An android operating system is taken as an example, and a software environment applied to the image display method provided by the embodiment of the invention is introduced.

Fig. 1 is a schematic diagram of an architecture of an android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the image display method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the image display method may operate based on the android operating system shown in fig. 1. Namely, the processor or the mobile terminal can realize the image display method provided by the embodiment of the invention by running the software program in the android operating system.

The mobile terminal in the embodiment of the present invention may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted mobile terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a Personal Digital Assistant (PDA), and the like, and the embodiment of the present invention is not particularly limited.

The execution subject of the image display method provided by the embodiment of the present invention may be the mobile terminal, or may also be a functional module and/or a functional entity capable of implementing the image display method in the mobile terminal, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a mobile terminal as an example to exemplarily explain an image display method provided by the embodiment of the present invention.

As shown in fig. 2, an embodiment of the invention provides an image display method. The method may be applied to a mobile terminal including a first screen and a second screen, and the method may include steps 101 and 102 described below.

Step 101, under the condition that the first screen displays the first image at the first display angle and the second screen displays the second image at the display angle corresponding to the first display angle, the mobile terminal detects the rotation angle of the first screen and the rotation angle of the second screen.

The first image and the second image may be two parts of a three-dimensional image.

In the embodiment of the present invention, the first display angle and the display angle corresponding to the first display angle are both described with reference to a spatial rectangular coordinate system established with respect to the mobile terminal. Specifically, the spatial rectangular coordinate system may include a first coordinate axis, a second coordinate axis, and a third coordinate axis. For example, the straight line of the first coordinate axis may be a central axis of the mobile terminal, the straight line of the second coordinate axis may be a target axis of the mobile terminal, and the third coordinate axis may be perpendicular to the first coordinate axis and the second coordinate axis. The central axis of the mobile terminal is an axis where a connecting line of the first screen and the second screen is located, and the target axis of the mobile terminal is a straight line parallel to a straight line where the bottom of the first screen or the bottom of the second screen is located.

In an embodiment of the present invention, the first display angle and the display angle corresponding to the first display angle are two display angles in the spatial rectangular coordinate system. The first display angle may be a display angle of a portion of the three-dimensional image in the spatial rectangular coordinate system when the three-dimensional image is not rotated, that is, a display angle of the first image in the first screen; the display angle corresponding to the first display angle may be a display angle of another portion of the three-dimensional image in the spatial rectangular coordinate system when the three-dimensional image is not rotated, that is, a display angle of the second image in the second screen.

For example, as shown in fig. 3, a straight line of a first coordinate axis may be a central axis 03 of the mobile terminal, a straight line of a second coordinate axis may be a straight line 04 of a bottom of the mobile terminal, and a third coordinate axis is perpendicular to the first coordinate axis and the second coordinate axis (not shown in fig. 3). Under the condition that an included angle between a first screen and a second screen of the mobile terminal is a preset angle, if a user wants to view a three-dimensional image, the user can trigger the mobile terminal to display a first image 01 at a first display angle on the first screen through touch input, voice input, gesture input or the like, and display a second image 02 at a display angle corresponding to the first display angle on the second screen. The first display angle may be a display angle of a part of the three-dimensional image on the first screen when the three-dimensional image is not rotated; the display angle corresponding to the first display angle may be a display angle of another portion of the three-dimensional image on the second screen when the three-dimensional image is not rotated.

Optionally, in the embodiment of the present invention, the first screen and the second screen of the mobile terminal may be two independent screens, and the first screen and the second screen may be connected by a shaft or a hinge, etc.; alternatively, the screen of the mobile terminal may be a flexible screen, and the flexible screen may be folded into the first screen and the second screen.

Optionally, in the embodiment of the present invention, the rotation angle of the first screen and the rotation angle of the second screen may include the following two possible implementation manners:

a first possible implementation manner is that the rotation angle of one screen may be an angle of rotation of one screen around the central axis of the mobile terminal, that is, the rotation angle of the first screen is an angle of rotation of the first screen around the central axis of the mobile terminal, and the rotation angle of the second screen is an angle of rotation of the second screen around the central axis of the mobile terminal. The central axis of the mobile terminal is the axis where the connecting line of the first screen and the second screen is located.

