As shown in fig. 1, the schematic diagram of the mid-mounted voice coil motor is shown, where the spring stroke of the mid-mounted voice coil motor is 0 at the middle position, the midpoint position is the stroke zero point of the mid-mounted voice coil motor, and no current is consumed when focusing is performed at the stroke zero point position of the mid-mounted voice coil motor. The zero-point of travel in fig. 1 corresponds to a Code value of 512 and a corresponding current of 0 mA.
The far focus position and the near focus position in the existing middle voice coil motor are generally located on two sides of the stroke zero point, that is, the spring stroke corresponding to the far focus position and the near focus position is located on two sides of 512 codes, for example: the spring stroke Code value corresponding to the far focus position is 650, and the spring stroke Code value corresponding to the near focus position is 350, which means that no matter the auto-focusing module is focusing at the near focus position or the far focus position, the current is required to drive the center voice coil motor to drag the lens module to move, and the power consumption is relatively high.

Since the resolving power is relatively less deteriorated and the three-posture difference is small when the focal position is close to the nonlinear region of the spring stroke of the center-set voice coil motor, and the second focus position is located in the nonlinear region of the spring stroke, the three-posture difference is small when focusing is performed at the second focus position.
In addition, the first focusing position is a near-focusing position; the second focus position is located in a nonlinear region of the mid-voice coil motor where a spring stroke Code value is less than 300.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
In view of the above, the present embodiment provides an auto-focusing method, which is applied to an imaging apparatus including a mid-mounted voice coil motor, and includes: determining a target focusing position according to the shooting requirement; if the target focusing position is a first focusing position, keeping the middle voice coil motor at a stroke zero point, wherein the first focusing position is one of a near focusing position or a far focusing position; if the target focusing position is not the first focusing position, the center voice coil motor is electrified to drive the lens module of the imaging device to move to the target focusing position.
Because the stroke starting point of the middle voice coil motor is located at the middle position, namely the stroke zero point, the default position of the middle voice coil motor before starting is located at the stroke zero point, and current does not need to be consumed when focusing is carried out at the stroke zero point of the middle voice coil motor. If the target focusing position is a first focusing position, the middle voice coil motor is kept at the stroke zero point, namely, current does not need to be consumed when focusing is carried out at the near-focusing position or the far-focusing position, and the first focusing position is one of the near-focusing position or the far-focusing position; if the target focusing position is not the first focusing position, the central voice coil motor is energized to drive the lens module to move to the target focusing position, and then current is consumed. Therefore, compared with the scheme that the current is required to drive the existing middle voice coil motor no matter the middle voice coil motor is focused at the near-focus position or the far-focus position, the current required by the middle voice coil motor during automatic focusing can be greatly reduced, and the power consumption is reduced.
The following describes the implementation details of the auto-focusing method of the present embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing the present embodiment.
The flow chart of the auto-focusing method in the present embodiment is shown in fig. 2:
step S11: and determining the focusing position of the target according to the shooting requirement.
Step S12: and judging whether the target focusing position is a first focusing position, wherein the first focusing position is one of a near focusing position or a far focusing position. If yes, the flow proceeds to step S13; if the determination is no, the process proceeds to step S14.
Step S13: and keeping the middle voice coil motor at the stroke zero point.
Step S14: the center voice coil motor is powered on to drive the lens module to move to the target focusing position.
Specifically, in the present embodiment, the first focus position is located at a stroke zero position of the center voice coil motor, and the first focus position is one of a near focus position and a far focus position. When the target focusing position is determined to be the first focusing position, the middle voice coil motor is kept at the stroke zero point, namely, the current does not need to be consumed when the focusing is carried out at the near-focusing position or the far-focusing position; if the target focusing position is not the first focusing position, the central voice coil motor is energized to drive the lens module to move to the target focusing position, and then current is consumed. Compared with the scheme that the current is required to drive the middle voice coil motor no matter the middle voice coil motor is focused at the near-focus position or the far-focus position, the current required by the middle voice coil motor during automatic focusing can be greatly reduced, and the power consumption is reduced.
Step S15: the three-attitude difference is compensated for the lens module by using the middle voice coil motor.
Specifically, the motor characteristic of the center voice coil motor can be divided into two regions, a linear region and a non-linear region, and the non-linear region is located on both sides of the linear region. The elastic sensitivity of the two areas is different, under the same acting force, the displacement of the linear area is large, the displacement of the nonlinear area is small, the displacement represents the defocusing degree of the lens module, and the larger the defocusing degree is, the worse the resolving power is.
The concept of three-attitude difference of the automatic focusing module is introduced, and because the lens module has certain weight, when the lens module is used at different pitch angles, the gravity of the lens module has a component force in the elastic direction of the middle voice coil motor, so that the lens module is out of focus, which is called as the three-attitude difference of the automatic focusing module. The spring stroke Code values corresponding to the far focus position and the near focus position of the existing mid-voice coil motor are on two sides of 512 codes, for example: the spring stroke Code value corresponding to the far focus position is 650, the spring stroke Code value corresponding to the near focus position is 350, and the far focus position and the near focus position are both located in the linear region of the middle voice coil motor.
