Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying 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 some, but not all, embodiments of the present disclosure. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure. Embodiments of the present disclosure are described in detail below with reference to the attached drawings.
In the related art, lens switching or lens lifting of a terminal is often driven by a driving motor. The driving motor generally adopts a voice coil motor, and the voice coil motor drives the lens to switch or lift by utilizing the permanent magnetic field of the magnet and the lorentz force generated by the electrified coil. The lens may be fixed by an elastic member such as a spring. When the lens is required to be used (such as focusing, etc.), the driving motor controls the spring to deform and drive the lens to a preset position. When the current lens is not needed, the terminal exits the current lens or switches other lenses different from the current lens, so that the current lens is powered down. When the current lens is powered down, the current lens can generate sound of lens impact in the process that the current position rebounds to the position where the spring does not deform under the action of the tension force of the spring. If the impact sound of the lens generated during rebound is too large, the experience of the user in the use process is affected. Taking the elastic element as an example of a spring, the connection relationship between the lens and the spring can be shown in fig. 1. It will be appreciated that the process of powering down and rebounding the lens in the embodiments of the present disclosure may be understood as a process of powering down the lens and moving from a current use 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-mentioned problems, in the current powering-down process of the lens, the power is usually not immediately cut off, but the lens is slowly moved to the position where the elastic member (such as the spring) has no deformation, and then the power-off process is performed. It should be noted that if the rebound speed is slow during the movement or switching of the lens, a feeling of slow response of the lens will be presented to the user.
According to the lens adjusting device, the rebound speed of the lens can be automatically adjusted based on the decibel value of the lens impact sound through the adjusting control device, so that the rebound speed of the adjusted lens and the decibel value of the lens impact sound generated when rebound according to the rebound speed of the adjusted lens can meet the requirements of users. Therefore, the design cost and the material selecting cost can be reduced, the adjusting control device automatically adjusts the rebound speed of the lens, debugging personnel are not required to continuously modify codes, and the workload of the debugging personnel can be reduced.
A first aspect of an embodiment of the present disclosure provides a lens adjustment apparatus.
Fig. 2 is a lens adjustment apparatus according to an exemplary embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 2, a lens adjusting device 100 includes a sound detecting device 101, a data transmitting device 102, and an adjustment control device 103, and the respective devices and the connection relations between the respective devices will be described below.
The sound detection device 101 may be used to determine a lens impact sound generated when the lens is powered down and rebounds, 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, the current lens will generate lens impact sound in the process of rebounding to the position where the spring does not deform under the action of the tension force of the spring, and the generated lens impact sound is the lens impact sound generated when the lens rebounds. In one example, the sound detection device 101 may collect and determine a decibel value of the lens impact sound. The sound detection device 101 may be a decibel test device, or may be another device capable of determining a sound decibel, 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 striking sound determined by the sound detection device 101 to the adjustment control device 103, and transmit the rebound velocity determined by the adjustment control device 103 to the lens. In one embodiment, the data transfer device 102 may be a universal serial bus (Universal Serial Bus, simply USB transmission line).
In one embodiment, the rebound velocity determined by the adjustment control means 103 may also be transmitted to the terminal 104, wherein the lens is provided on the terminal 104. During application, terminal 104 may control the rebound speed of the lens via a control component of the lens rebound. In an example, the control component that controls the rebound of the lens may be a processing chip of the terminal 104. The processing chip can send instructions to the lens and control the rebound speed of the lens based on the instructions.
It can be understood that, since the distance that the lens moves is a fixed distance in the process of rebounding to the position where the spring is not deformed under the action of the tension force of the spring, the time consumed by the lens in the rebounding process (the time consumed by the lens in the withdrawing or switching process perceived by the user) is affected, 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. Wherein the first universal serial bus is used to connect the sound detection means 101 and the adjustment control means 103. The second universal serial bus is used for connecting the adjustment control device 103 and a control part for controlling the rebound of the lens.
The adjustment control device 103 may be configured to adjust the rebound velocity of the lens based on the decibel value of the impact sound of the lens.
In one embodiment, the adjustment control device 103 may automatically adjust the rebound speed of the lens based on the decibel value of the lens striking sound determined by the sound detection device 101 until the rebound speed of the lens and the decibel value of the lens striking sound generated when rebounding according to the adjusted rebound speed of the lens meet the requirements of the user. I.e. the rebound speed of the lens does not give the user the feeling that the lens is insensitive, and the decibel value of the sound of the lens striking does not give the user the feeling that the lens has been destroyed. In one example, the adjustment control device 103 may be a computer terminal installed with analysis control software.
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 users. Since the adjustment control device 103 automatically adjusts the rebound speed of the lens, the design cost and the material selection cost can be reduced, and the adjustment control device can be realized without continuously modifying codes by a debugging person, so that the workload of the debugging person can be reduced.
The present disclosure will explain another lens adjustment apparatus by the following embodiments.
