Detailed Description
Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the like or similar elements throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The embodiment of the application provides a screen display anti-shaking method for a mobile terminal, aiming at the problems that in the related art, as the handheld mobile terminal can cause large shaking, the text or image details on a screen shake at the same speed and amplitude, so that the eyes of people are in the process of continuously focusing adjustment, visual fatigue is easily caused, and the user experience is influenced.
According to the anti-shaking method for screen display of the mobile terminal, when the situation that the mobile terminal is in a shaking state is monitored in the screen display process of the mobile terminal, the current three-dimensional shaking state data of the mobile terminal is obtained, the liquid level fluctuation data corresponding to the current three-dimensional shaking state data are determined based on the liquid container model corresponding to the mobile terminal, then the compensation data of the current display content of the screen are determined according to the liquid level fluctuation data, and then the shaking display compensation is carried out on the current display content of the screen according to the compensation data.

The following describes a mobile terminal screen display anti-shake method, apparatus, mobile terminal, storage medium, and computer program provided by the present application in detail with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating an anti-shake method for displaying on a screen of a mobile terminal according to an embodiment of the present disclosure.
As shown in fig. 1, the anti-shaking method for screen display of a mobile terminal includes the following steps:
It should be noted that, when people use the mobile terminal while walking or in a bumpy vehicle, due to the handheld shaking of the mobile terminal, the display content of the screen of the mobile terminal may shake at the same speed and amplitude with the shaking of the mobile terminal, so that the eyes of people are in the process of continuously focusing adjustment, which is easy to cause visual fatigue and affects the user experience. Therefore, the anti-shaking method for the screen display of the mobile terminal in the embodiment of the application can perform shaking compensation on the current display content of the screen of the mobile terminal according to the current three-dimensional shaking state data of the mobile terminal, so as to reduce the position change degree of the screen display content in the shaking process of the mobile terminal, and further achieve the effect of reducing the visual fatigue of human eyes.
It should be noted that the anti-shake method for screen display of a mobile terminal according to the embodiment of the present application may be executed by the anti-shake apparatus for screen display of a mobile terminal according to the embodiment of the present application. The anti-shaking device for screen display of the mobile terminal can be configured in any mobile terminal, so that shaking of display contents of a screen of the mobile terminal is compensated when the mobile terminal shakes. The mobile terminal of the present application may include a hardware device having a display screen, such as a mobile phone, a tablet computer, a personal digital assistant, and a wearable device, but is not limited thereto.
The current three-dimensional jitter state data of the mobile terminal refers to the current motion data of the mobile terminal in a three-dimensional space, wherein three pairwise vertical axial directions of the three-dimensional space can be represented by an X axis, a Y axis and a Z axis respectively. The current three-dimensional jitter state data of the mobile terminal can be represented by the motion data of the mobile terminal on the X axis, the Y axis and the Z axis respectively.
It should be noted that the current three-dimensional shaking state data of the mobile terminal may be acquired by a motion sensor in the mobile terminal, that is, an output value of the motion sensor in the mobile terminal to be acquired is determined as the current three-dimensional shaking state data of the mobile terminal. The motion sensor may include, but is not limited to, a gyroscope, an accelerometer, a gravity sensor, a vibration sensor, or other devices that can output three-dimensional state data of the mobile terminal.
As a possible implementation manner, since the acceleration of the mobile terminal may reflect the shaking degree of the mobile terminal, the current three-dimensional shaking state data of the mobile terminal may be the current acceleration values of the mobile terminal in three directions X, Y, Z, respectively, that is, the current three-dimensional shaking state data of the mobile terminal may be determined according to the output values of a gyroscope or an accelerometer in the mobile terminal.
In the embodiment of the application, in the process of displaying the screen of the mobile terminal, that is, when it is detected that the screen of the mobile terminal is in the working state, the output values (such as the output value of a gyroscope) of one or more motion sensors in the mobile terminal are obtained in real time, and then whether the mobile terminal is in the shaking state is determined according to the output values of the one or more motion sensors, and if the mobile terminal is determined to be in the shaking state, the obtained output values of the motion sensors can be determined as the current three-dimensional shaking state data of the mobile terminal.
