Shooting method and mobile terminal

Abstract

The invention provides a shooting method and a mobile terminal, relates to the communication field and solves problems of poor shooting performance of expansion technology in a dynamic range and poordynamic range expanding effect in the prior art. The method includes acquiring N groups of target image data collected by a camera; performing dynamic range expansion on at least two frames of imagesin each group of target image data and generating M frames of first synthesis image; performing image synthesis treatment on the M frames of the first synthesis image and generating X frames of secondsynthesis image; if receiving a shooting command, generating a picture according to the X frames of second synthesis image, wherein each group of target image data packet includes at least two framesof image and different images in each group of target image data are corresponding to different exposure parameters; N, M and X are all positive integers, M is smaller or equal to N and X is smalleror equal to M. According to the scheme of the invention, images of high dynamic range and high quality can be saved in real time through multi-frame synthesis treatment, the shooting performance is improved and the dynamic range expanding effect is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a photographing method and a mobile terminal. Background technique [0002] When users use ordinary cameras to take pictures and encounter the following scenes, it will be difficult to capture real pictures: shooting some luminous objects, such as the sun, lights, etc.; backlit scenes, scenes with large differences in the reflectivity of objects in the picture. However, due to the local adaptability of the human eye and the wide dynamic range of brightness perceived by the human eye, it is difficult to fully capture many details that the human eye can see with ordinary cameras and ordinary photographing methods. At present, many dynamic range expansion technologies, such as dynamic range expansion sensor technology, bracket exposure, etc., basically need to capture frames after triggering the camera action. The camera performance is poor, and the dynamic range expansion effect i...
