The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The Mobile terminal according to the embodiment of the present invention may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like, which have wireless communication functions. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.
Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1A, fig. 1A is a schematic flowchart of a photographing control method applied to a mobile terminal according to an embodiment of the present invention, and as shown in the drawing, the photographing control method includes:
s101, the mobile terminal obtains first posture information of the mobile terminal, and the mobile terminal is in a screen-off state.
The screen-off state means that the mobile terminal is in a screen-off standby state, when the mobile terminal is awakened normally, if a user presses a power key to light a screen, the mobile terminal can display a screen locking interface and perform identity recognition operation, and when the user passes recognition through recognition modes such as fingerprints, the mobile terminal releases the screen locking interface to display a system desktop for normal use of the user.
S102, when detecting that first posture information of the mobile terminal is matched with posture information in a preset posture information set, the mobile terminal acquires duration of the mobile terminal in a relatively static state, and change of the posture information of the mobile terminal in the relatively static state relative to the first posture information is smaller than a preset threshold value.
The preset threshold may be set by a system or a user, and is not limited herein.
And S103, when detecting that the duration of the relative static state of the mobile terminal is greater than or equal to a preset duration threshold, the mobile terminal displays a shooting interface of a shooting application of the mobile terminal.
The preset time length threshold may be set by a system or a user, and is not limited herein.
As shown in fig. 1B, the shooting interface of the shooting application displayed by the mobile terminal may include not only the environment image information currently captured by the camera device, but also a plurality of components, where the plurality of components include a historical photograph browsing component.
In one possible example, after the mobile terminal displays a shooting interface of a shooting application of the mobile terminal, the method further includes: the mobile terminal identifies whether the current user is a registered user; when the mobile terminal identifies that the current user is not a registered user, the historical photo browsing component does not relate to photos in the photo library of the mobile terminal, when the mobile terminal identifies that the current user is the registered user, the historical photo browsing component relates to at least one photo in the photo library of the mobile terminal, and when the mobile terminal detects a selection operation aiming at the historical photo browsing component, the mobile terminal displays the photos related to the historical photo browsing component.
The method for identifying whether the current user is a registered user by the mobile terminal comprises the following steps: the mobile terminal captures the face data of the current user in a hidden mode through the front-facing camera, and compares the face data with the face template to identify whether the current user is a registered user or not.
It can be seen that, in the embodiment of the present invention, the mobile terminal first obtains the first posture information of the mobile terminal, then obtains the duration of the mobile terminal in the relatively static state when detecting that the first posture information of the mobile terminal matches the posture information in the preset posture information set, and then displays the shooting interface of the shooting application of the mobile terminal when detecting that the duration of the mobile terminal in the relatively static state is greater than or equal to the preset duration threshold. The mobile terminal is in a screen-off state, that is, the mobile terminal does not need to execute response operation in steps to display a shooting interface, (the step-by-step execution of the response operation specifically includes responding to the operation of lighting the display screen of the user, such as pressing a power key, and then responding to the operation of starting the shooting application of the user, such as clicking a shooting application icon of a frequency-locking interface, and the like), and the convenience and the efficiency of controlling the shooting application by the mobile terminal are improved.
In a possible example, the above-mentioned shooting interface for displaying the shooting application of the mobile terminal includes: and lightening a display screen, running the photographing application of the mobile terminal, starting a camera device and displaying a photographing interface of the photographing application.
Therefore, in this example, the mobile terminal can autonomously perform operations of lighting the display screen, running the photographing application, starting the camera device, and displaying a series of photographing interfaces of the photographing application, without triggering by excessive redundant operations of a user, which is beneficial to improving convenience and intelligence of directly starting the photographing function from the screen off state of the mobile terminal.
In a possible example, the above-mentioned shooting interface for displaying the shooting application of the mobile terminal includes: acquiring a motion track of the mobile terminal in a preset time period; and when the motion track is matched with the preset track, lightening a display screen, running the photographing application of the mobile terminal, starting a camera device and displaying a photographing interface of the photographing application.
The time starting point of the preset time period may be a moment when the mobile terminal detects that the first posture information matches with the posture information in the preset posture information set, the motion trajectory refers to a trajectory formed by the mobile terminal in the moving process of the preset time period, the preset trajectory includes, but is not limited to, a circle, an ellipse, a triangle, a square, a line segment and the like, the preset trajectory may be provided with a trajectory entry function by the mobile terminal, and a user actively enters the trajectory through the trajectory entry function (for example, prompting the user to move the mobile terminal to obtain a corresponding trajectory, and the user enters the trajectory after confirmation, this way enhances user interaction, and is highly interesting in setting), or directly selects the trajectory (for example, directly outputting multiple trajectories for the user to select, this way is more convenient and intuitive, and is highly efficient in setting), and is not limited here.
The "matching" may be understood as that the mobile terminal detects that the motion trajectory substantially matches the preset trajectory or the error is within a preset error threshold (the preset error threshold may be set by a system or by a user), which is not limited herein.
As can be seen, in this example, since the mobile terminal lights up the display screen, runs the photographing application of the mobile terminal, starts the camera device, and displays the photographing interface of the photographing application when detecting that the motion trajectory within the preset time period matches the preset trajectory, the situation that the user does not actively operate the mobile terminal to mistakenly trigger the mobile terminal to display the photographing interface can be avoided, and the accuracy of starting the photographing function of the mobile terminal from the screen-off state can be improved.
