Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. 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 application.
With the development of science and technology, more and more functions can be supported by the terminal. For example, a user may use the terminal to watch television or use the terminal to make a video call with another person. When a user watches videos by using the terminal, the user can rotate the terminal, and a display picture of the terminal can rotate in the reverse direction, so that the display picture of the terminal can be kept vertically downward, and the user can watch televisions more comfortably.
Now, fig. 1 illustrates an application scenario diagram of a picture rotation control method applied to an embodiment of the present application. As shown in fig. 1, when the terminal is at rest, the resultant force applied to the terminal may be only gravity. The terminal can calculate the rotation angle of the terminal by using the formula (1) and the formula (2) based on the six-axis sensor.
Figure BDA0002383319280000051
Figure BDA0002383319280000052
Wherein, gxIs the component of acceleration in the x-axis; gyIs the component of acceleration in the y-axis; gzComponent of acceleration in the z-axis αxComponent of angular velocity in the x-axis αyComponent of angular velocity in the y-axis αzIs the component of angular velocity in the z-axis.
For example, the gravity borne by the terminal of 125g when the terminal is at rest is 1.25N, and the rotation angle of the terminal along the clockwise direction is 35 degrees as calculated by the terminal according to the formula (1) and the formula (2). The terminal may acquire that the rotation angle of the display screen is 35 degrees in the counterclockwise direction based on the rotation angle of the terminal of 35 degrees. The terminal may rotate the display based on the calculated rotation angle of the display so that the display of the terminal may be maintained vertically downward while the terminal is rotated.
According to some embodiments, the terminal may be shaken due to other external forces applied to the terminal during the rotation of the terminal. Other external forces include, but are not limited to, thrust, pressure, friction, and the like. Because the calculation method based on the six-axis sensor only considers the gravity borne by the terminal and does not relate to the condition that the terminal has jitter, the calculation of the rotation angle of the terminal is inaccurate by the terminal rotation angle calculation method based on the six-axis sensor, the jitter still exists in the terminal to influence the rotation angle of a display picture of the terminal, and further the display effect of the display picture is influenced.
Fig. 2 is a flowchart illustrating a screen rotation control method according to an embodiment of the present application.
As shown in fig. 2, the screen rotation control method includes:
s101, when the terminal rotates along the first rotation direction, whether the terminal deviates along a second rotation direction is judged, and the second rotation direction is the reverse direction of the first rotation direction.
According to some embodiments, the first rotation direction refers to a rotation direction of the terminal, wherein the first rotation direction refers to only one of the rotation directions, and does not refer to a specific rotation direction. The second rotation direction is the reverse direction of the first rotation direction, wherein the second rotation direction refers to only one of the rotation directions, and does not refer to a specific rotation direction. As shown in fig. 3, the first rotation direction of the terminal may be, for example, a clockwise rotation direction V1 centering on the center of the terminal display screen, and the second rotation direction of the terminal may be, for example, a counterclockwise rotation direction V2 centering on the center of the terminal display screen. The center of the display screen of the terminal may be, for example, an intersection of diagonal lines of the display screen, or a center point preset by the terminal.
It is easily understood that the terminal may determine whether the terminal is shifted in the second rotation direction when the terminal is rotated in the first rotation direction. For example, when the terminal rotates in the clockwise rotation direction V1 around the center of the terminal display screen, the terminal can determine whether the terminal is shifted in the counterclockwise rotation direction V2.
Optionally, when the terminal rotates in the first rotation direction, a flag of the check valve may be set, so that the terminal may mark the rotation direction of the terminal. The terminal can judge whether the terminal deviates along the second rotation direction through the zone bit of the one-way valve. When the terminal judges that the terminal does not deviate along the second rotation direction through the zone bit of the one-way valve, the terminal can continue to rotate along the first rotation direction.
And S102, if yes, acquiring a first rotation parameter of the terminal.
According to some embodiments, the first rotation parameter comprises a third rotation direction and a first rotation angle. The third rotation direction refers to a rotation direction of the terminal, but is not particularly limited to a specific rotation direction. The first rotation angle refers to a rotation angle of the terminal in the third rotation direction. The third direction of rotation may be the same direction as the second direction of rotation, and the third direction of rotation may also be the same as the first direction of rotation, for example. The terminal may acquire a third rotation direction of the terminal based on an offset amount of the terminal in the second rotation direction and the rotation start angle. For example, when the terminal rotates in the first rotation direction, and the offset of the terminal in the second rotation direction is smaller than the rotation start angle, the third rotation direction acquired by the terminal is the same as the first rotation direction, and when the first rotation direction is clockwise, the third rotation direction is also clockwise.
