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, fig. 1 is a flowchart of an image adjusting method according to an embodiment of the present invention. The method is applied to a mobile terminal, the mobile terminal comprises a foldable display screen, one sub-screen of the display screen can be on the same display surface with another sub-screen through a folding line or stacked, as shown in fig. 1, the method comprises the following steps:
and step 101, displaying images on the two sub-screens respectively.
With the rapid development and progress of communication technology, mobile terminals have gradually advanced into and become an indispensable part of people's lives. Currently, it is a trend to use a mobile terminal to take pictures or videos, and after a user takes pictures or obtains pictures or video contents, the user may need to modify the pictures or video contents, such as beauty treatment, zoom treatment, and cropping treatment, due to personal preferences and the like.
Therefore, in this step, when the user needs to adjust the image, the user may unfold the two sub-screens of the mobile terminal, and even if one display screen is unfolded around the other display screen in a flipping manner, the mobile terminal may control the image that needs to be adjusted to be displayed on both the two sub-screens of the mobile terminal.
The image may be a photo to be adjusted, or may also be a video picture to be adjusted.
And 102, detecting the turning angle between the two sub-screens based on the relative positions of the two sub-screens.
In this step, when the two sub-screens of the mobile terminal are unfolded and the images are displayed on both the two sub-screens, the mobile terminal may detect the turning angle between the two sub-screens according to the relative position between the two sub-screens.
The two sub-screens of the mobile terminal are unfolded, and the display surfaces of the two sub-screens can be on the same display surface, or the display surfaces of the two sub-screens are similar to the same display surface. Further, due to the use habit and the viewing habit of the user, the angle between the display surfaces of the two sub-screens can be an acute angle, so that the user can view the sub-screens conveniently.
The turning angle between the two sub-screens is detected by using an angle sensor, a distance sensor or other sensors which can directly or indirectly detect the angle between the two sub-screens.
And 103, determining a target adjustment coefficient corresponding to the image to be adjusted on the target sub-screen in the display screen based on the corresponding relation between the preset turning angle and the adjustment coefficient of the image.
In this step, after the mobile terminal detects the turning angle between the two sub-screens, the mobile terminal may determine, according to a corresponding relationship between a preset turning angle and an adjustment coefficient of an image, which is preset in the mobile terminal, a target adjustment coefficient corresponding to the turning angle and corresponding to an image to be adjusted on a target sub-screen in the display screen.
The target sub-screen in the display screen may be a default sub-screen of the two sub-screens of the display screen, for example, a default left half screen or a default upper half screen, or a target sub-screen determined according to habits or settings of a user, for example, when the user turns over one of the two sub-screens, the other non-rotated sub-screen is used as the target sub-screen, or the rotated sub-screen is directly used as the target sub-screen.
Therefore, when a user needs to adjust the image to be adjusted, one display screen can be turned over to adjust the turning angle between the two sub-screens, so that the target adjustment coefficient of the image to be adjusted is adjusted more accurately and a finer adjustment effect is achieved compared with the method that parameters are adjusted directly through controls such as a dragging bar on the screen.
And 104, adjusting the image to be adjusted by using the target adjustment coefficient.
In this step, after the mobile terminal determines the target adjustment coefficient according to the turning angle between the two sub-screens, the mobile terminal may use the target adjustment coefficient to adjust the image to be adjusted on the target sub-screen of the two sub-screens of the display screen.
In the embodiment of the present invention, the mobile terminal may have any two foldable sub-screens, and one display screen of the two sub-screens may be turned over to be on the same display surface as the other display screen or to be stacked on the other display screen, for example: a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a laptop Computer (laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
According to the image adjusting method provided by the embodiment of the invention, images are respectively displayed on the two sub-screens; detecting the turning angle between the two sub-screens based on the relative positions of the two sub-screens; determining a target adjustment coefficient corresponding to an image to be adjusted on a target sub-screen in the display screen based on a corresponding relation between a preset turning angle and an adjustment coefficient of the image; and adjusting the image to be adjusted by using the target adjustment coefficient. Therefore, images can be displayed on the two sub-screens of the mobile terminal, the images to be adjusted on the target sub-screen are adjusted, the adjusted images can be compared with the original images when the images are adjusted by a user, the adjustment coefficient can be changed by rotating one of the display screens in real time by the user, the purpose of accurate adjustment is achieved, operation is simple, and user experience is improved.
Referring to fig. 2, fig. 2 is a flowchart of an image adjustment method according to another embodiment of the present invention. The method is applied to a mobile terminal, the mobile terminal comprises a foldable display screen, one sub-screen of the display screen can be on the same display surface with another sub-screen through a folding line or stacked, as shown in fig. 2, the method comprises the following steps:
and step 201, displaying images on the two sub-screens respectively.

Therefore, a user can rotate one display screen of the two sub-screens in real time to change the turning angle between the two sub-screens, so that the purpose of changing the adjustment coefficient is achieved. For example, when the user needs to perform the facial beautification processing on the picture to be adjusted, the user can rotate and adjust one display screen in real time, for example, when the display screen performs forward rotation, the facial beautification degree can be improved, and when the display screen performs reverse rotation, the facial beautification degree can be reduced, or, when the user needs to perform the amplification or the contraction of the picture to be adjusted, the user can rotate and adjust one display screen in real time, for example, when the display screen performs forward rotation, the image can be amplified, and when the display screen performs reverse rotation, the image can be reduced.
And 203, determining that the non-rotated sub-screen in the two sub-screens is the target sub-screen based on the rotation information.
In this step, the mobile terminal may obtain rotation information of the two sub-screens, so that a relatively non-rotated sub-screen of the two sub-screens is used as a target sub-screen on which an image displayed on the sub-screen needs to be adjusted.
And 204, detecting the turning angle between the two sub-screens based on the relative positions of the two sub-screens.

Optionally, step 205 includes:
firstly, determining a target scaling factor of an image to be adjusted on a target sub-screen in the sub-screen based on the corresponding relation between the target adjustment coefficient and the scaling factor.
In this step, after the user needs to enlarge or reduce the image to be adjusted, and the mobile terminal determines the target adjustment coefficient according to the turning angles of the two sub-screens, the mobile terminal may determine the target scaling factor that needs to adjust the image to be adjusted on the target sub-screen of the two sub-screens according to a preset corresponding relationship between the target adjustment coefficient and the scaling factor.
Secondly, zooming the image to be adjusted on the target sub-screen according to the target zooming multiple, and obtaining a zoomed image.
