Embodiment 1

[0038] A method for brightness compensation of a front camera is provided in this embodiment, which can be used in mobile terminals such as mobile phones and ipads to perform brightness compensation for the front camera when shooting or video recording. The method includes the following steps:

[0039] S1. Obtain the brightness of the current environment. The current ambient brightness can be obtained through the built-in photosensitive sensor and other devices when shooting, so that the current ambient brightness can be obtained.

[0040] S2. Judging whether the brightness is less than the light compensation enable threshold, if it is less than, calculate the compensation brightness; if it is not less than, it is not necessary to perform light compensation, just shoot directly.

[0041]After obtaining the current ambient brightness, according to the brightness requirement of the selected shooting mode, the light compensation has a threshold. When the brightness is greater tha...

Embodiment 2

[0053] Provide a kind of mobile terminal with the brightness compensation function of front camera in this embodiment, this mobile terminal can be mobile phone, panel computer, ipad etc., the mobile terminal in this embodiment is mobile phone, as figure 2 As shown, it includes a face shell 1 and a rear shell that are snap-fitted. A mobile phone controller 2 is arranged in the cavity formed by the face shell 1 and the rear shell. A screen 3 and a front camera are arranged on the face shell 1. 4. At least one front flash 5 is also provided on the face shell 1, the brightness of the front flash 5 can be adjusted, and the mobile phone controller 2 is used to perform the brightness compensation of the front camera described in Embodiment 1 The device controls the brightness of the front flash 5 and the screen 3 .

[0054] As a preferred solution, the front flash 5 can be set to multiple, and the position can also be set according to needs, such as being set next to the front camer...

Embodiment 3

[0057] This embodiment provides a front camera brightness compensation device, such as image 3 shown, including:

[0058] The environment brightness acquisition unit 01 is used to acquire the brightness of the current environment;

[0059] The first judging unit 02 is configured to judge whether the luminance is less than the light compensation threshold;

[0060] Compensated luminance calculation unit 03, configured to calculate the compensated luminance when the luminance is less than the light compensation enable threshold;

[0061] The second judging unit 04 is used to judge whether the compensated brightness is smaller than the screen brightness compensation extreme value;

[0062] The screen compensation unit 05 is configured to turn on the screen and adjust its brightness to the compensation brightness when the compensation brightness is lower than the screen brightness compensation extreme value.

[0063] In a preferred solution, it also includes

[0064] A third ...

Abstract

The invention provides a front-mounted camera brightness compensation method and device. The method comprises following steps of firstly, obtaining brightness of a current environment; then judging whether the brightness is smaller than a light compensation starting threshold value or not; calculating compensation brightness if the brightness is smaller than the light compensation starting threshold value; judging whether the compensation brightness is smaller than a screen brightness compensation extreme value or not; and starting the screen and adjusting the brightness of the screen to the compensation brightness if the compensation brightness is smaller than the screen brightness compensation extreme value. According to the scheme, compensation is carried out by exclusively using a screen or a front-mounted flashlight; when the brightness compensation demand cannot be satisfied; the screen and the front-mounted flashlight can be used at the same time, thus satisfying the compensation demand; the current brightness can be compensated to the greatest extent; and therefore, the better photographing effects can be obtained under a disadvantaged photographing condition.

Description

technical field [0001] The invention relates to the field of photographing by mobile terminal equipment, in particular to a brightness compensation method for a front camera and a mobile terminal using the method. Background technique [0002] With the development of technology, electronic products are becoming more and more popular, and the functions of electronic products are becoming more and more abundant. Smartphones have become one of the necessary electronic products, and the functions of mobile phones are increasing, which have replaced many other consumer electronic products. For example, mobile phones can replace cameras and video recorders for taking pictures and videos. As the performance of the mobile phone is getting higher and higher, more and more applications can be used on the mobile phone, and the mobile phone also has many functions of a computer, and can perform image processing and the like. In order to obtain a better photo effect, in the case of dim ...