In a possible example, the above-mentioned shooting interface for displaying the shooting application of the mobile terminal includes:
executing a first operation and a second operation in parallel, wherein the first operation is to acquire a motion track of the mobile terminal in a preset time period, and the second operation is to run a photographing application of the mobile terminal and start a camera device;
and when the motion track is matched with a preset track, lightening a display screen and displaying a shooting interface of the shooting application.
Therefore, in this example, the mobile terminal saves the operation time through parallel operation, reduces the total time for directly starting the photographing function from the screen-off state of the mobile terminal, and is beneficial to improving the response speed for controlling the photographing function to be started by the mobile terminal.
In a possible example, the obtaining of the motion trajectory of the mobile terminal within the preset time period includes:
acquiring a plurality of second posture information of the mobile terminal in the preset time period;
and determining the motion trail of the mobile terminal in the preset time period according to the first posture information and the plurality of second posture information.
The mobile terminal can sample the attitude information of the mobile terminal according to a certain frequency (for example, 5 times/s) within a preset time period through built-in or externally connected sensing devices such as a gyroscope, an accelerometer, an electronic compass and the like, so as to respectively obtain the attitude value at each sampling time. The preset time period may be set by the system or set by the user as needed, and is not specifically limited herein.
In one possible example, the obtaining the first posture information of the mobile terminal includes:
acquiring an angular velocity value and a first Euler angle attitude value at a first sampling moment;
calculating four-element attitude values at the first sampling time according to a first Euler angle attitude value at the first sampling time;
predicting a first attitude value at a second sampling time according to the angular velocity value at the first sampling time and the four-element attitude value at the first sampling time, wherein the first sampling time and the second sampling time are adjacent sampling times, and the first sampling time is earlier than the second sampling time;
acquiring a second Euler angle attitude value at the second sampling moment;
and correcting the first attitude value according to the second euler angle attitude value, and using the corrected first attitude value as the first attitude information of the second sampling time.
And predicting the first attitude value of the second sampling moment by the following formula:
Therefore, in this example, the attitude value at the second sampling time is predicted according to the angular velocity value at the first sampling time and the four-element attitude value, and the predicted attitude value is corrected according to the second euler angular attitude value at the second sampling time to obtain high-precision attitude information, so that the photographing function is accurately triggered from the screen-off state when the mobile terminal is relatively static, and the accuracy of the mobile terminal responding to the user to start the photographing function is improved.
In a possible example, the lighting a display screen, running a photographing application of the mobile terminal, starting a camera device, and displaying a photographing interface of the photographing application includes:
paralleling a third operation and a fourth operation, wherein the third operation is to light up a display screen, and the fourth operation is to run a photographing application of the mobile terminal and start a camera; or, the third operation is to light up a display screen and start a camera, and the fourth operation is to run a photographing application of the mobile terminal;
and displaying a shooting interface of the shooting application.
Therefore, in this example, the mobile terminal reduces the processing time by performing the third operation and the fourth operation in parallel, which is beneficial to improving the response speed of starting the photographing function from the screen-off state.
In one possible example, before the obtaining the first posture information of the mobile terminal, the method further includes:
acquiring a historical photographing record of a user;
and generating the preset attitude information set according to the historical photographing record.
Therefore, in the example, the mobile terminal counts the photographing posture of the user habit according to the historical photographing record, and forms the posture information set according to the photographing posture, so that the use habit of the user can be signed when the follow-up user actively triggers the photographing function, the error rate is reduced, and the accuracy of starting the photographing function from the screen-off state of the mobile terminal is improved.
Referring to fig. 2, fig. 2 is a schematic flowchart of a photographing control method according to an embodiment of the present invention, and the photographing control method is applied to a mobile terminal. As shown in the figure, the photographing control method comprises the following steps:
s201, the mobile terminal acquires first posture information of the mobile terminal, and the mobile terminal is in a screen-off state.
S202, when detecting that the first posture information of the mobile terminal is matched with the posture information in the preset posture information set, the mobile terminal acquires the duration of the mobile terminal in the relative static state, wherein the change of the posture information of the mobile terminal in the relative static state relative to the first posture information is smaller than a preset threshold value.
And S203, when detecting that the duration of the relative static state of the mobile terminal is greater than or equal to a preset duration threshold, the mobile terminal executes a first operation and a second operation in parallel, wherein the first operation is to acquire a motion track of the mobile terminal in a preset time period, and the second operation is to run a photographing application of the mobile terminal and start a camera device.
And S204, when the mobile terminal detects that the motion track is matched with a preset track, lightening a display screen and displaying a shooting interface of the shooting application.
It can be seen that, in the embodiment of the present invention, the mobile terminal first obtains the first posture information of the mobile terminal, then obtains the duration of the mobile terminal in the relatively static state when detecting that the first posture information of the mobile terminal matches the posture information in the preset posture information set, and then displays the shooting interface of the shooting application of the mobile terminal when detecting that the duration of the mobile terminal in the relatively static state is greater than or equal to the preset duration threshold.

In addition, the mobile terminal saves the operation time through parallel operation, reduces the total time for directly starting the photographing function from the screen-off state of the mobile terminal, and is favorable for improving the response speed for controlling the photographing function to be started by the mobile terminal.