It is easily understood that when the terminal is rotated in the first rotation direction, the offset amount of the terminal in the second rotation direction is greater than the rotation start angle, the terminal acquires the third rotation direction as the same as the second rotation direction, and when the second rotation direction is the counterclockwise direction, the third rotation direction is also the counterclockwise direction.
Optionally, when the terminal rotates in the first rotation direction, the terminal may determine whether the terminal is offset in the second rotation direction. The second rotation direction is the reverse direction of the first rotation direction. When the terminal judges that the terminal deviates along the second rotation direction, the terminal determines that the terminal shakes, and at the moment, the terminal can acquire the first rotation parameter of the terminal. For example, the terminal may acquire the third rotation direction of the terminal based on the offset amount and the rotation start angle of the terminal in the second rotation direction. The rotation start angle set by the terminal may be, for example, 2 degrees. When the terminal rotates in the clockwise direction, the terminal detects that the terminal is shifted in the counterclockwise direction by 5 degrees. The terminal determines that the offset amount is 5 degrees greater than the rotation start angle by 2 degrees, so that the terminal determines that the terminal has offset in the counterclockwise direction, and the terminal acquires a first rotation parameter of the terminal, where the first rotation parameter may be, for example, that the third rotation direction is the counterclockwise direction, and the first rotation angle is 5 degrees.
S103, determining a second rotation parameter of the display screen of the terminal based on the first rotation parameter.
According to some embodiments, the second rotation parameter comprises a fourth rotation direction and the second rotation angle, wherein the fourth rotation direction is the reverse direction of the third rotation direction. The second rotation angle is a rotation angle of the display screen determined by the terminal along the fourth rotation direction. The third direction of rotation may be the same direction as the second direction of rotation, and the third direction of rotation may also be the same as the first direction of rotation, for example. For example, the terminal may acquire the third rotation direction of the terminal based on the offset amount and the rotation start angle of the terminal in the second rotation direction. When the terminal rotates along the first rotation direction, and the offset of the terminal along the second rotation direction is smaller than the rotation start angle, the third rotation direction acquired by the terminal is the same as the first rotation direction, and when the first rotation direction is a clockwise direction, the third rotation direction is also a clockwise direction, and then the fourth rotation direction of the display picture of the terminal is an anticlockwise rotation direction.
It is easy to understand that when the terminal determines that the terminal is shifted in the second rotation direction, the terminal may obtain the first rotation parameter of the terminal. Based on the first rotation parameter, the terminal may determine a second rotation parameter of a display of the terminal. The rotation start angle set by the terminal may be, for example, 2 degrees. When the terminal rotates in the clockwise direction, the terminal detects that the terminal is shifted in the counterclockwise direction by 5 degrees. The terminal determines that the offset amount is 5 degrees greater than the rotation start angle by 2 degrees, so that the terminal determines that the terminal has offset in the counterclockwise direction, and the terminal acquires a first rotation parameter of the terminal, where the first rotation parameter may be, for example, that the third rotation direction is the counterclockwise direction, and the first rotation angle is 5 degrees. The terminal determines the second rotation parameter of the display screen of the terminal based on the first rotation parameter, for example, the fourth rotation direction of the display screen of the terminal is clockwise, and the second rotation angle is 5 degrees.
And S104, rotating the display picture based on the second rotation parameter.
According to some embodiments, when the terminal determines that the terminal is shifted in the second rotation direction, the terminal may acquire the first rotation parameter of the terminal. Based on the first rotation parameter, the terminal may determine a second rotation parameter of a display of the terminal. When the terminal determines the second rotation parameter of the display of the terminal, the terminal may rotate the display of the terminal based on the second rotation parameter.
It is easily understood that when the terminal determines that the terminal is shifted in the second rotation direction, the display interface of the terminal may be as shown in fig. 4. The rotation start angle set by the terminal may be, for example, 2 degrees. When the terminal rotates in the clockwise direction, the terminal detects that the terminal is shifted in the counterclockwise direction by 5 degrees. The terminal determines that the offset is 5 degrees and greater than the rotation start angle by 2 degrees, the terminal may determine that the terminal has offset in the counterclockwise direction, and the terminal acquires a first rotation parameter of the terminal, where the first rotation parameter may be, for example, that the third rotation direction is the counterclockwise direction, and the first rotation angle is 5 degrees. The terminal determines, based on the first rotation parameter, that the second rotation parameter of the display screen of the terminal is that the fourth rotation direction of the display screen of the terminal is clockwise, and when the second rotation angle is 5 degrees, the terminal may rotate the display screen of the terminal by 5 degrees in the clockwise direction. The display interface of the terminal after rotating the display screen of the terminal can be as shown in fig. 5.
