Abstract

The present invention provides a shooting method and a mobile terminal. A color camera is used to obtain a first image with normal exposure, and a black and white camera is used to obtain at least two of the second image with normal exposure, the third image with overexposure and the fourth image with underexposure. A high dynamic range black-and-white image is synthesized from the at least two images, and then the first image and the high dynamic range black-and-white image are synthesized into a high dynamic range color image, so that the high dynamic range color image has less noise, and the dynamic range and image Rich in details, it can greatly improve the shooting quality of mobile terminals in high dynamic range scenes at night or in low-light environments.

Description

technical field [0001] The invention relates to the communication field, 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 considerable 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 the necessary functions of smart terminals or mobile terminals. [0003] At present, it has become a trend to use mobile terminals to take pictures or videos, but when shooting with mobile terminals, especially at night or in low-light environments, the dynamic range and image details of the captured images will be insufficient, and the noise will be high. Man...
