when the user connects a selfie stick that has not been adapted before leaving the factory to the mobile device, the mobile device can automatically adapt by establishing the corresponding relationship between the button voltage value and the camera command. The selfie stick can be used normally, eliminating the troubles of users. In addition, after adopting the above technical solution, there is no need to release a new version to be compatible with the selfie stick that has not been adapted before leaving the factory, which can save the time and cost of releasing a new version.

On the basis of the above-mentioned embodiments, establishing the corresponding relationship between the key voltage value and the photographing instruction may specifically include: displaying the inquiry information of whether the selfie stick has been inserted; The corresponding relationship between the value and the camera instruction. Exemplarily, when the earphone plug inserted is not the earphone plug of the selfie stick, for example, the earphone plug of a wire-controlled earphone is inserted, when the volume key and other buttons on the wire-controlled earphone are pressed, the voltage value of the MIC terminal is also It will change, and the voltage value read by the ADC will not correspond to the camera command at this time. In order to avoid mistaking a part other than a selfie stick with a headphone plug for a selfie stick, an inquiry message whether the selfie stick is inserted can be displayed first, for example, "Selfie stick inserted? Yes/No" is displayed on the display screen of the mobile device, If the user clicks "Yes", it will be detected that the user triggers the confirmation operation that the selfie stick has been inserted, and then the corresponding relationship between the button voltage value and the camera command can be established. Of course, if the read MIC terminal voltage value has established a corresponding relationship with related operation commands such as volume adjustment in the mobile device, related operations can also be directly performed. At this time, the current working status of the mobile device needs to be considered, such as determining the When the device is currently playing music, you can directly perform related operations such as volume adjustment.
