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.
The general term of the computing device that the mobile terminal can use in the moving process may include: computing devices such as cell phones, notebooks, tablet computers, digital cameras, and the like. The photographing control method disclosed by the embodiment of the invention is suitable for the mobile terminal provided with an image capturing device (such as a camera) and a shake detection device (such as an acceleration sensor and a gyroscope).
The embodiment provides a photographing control method applied to a mobile terminal, and as shown in fig. 1, the method includes: step 100 to step 120.
And step 100, acquiring the jitter amount of the mobile terminal in real time.
Generally, the photographing mode of the mobile terminal refers to a mode in which after a user enters a photographing function of the mobile terminal, an image capturing device of the mobile terminal is started to prepare for acquiring an image to be photographed. In the prior art, when a mobile terminal enters a photographing mode, if a user performs operations such as clicking a "photographing" icon or pressing a "photographing" key to issue a photographing instruction, photographing is triggered. The mobile terminal controls the image capturing device to complete photographing according to the received photographing instruction, or starts delayed photographing timing according to user setting and enters a delayed photographing mode.
In this embodiment, when the mobile terminal enters the photographing mode, and a photographing instruction sent by a photographing operation triggered by a user is detected, an operation of acquiring the shake amount of the mobile terminal in real time is started at the same time. In specific implementation, the shake amount of the mobile terminal can be acquired in real time by reading the output data of the shake detection device (such as an acceleration sensor and a gyroscope) built in the mobile terminal in real time. At the same time, the amount of jitter obtained is recorded. And continuously executing the operation of acquiring the shaking amount of the mobile terminal in real time until the mobile terminal exits from the photographing function or the photographing mode.
And step 110, if a photographing instruction is received, determining the average jitter amount of the mobile terminal based on the jitter amount acquired in real time.
And after the user clicks the picture taking icon or presses the picture taking key to trigger picture taking, the mobile terminal receives a picture taking instruction. Further, the average jitter amount of the mobile terminal is determined based on the jitter amount obtained in real time. In specific implementation, the average jitter amount is determined according to the recorded historical jitter amount data of the mobile terminal.
And step 120, controlling the execution of the photographing operation according to the average shake amount and the shake amount acquired when the photographing instruction is received.
And after the user triggers the shooting, continuously executing the operation of acquiring the jitter amount of the mobile terminal in real time, and continuously acquiring the current jitter amount of the mobile terminal. Further, whether the jitter amount acquired when the photographing instruction is received meets a preset condition is judged based on the average jitter amount. If the obtained jitter amount meets the preset condition when the photographing instruction is received, the current jitter of the mobile terminal is small and is suitable for photographing, and the mobile terminal is controlled to execute photographing operation. If the obtained jitter amount does not meet the preset condition when the photographing instruction is received, the current jitter of the mobile terminal is relatively large, the mobile terminal is controlled to carry out delayed photographing, and the timing for executing the photographing operation is further determined according to the average jitter amount and the real-time obtained jitter amount.
In the photographing control method disclosed in this embodiment, the jitter amount of the mobile terminal is obtained in real time; if a photographing instruction is received, determining the average jitter amount of the mobile terminal based on the jitter amount acquired in real time; and controlling the execution of the photographing operation according to the average jitter amount and the jitter amount acquired when the photographing instruction is received, so that the problem of fuzzy photographed pictures caused by the jitter of the mobile terminal during photographing is solved. By acquiring the jitter amount of the mobile terminal in real time and further judging whether the mobile terminal can shoot clear photos currently according to the acquired jitter amount, the execution of the shooting operation is controlled at a proper time, and the definition of the photos shot by the mobile terminal is effectively improved. The shooting time is determined by automatically judging the shaking condition of the mobile terminal instead of determining the shooting time by means of the delay time, so that the reliability of the selection of the shooting time is improved, and the definition of shot pictures is further improved. Meanwhile, the time delay for the time delay photographing set by the user is omitted, the use is convenient, and the user experience is further improved.
Referring to fig. 2, another embodiment of the present invention provides a photographing control method including: step 200 to step 260.
And 200, acquiring the jitter amount of the mobile terminal in real time.
Taking the mobile terminal as an example of the mobile phone, after a user triggers a photographing application on the mobile phone, the photographing application starts a camera of the mobile terminal to start to acquire images within a field range, and at the moment, the mobile phone is determined to enter a photographing mode. In particular, the user-triggered photographing application includes, but is not limited to, a beauty camera, a changing camera, and the like. The image capturing device includes, but is not limited to, a front camera, a rear camera.
For the digital camera, a photographing mode, a setting mode and the like are also set, and a user can enter the photographing mode through a shortcut key or through menu selection.
In the embodiment of the invention, when the mobile terminal enters the photographing mode, the operation of acquiring the shaking amount of the mobile terminal in real time is started at the same time. In specific implementation, the shake amount of the mobile terminal can be acquired in real time by reading the output data of the shake detection device (such as an acceleration sensor and a gyroscope) built in the mobile terminal in real time. And simultaneously, recording the acquired real-time jitter amount. In the mobile terminal to which the photographing control method disclosed in the embodiment of the present invention is applied, the built-in shake detection device may be a three-axis acceleration sensor, may also be three single-axis acceleration sensors that respectively detect three mutually perpendicular motion directions of the mobile terminal, may also be a gyroscope, may also be a combination of an acceleration sensor and a gyroscope, or other shake detection devices.