The second possible implementation manner is that the mobile terminal can rotate around the target axis to drive the first screen and the second screen to rotate, and the rotation angle of the first screen and the rotation angle of the second screen are both rotation angles of the mobile terminal around the target axis. The target axis is a straight line parallel to a straight line where the bottom of the first screen or the second screen is located.

Further, in the embodiment of the present invention, the mobile terminal may acquire the rotation angle of the first screen and the rotation angle of the second screen through a sensor disposed in the mobile terminal. For example, the sensor may be a gravity sensor or a gyro sensor, etc. Reference may be made to the prior art, and details of embodiments of the present invention are not repeated.

And 102, under the condition that the rotation angle of the first screen meets a first preset condition and the rotation angle of the second screen meets a second preset condition, the mobile terminal displays a three-dimensional image on a target screen at a target display angle.

The target screen may be at least one of the first screen and the second screen. The target display angle may be determined by the first display angle, the rotation angle of the first screen, and the rotation angle of the second screen.

It should be noted that, in the embodiment of the present invention, the target display angle is a display angle corresponding to the three-dimensional image after being rotated.

Alternatively, in the case where the rotation angle of the first screen and the rotation angle of the second screen are the rotation angles in the first possible implementation manner in step 101, the first preset condition and the second preset condition may be any one of the following (1) to (4); in the case where the rotation angle of the first screen and the rotation angle of the second screen are the second possible implementation manner in step 101 described above, the first preset condition and the second preset condition may be (5) described below.

(1) The first preset condition may be that the rotation angle of the first screen is greater than a first angle threshold, and the second preset condition may be that the rotation angle of the second screen is less than or equal to the first angle threshold.

Illustratively, assume that the first angle threshold is 0 °. If the rotation angle of the first screen around the central axis of the mobile terminal is 90 degrees and the rotation angle of the second screen around the central axis of the mobile terminal is 0 degrees, the mobile terminal can determine that the rotation angle of the first screen is greater than a first angle threshold value, namely the rotation of the first screen meets a first preset condition; and determining that the rotation angle of the second screen is equal to the first angle threshold, namely that the rotation of the second screen meets a second preset condition.

(2) The first preset condition may be that the rotation angle of the first screen is less than or equal to a first angle threshold, and the second preset condition may be that the rotation angle of the second screen is greater than the first angle threshold.

Illustratively, assume that the first angle threshold is 0 °. If the rotation angle of the first screen around the central axis of the mobile terminal is 0 ° and the rotation angle of the second screen around the central axis of the mobile terminal is 90 °, the mobile terminal may determine that the rotation angle of the first screen is equal to the first angle threshold, that is, the rotation of the first screen satisfies a first preset condition; and determining that the rotation angle of the second screen is greater than the first angle threshold, namely that the rotation of the second screen meets a second preset condition.

(3) The first preset condition may be that the rotation angle of the first screen is greater than a first angle threshold, and the second preset condition may be that the rotation angle of the second screen is greater than the first angle threshold.

Illustratively, assume that the first angle threshold is 0 °. If the rotation angle of the first screen around the central axis of the mobile terminal is 45 degrees and the rotation angle of the second screen around the central axis of the mobile terminal is 45 degrees, the mobile terminal can determine that the rotation angle of the first screen is greater than a first angle threshold value, namely the rotation of the first screen meets a first preset condition; and determining that the rotation angle of the second screen is greater than the first angle threshold, namely that the rotation of the second screen meets a second preset condition.

(4) The first preset condition may be that the rotation angle of the first screen is less than or equal to a first angle threshold, and the second preset condition may be that the rotation angle of the second screen is less than or equal to the first angle threshold.

Illustratively, the first angle threshold may be 10 °, 20 °, 30 °, or the like.

Illustratively, assume that the first angle threshold is 20 °. If the rotation angle of the first screen around the central axis of the mobile terminal is 10 degrees and the rotation angle of the second screen around the central axis of the mobile terminal is 5 degrees, the mobile terminal can determine that the rotation angle of the first screen is smaller than a first angle threshold value, namely the rotation of the first screen meets a first preset condition; and determining that the rotation angle of the second screen is smaller than the first angle threshold, namely that the rotation of the second screen meets a second preset condition.

