Description
Technical Field
The present invention relates to the field of photography technologies, and in particular, to a method, an apparatus, and a system for entering a camera interface.
Background
With the development of the photographing technology, cameras are installed in mobile terminals such as mobile phones and tablet computers. When a user needs to photograph an object, the camera is started through the mobile terminal, and therefore the user enters a camera interface to photograph or make a video. In the process of taking a picture or video, time may be critical, and when an emergency or emergency event is happening, a user may capture a picture or video of the event for only a short moment, and therefore, the camera interface entry method is particularly important.
The existing camera interface entering method includes a method of setting a shortcut key for entering the camera interface on a screen locking interface of the mobile terminal or a method of quickly entering the camera interface by separately setting a physical entity shortcut key on the mobile terminal. The method for setting the shortcut key for entering the camera interface on the screen locking interface of the mobile terminal specifically comprises the steps that when a user needs to capture an object, the user takes the mobile terminal out of a pocket or a handbag and the like, transfers the mobile terminal to a shooting position, then sequentially presses down a power key to light a screen, finally finds the shortcut key, and triggers the shortcut key to enter the camera interface. Or when the user needs to capture an object, the user firstly triggers an unlocking setting, such as fingerprint unlocking, unlocks and lights the screen, then finds the shortcut key and triggers the shortcut key to enter a camera interface in the process that the mobile terminal is transferred to the shooting position. The method for independently setting the physical entity shortcut key on the mobile terminal to quickly enter the camera interface specifically comprises the steps that when a user needs to capture an object, the user takes the mobile terminal out of a pocket or a handbag, transfers the mobile terminal to a shooting position, finds the physical entity shortcut key, and finally presses the physical entity shortcut key to enter the camera interface.
The camera interface entering method in the prior art has certain disadvantages, for example, in the case of time emergency, a user needs to go through multiple steps to successfully enter the camera interface to shoot or pick up the image after the user wants to shoot the image to actually start shooting, the time cost is long, the key information shooting is incomplete or missed, unnecessary loss is possibly caused, and the user experience is poor.

Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.
Referring to fig. 1, which is a flowchart illustrating an implementation of a camera interface entering method according to the present invention, the method may include the following steps:
step S101: and when the mobile terminal is detected to reach a preset speed threshold, generating an internal trigger signal.
A speed threshold may be preset for the mobile terminal, and when it is detected that the moving speed of the mobile terminal reaches the preset speed threshold, it may be regarded that a preset trigger condition is reached, and in this case, the internal trigger signal may be generated.
It should be noted that the speed threshold may be set and adjusted according to actual situations, which is not limited in the embodiment of the present invention. For example, the technical solution provided by the embodiment of the present invention is executed for a plurality of times according to a certain speed threshold, but when a user uses a mobile terminal to capture an object, the phenomenon that the mobile terminal does not automatically enter a camera interface is still frequent, and the speed threshold can be appropriately reduced.
Step S102: and obtaining an acceleration characteristic value and an angular velocity characteristic value of the mobile terminal according to the internal trigger signal.
After the internal trigger signal is generated, it may be predicted that the user needs to take a picture of a peripheral object by using the mobile terminal. Therefore, in this case, the acceleration characteristic value and the angular velocity characteristic value of the mobile terminal may be obtained from the generated internal trigger signal.
Step S103: and determining whether to generate a camera call signal according to the acceleration characteristic value and the angular velocity characteristic value, and if so, executing step S104.
After the acceleration characteristic value and the angular velocity characteristic value of the mobile terminal are obtained, the translation and rotation conditions of the mobile terminal can be determined according to the obtained acceleration characteristic value and the obtained angular velocity characteristic value, whether the prejudgment that a user possibly utilizes the mobile terminal to photograph surrounding objects is correct or not is verified, so that whether a camera calling signal is generated or not is determined, and if the camera calling signal is determined to be generated, the step S104 can be continuously executed. If it is determined that the camera call signal is not generated, the next detection is not performed.