Fig. 3 is another lens adjustment apparatus according to an exemplary embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 3, the lens adjustment apparatus 200 may further include a housing part 204.
In one example, the housing member 204 may have an accommodation space accommodating a lens, and an opening in which the sound detection device 201 is placed.
In one example, since the lens is disposed on the terminal 205, the terminal 205 may be placed in the accommodating space of the housing part 204, so that the lens impact sound generated by the lens of the terminal 205 during the rebound process is prevented from being interfered by noise outside the housing part 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 formed in the housing member 204. The size of the opening formed in the housing part 204 may be matched with the size of the sound detection device 201, so that noise outside the housing part 204 may not enter the accommodating space of the housing part 204 through the opening, thereby avoiding interference to the sound detection device 201 when determining the decibel value of the lens impact sound. It will be appreciated that the housing member 204 also needs to be provided with a small hole for allowing the data transmission device 202, which connects 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 velocity to the terminal 205 or the lens, thereby controlling the terminal 205 or the lens to adjust the rebound velocity during the rebound process.
In another embodiment, both the sound detection device 201 and the terminal 205 may be placed in the receiving space of the housing part 204, thereby ensuring that the sound detection device 201 is protected from noise outside the housing part 204 during determining the decibel value of the lens-impinging sound.
Further, the housing member 204 is also required to be provided with a small hole 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 is provided to allow the data transmission device 202 (second universal serial bus) connecting the terminal 205 and the adjustment control device 203 to pass through.
According to the embodiment, the decibel value of the lens impact sound can be determined more accurately, and the rebound speed of the lens is automatically adjusted based on the determined 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 rebound according to the rebound speed of the adjusted lens are more accurately in line with the requirements of users.
Based on the same conception, the 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 disclosing 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 embodiment of the present disclosure, where the lens adjusting apparatus may include a sound detecting apparatus. The lens adjustment method may include step S11 and step S12, each of which will be described below.
In step S11, the decibel value of the lens impact sound determined by the sound detection means is acquired.
In step S12, the rebound speed of the lens is adjusted based on the decibel value of the lens striking sound.
In the application process, the current rebound speed of the lens can correspond to the decibel value of the lens impact sound generated when the lens rebounds according to the current rebound speed. Because the rebound speed of the lens and the decibel value of the lens impact sound all influence the visual feeling of the user, and further influence the experience of the user in the use process, the lens adjusting method can automatically adjust the rebound speed of the lens, so that the rebound speed of the lens after adjustment and the decibel value of the lens impact sound generated when rebounding according to the rebound speed of the lens after adjustment meet the requirements of the user.
In one example, the decibel value of the lens striking 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 striking sound. In an embodiment, if the db value of the lens striking sound is greater than the preset threshold, the db value of the lens striking sound generated when the lens is rebounded may be reduced by reducing the rebound speed of the lens, so that the db value of the lens striking sound does not exceed the tolerance limit of the 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 velocity of the lens perceived by the user being too small), the rebound velocity of the lens may be increased, so that the lens is not considered to be too insensitive by the user when rebounding.
According to the lens adjusting method, the decibel value of the lens impact sound determined by the sound detecting 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 rebound according to the rebound speed of the adjusted lens meet the requirements of users. Because the rebound speed of the lens can be automatically adjusted based on the method disclosed by the invention, the design cost and the material selecting cost can be reduced, and the debugging personnel are not required to continuously realize the adjustment by modifying codes, so that the workload of the debugging personnel can be reduced.
The present disclosure will explain a process of adjusting a rebound speed of a lens based on a decibel value of a lens impact sound by the following embodiments.
In an exemplary embodiment of the present disclosure, if the db value of the lens striking sound is greater than the first sound db threshold, the rebound speed of the lens is reduced until the db value of the lens striking sound generated when rebounding according to the reduced rebound speed of the lens is less than the first sound db threshold, where the first sound db threshold is a preset maximum tolerant sound db threshold.
Since the user has a tolerance limit for the lens striking sound generated when the lens is rebounded, when the decibel value of the lens striking sound generated when the lens is rebounded exceeds the tolerance limit of the user, the decibel value of the lens striking sound generated when the lens is rebounded needs to be reduced by reducing the rebounded speed of the lens.
In one example, when the decibel value of the lens striking sound is detected to be greater than the first sound decibel threshold, the rebound velocity of the lens needs to be reduced until the decibel value of the lens striking sound generated when rebounding at the reduced rebound velocity of the lens is less than the first sound decibel threshold. It can be understood that the first sound db threshold is the maximum sound db threshold that can be tolerated by the user for the lens impact sound generated when the lens rebounds. The first sound decibel threshold may be adjusted according to actual situations, and in the present disclosure, the first sound decibel threshold is not specifically limited. In one example, the first sound decibel threshold may be an empirical value. Through the embodiment, the decibel value of the lens impact sound can be automatically adjusted to be within the maximum tolerance sound decibel threshold value of the lens impact sound generated when the lens is rebounded, so that bad experience feeling can not be brought to the user.
