As will be understood by those skilled in the art, the mobile terminal herein refers to an electronic device with an optical anti-shake function, such as a smart phone and a tablet computer.

Referring to fig. 1, an embodiment of the present invention provides a distribution method of a motion signal, where the motion signal is collected by a gyroscope disposed in a camera module of a mobile terminal, and the method includes:

s1, the processor of the mobile terminal acquires the type of the currently running application program, wherein the running of the application program needs to utilize the motion signal;

s2, acquiring a motion signal acquired by a gyroscope according to the type of the application program; and/or sending a control command to the gyroscope, and controlling the gyroscope to send the acquired motion signal to the optical anti-shake module of the mobile terminal.

As described in step S1, the motion signal is an angle, acceleration, or other signal collected by the gyroscope. The operation of the application program needs to use the motion signal, that is, the application program can be normally used only by the motion signal collected by the gyroscope. The mobile terminal comprises a game application program which generally comprises a game operation by utilizing a motion signal acquired by a gyroscope, namely the application program which controls a certain setting in the application program by performing operations such as inclination, movement and the like of different angles on the mobile terminal; also includes motion application program for analyzing human motion data based on the motion signal, such as step counting application program; the camera module is further provided with a shooting application program and the like for carrying out optical anti-shake processing on the camera module according to the motion signal.

As described in the above step S2, the motion signals required by different types of applications, such as game-type and sports-type applications, are generally controlled by the processor, so the motion signals are obtained by the way that the applications request the motion signals from the processor, and the processor directly obtains the motion signals collected by the gyroscope for the applications. And the shooting application program and the processor send control commands to enable the motion signals collected by the gyroscope to be directly sent to the optical anti-shake module for the optical anti-shake module to perform optical anti-shake processing.

Referring to fig. 2, in this embodiment, before the step of acquiring the type of the currently running application program by the processor of the mobile terminal, the method includes:

s101, judging whether the motion signal is needed for the running of the application program;

and S102, if so, supplying power to the gyroscope through a power supply circuit.

As described in steps S101 and S102, the power supply circuit is generally a power supply circuit disposed on a motherboard of the mobile terminal, and is connected to a power supply pin of the gyroscope, and the power supply circuit is generally controlled by the processor. If the running application program does not need the motion signal, the processor controls the power supply circuit to stop supplying power to the gyroscope so as to save the consumption of electric energy.

In this embodiment, after the step S102 of supplying power to the gyroscope through the power supply circuit, the method includes:

s103, acquiring a motion signal of the mobile terminal at a first placing angle;

s104, matching the motion signal with a calibration motion signal;

and S105, if the motion signal is successfully matched with the calibration motion signal, judging that the gyroscope works normally.

As described in the foregoing steps S103, S104, and S105, the first placing angle is a preset placing angle, for example, the mobile terminal is a mobile phone, and the upward horizontal plane of the screen of the mobile phone is set as the first placing angle. If the mobile phone is set according to the first placing angle, the motion signal collected by the gyroscope is generally a designated angle value. And matching the specified angle value with a preset calibration motion signal, and if the matching is successful, judging that the gyroscope works normally. The matching process generally includes comparing the specified angle value with the calibration motion signal, and if the degree of identity between the specified angle value and the calibration motion signal is higher than a specified percentage, the matching is determined to be successful. For example, when the recognition degree of the two signals is higher than 95%, the motion signal is successfully matched with the calibration motion signal, which indicates that the gyroscope can normally work. In other embodiments, a second placing angle, a third placing angle, and the like may be set, and the process of matching with the corresponding second calibration motion signal and the third standard motion signal may be performed, respectively, and if all matching is successful, it is determined that the gyroscope is working normally. Whether the gyroscope works normally or not is judged in advance, so that a user can select whether to run the application program or not, and adverse effects caused by directly running the application program are avoided, for example, when a certain game is in a certain key level when running last time, the user actively logs off, and must pass when logging on again, if the gyroscope fails to work when logging on again, the user can select not to log in the game, and the problem that the gyroscope fails to pass the pass due to the failure of the gyroscope is avoided.

In this embodiment, after the step S104 of matching the motion signal with the calibration motion signal, the method includes:

and S106, if the motion signal is not matched with the calibration motion signal, calibrating the gyroscope according to a preset rule.

As described in the step S106, the preset rule calibrates the gyroscope, and the process generally includes placing the mobile terminal according to a plurality of preset placing angles, inputting a calibration value every time one angle is placed, obtaining a confirmation command after all placing angles are placed and corresponding calibration values are input, and then calibrating according to a calibration formula, so that a calibrated gyroscope can be obtained, and the calibrated gyroscope can normally acquire a motion signal. In this embodiment, if the motion signal and the calibration motion signal still fail to match when the steps S103 to S106 are performed again after the gyroscope is calibrated, it may be determined that the gyroscope is damaged and needs to be replaced. The calibration formula is generally set according to a gyroscope, for example, if the angular change of the gyroscope is a linear change, a linear formula may be preset, and then calibration and the like may be performed according to the linear formula and the calibration value input by the linear formula.