In this embodiment, an operation of acquiring a real-time shake amount of a mobile terminal will be described in detail by taking a shake detection apparatus as an example of three single-axis acceleration sensors provided in the mobile terminal.
For example, a plane where a display screen of the mobile terminal is located is defined as a horizontal plane, and two directions which are perpendicular to each other in the horizontal plane are respectively defined as an X-axis direction and a Y-axis direction; a direction perpendicular to the horizontal plane is defined as a Z-axis direction. Three single-axis acceleration sensors are typically provided in the mobile terminal to measure X, Y and Z-axis acceleration, respectively. And when the mobile terminal enters a photographing mode, starting to acquire the jitter amount of the mobile terminal in real time. In specific implementation, the output data of any one single-axis acceleration sensor can be acquired in real time by calling a system interface. In this embodiment, adx, ady, and adz respectively represent differences between two adjacent output data of three uniaxial acceleration sensors in the x, y, and z axis directions, and the obtained shake amount d of the mobile terminal may be represented as: d-adx2+ady2+adz2。
And continuing the operation of acquiring the jitter amount of the mobile terminal in real time along with the time until the mobile terminal exits from the photographing function or the photographing mode. In specific implementation, in order to calculate the average jitter amount subsequently, the obtained jitter amount is recorded in real time according to the sequence of the obtaining time.
The present invention does not limit the type of the jitter detection apparatus provided in the mobile terminal, and the specific method for acquiring the amount of jitter of the mobile terminal based on the jitter detection apparatus.
And after the user issues a photographing instruction by clicking the photographing icon or pressing a photographing key, determining the average jitter amount of the mobile terminal based on the jitter amount acquired in real time according to the received photographing instruction. In specific implementation, the average jitter amount is determined according to the jitter amount historical data of the mobile terminal recorded in real time. The determining an average jitter amount of the mobile terminal based on the jitter amount obtained in real time includes: determining the average jitter amount of the mobile terminal according to the historical jitter amount data; wherein the historical jitter amount data is as follows: and at least two shake amounts selected from the shake amounts acquired before the photographing instruction is received according to the sequence of the acquisition time from back to front. Generally, before a user issues a photographing instruction, the mobile terminal is kept as stable as possible, so that the shake amount of the mobile terminal does not affect photographing, therefore, the accuracy of calculating the average shake amount of the mobile terminal can be improved by determining the average shake amount according to the latest acquired shake amount historical data, the calculated average shake amount is more consistent with a shake range allowed for photographing, the accuracy of judging the photographing time is further improved, and the possibility of photographing a blurred picture is reduced.
The historical jitter amount data recorded in real time is represented as d1、d2、d3、…、dnExamples are, among others, d1、d2、d3、…、dnArranged according to acquisition time from first to last, dnFor the last acquired amount of jitter, the average amount of jitter can be determined by the following two methods.
A first method for determining an average jitter amount of a mobile terminal according to historical jitter amount data, comprising: and determining the average value of the at least two real-time jitter values as the average jitter value of the mobile terminal. In specific implementation, the formula D ═ D (D) can be determinedn+dn-1+…+dn-m+1) The average jitter amount D is calculated as/m. That is, in the jitter amounts acquired before the photographing instruction is received, an average value of at least m jitter amounts selected in an order from the last to the first according to the acquisition time is determined as an average jitter amount of the mobile terminal, where m is an integer greater than or equal to 2.
Second, determining an average jitter amount of the mobile terminal according to the historical jitter amount data includes: calculating an average value of the at least two real-time jitter values; and determining the product of the average value and a preset margin coefficient as the average jitter amount of the mobile terminal. In specific implementation, the formula D ═ D ((D) can be determinedn+dn-1+…+dn-m+1) M) f the average jitter amount D is calculated. In other words, in the jitter values obtained before the photographing instruction is received, floating the average value of at least m jitter values in a preset ratio according to at least m jitter values selected from the sequence of obtaining time from back to first, and determining the average value as the average jitter value of the mobile terminal, where m is an integer greater than or equal to 2; f is a margin coefficient, and may be a value greater than 0 according to actual needs, and preferably, f is 1.1. The historical data average value of the real-time jitter amount is adjusted by setting the margin coefficient to determine the average jitter amount, so that the accuracy of judging the photographing time can be improved, and the probability of photographing a blurred picture can be reduced.
Further, the shake amount obtained when the photographing instruction is received is further judged based on the average shake amount to determine an appropriate timing for photographing. In specific implementation, the controlling the execution of the photographing operation according to the average shake amount and the shake amount obtained when the photographing instruction is received includes: judging whether the average jitter amount and the jitter amount obtained when a photographing instruction is received meet preset conditions or not; if the average jitter amount and the jitter amount obtained when the photographing instruction is received meet the preset condition, controlling the mobile terminal to execute photographing operation; if the average jitter amount and the jitter amount obtained when the photographing instruction is received do not meet the preset condition, controlling the mobile terminal to enter a delayed photographing mode; wherein the preset conditions are as follows: the amount of jitter is less than or equal to the average amount of jitter.
