[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1, wherein fig. 1 is a flowchart of a camera preview interface anti-shake method according to the present invention. The invention provides an anti-shake method for a camera preview interface, which is applied to a mobile terminal, wherein the mobile terminal can be a mobile phone, a tablet personal computer, a POS (point of sale) machine or a television. The mobile terminal comprises a camera function, and the camera function is used for shooting or recording a shooting target.
In order to realize the function of the camera, a camera is required to be installed in the mobile terminal, the camera comprises a lens group, a focusing motor and an image sensor, an optical image generated by a shooting target through the lens group is projected onto the image sensor, then the optical image is converted into an electric signal, the electric signal is converted into a digital image signal through an A/D conversion module to be stored, then the digital image signal is processed, and the image of the shooting target can be seen through a display.
The anti-shake method for the camera preview interface comprises the following steps:
step S1: and marking the preview state of the mobile terminal, wherein the preview state is a state when the camera focuses on a preview interface.
When the camera function is used, the camera correspondingly enters the preview interface to obtain the image of the shooting target and displays the image on the display, and because the camera does not enter the focusing process, the obtained image of the shooting target may be blurred or incompletely displayed, and the image effect of the shooting target displayed on the display is poor.
And next, the mobile terminal adopts an automatic focusing or semi-automatic focusing mode for focusing, and when the mobile terminal is in a focusing state, the focusing motor drives the lens group to move to a corresponding position according to the distance of the shot target, so that the optical image of the shot target just falls on the image sensor, and the optimal imaging effect is achieved. In the focusing process, the driving motor can adjust the whole position of the lens group and also can adjust the position of a certain lens or a plurality of lenses in the lens group. It will be appreciated that the movement of the focus motor during focusing operation produces vibrations.
When a camera is opened for previewing, a preview interface is displayed on the display, a floating focusing window appears on the preview interface, and the focusing window, namely the focusing area, can be dragged to the floating window at will on the preview interface. The floating window can be in various shapes, the size and the shape of the floating window can be changed by dragging with fingers or other modes, then the floating window area is transmitted into the bottom layer, and the bottom layer algorithm is used for sampling and analyzing the data of the floating window area, so that real-time focusing is realized, and the optimal imaging effect is achieved. The size of the floating focusing window is enlarged or reduced by inputting an adjusting instruction by a user, and the position of the floating focusing window is moved by inputting an adjusting instruction by the user.
Specifically, in this embodiment, the state of the mobile terminal when focusing on the camera preview interface may be marked as the preview state by setting the system attribute or by setting the attribute. It should be noted that when the system attribute or the attribute setting mode is set, the system setting permission or the camera setting permission of the mobile terminal needs to be acquired, and a specific permission acquiring process thereof may be implemented by using a conventional technical means in the art, which is not described in detail herein.
Step S2: when receiving an incoming call request, determining whether the state of the mobile terminal is a preview state, if so, executing step S3; if the preview state is not established, step S4 is executed.
Specifically, the judging process is as follows: and comparing the running state of the camera with the preview state, if the comparison result is consistent, the camera is in the preview state, and if the comparison result is inconsistent, the camera is not in the preview state. The operation state of the camera may be directly obtained from the operation data of the mobile terminal, and in the determination process, the corresponding system permission or camera permission of the mobile terminal may need to be obtained, and the specific process of obtaining the permission may be implemented by using a conventional technical means in the art, which is not described in detail herein.
Preferably, a comparison function may be set, where the comparison function may compare the running state data of the camera and the preview state data one by one, and if a difference between the two data is 0, the preview state of the mobile terminal may be determined.
Step S3: and reducing the voltage of the vibration motor of the mobile terminal.
When receiving an incoming call, the vibration motor of the mobile terminal correspondingly vibrates to send out a ringing tone or generate vibration to remind a user to answer the incoming call. Specifically, the vibration motor comprises a loudspeaker and a vibrator, wherein the loudspeaker and the vibrator are driven by an excitation signal to generate vibration, the loudspeaker is used for giving out an incoming call ringtone and correspondingly generating a slight vibration sensation, and the vibrator is used for giving out strong vibration and correspondingly giving out fine sound.
The vibration intensity of the loudspeaker and the vibrator is positively correlated with the intensity of the excitation signal, namely, the larger the voltage of the excitation signal is, the stronger the vibration is; the larger the voltage of the excitation signal is, the smaller the voltage is, and the smaller the vibration is.