(5) The first preset condition is that the rotation angle of the first screen is larger than a second angle threshold, and the second preset condition is that the rotation angle of the second screen is larger than the second angle threshold.

Illustratively, assume that the second angle threshold is 0 °. If the rotation angle of the first screen around the target axis is 30 ° and the rotation angle of the second screen around the target axis is 30 °, the mobile terminal may determine that the rotation angle of the first screen is greater than a second angle threshold, that is, the rotation of the first screen satisfies a first preset condition, and determine that the rotation angle of the second screen is greater than the second angle threshold, that is, the rotation of the second screen satisfies a second preset condition.

It should be noted that, in the embodiment of the present invention, the second angle threshold may be equal to the first angle threshold, or may not be equal to the first angle threshold. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

It can be understood that, since the mobile terminal can set the judgment condition according to the angle of the first screen and the second screen rotating around the central axis of the mobile terminal, and also can set the judgment condition according to the angle of the first screen and the second screen rotating around the target axis, the flexibility and diversity of the mobile terminal setting judgment condition are improved.

The embodiment of the invention provides an image display method, and a mobile terminal can simultaneously rotate and display a three-dimensional image on a first screen or rotate and display a three-dimensional image on a second screen or rotate and display a three-dimensional image on the first screen and the second screen according to the rotation angle of the first screen and the rotation angle of the second screen, so that the flexibility of the image display method provided by the embodiment of the invention is higher.

Optionally, in an embodiment of the present invention, when the first preset condition and the second preset condition are any one of the above (1) to (4), the step 102 may be specifically implemented by any one of the following steps 102A to 102D. Alternatively, when the first preset condition and the second preset condition are (5) above, the step 102 may be specifically realized by a step 102E described below.

It should be noted that, in the following steps 102A to 102D, and 102E, a straight line where a first coordinate axis is located is used as a central axis of the mobile terminal, a straight line where a second coordinate axis is located is used as a target axis of the mobile terminal, and the third coordinate axis is perpendicular to the first coordinate axis and the second coordinate axis, which is taken as an example for exemplary illustration and does not limit the embodiments of the present invention at all. It can be understood that, in actual implementation, the first coordinate axis, the second coordinate axis, and the third coordinate axis may also be other possible coordinate axes, which may specifically be determined according to actual usage requirements.

And 102A, under the condition that the rotation angle of the first screen is larger than a first angle threshold value and the rotation angle of the second screen is smaller than or equal to the first angle threshold value, the mobile terminal displays the three-dimensional image on the second screen at a second display angle.

The second display angle may be a display angle corresponding to the three-dimensional image after rotating around the first coordinate axis in the spatial rectangular coordinate system.

Optionally, in this embodiment of the present invention, an absolute value of a difference between the second display angle and the first display angle may be proportional to the rotation angle of the first screen. For example, the ratio between the absolute value of the difference between the second display angle and the first display angle and the rotation angle of the first screen may be 2:1, 3:1, 4:1, or 6:1, etc.

The following is exemplified by the first angle threshold being 0 °, and the ratio between the absolute value of the difference between the second display angle and the first display angle and the rotation angle of the first screen being 2: 1:

for example, as shown in (a) of fig. 4, if the first screen is rotated clockwise by 30 ° about the central axis 03 of the mobile terminal and the second screen is rotated by 0 ° about the central axis 03 of the mobile terminal, the mobile terminal may determine that the rotation angle of the first screen is greater than a first angle threshold and the rotation angle of the second screen is equal to the first angle threshold, that is, it is determined that the rotation of the first screen satisfies a first preset condition and the rotation of the second screen satisfies a second preset condition. In this manner, the mobile terminal may rotate the three-dimensional image shown in fig. 3 clockwise about the first coordinate axis by 60 °, and display the three-dimensional image on the second screen at the second display angle.

