Photographing method and system of mobile terminal based on screen light-filling

Abstract

The invention discloses a photographing method and system of a mobile terminal based on screen light-filling. The method comprises the following steps: a mobile terminal detects the current environment brightness value before performing the photographing, and judges whether the current environment brightness value is less than a preset brightness value of the screen light-filling of the mobile terminal; when the current environment brightness value is less than the preset brightness value, a color temperature value of the current environment light is acquired; the type of the current environment light is judged according to the size of the color temperature value of the current environment light; the mobile terminal controls the screen display according to the type of the current environment light so as to fill light for the picture with the same hue with the current environment light, and then the photographing is performed after the screen hue matching is finished. Aiming at a condition of insufficient light, the color temperature closest to the current environment light is called to perform the light-filling by the screen, so that the brightness of the photographed picture is increased, the hue is more suitable for the reality, the picture hue is natural, and the color reproduction is more real.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and system for taking pictures of mobile terminals based on screen supplementary light. Background technique [0002] As mobile terminals are used more and more frequently, mobile terminals with a camera function have become an indispensable entertainment tool in people's daily life. At present, when mobile terminals take pictures, the screen fill light is realized by changing the brightness of the screen under a single color temperature of the screen to realize the fill light of the camera to take pictures, but the single color temperature will cause the color reproduction of the photos taken to be unrealistic and prone to color cast, especially when the screen brightness ratio is high. When the ambient light is bright, the color temperature of the screen light destroys the true color temperature of the environment, and the photos taken cannot truly ref...
