Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are only a subset of the embodiments of the present disclosure, and not all embodiments. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
In the related art, lens switching or lens lifting of the terminal is often driven by a driving motor. The driving motor generally employs a voice coil motor, and the voice coil motor drives the lens to switch or move up and down by using a permanent magnetic field of a magnet and a lorentz force generated by an energized coil. The lens may be fixed by an elastic member (e.g., a spring). When the lens is required to be used (such as focusing and the like), the spring is controlled by the driving motor to deform, and the lens is driven to a preset position. When the current lens is not needed to be used, the terminal exits the current lens or switches other lenses different from the current lens, so that the current lens is powered off. When the current lens is powered off, the current lens rebounds from the current position to the process that the spring does not have a deformation position under the action of the spring tension, and the sound of lens impact can be emitted. When the lens is rebounded, if the generated lens impact sound is too large, the experience of a user in the using process is influenced. Taking the elastic member as a spring as an example, the connection relationship between the lens and the spring can be shown in fig. 1. It is understood that the process of powering down and rebounding the lens in the embodiment of the present disclosure may be understood as a process of powering down the lens and moving from the current usage position to a position where the elastic member (e.g., a spring) is not deformed. In the related art, in order to solve the above problem, in the process of powering off the current lens, the power is usually not immediately turned off, but the lens is slowly moved to a position where an elastic member (e.g., a spring) has no physical displacement, and then the power is turned off. It should be noted that if the rebound speed is slow during the lens moving or switching process, a feeling of lens response slowness is presented to the user.
The utility model provides a pair of camera lens adjusting device can be through the rebound speed of adjustment controlling means automatic adjustment camera lens based on the decibel value of camera lens striking sound to the rebound speed of messenger's adjustment back camera lens all satisfies user's requirement with the camera lens striking sound decibel value that produces when rebounding according to the rebound speed of adjustment back camera lens. Therefore, the design cost and the material selection cost can be reduced, the adjusting control device automatically adjusts the rebound speed of the lens, debugging personnel do not need to continuously modify codes, and the workload of the debugging personnel can be reduced.
A first aspect of the embodiments of the present disclosure provides a lens adjustment apparatus.
Fig. 2 is a view illustrating a lens adjusting apparatus according to an exemplary embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 2, the lens adjusting apparatus 100 includes a sound detecting apparatus 101, a data transmitting apparatus 102, and an adjustment control apparatus 103, and each apparatus and a connection relationship between each apparatus will be described below.
The sound detection device 101 may be configured to determine a lens impact sound generated when the lens is powered down and rebounded, and determine a decibel value of the lens impact sound. It is understood that the lens may be a lens in a lens module of the terminal 104. When the terminal 104 exits the current lens or switches different lenses, in the process that the current lens rebounds to the position where the spring does not deform under the action of the tension of the spring, a lens impact sound is emitted, and the emitted lens impact sound is the lens impact sound generated when the lens rebounds. In an example, the sound detection device 101 may collect and determine a decibel value for a lens impact sound. The sound detection device 101 may be a decibel test device, or may be another device that can determine the decibel of sound, and in this disclosure, the sound detection device 101 is not specifically limited.
The data transmission device 102 may be configured to transmit the decibel value of the lens impact sound determined by the sound detection device 101 to the adjustment control device 103, and transmit the rebound speed determined by the adjustment control device 103 to the lens. In one embodiment, the data transmission device 102 may be a Universal Serial Bus (USB) transmission line.
In one embodiment, the rebound velocity determined by the adjustment control device 103 can also be transmitted to the terminal 104, wherein the lens is disposed on the terminal 104. During application, the terminal 104 may control the rebound speed of the lens through a control component of the lens rebound. In one example, the control component that controls the lens bounce can be a processing chip of the terminal 104. The processing chip can send an instruction to the lens and control the rebound speed of the lens based on the instruction.
It can be understood that, since the lens moves a fixed distance in the process of rebounding to the position where the spring is not deformed under the action of the tensile force of the spring, the time consumed by the lens in the rebounding process (the time consumed by the user in the process of exiting or switching the lens) is influenced and is determined by the rebounding speed of the lens in the rebounding process.
