The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110.

Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

[0051] The intelligent terminal 100 may further include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0052] although Figure 1 Not shown, the smart terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0053] To facilitate understanding of the embodiments of the present application, the communication network system on which the smart terminal of the present application is based is described below.

The LTE system includes a user equipment (UE) 201, an evolved UMTS terrestrial radio access network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) 202, an evolved packet core network (Evolved Packet Core, EPC) 203 and an operator's IP service 204 that are connected in communication in sequence.

[0055] Optionally, the user equipment 201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0056] The evolved UMTS terrestrial radio access network 202 includes an eNodeB 2021 and other eNodeBs 2022.

[0059] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new network systems (such as 5G), etc., without limitation here.

[0060] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0061] First embodiment See also Figure 3 , Figure 3 is a flow chart of the photographing method illustrated in this application. Figure 3 As shown, a shooting method of the present application comprises the steps of: S1: In response to a first scenario, a target lens motor in a target camera module is controlled to drive a target lens carrier to a base, and a control signal is maintained so that the target lens carrier continuously contacts the base.

[0062] Optionally, the first scenario in step S1 includes at least one of the following: Photographing or videotaping operations; The terminal is in a vibrating shooting scenario; The thrust applied to the target lens carrier is less than a preset threshold; The preview image of the target camera module contains water ripples.

[0063] To further explain, when a common digital camera shoots a scene with dense texture, strange water wave-like stripes often appear, which are called moiré. Moiré is a manifestation of the beat principle. Mathematically speaking, when two equal-amplitude sine waves with similar frequencies are superimposed, the amplitude of the synthesized signal will change according to the difference between the two frequencies. Usually, the cause of the water ripple phenomenon is the insufficient screen refresh rate. At the moment of taking a picture, some lines on the screen are not lit, resulting in a series of water ripples.

[0064] There are two ways to eliminate water ripples in the prior art. One is to use a fixed-focus module for shooting, and the other is to add a set of Hall sensors to sense the position of the lens through the Hall sensors before shooting. However, since the fixed-focus module uses a fixed-position lens, the relative displacement of the lens and the chip will not occur in high-acceleration scenes to keep the picture clear. Therefore, when the shooting target is beyond the focus clear range, the picture is blurred. The existing autofocus module uses a Hall sensor to sense the lens position. When the lens is not in the target position, the Hall sensor transmits a signal to the driver IC, and the driver IC controls the lens to move to the corresponding position, thereby taking a clear picture. However, adding a Hall sensor will increase the cost and expand the size. If a Hall sensor is added to the space of the existing equipment and its circuit is arranged, especially in the limited space of high-precision devices, it will increase the design difficulty. Compared with some existing designs, for example, a closed-loop AF (autofocus) motor is used, but the cost and size are increased, and a fixed-focus module is used, but the zoom cannot be used to shoot close objects, affecting the user experience. This embodiment improves the water ripple problem caused by the lens motor when shooting in a vibrating scene through a process without increasing the cost and size.

[0065] Further explanation, the study found that in some existing designs, see Figure 4 , Figure 4 This is a diagram of the structure of a conventional lens motor illustrated in this application.

[0066] The camera module includes: a shooting lens and a lens motor, the lens motor includes a base 11, a shell 12 covering the base and forming a chamber with the base, a driving device located in the chamber, a lens carrier 13, two elastic members 14, and a mounting seat 15, wherein the mounting seat 15 is arranged at the connection between the base 11 and the shell 12; the driving device is arranged between the lens carrier 13 and the shell 12, and is used to drive the lens carrier to move.

[0067] Specifically, the driving device includes a coil 16 and a magnet 17, the magnet 17 is arranged on the inner periphery of the housing 12, and the coil 16 is wound on the lens carrier 13. The two ends of the lens carrier 13 are respectively fixedly connected to the inner ring of the elastic member 14, the outer ring of one elastic member 14 is fixedly connected to the mounting seat 15, and the outer ring of the other elastic member 14 is connected to the housing. The outer end of the lens carrier 13 is fixedly connected to the shooting lens.