The embodiment of the application provides a picture rotation control method, which can judge whether a terminal deviates along a second rotation direction when the terminal rotates along the first rotation direction, wherein the second rotation direction is the reverse direction of the first rotation direction, if so, a first rotation parameter of the terminal is obtained, the first rotation parameter comprises a third rotation direction and a first rotation angle, a second rotation parameter of a display picture of the terminal can be determined based on the first rotation parameter, the second rotation parameter comprises a fourth rotation direction and a second rotation angle, the fourth rotation direction is the reverse direction of the third rotation direction, and the display picture is rotated based on the second rotation parameter. Therefore, when the terminal rotates along the first rotation direction and deviates along the second rotation direction, the terminal can shake, the terminal acquires the second rotation parameter of the terminal display picture based on the first rotation parameter, the influence of the terminal shake on the second rotation parameter can be reduced, the accuracy of rotation parameter calculation can be improved, the influence of the terminal shake on the rotation picture can be reduced, and the display effect of the terminal picture can be improved.
Fig. 6 is a flowchart illustrating a screen rotation control method according to an embodiment of the present application.
As shown in fig. 6, the screen rotation control method includes:
s201, when the terminal is in a static state, judging whether the terminal generates offset.
According to some embodiments, when the terminal is in a stationary state, the terminal is affected by the surrounding environment, and jitter of a smaller amplitude occurs. The terminal can be judged to rotate by mistake due to the small-amplitude jitter of the terminal, and then the terminal can rotate the display picture. However, at this time, the user does not input a terminal rotation instruction, so that the terminal rotates the display screen of the terminal due to the small amplitude jitter occurring when the terminal is in a static state. Therefore, when the terminal is in a static state, the terminal can judge whether the terminal is deviated or not.
It is easily understood that the terminal can set a preset position of the terminal. When the terminal is in a static state, the terminal can judge whether the position of the terminal is a preset position. And when the terminal judges that the position of the terminal is consistent with the preset position, the terminal does not deviate. When the terminal detects that the position of the terminal is inconsistent with the preset position, the terminal deviates.
And S202, if yes, acquiring the offset of the terminal.
According to some embodiments, when the terminal is in a static state, and the terminal determines that the terminal has an offset, the terminal may obtain the offset of the terminal. The offset may include, for example, an offset angle and an offset direction of the terminal. As shown in fig. 7, for example, the terminal may set a preset position of the terminal to an a position. The terminal can set the position of the terminal display picture as the preset position of the terminal when the terminal display picture is not rotated. When the terminal is in a stationary state, the terminal may determine whether the location of the terminal is the a location. When the terminal judges that the position of the terminal is inconsistent with the position of the preset position A, the terminal is judged to be deviated, and the terminal can acquire the deviation of the terminal. The offset amount of the terminal acquired by the terminal may be, for example, 3 degrees offset in the clockwise direction.
S203, if the offset amount is smaller than the rotation start angle, the first rotation angle is determined to be 0 °.
According to some embodiments, the first rotation angle is a rotation angle of the terminal. The first rotation angle is not specifically referred to a certain fixed rotation angle of the terminal, and the first rotation angle may be, for example, 5 degrees, and the first rotation angle may also be, for example, 3 degrees.
It is easy to understand that when the terminal acquires the offset amount of the terminal, the terminal may determine whether the offset amount of the terminal is smaller than the rotation start angle. And when the terminal judges that the offset of the terminal is smaller than the rotation starting angle, determining the first rotation angle as 0 degree. At this time, the display screen of the terminal is not rotated. For example, the terminal is set to have a rotation start angle of 2 degrees. The offset of the terminal acquired by the terminal may be, for example, 1.5 degrees. When the terminal judges that the offset is 1.5 degrees and is smaller than the rotation starting angle of 2 degrees, the terminal determines the first rotation angle as 0 degree, so that misoperation of the terminal during terminal shaking can be avoided, and the influence of the terminal shaking on a terminal display picture is reduced.
And S204, if the offset is larger than the rotation starting angle, marking a first rotation parameter of the terminal.
According to some embodiments, the first rotation parameter comprises an offset direction and a first rotation angle. The first rotation parameter is not specific to a fixed parameter, and the first rotation angle is not specific to a fixed rotation angle. The first rotation parameter may be, for example, that the offset direction is clockwise and the first rotation angle is 3 degrees, and the first rotation parameter may be, for example, that the offset direction is counterclockwise and the first rotation angle is 5 degrees.