In one embodiment, the data transfer device 102 may include a first universal serial bus and a second universal serial bus. The first usb is used to connect the sound detection device 101 and the adjustment control device 103. The second universal serial bus is used to connect the adjustment control device 103 and the control means for controlling the lens rebound.
The adjustment control device 103 may be configured to adjust the rebound speed of the lens based on a decibel value of a lens impact sound.
In an embodiment, the adjusting control device 103 may automatically adjust the rebound speed of the lens based on the decibel value of the lens impact sound determined by the sound detection device 101 until the rebound speed of the lens and the decibel value of the lens impact sound generated when the lens rebounds according to the adjusted rebound speed of the lens meet the requirements of the user. That is, the rebound speed of the lens does not make the user feel that the lens is insensitive, and the decibel value of the impact sound of the lens does not make the user feel that the lens is damaged. In one example, the tuning control device 103 may be a computer with analysis control software installed thereon.
The lens adjusting device provided by the present disclosure detects a lens impact sound generated when a lens rebounds through the sound detecting device 101, determines a decibel value of the lens impact sound, and transmits the decibel value of the lens impact sound to the adjustment control device 103. The adjustment control device 103 automatically adjusts the rebound speed of the lens based on the decibel value of the lens impact sound, so that the rebound speed of the adjusted lens and the decibel value of the lens impact sound generated when rebounding according to the rebound speed of the adjusted lens both meet the requirements of the user. Because the adjusting and controlling device 103 automatically adjusts the rebound speed of the lens, the design cost and the material selecting cost can be reduced, and debugging personnel do not need to continuously modify codes to realize the adjustment, so that the workload of the debugging personnel can be reduced.
The present disclosure will explain another lens adjusting apparatus by the following embodiments.
Fig. 3 is another lens adjusting apparatus according to an exemplary embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 3, the lens adjusting apparatus 200 may further include a housing part 204.
In one example, the housing part 204 may have an accommodating space to accommodate a lens, and an opening to place the sound detection device 201.
In one example, since the lens is disposed on the terminal 205, the terminal 205 can be placed in the accommodating space of the housing member 204, so that the lens impact sound generated by the lens of the terminal 205 during the rebound process is not interfered by the noise outside the housing member 204, and the decibel value of the lens impact sound determined by the sound detection device 201 is more accurate and reliable.
In one embodiment, the sound detection device 201 may be disposed at an opening opened in the housing member 204. The size of the opening formed in the housing component 204 can be matched with the size of the sound detection device 201, so that noise outside the housing component 204 cannot enter the accommodating space of the housing component 204 through the opening, and interference on the sound detection device 201 when the decibel value of the lens impact sound is determined is avoided. It can be understood that the housing component 204 also needs to be provided with a small hole for allowing the data transmission device 202 connecting the terminal 205 and the adjustment control device 203 to pass through, so as to ensure that the adjustment control device 203 can transmit the adjusted rebound speed to the terminal 205 or the lens, and further control the terminal 205 or the lens to adjust the rebound speed during the rebound process.
In another embodiment, the sound detection device 201 and the terminal 205 can be placed in the accommodating space of the housing component 204, so as to ensure that the sound detection device 201 is free from noise outside the housing component 204 during the process of determining the decibel value of the lens impact sound.
Further, the housing part 204 needs to be provided with a small hole for allowing the data transmission device 202 (first universal serial bus) connecting the sound detection device 201 and the adjustment control device 203 to pass through; and a small hole for allowing the data transmission device 202 (second universal serial bus) connecting the terminal 205 and the adjustment control device 203 to pass through.
Through this embodiment, the decibel value of the impact sound of the lens can be more accurately determined, and the rebound speed of the lens is automatically adjusted based on the determined decibel value of the impact sound of the lens, so that the rebound speed of the lens after adjustment and the decibel value of the impact sound of the lens generated when rebounding according to the rebound speed of the lens after adjustment more accurately meet the requirements of users.
Based on the same concept, a second aspect of the embodiments of the present disclosure also provides a lens adjustment method.
Fig. 4 is a flowchart illustrating a lens adjustment method according to an exemplary embodiment.
In an exemplary embodiment, as shown in fig. 4, the lens adjusting method may be applied to a lens adjusting apparatus according to the first aspect of the disclosed embodiment, wherein the lens adjusting apparatus may include a sound detecting apparatus. The lens adjustment method may include steps S11 and S12, which will be described separately below.
