Problems solved by technology

[0003] However, due to the limitation of the hardware of the electronic device itself, it can only shoot images or videos with a small brightness range. When previewing or taking pictures or videos of scenes with a large difference between light and dark, it is easy to lose the details of bright or dark places.

Abstract

The embodiment of the invention discloses an image processing method and device, a storage medium and an electronic device, and the method comprises the steps: carrying out the alternate exposure according to a preset exposure sequence based on a plurality of exposure values, and obtaining an RAW image of a target scene; storing the RAW images into an image cache queue according to an exposure sequence; when preview or photographing or video recording is needed, obtaining multiple frames of newly-stored RAW images from the image cache queue, and the multiple frames of RAW images having different exposure values; synthesizing the multiple frames of RAW images to generate a synthesized image with a high dynamic range; and previewing or photographing or recording the target scene based on thecomposite image. Based on this, preview or photographing or video recording based on the high-dynamic-range image is realized.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method, device, storage medium and electronic equipment. Background technique [0002] With the continuous development of smart terminal technology, the use of electronic devices (such as smart phones, tablet computers, etc.) is becoming more and more popular. Most electronic devices have built-in cameras, and with the enhancement of the processing capability of mobile terminals and the development of camera technology, the performance of built-in cameras is becoming more and more powerful, and the quality of captured images is also getting higher and higher. While electronic devices bring convenience to people's daily photography, people's requirements for the quality of captured images are also getting higher and higher. [0003] However, due to the limitation of the hardware of the electronic device itself, it can only shoot images o...
