As shown in FIG. 1, a dual-screen terminal shown in an embodiment of the present invention includes a first screen and a second screen, and the long sides of the first screen and the second screen are rotatably connected. The first screen and An angle sensor and a motor are installed at the connection of the second screen; wherein, the angle sensor is configured to detect an angle between the first screen and the second screen, and the processor may obtain the first screen through the angle sensor. An angle between a screen and the second screen; the motor is configured to adjust an angle between the first screen and the second screen under the control of the processor. Based on the structure of the dual-screen terminal, the following embodiments of the present invention are proposed.

Example one

FIG. 2 is a schematic flowchart of a self-timer fill light method provided in Embodiment 1 of the present invention. The method is executed by a dual-screen terminal shown in FIG. 1. As shown in FIG. 2, the self-timer fill light method provided in this embodiment may include the following steps:

In step S201, when it is detected that the user performs a self-timer operation through the first screen of the dual-screen terminal, brightness information of the environment around the first screen is acquired.

In this embodiment, the processor in the dual-screen terminal determines whether the user has performed a selfie operation through the first screen of the dual-screen terminal by detecting whether a first-screen self-timer instruction input by the user is received; or, By detecting whether the application program corresponding to the self-portrait camera on the first screen is in a running state, it is determined whether the user has performed a self-portrait operation through the first screen of the dual-screen terminal.

In this embodiment, a light sensor is provided around the self-photographing camera head of the first screen, and the processor of the dual-screen terminal controls the light sensor to detect the photo sensor when detecting that the user performs a self-timer operation through the first screen. The brightness information of the surroundings of the first screen is described, and the brightness information detected by the light sensor is read.

In step S202, it is determined whether the brightness information is less than a preset brightness threshold; when the brightness information is less than the preset brightness threshold, the process proceeds to step S203.

In this embodiment, when the brightness information is less than the preset brightness threshold, it indicates that the ambient light of the self-timer is poor at this time, and the supplementary light effect needs to be adjusted. At this time, the process proceeds to step S203; otherwise, no processing is performed.

In step S203, the angle and / or brightness of the second screen of the dual-screen terminal is adjusted until the brightness information of the environment around the first screen reaches the best light-filling effect.

The best lighting effect is that the brightness information around the first screen reaches the preset brightness threshold, or the brightness information around the first screen does not reach the preset brightness threshold but reaches an upper limit .

Step S202 specifically includes:

Determining whether the angle of the second screen with respect to the first screen is equal to 90 degrees;

If the angle is not equal to 90 degrees, adjusting the angle of the second screen to 90 degrees according to a first preset step, and monitoring the brightness information of the surrounding environment of the first screen in real time during the adjustment process;

If during the adjustment, the brightness information of the surrounding environment of the first screen reaches the preset brightness threshold, stop adjusting the angle of the second screen;

If the angle is adjusted to 90 degrees, and the brightness information of the environment around the first screen still does not reach the preset brightness threshold, the brightness of the second screen is increased according to a second preset step until the first The brightness information of the environment around a screen reaches the preset brightness threshold.

In this embodiment, if the angle is not equal to 90 degrees, adjusting the angle of the second screen to 90 degrees according to a first preset step specifically includes:

If the angle is greater than 90 degrees, reducing the angle of the second screen to 90 degrees according to the first preset step;

If the angle is less than 90 degrees, the angle of the second screen is increased to 90 degrees according to the first preset step.

In this embodiment, during the process of adjusting the angle of the second screen, if it is detected that the brightness information of the surrounding environment of the first screen reaches the preset threshold, it means that the best light supplement effect is achieved. Stop adjusting the angle of the second screen, keep the angle and brightness of the second screen unchanged, and take a picture.

After determining whether the angle of the second screen with respect to the first screen is equal to 90 degrees, the method further includes:

If the angle is equal to 90 degrees, the brightness of the second screen is directly increased according to a second preset step until the brightness information of the environment around the first screen reaches the preset brightness threshold.

In this embodiment, when the brightness of the second screen is constant, when the angle of the second screen with respect to the first screen reaches 90 degrees, the brightness information of the environment around the first screen will be optimal. At this time, if the angle of the second screen is adjusted again, it will affect the fill light effect, so at this time, the fill light effect is directly enhanced by adjusting the brightness value of the second screen.

In this embodiment, when the processor of the dual-screen terminal increases the brightness of the second screen according to a second step, the processor of the dual-screen terminal will control the light sensor to monitor the light sensor in real time. The brightness information around the first screen, when the brightness information around the first screen reaches the preset threshold, stop adjusting the brightness value of the second screen, at which time the brightness information around the first screen reaches the maximum Good fill light effect.

In this embodiment, the self-timer fill light method further includes:

If the angle of the second screen is equal to 90 degrees and the brightness value is adjusted to an upper limit, the brightness information of the surrounding environment of the first screen still does not reach the preset brightness threshold, then stop adjusting the second screen. Angle and / or brightness.

