In order to better understand the present application, the content of the present application will be further described below in conjunction with specific embodiments:

In the present embodiment, the terminology used is for the purpose of describing particular embodiments, and is not intended to limit the invention. The singular forms "a", "the", and "the" Furthermore, the use of the terms "a", "an", etc. does not denote a limitation of the quantity, but rather the presence of at least one of the referenced items. It is further to be understood that the term "comprising", used in the specification, is intended to mean that the specified features, steps, and operations are present, but does not exclude the presence or addition of one or more other features, steps, operations and/or combinations thereof. In the meantime, the specific numerical ranges used in the present embodiment are only for the specific description of the embodiments of the present application, and the content of the disclosure is not limited.

Embodiment 1:

FIG. 1 is a flowchart of a method for photographing a mobile terminal provided in this embodiment, including:

Step 101: Acquire sensory information about a current environment and/or a physical state of the mobile terminal when the camera is enabled.

Step 102: Determine whether the acquired sensing information meets a corresponding preset threshold, and if yes, go to step 103; if no, go to step 104;

Step 103: Close the screen of the mobile terminal and complete the photographing according to the photographing instruction.

Step 104: Keep the screen of the mobile terminal on and take a normal photo.

In this embodiment, before the user turns on the camera to take a photo, the user also needs to set a power saving mode, where the energy saving mode indicates whether the system needs to acquire the sensing information, and of course, the energy saving mode may not be set, as long as the system obtains the sensing information through other systems. The manner of the present invention belongs to the scope of protection claimed in this embodiment. For example, the sensing information needs to be acquired as long as the camera is turned on.

In step 101, after the user turns on the camera, the user obtains the sensing information of the current environment and/or physical state of the mobile terminal.

Further, in this embodiment, the acquired sensing information of the current environment and/or the physical state of the mobile terminal includes the current acceleration information of the mobile terminal, the distance information between the mobile terminal and the user, and the light of the current environment of the mobile terminal. At least one of the brightness information, in the embodiment, the acquired sensing information of the current environment and/or the physical state of the mobile terminal is not limited to the three kinds of sensing information described above, and may be other possible and reasonable sensing information.

In step 102-103, when it is determined that the acquired sensing information meets the corresponding preset threshold, the screen of the closed mobile terminal is closed according to the photographing instruction; the preset threshold is preset distance information, acceleration information and ambient light brightness. The range value of the information, in the embodiment, the preset threshold value can ensure that the quality of the captured content is not affected after the terminal screen is closed.

In this embodiment, the current ambient light brightness information of the mobile terminal is preferably the light intensity of the surrounding environment where the mobile terminal is currently located when the user takes a picture, and when the ambient light intensity meets a certain threshold, the terminal screen is closed. The ambient light intensity threshold that is preferably set in this embodiment can ensure that the quality of the captured content is not affected after the terminal screen is turned off. For example, the set threshold is the ambient light intensity threshold range when the user is in an outdoor environment and is sunny. If the user is indoors or outdoors, the acquired ambient lightness information will not meet the previously preset threshold range. Therefore, When you take a photo, the terminal screen will not be closed. When the matching of the ambient light brightness information and the preset threshold is obtained, the screen of the mobile terminal is closed during the photographing process, and the power consumption of the mobile terminal can be saved under the premise of ensuring the quality of the photograph.

In this embodiment, the distance information between the mobile terminal and the user is preferably a distance value between the mobile terminal and the user's face when the user takes a photo; when the distance value meets a preset threshold, the mobile terminal screen is closed. , For example, the preset threshold value of the preset distance information is 3 cm - 10 cm (this threshold value is a specific numerical range enumerated in this embodiment for specific explanation.

In this embodiment, preferably, the closing of the terminal screen during the photographing process may be performed by acquiring at least one of the foregoing three types of sensing information, and the at least one sensing information of the acquired sensing information needs to match the preset threshold. For example, when the current acceleration information of the mobile terminal and the lightness information of the environment in which the mobile terminal is currently located are obtained, the acceleration information of the mobile terminal acquired at this time satisfies a preset threshold, and the ambient light luminance information is not satisfied. The preset threshold will also turn off the screen of the mobile terminal during the photo taking process.

In this embodiment, the acquired sensing information does not meet the preset threshold, and at least one of the acquired sensing information does not meet the corresponding preset threshold.

Further, in this embodiment, before the user closes the screen but does not complete the photographing, when the user needs to brighten the screen, the user can click on a specific button (such as a power button) or move in the form of a voice or a touch screen. The mobile terminal system sends a bright screen command, and after receiving the bright screen command, the mobile terminal re-opens the mobile terminal screen according to the bright screen command.