For example, as shown in (b) of fig. 4, if the first screen is rotated counterclockwise by 30 ° about the central axis 03 of the mobile terminal and the second screen is rotated by 0 ° about the central axis 03 of the mobile terminal, the mobile terminal may determine that the rotation angle of the first screen is greater than a first angle threshold, and the rotation angle of the second screen is equal to the first angle threshold, that is, it is determined that the rotation of the first screen satisfies a first preset condition and the rotation of the second screen satisfies a second preset condition. As such, the mobile terminal may rotate the three-dimensional image shown in fig. 3 counterclockwise by 60 ° about the first coordinate axis and display the three-dimensional image at the second display angle on the second screen.

According to the image display method provided by the embodiment of the invention, the rotated three-dimensional image can be displayed on the second screen under the condition that the first screen rotates around the central axis of the mobile terminal and the second screen does not rotate around the central axis of the mobile terminal, so that a user can check the three-dimensional image and the flexibility of image display is improved.

And 102B, under the condition that the rotation angle of the first screen is smaller than or equal to the first angle threshold value and the rotation angle of the second screen is larger than the first angle threshold value, the mobile terminal displays the three-dimensional image on the first screen at a third display angle.

The third display angle may be a display angle corresponding to the three-dimensional image after rotating around the second coordinate axis in the spatial rectangular coordinate system.

Optionally, in this embodiment of the present invention, an absolute value of a difference between the third display angle and the first display angle may be proportional to the rotation angle of the second screen. For example, the ratio between the absolute value of the difference between the third display angle and the first display angle and the rotation angle of the second screen may be 2:1, 3:1, 4:1, or 6:1, etc.

The following is exemplified by the first angle threshold being 0 °, and the ratio between the absolute value of the difference between the third display angle and the first display angle and the rotation angle of the second screen being 3: 1:

for example, as shown in (a) of fig. 5, if the first screen is rotated by 0 ° around the central axis 03 of the mobile terminal and the second screen is rotated by 30 ° counterclockwise around the central axis 03 of the mobile terminal, the mobile terminal may determine that the rotation angle of the first screen is equal to a first angle threshold and the rotation angle of the second screen is greater than the first angle threshold, that is, it is determined that the rotation of the first screen satisfies a first preset condition and the rotation of the second screen satisfies a second preset condition. As such, the mobile terminal may rotate the three-dimensional image shown in fig. 3 counterclockwise by 90 ° about the second coordinate axis and display the three-dimensional image at the third display angle on the first screen.

For example, as shown in (b) of fig. 5, if the first screen is rotated by 0 ° about the central axis 03 of the mobile terminal and the second screen is rotated by 30 ° clockwise about the central axis 03 of the mobile terminal, the mobile terminal may determine that the rotation angle of the first screen is equal to a first angle threshold and the rotation angle of the second screen is greater than the first angle threshold, that is, it is determined that the rotation of the first screen satisfies a first preset condition and the rotation of the second screen satisfies a second preset condition. In this manner, the mobile terminal may rotate the three-dimensional image shown in fig. 3 clockwise by 90 ° about the second coordinate axis and display the three-dimensional image at the third display angle on the first screen.

According to the image display method provided by the embodiment of the invention, the rotated three-dimensional image can be displayed on the first screen under the condition that the second screen rotates around the central axis of the mobile terminal and the first screen does not rotate around the central axis of the mobile terminal, so that a user can check the three-dimensional image and the flexibility of image display is improved.

And 102C, under the condition that the rotation angle of the first screen is larger than the first angle threshold value and the rotation angle of the second screen is larger than the first angle threshold value, the mobile terminal displays one part of the three-dimensional image at a fourth display angle on the first screen and displays the other part of the three-dimensional image at a fifth display angle on the second screen.

And the fifth display angle is a display angle corresponding to the fourth display angle. The fourth display angle and the fifth display angle may be display angles corresponding to the three-dimensional image after rotating around the third coordinate axis in the spatial rectangular coordinate system.

