For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The electronic equipment provided by the embodiment of the invention can be a mobile phone, a tablet personal computer, intelligent wearable equipment and the like, and generally comprises a camera module.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a camera module according to an embodiment of the present invention, where the camera module 10 includes a lens 11, a camera motor 12, and a driver 13. The camera module 10 may be disposed on a circuit board 20 of the electronic device, and the circuit board 20 may be a Flexible Printed Circuit (FPC) and is connected to a main board of the electronic device through a btb (board to board). In addition, the camera module 10 may further include other components such as a light sensor and a flash lamp, or may be a multifunctional module formed by combining with other modules such as a headphone, which will not be described herein.
The lens 11 is fixed in the camera motor 12, and can move up and down in the camera motor 12 under the driving of the driver 13 to adjust the focal length of the camera module 10.
The camera motor 12 may be a mechanical motor, an electronic touch motor, a ring-shaped ultrasonic motor, etc., which is not limited herein. Alternatively, in one embodiment, a voice coil motor may be used to achieve the position adjustment of the lens 11. A Voice Coil Motor (Voice Coil activator/Voice Coil Motor) is a device that converts electrical energy into mechanical energy and realizes linear and limited swing motion.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a camera motor in an embodiment of the camera module provided by the present invention, in which the camera motor 12 includes a magnetic shield 121, a magnet 122, an upper elastic sheet 123, a lens carrier 124, a motor coil 125, a lower elastic sheet 126, and a motor base 127. Wherein, the lens 11 is fixed on the lens carrier 124; the actuator 13 is specifically configured to obtain a driving command to control the current intensity in the coil 125, thereby controlling the movement of the lens carrier 124 in the voice coil motor.
The working principle of the voice coil motor is as follows: in a permanent magnetic field formed by the magnet 122, the extension position of the spring piece (i.e. the upper spring piece 123 and the lower spring piece 126) is controlled by changing the direct current of the motor coil 125 in the motor, so as to drive the lens carrier 124 to move back and forth, further drive the lens 11 to move back and forth, and further realize the zoom shooting of the camera.
The driving instruction received by the driver 13 specifically indicates that when the application currently running in the electronic device includes a preset application, the lens carrier 124 is controlled to be attached to the motor mount 127 or away from the motor mount 127 to a set position.
It can be understood that, since the lens carrier 124 is movable, when the camera module 10 is vibrated by external vibration, the lens carrier 124 moves in the camera motor 12 and easily hits the motor base 127 or the inner wall of the camera motor 12, which may damage the lens 11.
Specifically, when the frequency of the external vibration is consistent with the natural frequency of the camera motor 12, the vibration is particularly strong, and the damage to the lens 11 is also strongest, so that the driving instruction received by the driver 13 in this embodiment specifically indicates that the lens carrier 124 is controlled to be close to the motor base 127 or away from the motor base 127 to a set position when the application currently running in the electronic device includes a preset application. The preset application is an application in which the vibration generated during operation is consistent with the natural frequency of the camera motor 12.
The following describes a control method of the camera module by several embodiments, wherein reference may be made to fig. 2 for the description of the structure of the lens carrier, the motor base, and the like and the position thereof.
Referring to fig. 3, fig. 3 is a schematic flow chart of a first embodiment of a control method of a camera module provided by the present invention, the method including:
step 31: and acquiring the application program currently operated by the electronic equipment.
Optionally, in this embodiment, the camera module may be a camera module installed on an electronic device, for example, a front camera or a rear camera of a mobile phone. The electronic device has an application program installed therein. Continuing with the cell phone example, the installed applications may include chat-type applications, audio-type applications, video-type applications, and game-type applications. It is to be understood that the application program in the present embodiment is generally an application program having sound or vibration played out.
Specifically, the audio application is taken as an example, and can be a music playing application program, and when the application program runs, audio information is played out through a loudspeaker of the electronic equipment, and meanwhile vibration of the electronic equipment can be caused; taking the chat application as an example, the chat application can remind the user by vibrating the electronic device when receiving the message. Both of the above two methods cause vibration of the mobile phone, and if the vibration frequency is consistent with the natural frequency of the camera motor or the vibration amplitude is greater than a certain degree, resonance is caused, and the lens is damaged.
Step 32: and judging whether the currently running application program comprises a preset application program.
