Embodiment 1

[0027] figure 1 It is a flow chart of a photographing method according to an embodiment of the present invention. figure 1 The picture taking methods shown include:

[0028] Step 101, turn on the front camera of the mobile terminal.

[0029] The purpose of the embodiment of the present invention is: when the front camera is working, the light supplement element is used to supplement the light of the front camera, so as to improve the brightness of the environment where the front camera is located, so as to obtain clear image data.

[0030] In the embodiment of the present invention, the mobile terminal may be a mobile phone, a tablet, a notebook, and the like.

[0031] The mobile terminal is equipped with a front camera, and a front flash is installed near the front camera. The front flash can supplement the light of the front camera and improve the brightness of the environment around the front camera. The front camera has two functions of flash and fill light. When the ...

Embodiment 2

[0049] figure 2 It is a flowchart of a photographing method according to another embodiment of the present invention. figure 2 The picture taking methods shown include:

[0050] Step 201, turn on the front camera of the mobile terminal.

[0051] Step 202, detecting the distance between the mobile terminal and the photographed target.

[0052] Step 203, judging whether the distance between the mobile terminal and the target is greater than a distance threshold.

[0053] When designing this solution, the distance threshold is set in advance. If the distance between the mobile terminal and the target is greater than the distance threshold, it can be explained that the distance between the mobile terminal and the target is far away, and the screen brightness of the mobile terminal screen alone cannot To meet the shooting brightness requirements, it is necessary to select the front flash for supplementary light. If it is determined that the distance between the mobile termina...

Embodiment 3

[0066] image 3 is a block diagram of a mobile terminal according to an embodiment of the present invention. image 3 Mobile terminals shown include:

[0067] The front camera opening module 301 is configured to open the front camera of the mobile terminal.

[0068] The distance detection module 302 is configured to detect the distance between the mobile terminal and the photographed object.

[0069] The supplementary light component selection module 303 is configured to select a supplementary light component according to the distance, wherein the supplementary light component includes a display screen and a front flash.

[0070] The ambient light brightness acquiring module 304 is configured to acquire the ambient light brightness of the environment where the mobile terminal is located.

[0071] The brightness adjustment module 305 is configured to adjust the brightness of the supplementary light element according to the brightness of the ambient light and the distance.

Abstract

The embodiment of the invention discloses a photographing method and a mobile terminal. The method is used for the mobile terminal, and comprises the steps: starting a front-facing camera of the mobile terminal; detecting the distance between the mobile terminal and a photographed target object; selecting a light supplement element according to the distance, wherein the light supplement element comprises a display screen and a preposed flash lamp; obtaining the ambient light brightness of an environment where the mobile terminal is located; and adjusting the brightness of the light supplement element according to the ambient light brightness and the distance. Therefore, the method can determine the proper light supplement element to carry out the light supplement of the front-facing camera according to the detected distance between the mobile terminal and the target object, obtains the clear image data, and guarantees the experience effect of a user.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of information processing, and in particular, to a photographing method and a mobile terminal. Background technique [0002] With the continuous development of terminal technology, cameras have become one of the basic configurations of mobile terminals, and most smart terminals are equipped with front cameras and rear cameras. Users can use the front camera to take pictures, and can also use the front camera to interact with others in real time, such as video chatting. The front camera is used by more and more users. [0003] Compared with the rear camera, the configuration of the front camera is lower. In order to improve the shooting effect of the front camera, the main measure taken is to increase the brightness of the terminal screen. However, when the shooting object is far away or the light in the environment where the smart terminal is located is dark, the method of only using t...
