Abstract

The invention provides a high dynamic range image photographing method, a mobile terminal, and a computer readable storage medium. The high dynamic range image photographing method comprises the following steps: respectively controlling a first camera and a second camera to collect preview images, and displaying the preview images collected by the first camera on a photographing preview interface; acquiring M frames of preview images collected by the first camera; aligning and synthesizing the M frames of preview images, and generating a first image; acquiring N frames of preview images collected by the second camera; performing high dynamic range image synthesis processing on the N frames of preview images, and generating a second image; aligning and synthesizing the first image and the second image, and generating a high dynamic range image. The scheme meets the requirements of wide dynamic range and high definition image quality synchronously, and realizes real-time preview of the processing procedure.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a high dynamic range image shooting method, a mobile terminal and a computer-readable storage medium. Background technique [0002] HDR is the abbreviation of High-Dynamic Range. Compared with ordinary images, HDR can provide more dynamic range and image details, which are closer to the images seen by human eyes. The general implementation of the existing HDR technology is: turn on the camera and switch to the HDR mode; run the default 3A algorithm; click to take a photo; set different EV values ​​(exposure values), and capture a normal exposure RAW data (raw data) , one piece of overexposed RAW data, one piece of underexposed RAW data; enter the image signal processor (ISP); obtain a piece of normally exposed YUV data, a piece of overexposed YUV data, and a piece of underexposed YUV data Data; HDR algorithm synthesizes a piece of YUV data -> H: JPEG compressio...