Specifically, the type of the motion sensor may be preset, for example, the motion sensor may be preset as a gyroscope, that is, an output value of the gyroscope in the mobile terminal may be obtained in real time, and according to the output value of the gyroscope, current acceleration values of the mobile terminal in X, Y, Z three directions respectively are determined, and then when a mean value of the current acceleration values of the mobile terminal in the three directions is greater than a preset threshold, it is determined that the mobile terminal is currently in a shaking state, and the current acceleration values of the mobile terminal in X, Y, Z three directions respectively are determined as current three-dimensional shaking state data of the mobile terminal.
It should be noted that the above examples are only illustrative and should not be construed as limiting the present application. In practical use, a motion sensor used for detecting the shaking state of the mobile terminal can be preset according to actual needs, and conditions which need to be met when the mobile terminal belongs to the shaking state are determined.
Furthermore, when the mobile terminal is detected to be in a shaking state, whether the current shaking is actively triggered by the user can be further determined, and the condition that compensation is not needed is eliminated, so that the operating pressure of the mobile terminal is reduced. That is, in a possible implementation form of the embodiment of the present application, before the obtaining the current three-dimensional shaking state data of the mobile terminal, the method further includes:
and determining that the current jitter state duration of the mobile terminal is greater than a threshold value.
In the embodiment of the application, the display compensation can be performed on the display content of the screen of the mobile terminal only when the screen of the mobile terminal is determined to be in the display state and the mobile terminal is in the continuous shaking state which is not expected by a user; and when the short-time jitter which is actively triggered by the user occurs, the jitter compensation is not carried out on the display content of the screen of the mobile terminal, so that the operation burden of the mobile terminal is prevented from being increased.
As a possible implementation, jitter that is actively triggered by the user is typically of a short duration, such as a need to trigger functions of certain applications in the mobile terminal by shaking the mobile terminal, and jitter that is undesirable to the user is typically of a longer duration, such as the user being in a walking state or riding in a bumpy vehicle. Therefore, whether the current three-dimensional jitter state data of the mobile terminal needs to be continuously acquired or not can be determined according to the current jitter state duration of the mobile terminal so as to perform jitter compensation. Specifically, if the duration of the current shaking state of the mobile terminal is less than the threshold, it may be determined that the shaking occurring at the current time of the mobile terminal may be actively triggered by the user, or the influence on the reading of the user is small, that is, the current three-dimensional shaking state data of the mobile terminal may not be continuously obtained, so as to reduce the operation burden of the mobile terminal; if the duration time of the current jitter state of the mobile terminal is greater than the threshold value, the jitter currently sent by the mobile terminal can be determined to be the continuous jitter which is not expected by the user, so that the current three-dimensional jitter state data of the mobile terminal can be further acquired, and data preparation is carried out on the subsequent display content compensation operation.
It should be noted that, in actual use, the threshold that needs to be met by the duration of the jitter state of the mobile terminal may be preset according to actual needs or experience, and this is not limited in this embodiment of the present application. For example, it may be 3 seconds.
And 102, determining liquid level fluctuation data corresponding to the current three-dimensional shaking state data based on a liquid container model corresponding to the mobile terminal.
The liquid container model corresponding to the mobile terminal is a model established by regarding the mobile terminal as a container for containing liquid, regarding a screen of the mobile terminal as the liquid surface, and regarding display contents in the screen of the mobile terminal as a plane floating object of the liquid surface. The liquid container model corresponding to the mobile terminal may include a conversion relationship between three-dimensional shaking state data and page fluctuation data of the mobile terminal.
It will be appreciated that by placing an object directly on the shake plane and a container holding liquid on the shake plane on the same shake plane, the shake of the object directly on the shake plane is greater than the fluctuation of the liquid surface. Therefore, the shaking display compensation is carried out on the display content of the screen of the mobile terminal by establishing the liquid container model corresponding to the mobile terminal, so that the display content of the screen has a stereoscopic impression, and the compensation effect is more natural.
As a possible implementation manner, a liquid container model corresponding to the mobile terminal may be established in advance through experiments. Alternatively, the experiment may be performed on a dithering plane, and the dithering plane may be further dithered up and down, dithered left and right, dithered rotationally, and the like in a three-dimensional space in various postures and degrees. And a container for containing liquid is placed on the shaking plane, and liquid level fluctuation data corresponding to the liquid surface under each three-dimensional shaking state data is determined by adjusting the three-dimensional shaking state data of the shaking plane, so that the conversion relation between the three-dimensional shaking state data and the liquid level fluctuation data, namely a liquid container model corresponding to the mobile terminal is determined.