It is easy to understand that when the terminal acquires the offset amount of the terminal, the terminal may determine whether the offset amount of the terminal is smaller than the rotation start angle. When the terminal judges that the offset of the terminal is larger than the rotation starting angle, the terminal starts to rotate according to the first rotation parameter, and at the moment, the terminal marks the first rotation parameter of the terminal, namely the rotation direction of the terminal marking terminal and the rotation parameter of the terminal. For example, the terminal is set to have a rotation start angle of 2 degrees. The offset of the terminal acquired by the terminal may be, for example, 2.5 degrees. When the terminal determines that the offset amount is 2.5 degrees and greater than the rotation start angle by 2 degrees, the first rotation parameter acquired by the terminal may be, for example, that the offset direction is clockwise and the first rotation angle is 90 degrees. The terminal may rotate based on the first rotation parameter, and the terminal may mark the rotation direction of the terminal as a clockwise direction and the rotation angle as a 90 degrees first rotation angle.
Optionally, when the terminal acquires the first rotation parameter of the terminal, the rotation parameter of the terminal display screen may be acquired based on the rotation parameter. The terminal may rotate the display screen based on the acquired rotation parameter of the display screen.

As shown in fig. 7, the screen rotation control method includes:
s301, when the terminal rotates along the first rotation direction, whether the terminal shifts along the second rotation direction is judged.
According to some embodiments, when the terminal is rotated in the first rotation direction, the terminal may determine whether the terminal is shifted in the second rotation direction. The second rotation direction is the reverse direction of the first rotation direction. And when the terminal judges that the terminal does not deviate along the second rotation direction, the terminal continues to rotate according to the first rotation parameter.
It is easy to understand that the first rotation parameter acquired by the terminal may be, for example, that the offset direction is clockwise and the first rotation angle is 90 degrees. When the terminal is rotated in the clockwise direction, the terminal may determine whether the terminal is shifted in the counterclockwise direction. When the terminal determines that the terminal is not shifted in the second rotation direction, the terminal may continue to rotate the terminal in the clockwise direction.
And S302, if yes, acquiring the offset of the terminal in the second rotation direction.
According to some embodiments, when the terminal rotates in the first rotation direction and the terminal determines that the terminal is shifted in the second rotation direction, the terminal may obtain the shift amount of the terminal in the second rotation direction. For example, when the terminal is rotated in a clockwise direction, the terminal may determine whether the terminal is shifted in a counterclockwise direction. When the terminal determines that the terminal is shifted in the counterclockwise direction, the terminal may obtain an offset of the terminal in the counterclockwise direction, which may be, for example, 1.5 degrees.
S303, if the offset is smaller than the rotation start angle, marking a first rotation parameter of the terminal, where the first rotation parameter includes a third rotation direction and a first rotation angle, and the third rotation direction is the first rotation direction.
According to some embodiments, when the terminal acquires the offset amount of the terminal in the second rotation direction, the terminal may determine whether the offset is smaller than the rotation start angle. When the terminal judges that the offset is smaller than the rotation starting angle, the terminal marks a first rotation parameter of the terminal. The first rotation parameter includes a third rotation direction and a first rotation angle, and the third rotation direction is the first rotation direction.
It is easy to understand that when the terminal rotates based on the acquired first rotation parameter and the terminal determines that the terminal deviates in the second rotation direction, the terminal may acquire that the deviation amount of the terminal in the second rotation direction is 1.5 degrees. The first rotation parameter of the terminal may be, for example, that the offset direction is clockwise and the first rotation angle is 90 degrees. The offset direction is the third rotation direction. The rotation start angle set by the terminal may be, for example, 2 degrees. And when the terminal judges that the acquired offset is 1.5 degrees and is less than the rotation starting angle of 2 degrees, marking a first rotation parameter of the terminal by the terminal, wherein the first rotation parameter of the terminal is that the third rotation direction is clockwise and the first rotation angle is 90 degrees.
304, if the offset is greater than the rotation start angle, a first rotation parameter of the terminal is marked, the first rotation parameter includes a third rotation direction and a first rotation angle, and the third rotation direction is a second rotation direction.
According to some embodiments, when the terminal acquires the offset amount of the terminal in the second rotation direction, the terminal may determine whether the offset is smaller than the rotation start angle. When the terminal judges that the offset is larger than the rotation starting angle, the terminal marks a first rotation parameter of the terminal. The first rotation parameter includes a third rotation direction and a first rotation angle, and the third rotation direction is a second rotation direction.
