The following describes the anti-shake control method provided by the embodiment of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present application provides an anti-shake control method, which is optionally applicable to electronic devices including various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of Mobile Stations (MSs), Terminal devices (Terminal devices), and the like.
The method comprises the following steps:
Optionally, the electronic device may start a shooting operation when receiving the first input; the image frame may be a picture or a video frame, and the shooting operation may be shooting a photo video or the like, for example, a user touches a camera key of the electronic device to shoot; or starting shooting operation through an application program; or the application program automatically starts shooting operation, for example, the electronic device is a vehicle event data recorder, and pictures, videos and the like are shot in real time in the driving process. Acquiring current vibration parameters in the process of shooting images by a camera; the vibration parameters are used for evaluating whether the current motion state of the electronic equipment is violent, for example, if the user holds the electronic equipment for shooting, the motion state is non-violent motion; and if the speed of a vehicle is faster during the driving process, the user may move violently.
The vibration parameter includes at least one of a frequency parameter and an amplitude parameter. Specifically, the frequency parameter is the current frequency of the electronic device, and the frequency is the number of times of completing the periodic change in unit time and is a quantity describing the frequency degree of the periodic movement; in the vibration state, when the vibration object completes reciprocating motion once, the frequency is increased by one, namely the frequency of vibration circulation of the electronic equipment in each second, the current motion state of the electronic equipment is judged to be high-frequency vibration or low-frequency vibration through the vibration frequency, and then the motion intensity of the electronic equipment is judged through the high-frequency vibration and the low-frequency vibration.
The amplitude parameter is the current amplitude of the electronic device, and the amplitude is the maximum value that the physical quantity of vibration can reach, and is the physical quantity representing the range and the intensity of vibration. The intensity of the movement of the electronic equipment can be judged according to the amplitude of the electronic equipment.
And 102, determining a target anti-shake type according to the vibration parameters.
Judging a target anti-shake type according to the vibration parameters of the electronic equipment, wherein the target anti-shake type is an anti-shake type matched with the current motion state of the electronic equipment; optionally, the anti-shake type includes electronic anti-shake, optical anti-shake, pan-tilt anti-shake, and the like; optical Image Stabilization (Optical Image Stabilization) is to avoid or reduce the instrument shake phenomenon occurring in the process of capturing an Optical signal by setting Optical components, such as a lens, in the shooting process, so as to improve the imaging quality. The optical anti-shake principle is that a micro movement is detected by a gyroscope in a lens, then a signal is transmitted to a microprocessor, the processor immediately calculates a displacement amount to be compensated, and then compensation is performed according to the shake direction and the displacement amount of the lens through a compensation lens group, so that image blurring caused by vibration of a camera is effectively overcome. The optical anti-shake system has high requirements on the design and manufacture of the lens and relatively high cost. The anti-shake of the tripod head is realized by simultaneously compensating the lens group and the photosensitive device, so that the image blur caused by the vibration of the camera is effectively overcome.
Electronic Image Stabilization (EIS) mainly uses Charge-coupled Device (CCD) offset to realize anti-shake, the CCD is first mounted on a support capable of moving up, down, left and right, and when shake is detected, parameters such as shake direction, speed and movement are processed to calculate the CCD movement enough to counteract shake. The electronic anti-shake is actually a technology for compensating shake by reducing image quality, compared with the optical anti-shake technology, the electronic anti-shake effectively avoids the spherical aberration problem caused by a compensation mode, and simultaneously solves the volume limitation which puzzles the single lens reflex lens, but the effect is inferior to the optical anti-shake.
The effect of optics anti-shake and cloud platform anti-shake is better, but under some motion states, uses optics anti-shake or cloud platform anti-shake to damage corresponding anti-shake subassembly easily, consequently, in this application embodiment, according to vibration parameter, matches the target anti-shake type that corresponds with current motion state, carries out the shooting operation according to target anti-shake type.
And 103, executing shooting operation according to the target anti-shake type.
And executing shooting operation according to the target anti-shake type to enable the anti-shake type to be matched with the current motion state, and if the current motion state is not matched with the currently executed anti-shake type, switching the anti-shake type to avoid causing and damaging anti-shake components of the electronic equipment.

The optical anti-shake module is prevented from being damaged by an optical anti-shake mode in a violent motion state, and the service life of the optical anti-shake module is prolonged. The embodiment of the application solves the problem that in the prior art, under special use conditions, for example, under a motion state, an optical anti-shake function is used, and an optical anti-shake component of the electronic equipment is easily damaged.
