When the front-end photographing is not carried out, different applications can be respectively displayed through the first display screen and the second display screen so as to be provided for users who do not use the mobile terminal, and the display and use functions of the mobile terminal are enriched.
According to the photographing method provided by the embodiment of the invention, the two display screens are provided and can be rotatably connected, light supplement is realized through one display screen, the display screen for light supplement can rotate, so that the light supplement angle and the light supplement effect can be adjusted, a front light supplement lamp does not need to be additionally arranged, the appearance of a mobile phone is not influenced, photographing preview is realized through the other display screen, the user experience is improved, the display and use functions of the mobile terminal are enriched due to the double-screen arrangement, and the technological sense of the mobile terminal is increased.
Specifically, referring to fig. 1a and 1B, the display screen a and the display screen B are rotatably connected by a rotating structure 22; a motor 23 is arranged between the display screen A and the display screen B and used for driving the display screen A or the display screen B to rotate; an angle sensor 24 is arranged between the display screen A and the display screen B and used for detecting the angle formed by the plane of the display screen A and the plane of the display screen B.
Optionally, referring to fig. 3, the photographing method further includes:
step 205, controlling the first display screen to rotate, so that a preset angle is formed between the plane where the first display screen is located and the plane where the second display screen is located.
Here, through the rotation of the first display screen (like display screen B) that control is used for the light filling to make the plane of first display screen place and the plane of the second display screen (like display screen A) place that is used for the preview become preset angle, make the light of leading light filling can illuminate the people or the thing that will shoot better, reach better light filling effect, promoted user's the experience of shooing.
The predetermined angle may be, but is not limited to, 180 degrees. The preset angle may be a default value of the system or a value set by a user.
The assumption is that the preset angle is 180 degrees, and first display screen is display screen B, and the second display screen is display screen A, and when the user utilized leading camera on the display screen A to autodyne, because display screen B becomes 180 degrees with display screen A, the user can be illuminated better to the light that consequently display screen B carries out the light filling, reaches better light filling effect.
Certainly, the user can also rotate according to the first display screen of the manual control of own demand to adjust light filling angle and light filling effect.
In step 205, an angle formed by a plane of the first display screen (e.g., display screen B) and a plane of the second display screen (e.g., display screen B) is detected by the angle sensor 24, and the motor 23 drives the first display screen (display screen B) to rotate, so that the plane of the first display screen and the plane of the second display screen (display screen a) form a preset angle.
Step 205 can be executed after step 202 when the instruction for triggering photographing is detected, so that a better light supplementing effect can be achieved during photographing, and the photographing experience of a user is improved. Step 205 can also be executed before step 202, so that a better light compensation effect can be achieved during shooting preview, and the shooting experience of the user is further improved.
And step 206, controlling the target front-facing camera to take pictures when detecting the command of triggering the picture taking.
Here, because the first display screen is utilized to realize a better light compensation effect, when an instruction for triggering photographing is detected, the target front camera is controlled to photograph, and a picture with the better light compensation effect is obtained.
The process of taking a picture by the front camera of the specific target can be implemented by any known method, which is not limited in the present invention.
As can be seen from the foregoing, in order to obtain a better light compensation effect, the first display screen for light compensation needs to be controlled to rotate, but if the user holds the first display screen, the first display screen cannot be driven to rotate. To avoid this problem, as shown in fig. 4, before step 205, the method further includes:
step 207, detecting the held display screen.
And 208, prompting a user to hold the second display screen when the held display screen is the first display screen.
Here, when detecting that the held display screen is the first display screen for supplementing light, the user is prompted to hold the second display screen, and when the user holds the second display screen, the purpose of controlling the first display screen to rotate can be achieved.
The step 205 includes:
step 2051, when the held display screen is the second display screen, controlling the first display screen to rotate so that a plane where the first display screen is located and a plane where the second display screen is located form a preset angle.
Here, when the display screen that is held is the second display screen that is used for the preview of shooing, can control first display screen rotation smoothly to make first display screen place plane and second display screen place plane become the angle of predetermineeing, thereby reach better light compensation effect.
For example, as shown in fig. 1a, a front camera 21 is provided on the display screen a. And determining the front camera on the display screen A as a target front camera, supplementing light by using the display screen B, and performing photographing preview by using the display screen A. When the user holds the display screen B, the user is prompted to hold the display screen A, and when the user holds the display screen A, the display screen B is controlled to rotate, so that a plane where the display screen B is located and a plane where the display screen A is located form a preset angle, and a better light compensation effect is achieved.
When the user is prompted to hold the second display screen, whether the user selects to hold the second display screen can be detected, if the user selects to hold the second display screen, the first display screen can be controlled to rotate through the step 205, and if the user selects not to hold the second display screen but to continue to hold the first display screen, the step 205 can be not executed, the first display screen is not controlled to rotate, and the step 206 is directly executed to take a picture.