It is easy to understand that when the terminal rotates based on the acquired first rotation parameter and the terminal determines that the terminal deviates in the second rotation direction, the terminal may acquire that the deviation amount of the terminal in the second rotation direction is 2.5 degrees. The first rotation parameter of the terminal may be, for example, that the offset direction is clockwise and the first rotation angle is 90 degrees. The offset direction is the third rotation direction. The rotation start angle set by the terminal may be, for example, 2 degrees. When the terminal judges that the acquired offset is 2.5 degrees and is greater than the rotation starting angle by 2 degrees, the terminal marks a first rotation parameter of the terminal, wherein the first rotation parameter of the terminal is that the third rotation direction is a counterclockwise direction and the first rotation angle is 90 degrees.
According to some embodiments, when the terminal is rotated in the first rotation direction and when the terminal is subjected to an external thrust different from the first rotation direction, the terminal may generate a terminal shake under the external thrust, and the terminal may determine whether the terminal is shifted in the second rotation direction. The second rotation direction is the reverse direction of the first rotation direction. When the terminal judges that the terminal deviates along the second rotating direction, the terminal can acquire the last rotating angle of the terminal rotating along the first rotating direction under the external thrust and acquire the current rotating angle of the terminal rotating along the first rotating direction. When the terminal acquires the last rotation angle and the current rotation angle, the terminal may calculate a first rotation parameter of the terminal through formula (3) based on a preset first weight, a preset second weight, the last rotation angle, and the current rotation angle, where the first rotation parameter includes a third rotation direction and a first rotation angle.
The first rotation angle is the last rotation angle, the first weight and the current rotation angle are preset, and the second weight formula (3)
It will be readily appreciated that when the terminal is subjected to an applied thrust in the positive X-direction, for example, as shown in fig. 9, as the terminal is rotated in the Z-axis instantaneous pin direction, the terminal can determine whether the terminal is deflected in the counterclockwise Z-axis direction. When the terminal judges that the terminal deviates along the counterclockwise direction of the Z axis, the terminal can acquire the rotation angle of the terminal along the clockwise direction of the Z axis at preset time intervals under the action of the external thrust. When the terminal acquires that the last rotation angle is 35 degrees when the terminal rotates, and acquires that the current rotation angle is 37 degrees when the terminal rotates in the first rotation direction. When the terminal acquires the last rotation angle of 35 degrees and the current rotation angle of 37 degrees, the terminal may calculate a first rotation parameter of the terminal based on a preset first weight, a preset second weight, the last rotation angle, and the current rotation angle, where the first rotation parameter may be, for example, that the third rotation direction is a clockwise direction and the first rotation angle is 36 degrees.
S305, determining a second rotation parameter of the display screen of the terminal based on the first rotation parameter.
According to some embodiments, when the terminal acquires the first rotation parameter, the terminal may determine a second rotation parameter of a display screen of the terminal based on the first rotation parameter. The second rotation parameter includes a fourth rotation direction and a second rotation angle, and the fourth rotation direction is a reverse direction of the third rotation direction.
The specific process is as described above, and is not described herein again.
And S306, rotating the display screen by the second rotation angle along a fourth rotation direction, wherein the fourth rotation direction is the reverse direction of the third rotation direction.
According to some embodiments, when the terminal acquires the second rotation parameter of the terminal display screen, the terminal may rotate the terminal screen based on the second rotation parameter. The second rotation parameter includes a fourth rotation direction and a second rotation angle, so the terminal can rotate the display screen by the second rotation angle in the fourth rotation direction. For example, the second rotation parameter acquired by the terminal is the clockwise direction and the second rotation angle is 90 degrees, and the terminal may rotate the display screen by 90 degrees in the clockwise direction.
The embodiment of the application provides a picture rotation control method, when a terminal rotates along a first rotation direction, the terminal can judge whether the terminal deviates along a second rotation direction, if so, the deviation of the terminal in the second rotation direction is obtained, if the deviation is smaller than a rotation starting angle, a first rotation parameter of the terminal is marked, as the terminal rotates along the first rotation direction, terminal jitter can cause the terminal to have the deviation along the second rotation direction, and by calculating the deviation of the terminal in the second rotation direction, the influence of the terminal jitter on the rotation of the terminal along the first rotation direction can be avoided. If the offset is greater than the rotation starting angle, the terminal marks a first rotation parameter of the terminal, the first rotation parameter includes a third rotation direction and a first rotation angle, and the third rotation direction is a second rotation direction. Based on the first rotation parameter, the terminal can determine a second rotation parameter of a display picture of the terminal, and rotate the display picture by a second rotation angle along a fourth rotation direction, so that the calculation accuracy of the first rotation parameter and the second rotation parameter can be improved, the rotation accuracy of the display picture of the terminal is improved under the condition that the terminal shakes, and the display effect of the display picture of the terminal can be improved.
