Abstract

The present invention provides a high dynamic range image shooting method, a mobile terminal, and a computer-readable storage medium, wherein the high dynamic range image shooting method includes: separately controlling the first camera and the second camera to collect a preview image, and The preview image collected by the first camera is displayed on the shooting preview interface; the M frame preview image collected by the first camera is obtained; the M frame preview image is aligned and synthesized to generate a first image; the M frame preview image is obtained; N frames of preview images collected by the second camera; performing high dynamic range image synthesis processing on the N frames of preview images to generate a second image; performing alignment synthesis processing on the first image and the second image to generate high dynamic range range image. This solution meets the requirements of wide dynamic range and high-definition image quality at the same time, and realizes the real-time preview of the processing process.

Description

Technical field [0001] The present invention relates to the field of communication technology, and 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 for High-Dynamic Range. Compared with ordinary images, HDR can provide more dynamic range and image details, which is closer to the image seen by the human eye. The general implementation of the existing HDR technology is: turn on the camera and switch to HDR mode; run the default 3A algorithm; click to take a photo; set a different EV value (exposure value), and grab a normal exposure RAW data (raw data) , An overexposed RAW data, an underexposed RAW data; enter the image signal processor (ISP); get a normal exposure YUV data, an overexposed YUV data, an underexposed YUV data Data; HDR algorithm synthesizes a piece of YUV data -> H: JPEG compression and save. [0003] The night scene mode is based on multi-fr...