In the embodiment of the application, after the current three-dimensional shaking state data of the mobile terminal is determined, the liquid level fluctuation data corresponding to the current three-dimensional shaking state data of the mobile terminal can be determined according to the conversion relationship between the three-dimensional shaking state data and the liquid level fluctuation data included in the liquid container model corresponding to the mobile terminal.
And 103, determining compensation data of the current display content of the screen according to the liquid level fluctuation data.
In the embodiment of the application, after the liquid level fluctuation data corresponding to the current three-dimensional shaking state data of the mobile terminal is determined, the compensation data of the current display content of the screen of the mobile terminal can be determined according to the determined liquid level fluctuation data.
Optionally, the corresponding relationship between the liquid level fluctuation data and the supplemental data may be preset, so that the compensation data of the current display content of the screen may be determined according to the determined page fluctuation data and the corresponding relationship between the liquid level fluctuation data and the supplemental data.
Optionally, the compensation data of the current display content of the screen may be generated in real time according to the determined page fluctuation data. Specifically, the value of the compensation data of the current display content of the screen may be the same as the value of the determined page fluctuation data, and the directions are opposite, so that when the mobile terminal is in a shaking state, the relative position between the display content of the screen and human eyes is unchanged, or the degree of displacement change is reduced.
For example, if the liquid level fluctuation data and the compensation data of the display content both include X, Y, Z values in three directions, and the determined liquid level fluctuation data is (a, b, c), the compensation data of the current display content on the screen is (-a, -b, -c).
And 104, performing jitter display compensation on the current display content of the screen according to the compensation data.
In the embodiment of the application, after the compensation data of the current display content of the screen is determined, the pixel value of each pixel point in the screen can be adjusted according to the compensation data, so that the display position of the display content in the screen is continuously changed along with the shaking of the mobile terminal, the position relation between the display content and human eyes is relatively fixed, or the change degree of displacement is reduced, the human eyes do not need to frequently adjust focuses, and the visual fatigue of the human eyes is reduced.
According to the anti-shaking method for screen display of the mobile terminal, when the situation that the mobile terminal is in a shaking state is monitored in the screen display process of the mobile terminal, the current three-dimensional shaking state data of the mobile terminal is obtained, the liquid level fluctuation data corresponding to the current three-dimensional shaking state data are determined based on the liquid container model corresponding to the mobile terminal, then the compensation data of the current display content of the screen are determined according to the liquid level fluctuation data, and then the shaking display compensation is carried out on the current display content of the screen according to the compensation data. Therefore, the current display content of the screen is subjected to shaking display compensation according to the current three-dimensional shaking state data of the mobile terminal and the liquid container model established in advance, so that the position change degree of the display content of the screen is reduced, the visual fatigue of human eyes is relieved, and the user experience is improved.
In a possible implementation form of the embodiment of the application, when the display content types of the screen of the mobile terminal are different, different compensation modes can be adopted for compensation according to the characteristics of the display contents of the different types, so as to further improve the compensation effect.
The method for preventing shaking of screen display of a mobile terminal according to an embodiment of the present application is further described with reference to fig. 2.
Fig. 2 is a flowchart illustrating another anti-shake method for displaying on a screen of a mobile terminal according to an embodiment of the present application.
As shown in fig. 2, the anti-shaking method for screen display of a mobile terminal includes the following steps:
The detailed implementation process and principle of the steps 201-202 can refer to the detailed description of the above embodiments, and are not described herein again.
The type of the content currently displayed on the screen may include a text type, a picture type, a video type, a mixed type, and the like. It should be noted that, when the currently displayed content of the screen includes multiple types, the type of the currently displayed content of the screen may be determined to be a mixed type.
In the embodiment of the application, the type of the current display content of the screen can be directly obtained from the processor of the mobile terminal, and then when the jitter states of the mobile terminal are the same, different jitter compensations can be performed according to the characteristics of different types of display content, so as to improve the jitter compensation effect.