Referring to fig. 2, another embodiment of the present application provides an anti-shake control method, including:
Optionally, the electronic device may start a shooting operation when receiving the first input; the image frame may be a picture or a video frame, and the shooting operation may be shooting a photo video or the like, for example, a user touches a camera key of the electronic device to shoot; or starting shooting operation through an application program; or the application program automatically starts shooting operation, for example, the electronic device is a vehicle event data recorder, and pictures, videos and the like are shot in real time in the driving process. Acquiring current vibration parameters in the process of shooting images by a camera; the vibration parameters are used for evaluating whether the current motion state of the electronic equipment is violent, for example, if the user holds the electronic equipment for shooting, the motion state is non-violent motion; and if the speed of a vehicle is faster during the driving process, the user may move violently.
The vibration parameter includes at least one of a frequency parameter and an amplitude parameter. Specifically, the frequency parameter is the current frequency of the electronic device, and the frequency is the number of times of completing the periodic change in unit time and is a quantity describing the frequency degree of the periodic movement; in the vibration state, when the vibration object completes reciprocating motion once, the frequency is increased by one, namely the frequency of vibration circulation of the electronic equipment in each second, the current motion state of the electronic equipment is judged to be high-frequency vibration or low-frequency vibration through the vibration frequency, and then the motion intensity of the electronic equipment is judged through the high-frequency vibration and the low-frequency vibration.
The amplitude parameter is the current amplitude of the electronic device, and the amplitude is the maximum value that the physical quantity of vibration can reach, and is the physical quantity representing the range and the intensity of vibration. The intensity of the movement of the electronic equipment can be judged according to the amplitude of the electronic equipment.
The correspondence is a correspondence between the vibration parameter and the vibration mode, for example, the vibration mode may include a high-frequency vibration mode and a low-frequency vibration mode, and may further include a handheld vibration mode and a vehicle-mounted vibration mode.
The correspondence includes a parameter range of the vibration parameter matching each vibration mode. For example, when the vibration parameter includes one of an amplitude parameter and a frequency parameter, the correspondence relationship includes an amplitude parameter or a frequency parameter data range that matches each vibration mode. When the vibration parameters include the amplitude parameter or the frequency parameter, the corresponding relationship includes the amplitude parameter and the data range of the frequency parameter matched with each vibration mode.
And step 203, determining a target anti-shake type corresponding to the vibration mode.
After the vibration mode is determined, executing a target anti-shake type corresponding to the vibration mode; for example, if the vibration mode is high-frequency vibration, the target anti-shake type is electronic anti-shake.
And 204, determining a target anti-shake type according to the vibration parameters.
And judging a target anti-shake type according to the vibration parameters of the electronic equipment, wherein the target anti-shake type is an anti-shake type matched with the current motion state of the electronic equipment.
In an optional embodiment, in a case where the vibration parameter includes the frequency parameter and the amplitude parameter, the correspondence relationship includes a first data range and a second data range corresponding to each of the vibration modes;
the first data range comprises a data range of the frequency parameter;
the second data range includes a data range of the amplitude parameter.
That is, when the vibration parameter includes both the frequency parameter and the amplitude parameter, the correspondence relationship includes a first data range and a second data range corresponding to each vibration mode. For a vibration mode, when the frequency parameter satisfies a first data range corresponding to the mode and the amplitude parameter satisfies a second data range corresponding to the mode, the electronic device currently belongs to the vibration mode.
In an optional embodiment, the vibration parameter comprises the frequency parameter and the amplitude parameter, and the vibration mode comprises a first vibration mode and a second vibration mode;
the corresponding relation comprises a first data range and a second data range corresponding to each vibration mode; the first data range comprises a data range of the frequency parameter; the second data range comprises a data range of the amplitude parameter;
the first data range of the first vibration mode comprises a data range larger than a first preset frequency, and the second data range of the first vibration mode comprises a data range smaller than a first preset amplitude; that is, the first vibration mode has a higher vibration frequency and a smaller vibration amplitude.
The first data range of the second vibration mode includes a data range smaller than a second preset frequency, and the second data range of the first vibration mode includes a data range larger than a second preset amplitude, that is, the vibration frequency of the first vibration mode is lower, and the vibration amplitude is larger.