In this embodiment, a standby gyroscope is arranged in the camera module; after the step S104 of matching the motion signal with the calibration motion signal, the method includes:

and S107, if the motion signal is not matched with the calibration motion signal, starting the standby gyroscope, and acquiring the motion signal through the standby gyroscope.

As described in step S107, the standby gyroscope is a gyroscope that is not used at ordinary times, and is started only when the gyroscope fails, so as to prolong the service life of the mobile terminal.

Referring to fig. 3, in this embodiment, the motion signal acquired by the gyroscope is acquired according to the type of the application program; and/or, before step S2 of sending a control command to the gyroscope, and controlling the gyroscope to send the collected motion signal to the optical anti-shake module of the mobile terminal, the method includes:

s201, searching a gyroscope sensitivity value corresponding to the application program in a preset sensitivity list;

and S202, controlling the sensitivity and the measuring range of the motion signal acquired by the gyroscope according to the sensitivity value of the gyroscope.

As described in steps S201 and S202, the gyroscope has a plurality of acquisition sensitivities, and the higher the acquisition sensitivity is, the smaller the corresponding range is, and conversely, the larger the range is. The Sensitivity (Sensitivity) refers to the degree of change in response of a method to a change in unit concentration or unit amount of a substance to be measured, and can be described by the ratio of the response or other indicator of the instrument to the concentration or amount of the corresponding substance to be measured. The range is the difference between the two extremes of the nominal range of the gyroscope. In this embodiment, the acquisition sensitivities required by different applications are different, for example, if the requirements on the acquisition sensitivity of a game application are not high, a relatively high range, a relatively low acquisition sensitivity, and the like are selected; the shooting-type application, because of the need for optical anti-shake, needs to choose a relatively high acquisition sensitivity without using a large range. In this embodiment, according to a specific application program, the corresponding sensitivity and range are selected, for example, the application programs of the two games are gun battle games and drag racing games, respectively, so that when the gun battle games are operated, a relatively high acquisition sensitivity is selected, and the drag racing games can select a relatively low acquisition sensitivity.

s203, searching a motion signal acquisition frequency value corresponding to the application program in a preset acquisition frequency list;

and S204, controlling the acquisition frequency of the motion signal acquired by the gyroscope according to the motion signal acquisition frequency value.

As described in steps S203 and S204, the collection frequency of the motion signals is the number of the motion signals collected in a predetermined time. In this embodiment, the acquisition frequencies required by different applications are different, for example, if the requirement for the acquisition frequency is high for a game application, a relatively high acquisition frequency is selected; for shooting type application programs, because optical anti-shake is needed, a relatively high acquisition frequency needs to be selected; and if the requirement on the acquisition frequency of the motion application program is low, selecting a relatively low acquisition frequency and the like to reduce energy consumption. In this embodiment, according to a specific application program, the corresponding acquisition frequency is selected, which not only can improve the operation quality of the application program, but also can effectively reduce the energy consumption of the mobile terminal.

In a specific embodiment, the mobile terminal is a smart phone, the smart phone is provided with an optical anti-shake module and a camera module, and the camera module is provided with a gyroscope. Before the gyroscope is used, whether the currently running application program needs to use the motion signal or not is judged, if yes, the gyroscope is powered through a power supply circuit, and the gyroscope is started. After the gyroscope is started, whether the gyroscope fails or not is judged through a preset detection step, if so, recalibration is carried out, or a standby gyroscope is started, and if not, the gyroscope is normally used. When the application program is operated, the type of the application program is judged firstly, if the type of the application program is a shooting type application program, the processor on the mainboard of the mobile terminal controls the gyroscope to send the collected motion signal to the optical anti-shake module, and other application programs which do not need optical anti-shake directly acquire the motion signal collected by the gyroscope through the processor. And when the gyroscope collects the motion signal, the specified sensitivity, collection frequency and the like can be selected according to a specific application program.

According to the distribution method of the motion signal, the gyroscope is arranged on the camera module, the gyroscope is closer to the shaking angle of the camera, and the effect is better during optical anti-shaking processing. Moreover, the gyroscope is arranged on the camera module, the influence of heat generated by the mainboard in work engineering does not need to be considered, and the accuracy of acquiring motion signals by the gyroscope is further improved. The gyroscope is not required to be arranged on the main board at the middle and high end of the movement, the gyroscope in the camera module is directly adopted to collect movement signals, and the movement signals can be selected to be sent to the processor or the optical anti-shake module according to the type of the application program currently running on the mobile terminal. The gyroscope arranged in the camera module is directly used for acquiring motion data, and the gyroscope does not need to be arranged on the main board, so that the cost is saved; the distribution method of the motion signal is simple and effective.