And step 204, determining the current compensation mode according to the type of the current display content.
The compensation mode may include a corresponding relationship between the liquid level fluctuation data and the compensation data in the compensation mode.
In the embodiment of the present application, a corresponding relationship between the display content type and the compensation mode may be preset, so that after the determined type of the current display content is determined, the compensation mode corresponding to the type of the current display content may be determined as the current compensation mode according to the type of the current display content and the corresponding relationship between the display content type and the compensation mode.
For example, for the text type display content, the frame switching speed is slow, while for the video type content, the frame switching speed is fast, so that under the same dithering state, the compensation for the text type display content can be increased properly, and the compensation for the video type display content can be decreased properly. For example, the compensation mode of the display content of the character type can be the adjustment font, and the effect that human eyes do not need to adjust the focus point is achieved by changing the characters into three-dimensional characters (the projection of the compensated three-dimensional characters on the original screen is the same as the original display position).
It should be noted that, the correspondence between the type of the display content and the compensation mode may also be modified according to the setting operation of the user, so that the final compensation effect better meets the use requirement of the user.
As a possible implementation, the larger the mass of an object, the greater its inertia, according to newton's second law. Therefore, in the embodiment of the present application, an inertial system may be simulated, and different types of display contents are regarded as objects with different qualities, that is, different reference values are assigned to the different types of display contents, and a correspondence between a reference value range and a compensation mode is preset, so that a current compensation mode is determined according to a reference value range to which the reference value corresponding to the current display content belongs.
Further, the screen of the mobile terminal may include multiple types of display contents, and the current compensation mode may be determined according to reference values respectively corresponding to the multiple types of display contents. In a possible implementation form of the embodiment of the present application, the current display content of the screen includes at least two types; accordingly, the step 204 may include:
determining a target reference quantity corresponding to the current display content according to a mapping relation between a preset type and a reference quantity value;
and determining the current compensation mode according to the reference range to which the target reference quantity belongs.
The reference value may refer to a quality assigned to each type of display content.
As a possible implementation manner, each type of display content may correspond to a reference quantity value and a weight value, when the current screen display content includes multiple types, the reference quantity value corresponding to each type of display content included in the current screen display content may be determined according to a mapping relationship between a preset type and the reference quantity value, and then the target reference quantity corresponding to the current screen display content may be determined according to the reference quantity value and the weight value respectively corresponding to the multiple types of display content included.
Specifically, the weighted sum of the reference quantities respectively corresponding to the multiple types of display contents included in the current display content may be determined as the target reference quantity corresponding to the current display content, and may be represented by the following formula:
wherein m is a target reference quantity corresponding to the current display content, w i Weight value m corresponding to the display content of the ith type i The reference value corresponding to the ith type of display content is obtained, i is the serial number of the display content included in the current display content, and n is the type number of the display content included in the current display content.
As a possible implementation manner, a corresponding relationship between the reference magnitude range and the compensation mode may be preset, so that the compensation mode corresponding to the current display content may be determined according to the reference magnitude range to which the target reference magnitude corresponding to the current display content belongs.
For example, the current display content includes two types of display content, i.e., a text type display content, a video type display content, a reference magnitude value corresponding to the text type display content, a weight value of 0.7, a reference magnitude value corresponding to the video type display content, a weight value of 0.3, and a reference magnitude value range corresponding to the compensation mode 1 [ a [ ] 1 ,a 2 ]The compensation pattern 2 corresponds to a reference value range [ b ] 1 ,b 2 ]Then, the target reference amount corresponding to the current display content is m ═ 0.7a +0.3b, and the reference magnitude range to which m belongs is [ a ═ a 1 ,a 2 ]Accordingly, the compensation mode corresponding to the current display content can be determined as compensation mode 1.
And step 205, determining compensation data corresponding to the liquid level fluctuation data according to the current compensation mode.
In the embodiment of the application, after the current compensation mode is determined, the compensation data corresponding to the current liquid level fluctuation data may be determined according to the liquid level fluctuation data corresponding to the current three-dimensional shaking state data and the corresponding relationship between the liquid level fluctuation data and the compensation data included in the current compensation mode.
And step 206, performing jitter display compensation on the current display content of the screen according to the compensation data.