Taking the first vibration mode as the vehicle-mounted vibration mode and the second vibration mode as the handheld vibration mode as an example, as a first example, with reference to fig. 3, fig. 3 shows a schematic diagram of frequency parameter variation with time, where the horizontal axis t is time and the unit is second; the vertical axis G represents the vibration acceleration, wherein the unit of the vertical axis is the gravity acceleration G; s1 shows a first vibration mode, and S2 shows a second vibration mode, so that in the first vibration mode, the vibration acceleration is changed more frequently, and in the preset period, the positive and negative change times of the acceleration are equal to one half of the frequency, and in the case of simple harmonic vibration, for example, the acceleration changes once in positive and negative values, which indicates that the vibrating object experiences a primary wave peak or a wave trough, i.e., one-half cycle vibration is completed, so that the acceleration changes 2 times between the positive and negative values, which is equal to the frequency times plus 1. Referring to fig. 3, the number of times of change of the positive and negative values of the first vibration mode in the same time period is significantly greater than that of the second vibration mode, and the first data range includes a data range greater than the first preset frequency.
Through the two numerical values, when the change frequency of the positive value and the negative value of the numerical value of the acceleration sensor exceeds 20Hz and the acceleration value exceeds 1g, the situation that high-frequency vibration exists in the use scene can be judged.
With reference to FIG. 4, the vertical axis of FIG. 4 is amplitude A in millimeters; the horizontal axis t is time in seconds; s1 shows the first vibration mode, and S2 shows the second vibration mode, whereby it can be seen that the amplitude is smaller in the first vibration mode than in the second vibration mode.
For example, when the electronic device is placed on a vehicle, the vibration frequency of the acceleration sensor in any one direction of the X axis, the Y axis, and the Z axis may be 20Hz or more, and the acceleration generated during vibration may be 2g or more (g is gravitational acceleration). And the vibration frequency of the handheld state hardly exceeds 5Hz, and the acceleration value hardly exceeds 1 g. The vibration generated by the machine belongs to high-frequency low-amplitude vibration, the vibration generated by the hand-held machine is low-frequency high-amplitude vibration, the vibration generated by the machine is relatively regular, the vibration generated by the hand-held machine is relatively irregular, and the vibration can be obviously distinguished through the calculated waveform.
Under the low amplitude vibration of high frequency, close optics anti-shake subassembly, switch into electron anti-shake, cut through the picture of electron anti-shake, also can realize shooing, video recording anti-shake effect, protected optics anti-shake's mechanical structure simultaneously.
In an alternative embodiment, the electronic device includes an acceleration sensor;
the acquiring of the vibration parameters of the electronic device comprises:
and acquiring the vibration parameters of the electronic equipment through the acceleration sensor.
The vibration acceleration is measured through the acceleration sensor, and the vibration amplitude and the vibration frequency can be calculated through the vibration acceleration value and the vibration time; the amplitude is displacement, and the displacement is equal to the square value of the acceleration multiplied by the time; the vibration frequency is equal to one half of the change frequency of the positive and negative values of the acceleration.
In an alternative embodiment, the method comprises:
when the starting of the camera is detected, starting a first anti-shake module of the electronic equipment; optionally, the anti-shake module may be an optical anti-shake module, and when a camera of the electronic device is turned on, the optical anti-shake module is started by default;
and if the vibration mode of the electronic equipment is a third vibration mode, closing the first anti-shake module.
The third vibration mode may be a high-frequency low-amplitude vibration, such as the aforementioned first vibration mode; the optics anti-shake effect is better, but under some motion states, for example the low amplitude of high frequency, uses optics anti-shake to damage optics anti-shake subassembly easily, consequently, under the low amplitude of vibration of high frequency, closes optics anti-shake module, switches into the electronics anti-shake, cuts through the picture of electronics anti-shake, also can realize shooing, video recording anti-shake effect, has protected the mechanical structure of optics anti-shake simultaneously.
In an optional embodiment, after the first anti-shake module is turned off, the method includes:
if the vibration mode of the electronic equipment is not the third vibration mode, the first anti-shake module is started, namely, the vibration mode is not high-frequency low-amplitude vibration, and the first anti-shake module is still started at the moment in order to guarantee the shooting effect. At this moment, after finishing the high-frequency low-amplitude vibration, the corresponding first anti-shake module is started again in time, so that the shooting effect can be ensured.
In the embodiment of the application, in the process of shooting the image by the camera, the vibration parameters of the electronic equipment are obtained; determining a target anti-shake type according to the vibration parameters; according to the target anti-shake type, shooting operation is executed, so that the electronic equipment adopts the anti-shake type matched with the current motion state to execute the shooting operation, the optical anti-shake mode is prevented from being used in a violent motion state, the optical anti-shake component is prevented from being damaged, and the service life of the optical anti-shake module is prolonged.
