Abstract

Examples of the present invention provide an image processing method and mobile terminal.This image processing method includes: to obtain the multi -frame original image collected continuously in the camera; synthesize the first intermediate image by the preset algorithm;Get the second intermediate image; perform the image compression processing of the second intermediate image to obtain the final image. Among them, the multi -frame primitive image and the first intermediate image are all RAW format images with 10 than the special.The middle image is an 8 -than -wide YUV format image, and the final image is a JPEG format image with a wide range of eights.The image processing method provided by the embodiment of the present invention can obtain a wider dynamic range, less image noise, and more image details when using a mobile terminal to synthesize and enhance the processing.

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 communication technologies, functions of mobile terminals are becoming more and more diverse. For example, many mobile terminals have a camera function. During the process of taking a photo, the user can select a photo mode corresponding to the current environment (eg, lighting, scene, etc.) to take a photo. Currently, the camera mode includes an image enhancement mode, and the image enhancement mode includes a night scene mode, a high-dynamic range (High-Dynamic Range, HDR) mode, and the like. The image enhancement algorithm is mainly implemented in the hardware abstraction layer (HAL) of the electronic device. The input data is the image data in the YUV420 format, that is, the synthetic enhancement technology is performed on multiple image data frames in the Y...