When the mobile terminal is in a preview state, if the vibration frequency generated by the vibration motor is close to the vibration frequency generated by the focusing motor, the vibration motor and the focusing motor can resonate, and the vibrations of the vibration motor and the focusing motor are superposed with each other, so that the vibration quantity of the focusing motor is increased, and the focusing effect is influenced.
The vibration quantity of the vibration motor can be weakened by reducing the voltage of the vibration motor of the mobile terminal, and when the vibration motor resonates with the focusing motor, the vibration quantity generated by the superposition of the vibration motor and the focusing motor is slightly increased compared with the vibration quantity generated by the vibration of the focusing motor, so that the focusing operation is slightly influenced. Preferably, the voltage reduction amount of the vibration motor may set a threshold value, and when the threshold value is reached, the vibration of the vibration motor has a small influence on the vibration of the focusing motor, and is within a range invisible to the naked eye, so that the focusing operation of a user is not influenced.
Of course, in other embodiments, the vibration frequency of the vibration motor may be adjusted to deviate from the vibration frequency of the focusing motor, so as to avoid the resonance of the vibration motor and the focusing motor, but because the vibration frequency of the focusing motor is unstable, the frequency adjustment of the vibration motor also falls into an uncontrollable range, which has a great limitation in practical use, and is not beneficial to popularization and use.
It should be noted that the camera preview interface anti-shake method provided by the present invention does not limit the mobile terminal to perform anti-shake adjustment only when a call is coming, and the camera preview interface anti-shake method of the present invention can be adopted in other processes that need to be applied to a vibrating motor, and all of them belong to the protection scope of the present invention.
Step S4: maintaining a voltage of the vibration motor at a rated value.
If the mobile terminal is not in the preview state, the voltage of the vibration motor is kept as a rated value, so that the vibration state of the vibration motor is in the rated state, and the ringing can be normally performed and the vibration sense can be generated. At this time, since the focus motor does not operate, the focus motor and the focus motor do not resonate with each other.
Step S5: and if the incoming call is answered or refused, restoring the voltage of the vibrating motor to be a rated value.
It can be understood that, no matter whether the incoming call is answered, the incoming call is rejected or the incoming call is muted, the incoming call is stopped, that is, the vibration motor stops working, at this time, the working of the focusing motor is not influenced, the voltage of the vibration motor can be recovered to a rated value for the next normal vibration requirement, and the steps S1-S4 are repeated when the incoming call is next time, so that the vibration motor of the mobile terminal is ensured not to influence the vibration of the focusing motor.
Referring to fig. 2, fig. 2 is a schematic connection diagram of an anti-shake apparatus for a preview interface of a camera according to the present invention. The invention also provides an anti-shake device 100 for a preview interface of a camera, wherein the anti-shake device 100 comprises a marking module 10, a judging module 20, a processing module 30 and a recovering module 40. The marking module 10, the judging module 20 and the recovering module 40 are all electrically connected to the processing module 30, and the processing module 30 processes, analyzes and responds to the operation data fed back to the processing module 30, and controls corresponding hardware structures in the mobile terminal to react, thereby completing a final adjusting process.
The marking module 10 is configured to mark a preview state of the mobile terminal, where the preview state is a state when the camera focuses on a preview interface.
When the camera function is used, the camera correspondingly enters the preview interface to obtain the image of the shooting target and displays the image on the display, and because the camera does not enter the focusing process, the obtained image of the shooting target may be blurred or incompletely displayed, and the image effect of the shooting target displayed on the display is poor.
And next, the mobile terminal adopts an automatic focusing or semi-automatic focusing mode for focusing, and when the mobile terminal is in a focusing state, the focusing motor drives the lens group to move to a corresponding position according to the distance of the shot target, so that the optical image of the shot target just falls on the image sensor, and the optimal imaging effect is achieved. In the focusing process, the driving motor can adjust the whole position of the lens group and also can adjust the position of a certain lens or a plurality of lenses in the lens group. It will be appreciated that the movement of the focus motor during focusing operation produces vibrations.
When a camera is opened for previewing, a preview interface is displayed on the display, a floating focusing window appears on the preview interface, and the focusing window, namely the focusing area, can be dragged to the floating window at will on the preview interface. The floating window can be in various shapes, the size and the shape of the floating window can be changed by dragging with fingers or other modes, then the floating window area is transmitted into the bottom layer, and the bottom layer algorithm is used for sampling and analyzing the data of the floating window area, so that real-time focusing is realized, and the optimal imaging effect is achieved. The size of the floating focusing window is enlarged or reduced by inputting an adjusting instruction by a user, and the position of the floating focusing window is moved by inputting an adjusting instruction by the user.