In step S11, the decibel value of the lens impact sound determined by the sound detection device is acquired.
In step S12, the rebound velocity of the lens is adjusted based on the decibel value of the lens impact sound.
In the application process, the current rebound speed of the lens may correspond to a decibel value of a lens impact sound generated when the lens rebounds according to the current rebound speed. The rebound speed of the lens and the decibel value of the impact sound of the lens influence the visual experience of a user, and further influence the experience of the user in the using process, so that the rebound speed of the lens can be automatically adjusted by the lens adjusting method, and the rebound speed of the adjusted lens and the decibel value of the impact sound of the lens generated when the adjusted rebound speed of the lens rebounds meet the requirements of the user.
In one example, a decibel value of a lens impact sound determined by the sound detection device may be obtained, and the rebound speed of the lens may be automatically adjusted based on the determined decibel value of the lens impact sound. In an embodiment, if the decibel value of the lens impact sound is greater than the preset threshold, the decibel value of the lens impact sound generated when the lens rebounds can be reduced by reducing the rebound speed of the lens, so that the decibel value of the lens impact sound does not exceed the tolerance limit of a user. In another embodiment, if the decibel value of the impact sound of the lens is smaller than the preset threshold (corresponding to the rebound speed of the lens felt by the user being too small), the rebound speed of the lens can be increased so that the lens is not considered by the user to be too sluggish in response to the lens when rebounding.
According to the lens adjusting method, the decibel value of the lens impact sound determined by the sound detection device is obtained, and the rebound speed of the lens is automatically adjusted based on the decibel value of the lens impact sound, so that the rebound speed of the adjusted lens and the decibel value of the lens impact sound generated when the adjusted lens rebounds according to the rebound speed meet the requirements of a user. The rebound speed of the lens can be automatically adjusted based on the method, so that the design cost and the material selection cost can be reduced, debugging personnel do not need to continuously modify codes to realize the rebound speed, and the workload of the debugging personnel can be reduced.
The present disclosure will explain a process of adjusting the rebound speed of the lens based on the decibel value of the lens impact sound by the following embodiments.
In an exemplary embodiment of the disclosure, if the decibel value of the lens impact sound is greater than the first sound decibel threshold, the rebound speed of the lens is reduced until the decibel value of the lens impact sound generated when rebounding according to the reduced rebound speed of the lens is less than the first sound decibel threshold, where the first sound decibel threshold is a preset maximum tolerance sound decibel threshold.
Since a user has a tolerance limit that can tolerate a lens impact sound generated when the lens rebounds, when a decibel value of the lens impact sound generated when the lens rebounds exceeds the tolerance limit of the user, the decibel value of the lens impact sound generated when the lens rebounds needs to be reduced by reducing the rebound speed of the lens.
In an example, when it is detected that the decibel value of the lens impact sound is greater than the first sound decibel threshold, the rebound speed of the lens needs to be reduced until the decibel value of the lens impact sound generated when rebounding according to the reduced rebound speed of the lens is less than the first sound decibel threshold. It can be understood that the first sound decibel threshold is a maximum sound decibel threshold that a user can tolerate a lens impact sound generated when the lens rebounds. The first sound decibel threshold may be adjusted according to an actual situation, and in the present disclosure, the first sound decibel threshold is not specifically limited. In an example, the first sound decibel threshold value may be an empirical value. Through this embodiment, can adjust the decibel value of camera lens striking sound automatically to within the biggest tolerance sound decibel threshold value of the camera lens striking sound that the user can tolerate when kick-backing, and then can not bring not good experience for the user.
In the application process, if the decibel value of the lens impact sound meets the maximum sound tolerance decibel threshold of the user, but the decibel value range of the optimal lens impact sound is not reached yet, the decibel value range of the lens impact sound is preset. Therefore, the decibel value of the impact sound of the lens can be further adjusted, so that the adjusted decibel value of the impact sound of the lens conforms to the preset decibel value range of the impact sound of the lens. The present disclosure will explain another process of adjusting the rebound speed of the lens based on the decibel value of the lens impact sound by the following embodiments.