[0068] When the lens carrier 13 contacts the base 11, the connection between the elastic member 14 and the outer end of the lens carrier 13 is lower than the connection between the elastic member 14 and the housing 12, and the connection between the elastic member 14 and the inner end of the lens carrier 13 is lower than the connection between the elastic member 14 and the mounting seat 15. The elastic member 14 has a fixed elastic coefficient. If the pressure exceeds the elastic coefficient, plastic deformation will occur. When the lens motor is in a shooting scene with a large vibration acceleration, the vibration of the elastic member 14 will change from elastic deformation to plastic deformation. The elastic member 14 drives the lens carrier 13 to move during the vibration process, causing the shooting lens to shake during the shooting operation, thereby capturing a picture with water ripples.

[0069] Based on this, see Figure 5 , Figure 5 This is a diagram of the improved target lens motor structure shown in the example of the present application. This embodiment makes corresponding improvements to the existing lens motor to eliminate the water ripple phenomenon.

[0070] Optionally, in response to starting the anti-shake shooting mode, a preview image of the target camera module is obtained, and when water ripples appear on the preview image, the target lens carrier is driven to move to a preset position in the chamber to perform water ripple elimination processing on the preview image.

[0071] Optionally, the method for removing water ripples includes: determining a target shooting lens corresponding to the preview image, and driving a corresponding target lens carrier to move in the chamber according to the target shooting lens so that the carrier contacts a preset position in the chamber.

[0072] Optionally, the chamber comprises at least: a base on which the locking position is arranged; and a shell connected to the base. Further, the shell cover is arranged on the base and forms the chamber with the base, and the locking position is arranged on the base.

[0073] For example, a camera device is equipped with multiple camera modules, each of which includes a target shooting lens and a target lens motor. The target lens motor includes a base 11, a shell 12 covering the base and forming a chamber with the base, a driving device located in the chamber, a target lens carrier 13, and two elastic members 14; the driving device is arranged between the target lens carrier 13 and the shell 12, and is used to drive the target lens carrier 13 to move. The driving device includes a coil 16 and a magnet 17, the magnet 17 is arranged on the inner periphery of the shell 12, and the coil 16 is wound on the target lens carrier 13. The two ends of the target lens carrier 13 are fixedly connected to the inner ring of the elastic member 14 respectively, the outer ring of one elastic member 14 is fixedly connected to the base 11, and the outer ring of the other elastic member 14 is fixedly connected to the shell 12. The outer end of the target lens carrier 13 is fixedly connected to the target shooting lens.

[0074] It is further explained that the improved target lens motor cancels the mounting seat design and directly connects the elastic member 14 to the base 11. Moreover, when the target lens carrier 14 conflicts with the base 11, the connection between the elastic member 14 and the outer end of the target lens carrier 13 is higher than the connection between the elastic member 14 and the outer shell 12, and the connection between the elastic member 14 and the inner end of the target lens carrier 13 is higher than the connection between the elastic member and the base.

[0075] Optionally, the method for removing water ripples includes: determining a target shooting lens corresponding to the preview image, and driving a corresponding target carrier to move in the chamber according to the target shooting lens so that the carrier abuts against a locking position in the chamber.

[0076] In this embodiment, when the elastic member drives the target lens carrier to move during vibration, the target lens carrier will be pushed to the locking position. Considering that a camera device may be equipped with multiple camera modules, in this embodiment, the required target shooting lens is determined based on the focal length requirement of the current shooting, and then the corresponding target lens carrier is determined according to the target shooting lens.

[0077] How to keep the target lens carrier in a locked position, optionally, a shooting method, including: the motor thrust generated by the control signal is greater than the motor thrust in a conventional zoom situation.