In one embodiment of the present invention, step S103 may include the following steps:
the method comprises the following steps: determining whether the acceleration characteristic value is larger than a preset acceleration threshold value and the angular speed characteristic value is larger than a preset first angular speed threshold value, if so, executing a second step;
step two: determining whether the timing time is less than a preset first time threshold value or not from a first moment when the acceleration characteristic value is greater than the acceleration threshold value and the angular velocity characteristic value is greater than the first angular velocity threshold value to a moment when the first angular velocity characteristic value of the angular velocity characteristic value in the X-axis direction or the second angular velocity characteristic value of the angular velocity characteristic value in the Y-axis direction is less than a preset second angular velocity threshold value;
the X-axis direction and the Y-axis direction are corresponding directions in a space rectangular coordinate system established by taking the edge of the mobile terminal as the X axis, the Y axis and the Z axis.
For convenience of description, the above two steps may be combined for illustration.
The acceleration threshold and the first angular velocity threshold of the mobile terminal can be preset, the acceleration characteristic value and the angular velocity characteristic value of the mobile terminal can be obtained in real time in the moving process of the mobile terminal, whether the acceleration characteristic value is larger than the acceleration threshold and the angular velocity characteristic value is larger than the first angular velocity threshold exists in the moving process of the mobile terminal from the original position or not is determined, and if the acceleration characteristic value is larger than the acceleration threshold and the angular velocity characteristic value is larger than the first angular velocity threshold, the possibility that a user who makes a further judgment possibly uses the mobile terminal to photograph surrounding objects is judged to be correct.
The edge of the mobile terminal may be used as an X axis, a Y axis, and a Z axis to establish a spatial rectangular coordinate system, for example, a short side of the mobile phone may be used as the X axis, a long side may be used as the Y axis, and a side between the short side and the long side and representing the thickness may be used as the Z axis to establish the spatial rectangular coordinate system. And a second angular velocity threshold of the mobile terminal can be preset, timing can be started from a first time point when the acceleration characteristic value is greater than the preset acceleration threshold and the angular velocity characteristic value is greater than the preset first angular velocity threshold, and when the first angular velocity characteristic value of the mobile terminal in the X-axis direction or the second angular velocity characteristic value of the mobile terminal in the Y-axis direction is less than the preset second angular velocity threshold, whether the timing time is less than the preset first time threshold, that is, whether the mobile terminal has a trend from moving to being stationary, cannot only judge whether the acceleration characteristic value is greater than the acceleration threshold and the angular velocity characteristic value is greater than the first angular velocity threshold, because the user is not in need of taking a snapshot of the object, for example, when the user is running with the mobile terminal, the situation that the acceleration characteristic value of the mobile terminal is greater than the acceleration threshold and the angular velocity characteristic value is greater than the first angular velocity threshold may also occur, when a user uses the mobile terminal to capture an object, the mobile terminal has a deceleration process within a certain time from an original position to a shooting position, and after the mobile terminal decelerates to the shooting position, the mobile terminal is in a horizontal screen state or a vertical screen state, wherein the horizontal screen state is that the angle change of the mobile terminal in the X-axis direction is basically zero or changes within a small range, and the vertical screen state is that the angle change of the mobile terminal in the Y-axis direction is basically zero or changes within a small range.
It should be noted that, both the acceleration threshold and the first angular velocity threshold are values greater than zero, and both of them may be set and adjusted according to actual situations, which is not limited in the embodiment of the present invention. For example, when the technical solution provided by the embodiment of the present invention is executed multiple times according to a certain set acceleration threshold and a certain set first angular velocity threshold, but if the phenomenon that the mobile terminal does not automatically enter the camera interface is still frequent when the user uses the mobile terminal to capture an object, the set acceleration threshold or the set first angular velocity threshold may be appropriately reduced, so as to reduce the probability that the mobile terminal does not automatically enter the camera interface when the user uses the mobile terminal to capture the object due to the fact that the set acceleration threshold or the set first angular velocity threshold is too large.