When the automatic focusing module is used upwards, most of the position of the lens module is in a linear region when focusing is carried out at a far-focus position, and the lens module can possibly touch a nonlinear region; when focusing is carried out at a near-focus position, the position of the lens module is always in a linear region, the displacement of the middle voice coil motor is larger, the degradation of resolving power is relatively larger, and the difference of three postures is larger. When the automatic focusing module is used downwards, the position of the lens module is always in a linear region when focusing is carried out at a far-focus position, the displacement of the middle voice coil motor is larger, the degradation of resolving power is relatively larger, and the difference of three postures is smaller; most of the lens module positions are in a linear region when focusing is carried out at a near-focus position, a nonlinear region is possibly touched, the degradation of resolving power is relatively small, and the difference of three postures is small. It can be seen that the deterioration of the resolving power is relatively small and the difference of the three attitudes is small when the focus position is close to the nonlinear region, and the deterioration of the resolving power is relatively large and the difference of the three attitudes is large when the focus position is close to the linear region.
In order to compensate for the three-posture difference when focusing is performed at the first focus position, in this embodiment, the center voice coil motor is used to compensate for the three-posture difference for the lens module. Can realize, utilize to put voice coil motor in and compensate three attitude differences for the lens module, include: and controlling the central voice coil motor to focus for multiple times at the position close to the target focusing position.
After focusing at the first focus position, focus is sought a plurality of times adjacent to the target focus position. That is, the lens module moves toward the nonlinear region by searching for focus several times near the zero point of the stroke (e.g., 512 Code), so that the deterioration of the resolving power can be reduced, and the three-attitude difference can be reduced. For example: after focusing is carried out at a first focus position (for example, the corresponding spring stroke 512 Code), focusing is carried out again at the position of 514Code or 510 Code; alternatively, after focusing is performed at the first focus position (e.g., the corresponding spring stroke 512 Code), focusing is performed again at the position of 517Code or 507 Code.
In some examples, after determining the target focusing position according to the shooting requirement, the method further includes: if the target focusing position is a second focusing position, the central voice coil motor is powered on to drive the lens module to move to the second focusing position, and the second focusing position is the other one of the near focusing position and the far focusing position.
Realistically, for the central voice coil motor circular telegram in order to drive the lens module to move to the second focus position, include: the middle voice coil motor is electrified to drive the lens module to move to a second focusing position in a non-linear area of the spring stroke of the middle voice coil motor. In the present embodiment, the second focal position is located in the nonlinear region of the stroke of the center voice coil motor, and therefore, the difference in the three postures is small when focusing is performed at the second focal position.
In one particular embodiment, as shown in FIG. 3, the first focus position is a near focus position; the second focus position is located in a nonlinear region of the mid-voice coil motor where the spring stroke Code value is less than 300.
Specifically, the spring stroke Code value corresponding to the near focus position is 512, and for the center-set voice coil motor, the stroke is 0 at this time, the current is 0, and the power consumption is the lowest. The far focus position is located in a stroke nonlinear region of the mid-voice coil motor, for example, the spring stroke Code value corresponding to the second focus position is less than 300, so that the difference of three postures is small when the far focus position is focused.
In another specific embodiment, as shown in FIG. 4, the first focus position is a far focus position; the second focus position is located in a nonlinear region of the mid-voice coil motor where the spring stroke Code value is greater than 700.
Specifically, the spring stroke Code value corresponding to the telephoto position is 512, and for the center-set voice coil motor, the stroke is 0 at this time, the current is 0, and the power consumption is the lowest. The near focus position is located in a stroke nonlinear region of the mid-voice coil motor, for example, the spring stroke Code value corresponding to the second focus position is larger than 700, so that the difference of three postures is small when focusing is carried out at the near focus position.
It should be noted that, in practical applications, the first focal point is a near-focus position or a far-focus position, depending on the common application state, for example: in the WeChat payment equipment, two use scenes, namely palm brushing and face brushing, exist, wherein the application distance of the palm brushing is 10-20 cm, and the palm brushing belongs to near-focus use; the application distance of the brush face is 30-80 cm, and the brush face belongs to far focus use. When the device is in standby state, if the common application state is the palm brushing mode, the first focus position (for example: the corresponding spring stroke 512 Code) is set as the close focus position, and the power consumption is minimum; if the common application state is the face brushing mode, the power consumption is minimized by setting the first focal position (e.g., the corresponding spring stroke 512 Code) to the far focus position. Therefore, the first focal position can be determined to be the near focal position or the far focal position according to the focal position corresponding to the mode with the largest number of use times of the user by combining application scenes, so that the power consumption in the standby mode is ensured to be minimum, and the power consumption of the whole machine is reduced.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

That is, as can be understood by those skilled in the art, all or part of the steps in the method for implementing the embodiments described above may be implemented by a program instructing related hardware, where the program is stored in a storage medium and includes several instructions to enable a device (which may be a single chip, a chip, or the like) or a processor (processor) to execute all or part of the steps of the method described in the embodiments of the present application. And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk or an optical disk, and other various media capable of storing program codes.