In this embodiment, if the angle of the second screen is equal to 90 degrees and the brightness value is adjusted to an upper limit, the brightness information of the environment around the first screen still does not reach the preset brightness threshold, then the The brightness information of the surrounding environment of the first screen cannot reach the preset brightness threshold. At this time, the brightness information of the surrounding environment of the first screen is already the best light supplement effect. Therefore, the dual-screen terminal is controlled to stop adjusting the first brightness threshold. Angle and / or brightness of the second screen.

It can be seen from the foregoing that the self-timer fill light method provided in this embodiment is based on adjusting the angle and / or brightness of another screen of the dual-screen terminal when it is detected that the user performs a self-timer operation on one screen of the dual-screen terminal. To achieve the best fill light effect, which not only can improve the self-timer effect, but also will not affect the self-timer screen display after the fill light preview image, greatly improving the user experience.

Example two

FIG. 3 is a schematic flowchart of a self-timer fill light method provided in Embodiment 2 of the present invention, and the method is executed by the dual-screen terminal shown in FIG. 1. As shown in FIG. 3, the self-timer fill light method provided in this embodiment may include the following steps:

In step S301, when it is detected that the user performs a self-timer operation through the first screen of the dual-screen terminal, the brightness information of the environment around the first screen is acquired.

Step S302, determine whether the brightness information is less than a preset brightness threshold; when the brightness information is less than the preset brightness threshold, proceed to step S303; when the brightness information is greater than the preset brightness threshold, proceed to step S304.

In step S303, the angle and / or brightness of the second screen of the dual-screen terminal is adjusted until the brightness information of the environment around the first screen reaches the best light supplement effect.

It should be noted that, since the implementation manner of steps S301 to S303 in this embodiment is the same as the implementation manner of steps S201 to S203 in the previous embodiment, details are not described herein again.

Step S304: Reduce the brightness of the second screen according to a third preset step until the brightness information of the environment around the first screen reaches the preset brightness threshold.

In this embodiment, if the brightness information of the surrounding environment of the first screen is greater than the preset brightness threshold value, it means that the brightness of the surrounding environment of the first screen is too high at this time, and photos taken in the brightness environment will be Overexposure, so the brightness of the surroundings of the first screen needs to be reduced at this time to achieve the best photo-filling effect. Since the brightness of the ambient light where the dual-screen terminal is located is too high at this time, adjusting the angle between the first screen and the second screen at this time has little effect on the brightness of the environment around the first screen, so Reduce the brightness of the surroundings of the first screen directly by adjusting the brightness of the second screen.

In this embodiment, when the processor of the dual-screen terminal adjusts the brightness information of the second screen, it controls the light sensor to monitor the brightness information of the surrounding environment of the first screen in real time. When the brightness information of the surrounding environment of a screen is reduced to the preset brightness value, adjusting the brightness value of the second screen is stopped, and at this time, the best shooting effect is achieved.

In this embodiment, the self-timer fill light method further includes:

Step S305: If the brightness information of the surroundings of the first screen does not reach the preset brightness threshold after the brightness value of the second screen is adjusted to a lower limit value, stop adjusting the brightness of the second screen.

In this embodiment, if the brightness value of the second screen is adjusted to the lower limit and the brightness of the surrounding environment of the first screen is still greater than the preset brightness threshold, the dual-screen terminal cannot adjust the brightness of the second screen by Brightness to make the brightness of the surroundings of the first screen reach the preset brightness threshold. At this time, the brightness information around the first screen has reached the best light supplement effect that the dual-screen terminal can achieve, so control The dual-screen terminal stops adjusting the brightness of the second screen.

In this embodiment, after detecting that the user performs a selfie operation through the first screen of the dual-screen terminal, the method further includes:

Adjusting the brightness value of the second screen to the preset brightness threshold.

In this embodiment, when it is detected that a user performs a self-timer operation through the first screen of the dual-screen terminal, the brightness value of the second screen is first adjusted to the preset brightness threshold, which can improve subsequent adjustments. The angle and / or brightness of the second screen enables the brightness information of the environment around the first screen to achieve the best light-filling efficiency.

It can be seen from the above that, compared with the previous embodiment, the self-timer fill light method provided in this embodiment can not only perform intelligent light fill in the dark environment of the self-timer, but also automatically reduce the self-timer environment when the self-timer environment is overexposed. Light to the optimal shooting brightness value; in addition, when a user is detected to perform a self-timer operation through the first screen of the dual-screen terminal, the brightness value of the second screen is adjusted to the preset brightness threshold, thereby The efficiency of subsequent adjustment of the angle and / or brightness of the second screen can be improved, so that the brightness information of the environment around the first screen can achieve the best light-filling effect.