Optionally, in this embodiment of the present invention, an absolute value of a difference between the fourth display angle and the first display angle may be proportional to a sum of a rotation angle of the first screen and a rotation angle of the second screen; an absolute value of a difference value between the fifth display angle and the first display angle may be proportional to a sum of the rotation angle of the first screen and the rotation angle of the second screen. For example, the ratio between the absolute value of the difference between the fourth display angle and the first display angle and the sum of the rotation angle of the first screen and the rotation angle of the second screen may be 2:1, 3:1, 4:1, or 6:1, etc.; the ratio between the absolute value of the difference between the fifth display angle and the first display angle and the sum of the rotation angle of the first screen and the rotation angle of the second screen may be 2:1, 3:1, 4:1, 6:1, or the like.

The following description will be exemplarily made by taking an example in which the first angle threshold is 0 °, the ratio between the absolute value of the difference between the fourth display angle and the first display angle and the sum of the rotation angle of the first screen and the rotation angle of the second screen is 2:1, and the ratio between the absolute value of the difference between the fifth display angle and the first display angle and the sum of the rotation angle of the first screen and the rotation angle of the second screen is 2: 1:

for example, as shown in (a) of fig. 6, if the first screen is rotated clockwise by 30 ° about the central axis 03 of the mobile terminal and the second screen is rotated counterclockwise by 30 ° about the central axis 03 of the mobile terminal, the mobile terminal may determine that the rotation angle of the first screen is greater than a first angle threshold and the rotation angle of the second screen is greater than the first angle threshold, that is, it is determined that the rotation of the first screen satisfies a first preset condition and the rotation of the second screen satisfies a second preset condition. In this manner, the mobile terminal may rotate the three-dimensional image shown in fig. 3 clockwise about the third coordinate axis by 120 °, display a portion of the three-dimensional image at a fourth display angle on the first screen, and display another portion of the three-dimensional image at a fifth display angle on the second screen.

For example, as shown in (b) of fig. 6, if the first screen is rotated counterclockwise by 30 ° about the central axis 03 of the mobile terminal and the second screen is rotated clockwise by 30 ° about the central axis 03 of the mobile terminal, the mobile terminal may determine that the rotation angle of the first screen is greater than a first angle threshold and the rotation angle of the second screen is greater than the first angle threshold, that is, it is determined that the rotation of the first screen satisfies a first preset condition and the rotation of the second screen satisfies a second preset condition. In this manner, the mobile terminal may rotate the three-dimensional image shown in fig. 3 counterclockwise about the third coordinate axis by 120 °, display a portion of the three-dimensional image at a fourth display angle on the first screen, and display another portion of the three-dimensional image at a fifth display angle on the second screen.

According to the image display method provided by the embodiment of the invention, the rotated three-dimensional images can be displayed on the first screen and the second screen under the condition that the first screen and the second screen are rotated around the central axis of the mobile terminal, so that the flexibility of image display is improved.

For example, if the first screen rotates 10 ° counterclockwise around the central axis of the mobile terminal and the second screen rotates 10 ° clockwise around the central axis of the mobile terminal, the mobile terminal may determine that the rotation angle of the first screen is smaller than the first angle threshold and the rotation angle of the second screen is smaller than the first angle threshold, that is, it is determined that the rotation of the first screen satisfies the first preset condition and the rotation of the second screen satisfies the second preset condition.

And the seventh display angle is a display angle corresponding to the sixth display angle. The sixth display angle and the seventh display angle may be display angles corresponding to the three-dimensional image after rotating around one coordinate axis in the spatial rectangular coordinate system.

Optionally, in this embodiment of the present invention, an absolute value of a difference between the sixth display angle and the first display angle is directly proportional to an angle of rotation of the mobile terminal around the target axis; an absolute value of a difference between the seventh display angle and the first display angle is proportional to an angle by which the mobile terminal is rotated about the target axis.

For example, the ratio between the absolute value of the difference between the sixth display angle and the first display angle and the sum of the rotation angle of the first screen and the rotation angle of the second screen may be 2:1, 3:1, 4:1, or 6:1, etc.; the ratio between the absolute value of the difference between the seventh display angle and the first display angle and the sum of the rotation angle of the first screen and the rotation angle of the second screen may be 2:1, 3:1, 4:1, 6:1, or the like.