When the jitter amount acquired when a photographing instruction is received is smaller than or equal to the average jitter amount, the current jitter of the mobile terminal is smaller and is suitable for photographing, and the mobile terminal is controlled to execute photographing operation; when the jitter amount acquired when the photographing instruction is received is larger than the average jitter amount, the current jitter of the mobile terminal is larger, the mobile terminal is controlled to carry out delayed photographing, and the timing for executing the photographing operation is further determined according to the average jitter amount and the jitter amount acquired in real time.
And step 230, controlling the mobile terminal to enter a delayed photographing mode.
In specific implementation, detecting whether the average jitter amount and the current jitter amount of the mobile terminal meet the preset condition and whether the photographing delay time length is greater than or equal to a preset threshold value; and if the average jitter amount and the current jitter amount are detected to meet the preset condition, or the photographing delay time is detected to be greater than or equal to a preset threshold value, controlling the mobile terminal to execute photographing operation.
And when the jitter amount of the mobile terminal is larger than the average jitter amount at the moment of receiving the photographing instruction, controlling the mobile terminal to enter a delayed photographing mode so as to wait for the jitter amount of the mobile terminal to be gradually reduced to be suitable for photographing. When the mobile terminal is in the delayed photographing mode, the operation of acquiring the shake amount of the mobile terminal in real time is continued, so that the judgment of whether the average shake amount and the shake amount acquired in real time meet the preset shake condition can be repeatedly performed, and whether the current opportunity is suitable for photographing is determined.
Meanwhile, when the mobile terminal is controlled to enter the delayed photographing mode, photographing delay timing can be started.
When the mobile terminal is in the delayed photographing mode, if the real-time acquired jitter amount of the mobile terminal is less than or equal to the average jitter amount, which indicates that the jitter amount of the mobile terminal has decreased to be suitable for photographing, the method jumps to step 260, and controls the mobile terminal to execute a photographing operation; and if the real-time jitter amount of the mobile terminal is larger than the average jitter amount, further judging the time length of the photographing delay.
And when the mobile terminal is in a delayed photographing mode, judging whether the photographing delay time is greater than or equal to a preset threshold value in real time. And when the delay time length is less than the preset threshold value, keeping in a delay photographing mode, and continuously waiting for the jitter amount of the mobile terminal to be gradually reduced to be suitable for photographing. And when the photographing delay time length is greater than or equal to a preset threshold value, immediately controlling the mobile terminal to execute photographing operation. By timing the photographing delay time, the user can be prevented from waiting for too long time, and the user experience is further improved.
And step 260, controlling the execution of the photographing operation.
In specific implementation, when the jitter amount of the mobile terminal acquired in real time is smaller than or equal to the average jitter amount, a system interface is called to control the mobile terminal to execute a photographing operation. Or, after entering the delayed photographing mode when the photographing instruction is received, delaying the preset time length to wait for the mobile terminal to be stable, and controlling the mobile terminal to execute the photographing operation even though the current shake amount of the mobile terminal may be larger than the average shake amount, so as to avoid that the user waits for too long time, improve the photographing efficiency, and improve the user experience at the same time.
By this, one photographing control operation is ended.
In specific implementation, when the mobile terminal is in the delayed photographing mode, the photographing delay can be judged first, and the jitter amount can also be judged first.
Preferably, in another preferred implementation manner of this embodiment, when the jitter amount of the mobile terminal obtained in real time is greater than the average jitter amount, after controlling the mobile terminal to enter the delayed shooting mode, the method further includes: and displaying prompt information, wherein the prompt information is used for prompting a user to reduce the jitter of the mobile terminal.
During specific implementation, the prompt information can be displayed in modes of voice or interface flashing or display of prompt characters and the like, and a user is reminded of reducing the touch, pressing or shaking force of the mobile terminal, so that the user is prompted to reduce the shaking of the mobile terminal. Through prompting the user, after the user takes measures in time, the photographing efficiency can be improved, and meanwhile, the definition of photographed pictures can be further improved.
In the photographing control method disclosed in this embodiment, the jitter amount of the mobile terminal is obtained in real time; then, when a photographing instruction is received, determining the average jitter amount of the mobile terminal based on the jitter amount acquired in real time; and determining the photographing time according to the average jitter amount and the jitter amount obtained by receiving the photographing instruction so as to control the mobile terminal to execute the photographing operation, thereby solving the problem of fuzzy photographed pictures caused by the jitter of the mobile terminal during photographing. When the real-time jitter amount of the mobile terminal is large, the mobile terminal is controlled to enter a delayed photographing mode, photographing time is further determined according to the real-time jitter amount and the photographing delay time, and the definition of a photo photographed by the mobile terminal is effectively improved. Meanwhile, the shaking condition of the mobile terminal is automatically judged, and the shooting time is determined by combining the preset time delay shooting duration, so that the reliability of the selection of the shooting time is improved, the user can not wait for too long time, and the user experience is further improved.