The detailed implementation process and principle of the step 206 may refer to the detailed description of the above embodiments, and are not described herein again.
According to the anti-shaking method for screen display of the mobile terminal, the liquid level fluctuation data corresponding to the current three-dimensional shaking state data can be determined according to the acquired current three-dimensional shaking state data of the mobile terminal and the liquid container model corresponding to the mobile terminal, the current compensation mode is determined according to the type of the current display content of the screen, the compensation data corresponding to the liquid level fluctuation data is determined according to the current compensation mode, and then shaking display compensation is performed on the current display content of the screen according to the compensation data. Therefore, different compensation modes are adopted for different display contents, the position change degree of the screen display contents is reduced, the visual fatigue of human eyes is reduced, the compensation output is more attractive, and the jitter display compensation effect and the user experience are further improved.
In a possible implementation form of the embodiment of the application, smooth filtering processing can be further performed on the current three-dimensional jitter state data of the mobile terminal, so that the final compensation output is more natural and smooth, and the jitter display compensation effect is further improved.
The method for preventing shaking of screen display of a mobile terminal according to an embodiment of the present application is further described with reference to fig. 3.
Fig. 3 is a flowchart illustrating another method for displaying anti-shaking on a screen of a mobile terminal according to an embodiment of the present application.
As shown in fig. 3, the anti-shaking method for screen display of a mobile terminal includes the following steps:
The detailed implementation process and principle of step 301 may refer to the detailed description of the above embodiments, and are not described herein again.
The step of performing smooth filtering processing on the current three-dimensional jitter state data of the mobile terminal refers to a process of re-determining the current three-dimensional jitter state data according to the current three-dimensional jitter state data and three-dimensional jitter state data acquired at a plurality of moments before the current moment.
In the embodiment of the application, if the current three-dimensional shaking state data of the mobile terminal is changed more sharply than the previous time, the compensated screen display content is likely to have a suddenly changed position, and the screen display content cannot be continuously and smoothly displayed. Therefore, as a possible implementation manner, the obtained current three-dimensional jitter state data of the mobile terminal can be subjected to smooth filtering processing, so that the change amplitude of the three-dimensional jitter state data can be reasonably controlled, and the continuity of the compensated screen display content can be ensured.
Optionally, the current three-dimensional jitter state data and an average value of three-dimensional jitter state data acquired at n times before the current time may be determined as three-dimensional jitter state data after the smoothing filtering processing.
Optionally, different weight values may be respectively assigned to the current three-dimensional jitter state data and the three-dimensional jitter state data acquired at n times before the current time, and a weighted sum of the current three-dimensional jitter state data and the three-dimensional jitter state data acquired at n times before the current time is determined as the three-dimensional jitter state data after the smoothing filtering processing. In n +1 moments, the weight value corresponding to the current three-dimensional shaking state data may be the maximum value, the weight value corresponding to the three-dimensional shaking state data acquired at the previous moment adjacent to the current moment may be the second largest value, and so on.
It should be noted that, the manner of performing the smoothing filtering process on the current three-dimensional jitter state data may include, but is not limited to, the above-listed situations. In actual use, the method for performing smooth filtering processing on the current three-dimensional jitter state data and the corresponding value of n can be preset according to actual needs and experience, which is not limited in the embodiment of the present application.
And step 303, determining liquid level fluctuation data corresponding to the three-dimensional shaking state data after the smoothing filtering processing based on the liquid container model corresponding to the mobile terminal.
In the embodiment of the application, after the smooth filtering processing is performed on the current three-dimensional jitter state data of the mobile terminal, the liquid level fluctuation data corresponding to the three-dimensional jitter state data after the smooth filtering processing can be determined according to the liquid container model corresponding to the mobile terminal. The liquid level fluctuation data mode corresponding to the three-dimensional jitter state data after the smoothing filtering process is determined is the same as the liquid level fluctuation data mode corresponding to the current three-dimensional jitter state data determined in the foregoing embodiment, and the specific implementation process may refer to the detailed description of the foregoing embodiment, which is not described herein again.
And step 304, determining compensation data of the current display content of the screen according to the liquid level fluctuation data.
The detailed implementation process and principle of the step 304 may be referred to in the detailed description of the above embodiments, and are not described herein again.