It can be understood that, since the lens damage caused by the resonance of the electronic device and the camera motor is the most serious, it is necessary to determine whether the vibration frequency caused by the application program during running is consistent with the natural frequency of the camera motor or whether the amplitude of the vibration is greater than the set value.
In this embodiment, all the application programs in the electronic device may be classified in advance, and the application degree in which the vibration frequency caused by the operation is consistent with the natural frequency of the camera motor or the amplitude of the vibration is greater than the set value may be defined as the preset application program.
If the determination result in step 32 is yes, step 33 is executed, and if the determination result in step 32 is no, the lens carrier is not moved.
Step 33: and controlling the lens carrier to be tightly attached to the motor base or be far away from the motor base to a set position.
On one hand, when the lens carrier and the motor base are tightly attached together, the lens carrier and the motor base are fixed together, and even if vibration occurs outside, the relative positions of the three are difficult to change, so that the lens cannot collide with the motor base.
On the other hand, when the lens carrier and the motor base are far apart, even if the lens carrier is displaced due to vibration from the outside, the small amplitude position due to the vibration does not cause the lens to hit the motor base because the distance between the lens carrier and the motor base is long.
Different from the prior art, the control method of the camera module in the embodiment includes: acquiring an application program currently operated by the electronic equipment; judging whether the currently running application program comprises a preset application program or not; if so, the lens carrier is controlled to be tightly attached to the motor base or be far away from the motor base to a set position. Through the mode, when the vibration is caused by running the application program outside, the lens cannot collide with the motor base or the side wall, on one hand, the lens is protected from being damaged, and on the other hand, abnormal sound cannot be emitted due to the collision between the lens and the motor to influence the running of the external application program.
The following describes the vibration frequency and the vibration intensity caused by the application program.
Referring to fig. 4, fig. 4 is a schematic flow chart of a second embodiment of a control method of a camera module provided by the present invention, the method including:
step 41: and acquiring the vibration frequency of the electronic equipment when each application program runs.
Step 42: and judging whether the vibration frequency is in a preset frequency range.
Wherein the preset frequency range can be set according to the natural frequency of the camera motor. For example, the frequency range may be set by plus or minus 200Hz on the basis of the camera motor natural frequency. Specifically, in one embodiment, the frequency range is 500 and 800 Hz.
When the determination result of step 42 is yes, step 43 is executed.
Step 43: the application is added to the blacklist.
It will be appreciated that steps 41-43 may be performed only once, i.e. the determination and blacklisting operations are performed on the first run of each application, while the following steps are performed directly on the second run.
Step 44: and acquiring the application program currently operated by the electronic equipment.
Step 45: and judging whether the currently running application programs are the application programs in the blacklist or not.
If the determination result in step 45 is yes, step 46 is executed.
Step 46: and controlling the lens carrier to be tightly attached to the motor base or be far away from the motor base to a set position.
It can be understood that, in this embodiment, by adding the application program whose vibration frequency meets the requirement to the blacklist in advance, when the application program runs, it is only necessary to directly determine whether the application program is an application program in the blacklist.
Referring to fig. 5, fig. 5 is a schematic flow chart of a third embodiment of a method for controlling a camera module according to the present invention, the method including:
step 51: and acquiring the vibration intensity of the electronic equipment when each application program runs.
Step 52: and judging whether the vibration intensity is greater than a preset intensity value or not.
If the determination result in step 52 is yes, step 53 is executed.
In step 52, the judgment of the vibration intensity may specifically judge the volume of the electronic device when the application program is running.
It can be understood that the volume directly affects the vibration strength of the electronic device, i.e. the vibration amplitude. For example, music playing applications are typically louder, while chat applications are typically louder.
Optionally, in a specific embodiment, it may be determined whether the volume of the application program in operation is greater than a preset volume value, where the preset volume value may be 80% of the total volume of the electronic device.
The volume of the loudspeaker of the electronic equipment can be obtained as a judgment basis. Taking a mobile phone as an example, when a user uses the mobile phone to run an application program, the user usually adjusts a fixed volume as a default volume, and when the user feels that the volume is inappropriate, the user performs corresponding adjustment. For example, the total volume of the handset is 20, and the default volume set by the user is 10.
In the present embodiment, the setting condition may be set such that the sound volume is greater than or equal to 16.
Step 53: the application is added to the blacklist.
It will be appreciated that steps 51-53 may be performed only once, i.e. the determination and blacklisting operations are performed on the first run of each application, while on the second run the following steps are performed directly.