It should be further noted that the first time threshold may be set and adjusted according to actual situations, which is not limited in the embodiment of the present invention. For example, when the technical solution provided by the embodiment of the present invention is executed multiple times according to a certain set first time threshold, but when a user uses a mobile terminal to capture an object, because when the timing time reaches the first time threshold, both the first angular velocity characteristic value of the mobile terminal in the X-axis direction and the second angular velocity characteristic value of the mobile terminal in the Y-axis direction are not less than the second angular velocity threshold, and the phenomenon that the mobile terminal does not automatically enter the camera interface is still frequent, the first time threshold may be increased.
It should be further noted that the second angular velocity threshold may be set and adjusted according to an actual situation, which is not limited in the embodiment of the present invention, for example, when the technical solution provided by the embodiment of the present invention is executed multiple times according to a certain set second angular velocity threshold, but when a user does not use the mobile terminal to capture an object, the phenomenon that the mobile terminal automatically enters the camera interface is still more frequent, and the second angular velocity threshold may be reduced.
In an embodiment of the present invention, determining whether the timing time is less than a preset first time threshold may include the following steps:
and determining whether the timed time is less than a preset first time threshold and the duration of the first angular speed characteristic value or the second angular speed characteristic value which is less than the second angular speed threshold is greater than a preset second time threshold.
After determining that there is a case where the acceleration characteristic value of the mobile terminal is greater than the acceleration threshold and the angular velocity characteristic value is greater than the first angular velocity threshold, and determining that the time is counted from a first time when the acceleration characteristic value of the mobile terminal is greater than the acceleration threshold and the angular velocity characteristic value is greater than the first angular velocity threshold, to a time when the first angular velocity characteristic value of the mobile terminal in the X-axis direction or the second angular velocity characteristic value of the mobile terminal in the Y-axis direction is less than the second angular velocity threshold, it may be further determined whether a duration of the time when the first angular velocity characteristic value of the mobile terminal in the X-axis direction or the second angular velocity characteristic value of the mobile terminal in the Y-axis direction is less than the second angular velocity threshold is greater than a preset second time. When a user takes a snapshot of an object, the user may want to switch the screen state after the mobile terminal reaches the shooting position from the original position, for example, switch from the landscape screen state to the portrait screen state, and therefore, after determining that the first angular velocity characteristic value of the mobile terminal in the X-axis direction or the second angular velocity characteristic value of the mobile terminal in the Y-axis direction is smaller than the second angular velocity threshold value, a certain time is needed to wait.
It should be noted that the second time threshold may be set and adjusted according to actual situations, which is not limited in the embodiment of the present invention. For example, when the technical solution provided by the embodiment of the present invention is executed for a plurality of times according to a certain second time threshold set by the embodiment of the present invention, however, after the user moves the mobile terminal from the original position to the shooting position, the user wants to switch the screen state shooting, and before the screen is switched, the phenomenon that the mobile terminal shoots an object frequently occurs, the second time threshold may be increased.
Step S104: and generating a camera calling signal, and calling the camera to enter a camera interface by using the camera calling signal.
After a camera call signal is generated according to the acceleration characteristic value and the first angular velocity characteristic value, a camera of the mobile terminal can be called to enter a camera interface by the camera call signal.
By applying the method provided by the embodiment of the invention, when the moving speed of the mobile terminal is detected to reach the preset speed threshold, the internal trigger signal is generated, the acceleration characteristic value and the angular speed characteristic value of the mobile terminal are obtained according to the internal trigger signal, whether the camera calling signal is generated or not is determined according to the acceleration characteristic value and the angular speed characteristic value, if so, the camera calling signal is generated, and the camera calling signal is used for calling the camera to enter the camera interface. The acceleration characteristic value and the angular speed characteristic value of the mobile terminal are obtained when the moving speed of the mobile terminal reaches the preset speed threshold value, after a camera calling signal is judged and generated according to the acceleration characteristic value and the angular speed characteristic value, the camera calling signal can be utilized to call the camera to enter the camera interface, therefore, when a user needs to take a snapshot of an object, the camera interface can be automatically entered, the step of entering the camera interface is simplified, time is saved, the phenomenon that key information is not shot completely or missed in shooting can be reduced, unnecessary loss is reduced, and user experience is improved.