[0078] Further, when the preset conditions are met, the electromagnetic force of the target lens motor is used to generate a reverse thrust so that the target lens carrier is kept against the preset position. The preset conditions include at least one of the following: being in a vibrating shooting scene; the thrust received by the target lens carrier is less than a preset threshold.

[0079] Optionally, when the target lens carrier in the target camera module contacts the base, the entire target camera module is in an optimal position for optical alignment.

[0080] When used in a vibration scene, the target shooting lens vibrates due to the internal vibration driving device or the vibration of the external vibration scene. Therefore, it is considered to use the force in the opposite direction to offset it to reduce the vibration amplitude. Further, the vibration force of the external vibration scene is in the vertical direction. Therefore, this embodiment can use the driving device to generate a pulling force in the opposite direction of the vertical direction. Therefore, this embodiment compares the thrust generated by the driving device with a preset threshold. If the thrust is less than the preset threshold, the electromagnetic force generated by the driving device is used to generate a thrust in the opposite direction, so as to ensure the stability of the position of the target shooting lens and ensure the stability of the picture of the shooting scene.

[0081] In one embodiment, if Figure 6 As shown, Figure 6 The improved camera terminal structure diagram shown in the present application. The camera terminal includes a display screen 500, a target lens motor, and a target camera lens 200, wherein the target lens motor includes: Base, housing, elastic member, control chip 100, PCB board, processing component, driving device 300, target lens carrier. The housing is covered on the base and forms a chamber with the base.

[0082] The control chip 100 is bonded to the PCB board, the processing components are bonded to the PCB board and the target lens carrier respectively, and the target lens carrier is bonded to the target shooting lens 200. The driving device includes a magnet and a coil, the magnet is fixedly bonded to the inner side of the shell, and the coil is wound on the target lens carrier. The target lens carrier is connected to the chamber through an elastic member, and shakes in the chamber under a vibration scenario. Based on this, in order to stop the target lens carrier from shaking, the present embodiment will move the target lens carrier to a locking position to limit and fix it, and then generate a reverse thrust through the electromagnetic force of the driving device to stop the target lens carrier from shaking.

[0083] The processing component includes an image processor 400, and the target shooting lens 200 has a built-in sensor. The control chip 100 is respectively connected to the target shooting lens 200, the image processor 400, and the driving device 300, receives the environmental data collected by the shooting lens 200, transmits the environmental data to the image processor 400, generates a shooting picture through the image processor 400, receives the shooting picture, and performs a preset analysis and judgment on the shooting picture to determine whether the current shooting operation requires focusing or switching lenses, controls the target shooting lens 200 to switch through the driving device 300, and performs focusing processing on the switched target shooting lens 200.

[0084] Further explanation: usually, the elastic member cannot move elastically without external force. However, the driving device in this embodiment will generate motor vibration during operation, which will drive the elastic member to move elastically; in addition, when the target lens motor is shooting in a vibrating scene, it will also drive the elastic member to move elastically. In other words, the elastic operation has at least two trigger sources, one is the internal working vibration of the driving device, and the other is the external vibration scene. Based on this, this embodiment suppresses the generation of water ripples by controlling the position of the target lens carrier in the vibration.

[0085] Optionally, the vibration displacement of the target shooting lens is controlled by controlling the vibration displacement of the target lens carrier. To further explain, the control chip controls the driving device to work and generate motor vibration after power is turned on. The driving device is driven to generate the maximum vibration amplitude to drive the target lens carrier to shift significantly. In this embodiment, when the control chip gives the driving device a maximum current in a preset range of a negative direction (NS), the motor vibration generated by the driving device drives the coil and the target lens carrier to the preset locking position of the chamber, that is, the preset fixed position. At this time, the coil, the target lens carrier and the target shooting lens cannot continue to move, and can only wait for the pulling force in the opposite direction to make the elastic member rebound.