In an exemplary embodiment of the disclosure, if the decibel value of the lens impact sound is greater than the second sound decibel threshold and smaller than the first sound decibel threshold, the rebound speed of the lens is gradually reduced until the reduced rebound speed of the lens is within the preset lens rebound speed range, and the decibel value of the lens impact sound generated when the lens rebound speed is reduced is within the preset lens impact sound decibel value range.
In an embodiment, when it is detected that the decibel value of the lens impact sound is greater than the second sound decibel threshold and smaller than the first sound decibel threshold, the rebound speed of the lens can be reduced step by step until the reduced rebound speed of the lens is within the preset lens rebound speed range, and the decibel value of the lens impact sound generated when the reduced rebound speed of the lens is rebounded is within the preset lens impact sound decibel value range.
It is to be understood that the preset lens rebound speed range may be a rebound speed range which a user considers to be optimal when the lens rebounds, and within the lens rebound speed range, the user does not generate a feeling that the lens response is too sluggish. The preset decibel range of the impact sound of the lens can be the most comfortable decibel range of the impact sound of the lens generated when the user thinks the lens rebounds, and the user cannot generate the feeling that the lens is damaged in the decibel range of the impact sound of the lens. The preset lens rebound speed range and the preset lens impact sound decibel range can be adjusted according to actual conditions, and the preset lens rebound speed range and the preset lens impact sound decibel range are not specifically limited in the disclosure. In one example, the preset lens rebound speed range and the preset lens impact sound decibel range may both be empirical values.
It should be noted that the preset lens impact sound decibel value range includes a preset lens impact sound decibel upper limit value and a preset lens impact sound decibel lower limit value, where the second sound decibel threshold value may be greater than the preset lens impact sound decibel upper limit value.
In the application process, if the rebound speed of the lens is too small and does not reach the preset rebound speed range of the lens, the user can feel that the lens response is too slow. Therefore, the lens rebound velocity can be further adjusted so that the adjusted lens rebound velocity conforms to the preset lens rebound velocity range. The present disclosure will explain still another process of adjusting the rebound speed of the lens based on the decibel value of the lens impact sound point by the following embodiment.
Fig. 5 is a flow chart illustrating adjusting a rebound velocity of a lens based on a decibel value of a lens impact sound according to an exemplary embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 5, adjusting the rebound speed of the lens based on the decibel value of the lens impact sound may include steps S21 and S22, which will be described separately below.
In step S21, a first lens rebound velocity corresponding to the lens at the time of generation of the decibel value of the lens impact sound is determined.
In step S22, if the first lens rebound speed is smaller than the first lens rebound speed threshold, the rebound speed of the lens is increased step by step until the increased lens rebound speed is within the preset lens rebound speed range, and the decibel value of the lens impact sound generated when the lens rebounds according to the increased lens rebound speed is within the preset lens impact sound decibel value range.
In one embodiment, a first lens rebound velocity corresponding to a lens at a decibel value for a lens impact sound generated is determined. It can be understood that, if the rebound speed of the first lens is too low until the user feels that the lens response is slow, it can be stated that the decibel value of the lens impact sound corresponding to the rebound speed of the first lens does not exceed the maximum tolerable sound decibel threshold of the lens impact sound generated when the user can tolerate the lens rebound. In an example, a lens rebound velocity corresponding to a feeling of making a user lens reaction blunted may be defined as a first lens rebound velocity threshold. If the first lens rebound speed is smaller than the first lens rebound speed threshold, the rebound speed of the lens can be increased step by step until the increased rebound speed of the lens is within a preset lens rebound speed range, and the decibel value of the lens impact sound generated during rebound according to the increased rebound speed of the lens is within a preset lens impact sound decibel value range.
According to the foregoing description, in the lens adjustment method provided by the present disclosure, the decibel value of the lens impact sound determined by the sound detection device is obtained, and the rebound speed of the lens is automatically adjusted based on the decibel value of the lens impact sound, so that both the rebound speed of the adjusted lens and the decibel value of the lens impact sound generated when the lens rebounds according to the rebound speed of the adjusted lens meet the requirements of the user. The method can automatically adjust the rebound speed of the lens, reduce the design cost and the material selection cost, and can reduce the workload of debugging personnel without continuously modifying codes by the debugging personnel.
Based on the same concept, a third aspect of the embodiments of the present disclosure also provides a lens adjustment device.