Because the mobile terminal has two display screens, it is random that the user holds a certain display screen, if the user holds the display screen of light filling, then need switch the display screen that holds, brought the inconvenience for the user. In order to avoid this problem, optionally, a front camera is disposed on each of the two display screens; in step 201, before determining and turning on the target front camera, the method further includes:
step 209, detecting the held display screen;
in step 201, the step of determining the target front camera includes:
in step 2011, the front camera on the held display screen is determined as the target front camera.
Here, the front camera on the display screen to be held is determined as the target front camera, the second display screen provided with the target front camera and used for previewing is the display screen to be held by the user, and the first display screen not provided with the target front camera and used for light supplement is not the display screen to be held by the user, so that the second display screen is guaranteed to be held by the user, the purpose of controlling the rotation of the first display screen is achieved, the display screen to be held by the user does not need to be switched, and user experience is improved.
For example, as shown in fig. 1B, a front camera 21 is provided on each of the display screen a and the display screen B. When a user holds the display screen A, the front camera on the display screen A is determined as the target front camera, light supplement is performed by using the display screen B, photographing preview is performed by using the display screen A, and the display screen B is controlled to rotate, so that a plane where the display screen B is located and a plane where the display screen A is located form a preset angle, and a better light supplement effect is achieved.
When a user holds the display screen B, the front camera on the display screen B is determined as the target front camera, light supplement is performed by using the display screen A, photographing preview is performed by using the display screen B, and the display screen A is controlled to rotate so that the plane where the display screen A is located and the plane where the display screen B is located form a preset angle to achieve a better light supplement effect.
As an alternative implementation manner, in step 207 or step 209, the step of detecting the held display screen includes:

Here, as shown in fig. 1a and 1B, either display a or display B may be used as the test display. Wherein, if what the user held is the test display screen, then control the test display screen and carry out rotatory operation and will receive the hindrance, the test display screen can't rotate, if what the user held is not the test display screen, then the test display screen can rotate. Therefore, the test display screen is controlled to rotate, whether the test display screen can rotate or not can be determined, and the held display screen can be effectively detected.
And step 211, if it is detected that the test display screen cannot rotate, determining the test display screen as the held display screen, otherwise, determining another display screen except the test display screen as the held display screen.
Here, if it is detected that the test display screen cannot rotate, which indicates that the user holds the test display screen, and the operation of controlling the test display screen to rotate is hindered, the test display screen is determined as the held display screen. And if the test display screen is detected to be capable of rotating, which indicates that the test display screen is not held by the user, determining the other display screen as the held display screen.
For example, the display screen a is used as a test display screen, the display screen a is controlled to rotate, if it is detected that the display screen a cannot rotate, the display screen a is determined as a held display screen, otherwise, the display screen B is determined as a held display screen.
As another alternative implementation manner, in step 207 or step 209, the step of detecting the held display screen includes:
and step 212, detecting touch operations of touch edge areas of the two display screens.
Here, when the user holds the display screen, at least two fingers are used to hold the display screen at the edge of the display screen, so that a touch operation is generated in the touch edge area of the display screen. In this step, by detecting the touch operations of the touch edge areas of the two display screens, the display screen which corresponds to the touch operations and is likely to be held can be detected.
In step 213, if a touch operation in a touch edge area of the display screen is detected, it is determined whether the number of touch points of the touch operation is greater than or equal to a preset threshold.
Here, if a touch operation is detected in the touch edge area of one display screen, the touch operation may be an erroneous touch, or may be generated because the display screen corresponding to the touch operation is held. By further judging whether the number of the touch points of the touch operation is larger than or equal to a preset threshold value, whether the touch operation is generated because the display screen is held can be effectively determined, namely whether the display screen corresponding to the touch operation is the held display screen is determined.
The preset threshold may be set according to a requirement, and may be 3 or 4, for example.
And 214, if yes, determining the display screen corresponding to the touch operation as the held display screen.
Here, if the number of touch points of the touch operation is greater than or equal to the preset threshold, it may be determined whether the touch operation is generated because the display screen is held, and the display screen corresponding to the touch operation is determined as the held display screen.
Further, if the number of the touch points of the touch operation is greater than or equal to a preset threshold, it may be determined whether both opposite edges of the touch edge area receive the touch operation, and if both opposite edges of the touch edge area receive the touch operation, the display screen corresponding to the touch operation is determined as the held display screen.
Optionally, the step 202 includes:
acquiring brightness information of a current environment; and controlling the first display screen to display a bright color layer according to the brightness information of the current environment. The bright color layer has brighter color and higher brightness. The brightness may be the highest brightness or may be brightness of other levels, which may be determined according to actual needs. The color of the bright color layer may be white, yellow, light blue, etc.
At the moment, the first display screen is controlled to display the bright color layer by combining the brightness information of the current environment, and the light supplementing effect is improved.
Specifically, the backlight brightness to be supplemented may be calculated according to a difference between the set ambient brightness and the current ambient brightness, and the bright color layer may be displayed on the first display screen by using the backlight with the corresponding brightness according to the backlight brightness to be supplemented. In order to ensure that the color of the supplemental backlight does not affect the photographing environment, a pure white picture or a pure gray picture can be adopted.