[0086] The control chip uses AA (Active Alignment) technology to adjust OC, DA (die attach) tilt, LHA (lens Holder Attach) tilt, locking tilt, motor static tilt, and motor dynamic tilt to drive the lens to suppress vibration.

[0087] Optionally, the control chip energizes the driving device to control the driving device to work. Preferably, a preset current value is given to the driving device to control the driving device to drive the focus of the target shooting lens to a preset infinite position and then stop, that is, the lens of the lens is no longer rotated, and then AA adjustment is performed. At this time, the target lens carrier is abutted to the locking position, and the driving device drives the focus of the target shooting lens to rotate to the infinite position, thereby suppressing water ripples generated by the vibration of the target shooting lens.

[0088] Optionally, based on different types of drive devices, the height of the locking position is adjusted to compensate for the difference between the strokes of different drive devices.

[0089] In this embodiment, the target lens carrier is bonded to the target shooting lens, and the position of the target shooting lens is changed by the change of the spatial position of the target lens carrier during the vibration process.

[0090] Optionally, the target shooting lens includes at least one of the following: a wide-angle lens; a telephoto lens; a zoom lens; a fixed-focus lens.

[0091] Optionally, the target camera module includes at least one of the following: a main camera module; a wide-angle camera module; a telephoto camera module.

[0092] In one embodiment, the target shooting lens includes: a main lens, a wide-angle lens, and a telephoto lens. Different types of target shooting lenses are configured with different types of driving devices. The driving device can be a VCM motor. VCM (Voice Coil Motor), a voice coil motor in electronics, is a type of target lens motor. Because the principle is similar to that of a speaker, it is called a voice coil motor. It has the characteristics of high frequency response and high precision. The main principle is to control the stretching position of the spring sheet in a permanent magnetic field by changing the DC current of the coil in the target lens motor, thereby driving the up and down movement. The camera device uses a VCM motor to adjust the lens position to change the focal length so that the camera presents the clearest state. The size and vibration stroke of different types of driving devices may have certain differences. This embodiment compensates for the difference between the lower strokes of different driving devices by adjusting the locking height of the locking position.

Figure 8 As shown, a method for obtaining a preview screen of the present application includes the following steps: S201: Obtain the focal length of the current target shooting lens; S202: Switch the target shooting lens according to the focal length to obtain a preview image.

[0096] Optionally, when the target camera module is the main camera module, the target lens carrier is the main lens carrier; when the target camera module is the wide-angle camera module, the target lens carrier is the wide-angle lens carrier; when the target camera module is the telephoto camera module, the target lens carrier is the telephoto lens carrier.

[0097] Optionally, step S2 includes: S21: In response to the focusing operation in the first focal length range, maintaining the control signal so that the main lens carrier continues to contact the base, and scaling the preview image of the main camera module according to a second strategy.

[0099] S23: In response to a focusing operation greater than the maximum value of the first focal length range, maintaining a control signal so that the telephoto lens carrier continues to contact the base, switching to a preview screen of the telephoto camera module, and scaling the preview screen of the telephoto camera module according to a second strategy.

[0100] The second strategy includes at least one of the following: in response to a focus increase operation, enlarging the preview screen of the target camera module; in response to a focus decrease operation, reducing the preview screen of the target camera module.

When the preview screen of the wide-angle camera module is zoomed in, in response to the focus increasing operation, the preview screen of the wide-angle camera module is enlarged; in response to the focus decreasing operation, the preview screen of the wide-angle camera module is reduced.

[0103] Optionally, in response to starting the anti-shake shooting mode, the target lens motor is powered on and starts working, driving the main lens or the wide-angle lens or the telephoto lens to move to a preset position in the chamber, and keeping the target lens carrier continuously against the preset position.

[0104] Further, in response to the focal length being within the first focal length range, the main lens is controlled to trigger the anti-shake shooting mode, and the target lens carrier of the main lens is kept in contact with the preset position.
