Abstract

Embodiments of the present invention provide an image processing method and a mobile terminal, wherein the mobile terminal includes a camera, an image signal processor ISP, and a digital signal processor DSP connected to the camera and the ISP respectively, and the method includes : In the shooting preview state, determine the timing data of the camera; control the DSP to continuously cycle to obtain the multi-frame preview images collected by the camera according to the timing data; if a photographing instruction is received, then determine the current shooting scene; based on the Screening out input images from the multi-frame preview images for the current shooting scene; performing image synthesis on the input images to generate a composite image; outputting the composite image to the ISP. Appropriate input images can be selected according to different shooting scenes by applying the embodiments of the present invention, so that more realistic and beautiful images can be obtained in different scenes.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image processing method and a mobile terminal. Background technique [0002] With the development of camera technology, it is possible to take clearer and more beautiful images, especially images in dark light have become one of the main aspects to measure the camera capability of a mobile terminal such as a mobile phone. How to allow users to take more realistic and beautiful images is our ultimate pursuit to continuously improve the level of photography. [0003] At present, it is limited to some shooting scenes, especially darker scenes. In order to obtain better images, it is necessary to show the details of dark areas and a wider dynamic range to show the highlights of night scenes. Therefore, one of the current main schemes is to use multiple normal frames (also known as normal exposure images) to synthesize the scheme, and the other is to add normal fram...
