Abstract

The invention discloses a mobile terminal photographing device and method. The device comprises a first photographing module, a light ratio obtaining module, a light ratio comparison module, a light intensity adjustment module and a light supplement module; the first photographing module is used to control a mobile terminal to photograph a current scene and obtain an original picture when a photographing instruction is detected; the light ratio obtaining module is used to determine a dark portion and a bright portion in the original picture, and to obtain an actual light radio of the original picture; the light ratio comparison module is used to compare the actual light ratio with a pre-stored expected light ratio and obtain a difference value between the actual light ratio and the expected light ratio; the light intensity adjustment module is used to adjust flash intensity of a flash lamp of the mobile terminal according to the difference value, and is used to control the mobile terminal to photograph the current scene again by using the adjusted flash intensity and obtain a light supplement picture; and the light supplement module is used to supply light for the dark portion or the bright portion of the original picture according to the light supplement picture so as to adjust the actual light ratio of the original picture to be the expected light ratio. When an auxiliary light source and a light reflecting plate do not exist, an adjustment for the light ratio of the photographed picture of the mobile terminal is achieved, and the effect of the photographed picture is good.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal information interaction, in particular to a mobile terminal photographing device and method. Background technique [0002] In the current shooting technology, the photo light ratio (light ratio refers to the ratio of the average brightness of the dark part of the photo to the average brightness of the bright part) is generally directly determined by the lighting conditions of the shooting environment, or can only be determined by professional auxiliary light sources and The reflector regulates the light ratio of the shooting environment. However, when mobile terminal users take pictures outdoors, they generally do not carry auxiliary light sources and reflectors that are expensive, inconvenient to carry, and easy to break, so that users cannot conveniently adjust the photos taken. If the light ratio is low, the effect of shooting photos, especially portrait photos, is not good. C...