Step 54: and acquiring the application program currently operated by the electronic equipment.
Step 55: and judging whether the currently running application programs are the application programs in the blacklist or not.
If the determination result in step 55 is yes, step 56 is executed.
Step 56: and controlling the lens carrier to be tightly attached to the motor base or be far away from the motor base to a set position.
It can be understood that, in this embodiment, by adding the application program whose vibration intensity meets the requirement to the blacklist in advance, when the application program runs, it is only necessary to directly determine whether the application program is an application program in the blacklist.
The following describes how to control the movement of the lens mount in detail through several embodiments.
Referring to fig. 6, fig. 6 is a schematic flow chart of a fourth embodiment of a method for controlling a camera module according to the present invention, the method including:
step 61: and acquiring the application program currently operated by the electronic equipment.
Step 62: and judging whether the currently running application program comprises a preset application program.
If the determination result in step 62 is yes, step 63 or step 64 is executed.
And step 63: and introducing a driving current in a first direction to the motor coil so as to enable the lens carrier to be far away from the motor base to a set position.
Step 64: and driving current in a second direction is introduced to the motor coil so that the lens carrier is tightly attached to the motor base.
Wherein the first direction drive current and the second direction drive current have opposite current directions.
After step 63 or step 64 is performed, step 65 is performed.
Step 65: and judging whether a preset application program in the currently running application programs is closed or not.
If the determination result in step 65 is yes, step 66 is executed.
And step 66: and controlling the camera motor to be powered off.
Also in conjunction with fig. 7, in an embodiment, there is provided a method for determining a first direction driving current and a second direction driving current, the method comprising:
step 71: a first distance between the motor mount and the set position is determined, and a maximum current value to move the lens carrier from the motor mount to the set position is determined.
Step 72: a second distance between the current position of the lens carrier and the motor mount is determined.
Step 73: and determining the magnitude of the first direction driving current or the second direction driving current according to the ratio of the second distance to the first distance and the maximum current value.
Referring to fig. 8 again, the first distance between the motor mount and the set position is d1, the maximum current value for moving the lens carrier from the motor mount to the set position is I, and the second distance between the current position of the lens carrier and the motor mount is d 2.
Wherein the magnitude of the first direction driving current may be determined using the following formula:
Determining the magnitude of the second direction drive current using the following equation:
different from the prior art, the displacement of the lens carrier is adjusted by changing the current of the motor coil in the embodiment, the structure of the camera module or the electronic device does not need to be improved, only the program executed by the controller of the camera module needs to be improved, and therefore the driving current of the motor coil is adjusted according to the running condition of the application program, when the running application program meets the set condition, the movement of the lens is controlled, the lens impact caused by vibration is avoided, on one hand, the lens is protected from being damaged, and on the other hand, the abnormal sound cannot be emitted due to the impact of the lens and the motor to influence the running of the external application program.
Referring to fig. 9, fig. 9 is a schematic flow chart of a fifth embodiment of a method for controlling a camera module according to the present invention, the method including:
step 91: and judging whether the camera module works.
It can be understood that, when the camera module is in operation, the distance between the lens carrier and the motor base is controlled by the driving current to adjust the focal length, so that even if there is vibration, the lens is not affected, and the lens and the motor are not collided. The embodiment is mainly applied to the situation that when the camera module does not work, namely when the motor is not electrified, the lens carrier is not controlled by the driving current, and can move when the vibration is strong.
And step 92: the method comprises the steps of obtaining an application program which starts a play-out mode or a vibration mode in the application programs currently running in the electronic equipment.
It will be appreciated that an application program, when running, typically includes at least three modes, a play mode, a vibrate mode and a mute mode. The camera module comprises a camera module, a sound module, a vibration module and an application program, wherein the camera module is arranged in the sound module, the sound module is arranged in the sound module, and the vibration module is arranged in the sound module.
Step 93: and judging whether the application programs of the open external mode or the vibration mode comprise preset application programs.
If the determination result in step 93 is yes, step 94 is executed.
Step 94: and controlling the lens carrier to be tightly attached to the motor base or be far away from the motor base to a set position.
In this embodiment, whether through detecting the camera work and whether the detection application can sound and vibration when the operation, avoid just carrying out the regulation of camera module as long as set for the application operation, increased more qualification in this implementation for the judgement condition to camera motor regulation is harsher, is favorable to reducing electronic equipment's consumption.
