Abstract

The invention provides a shooting method and a mobile terminal; the method comprises the following steps: using a color camera to obtain a normally exposed first image; using a monochrome camera to obtain at least two of the following three images: a normally exposed second image, an overexposure third image and an underexposure fourth image; synthetizing the at least two monochrome images so as to form a high dynamic range black white image; synthetizing the first image with the high dynamic range black white image so as to form a high dynamic range color image. The obtained high dynamic range color image is small in noisy points, rich in dynamic scope and image details, thus greatly improving the shooting image quality of the mobile terminal in a high dynamic range scene under night or insufficient light environments.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a photographing method and a mobile terminal. Background technique [0002] With the development and progress of science and technology, communication technology has developed rapidly and made great progress, and with the improvement of communication technology, mobile terminals have become an indispensable part of people's lives. The types of functions and performance requirements are getting higher and higher, such as Internet access function, audio function, shooting function and fast charging function, etc., have become necessary functions of smart terminals or mobile terminals. [0003] At present, it has become a trend to use a mobile terminal to take pictures or video. However, when using a mobile terminal to take pictures, especially at night or in a low-light environment, the dynamic range and image details of the captured image will be insufficient, and the no...