Specifically, in this embodiment, the marking module 10 may mark the state of the mobile terminal when focusing is performed on the camera preview interface as the preview state by setting a system attribute or by setting an attribute. It should be noted that, when setting the system attribute or setting the attribute formula, the marking module 10 needs to acquire the corresponding system setting permission or camera setting permission of the mobile terminal, and a specific process of acquiring the permission adopts a conventional technical means in the art, which is not described in detail herein.
The determining module 20 is configured to determine whether the state of the mobile terminal is a preview state when receiving an incoming call request.
Specifically, the judging process of the judging module 20 is as follows: and comparing the running state of the camera with the preview state, if the comparison result is consistent, the mobile terminal is in the preview state, and if the comparison result is inconsistent, the mobile terminal is not in the preview state. The operation state of the camera may be directly obtained from the operation data of the mobile terminal, and in the determination process, the corresponding system permission or camera permission of the mobile terminal may need to be obtained, and the specific process of obtaining the permission may be implemented by using a conventional technical means in the art, which is not described in detail herein.
Preferably, the determining module 20 may set a comparison function, where the comparison function may compare the running state data of the camera and the preview state data one by one, and if a difference between the running state data and the preview state data is 0, the preview state of the mobile terminal may be determined.
The processing module 30 is configured to reduce the voltage of the mobile terminal vibration motor or maintain the voltage of the vibration motor at a rated value, specifically, if the mobile terminal vibration motor is in a preview state, the processing module 30 reduces the voltage of the mobile terminal vibration motor; if not, the processing module 30 maintains the voltage of the vibration motor at a nominal value.
When receiving an incoming call, the vibration motor of the mobile terminal correspondingly vibrates to send out a ringing tone or generate vibration to remind a user to answer the incoming call. Specifically, the vibration motor comprises a loudspeaker and a vibrator, wherein the loudspeaker and the vibrator are driven by an excitation signal to generate vibration, the loudspeaker is used for giving out an incoming call ringtone and correspondingly generating a slight vibration sensation, and the vibrator is used for giving out strong vibration and correspondingly giving out fine sound.
The vibration intensity of the loudspeaker and the vibrator is positively correlated with the intensity of the excitation signal, namely, the larger the voltage of the excitation signal is, the stronger the vibration is; the larger the voltage of the excitation signal is, the smaller the voltage is, and the smaller the vibration is.
When the mobile terminal is in a preview state, if the vibration frequency generated by the vibration motor is close to the vibration frequency generated by the focusing motor, the vibration motor and the focusing motor can resonate, and the vibrations of the vibration motor and the focusing motor are superposed with each other, so that the vibration quantity of the focusing motor is increased, and the focusing effect is influenced.
Therefore, the invention can weaken the vibration quantity of the vibration motor by reducing the voltage of the vibration motor of the mobile terminal, when the vibration motor and the focusing motor resonate, the vibration quantity generated by the superposition of the vibration motor and the focusing motor is increased less than the vibration quantity generated by the vibration of the focusing motor, and the influence on the focusing operation is less. Preferably, the voltage reduction amount of the vibration motor may set a threshold value, and when the threshold value is reached, the vibration of the vibration motor has a small influence on the vibration of the focusing motor, and is within a range invisible to the naked eye, so that the focusing operation of a user is not influenced.
The marking module 10 and the judging module 20 are both electrically connected to the processing module 30, the marking information of the marking module 10 and the judging result of the judging module 20 are both fed back to the processing module 30, and the processing module 30 is connected to an exciter of the vibration motor and is used for controlling the working state of the exciter and further adjusting the voltage of an exciting signal sent by the exciter.
The recovery module 40 is configured to recover the voltage of the vibration motor to a rated value when the incoming call is answered or rejected.
It can be understood that, no matter whether the incoming call is answered, rejected or muted, the incoming call ringtone will be stopped, that is, the vibration motor stops working, and at this time, the working of the focusing motor will not be affected, and the voltage of the vibration motor can be restored to a rated value for the next normal vibration requirement, and the steps S1-S4 are repeated for the next incoming call, so that the vibration motor of the mobile terminal will not affect the vibration of the focusing motor.
The recovery module 40 is also electrically connected to the processing module 30, and when the voltage of the vibration motor needs to be recovered, the recovery module 40 sends a signal to the processing module 30, and the processing module 30 controls the working state of the exciter, so as to adjust the voltage of the excitation signal sent by the exciter to a rated value.