In an embodiment of the present invention, after step S104, the method may further include the steps of:
the method comprises the following steps: determining whether an instruction of photographing or shooting by a user is received within a preset third time threshold from the moment when the camera enters the camera interface, and if not, executing the second step;
step two: and determining that the operation of calling the camera to enter the camera interface by using the camera calling signal is misoperation so as to enable the mobile terminal to automatically lock the screen.
For convenience of description, the above two steps may be combined for illustration.
A third time threshold may be preset, after the generated camera call signal is used to call the camera of the mobile terminal to enter the camera interface, it may be determined whether an instruction for taking a picture or taking a video by the user is received within the preset third time threshold since the camera enters the camera interface, if so, the camera continues to take a picture or take a video, and if not, it is determined that the operation of calling the camera to enter the camera interface by the camera call signal is a misoperation, and the mobile terminal automatically locks the screen.
It should be noted that the third time threshold may be set and adjusted according to actual situations, which is not limited in the embodiment of the present invention. For example, when the technical solution provided by the embodiment of the present invention is executed multiple times according to a certain set third time threshold, but when a user uses the mobile terminal to capture an object, because the set third time threshold is too short, the phenomenon that the mobile terminal automatically locks the screen frequently occurs because the camera enters the camera interface and no instruction of the user to take a picture or take a video is received within the third time threshold, and the third time threshold may be increased.
Referring to fig. 2, which is a flowchart of another implementation of a camera interface entering method according to an embodiment of the present invention, the method may include the following steps:
s201: and when the mobile terminal is detected to reach a preset speed threshold value, the processor generates an internal trigger signal.
S202: the acceleration sensor and the gyroscope sensor receive internal trigger signals, the acceleration sensor detects an acceleration characteristic value of the mobile terminal, and the gyroscope sensor detects an angular speed characteristic value of the mobile terminal and sends the acceleration characteristic value and the angular speed characteristic value to the processor.

S207: and judging whether the mobile terminal is in a vertical screen state or is converted into a horizontal screen state within a second time threshold, if so, executing the step S208, otherwise, the mobile terminal is in a screen locking state, and the mobile terminal is unlocked in the original mode.
The processor judges whether the timing is started from the fact that the detected acceleration characteristic value is larger than the acceleration threshold value and the angular velocity characteristic value is larger than the first angular velocity threshold value, when the received first angular velocity characteristic value of the angular velocity characteristic value sent by the gyroscope sensor in the X-axis direction or the second angular velocity characteristic value of the angular velocity characteristic value sent by the gyroscope sensor in the Y-axis direction is smaller than the preset second angular velocity threshold value, whether the timing time is smaller than the preset first time threshold value is judged, namely whether the mobile terminal is in the vertical screen state or the horizontal screen state is judged, whether the time that the first angular velocity characteristic value or the second angular velocity characteristic value is smaller than the second angular velocity threshold value is larger than the preset second time threshold value is judged, namely whether the screen state is converted after the mobile terminal reaches the shooting position from the original position is judged. And step S208 is executed after the final screen state before shooting is determined, otherwise, the mobile terminal is in the screen locking state and is unlocked in the original mode.
S208: the processor generates a camera call signal to call the camera to enter the camera interface.
S209: and the processor detects the condition of a photographing or shooting instruction received within a preset third time threshold from the moment that the camera enters the camera interface.
S210: and judging whether the mobile terminal takes a picture or a video within a time threshold value, if so, executing the step S211, otherwise, enabling the mobile terminal to be in a screen locking state, and unlocking the mobile terminal according to the original mode.
S211: the camera continues to take pictures or take pictures.
