Abstract

The embodiment of the invention provides a photographing method and a mobile terminal. The method comprises the following steps of: monitoring brightness information of a photographing scene; while monitoring that the brightness information of the photographing scene is less than a first brightness threshold value, controlling a black and white sensor camera to focus and image a target object in the photographing scene so as to obtain a black and white image; performing object feature identification of the black and white image so as to determine feature areas of various objects in the black and white image; and complementing colours of the feature areas of various objects in the black and white image so as to obtain a coloured image corresponding to the black and white image. According to the embodiment of the invention, the image is photographed by using the black and white sensor camera in a low-illumination environment; object feature area identification of the photographed black and white image is carried out; the colours of the feature areas of various identified objects are complemented correspondingly; therefore, the coloured image corresponding to the black and white image is obtained; imaging of the coloured image in the low-illumination environment is realized; imaging is clear; and the effect is good.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a photographing method and a mobile terminal. Background technique [0002] Most of the current mobile terminals only have color sensor (sensor) cameras, so when the mobile terminal captures images in a low-light environment (such as a night environment with only stars and the moon), there are generally insufficient photo brightness, unclear pictures, and noise. big question. [0003] In order to solve the above problems, the solution in the prior art is to add a black and white sensor (sensor) camera. Although it can achieve image imaging in a low-light environment to a certain extent, the image it presents is black and white, and there is no color presentation. [0004] It can be seen that the image imaging solution in the prior art cannot obtain a clear color image when imaging an image in a low-illuminance environment, and the imaging effect is poor.