In the application process, if the decibel value of the lens impact sound meets the maximum tolerance sound decibel threshold of the user, but the decibel value range of the optimal lens impact sound is not reached, namely the decibel value range of the lens impact sound is preset. Therefore, the decibel value of the lens striking sound can be further adjusted, so that the adjusted decibel value of the lens striking sound accords with the preset range of the decibel value of the lens striking sound. The present disclosure will explain another process of adjusting the rebound speed of a lens based on the decibel value of the impact sound of the lens by the following embodiments.
In an exemplary embodiment of the present disclosure, if the decibel value of the lens striking sound is greater than the second sound decibel threshold and less 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 a preset lens rebound speed range, and the decibel value of the lens striking sound generated when rebounding according to the reduced rebound speed of the lens is within the preset lens striking sound decibel value range.
In one embodiment, when the decibel value of the lens striking sound is detected to be greater than the second sound decibel threshold and less 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 a preset lens rebound speed range, and the decibel value of the lens striking sound generated when rebound is performed according to the reduced rebound speed of the lens is within the preset lens striking sound decibel value range.
It will be appreciated that the preset shot bounce speed range may be a rebound speed range in which the user considers that the shot is optimal when bouncing, and in which the user does not experience too slow a shot response. The preset lens impact sound decibel range may be a most comfortable decibel range of the lens impact sound that the user considers to be generated when the lens rebounds, and in the lens impact sound decibel range, the user does not generate the feeling that the lens has been destroyed. The preset lens rebound speed range and the preset lens impact sound decibel range can be adjusted according to actual conditions, and in the present disclosure, the preset lens rebound speed range and the preset lens impact sound decibel range are not specifically limited. In one example, the preset lens rebound velocity range and the preset lens impact sound decibel range may both be empirical values.
It should be noted that, the range of the preset lens impact sound db value includes an upper limit value of the preset lens impact sound db and a lower limit value of the preset lens impact sound db, where the second sound db threshold may be greater than the upper limit value of the preset lens impact sound db.
In the application process, if the rebound speed of the lens is too small, the user will feel that the response of the lens is too slow when the rebound speed of the lens does not reach the preset rebound speed range of the lens. Therefore, the rebound speed of the lens can be further adjusted so that the adjusted rebound speed of the lens accords with the preset rebound speed range of the lens. The present disclosure will explain a process of adjusting a rebound velocity of a lens based on a shell value of a lens impact sound component by the following embodiments.
Fig. 5 is a flow chart illustrating adjusting the rebound velocity of a lens based on the decibel value of the impact sound of the lens according to an exemplary embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 5, adjusting the rebound velocity of the lens based on the decibel value of the impact sound of the lens may include step S21 and step S22, which will be described below, respectively.
In step S21, a first lens rebound speed corresponding to the lens when the decibel value of the lens striking sound is generated is determined.
In step S22, if the first lens rebound velocity is smaller than the first lens rebound velocity threshold, the rebound velocity of the lens is gradually increased until the increased lens rebound velocity is within a preset lens rebound velocity range, and the decibel value of the lens impact sound generated when rebounding according to the increased lens rebound velocity is within the preset lens impact sound decibel value range.
In one embodiment, a first lens rebound velocity corresponding to a lens when producing a decibel value of a lens impact sound is determined. It can be understood that if the rebound velocity of the first lens is too small until the user experiences a lens with a slow response, it can be stated that the decibel value of the lens striking sound corresponding to the rebound velocity of the first lens does not exceed the maximum tolerant sound decibel threshold of the lens striking sound generated when the user tolerant lens is rebounded. In one example, a lens rebound speed corresponding to a perception of lens unresponsiveness by a user may be defined as a first lens rebound speed threshold. If the rebound speed of the first lens is smaller than the rebound speed threshold value of the first lens, the rebound speed of the lens can be increased step by step until the rebound speed of the increased lens is within a preset rebound speed range of the lens, and the decibel value of the lens impact sound generated when the rebound speed of the increased lens is rebound is within the preset decibel value range of the lens impact sound.
According to the above description, according to the lens adjusting method provided by the present disclosure, the decibel value of the lens striking sound determined by the sound detecting device is obtained, and the rebound speed of the lens is automatically adjusted based on the decibel value of the lens striking sound, so that both the rebound speed of the adjusted lens and the decibel value of the lens striking sound generated when rebounding according to the rebound speed of the adjusted lens satisfy the requirements of the user. Because the rebound speed of the lens can be automatically adjusted based on the method disclosed by the invention, the design cost and the material selecting cost can be reduced, and the debugging personnel are not required to continuously realize the adjustment by modifying codes, so that the workload of the debugging personnel can be reduced.
Based on the same conception, a third aspect of the embodiments of the present disclosure also provides a lens adjustment device.
