Image acquisition method and device, and storage medium

Abstract

The embodiment of the invention discloses an image acquisition method and a device, and a storage medium. The method comprises the following steps: receiving a shooting instruction; when the dediffraction function is started, collecting multiple frames of images or a single frame of image according to a shooting instruction; wherein the multiple frames of images comprise at least two frames of images with different exposures and an initial image collected under a preset exposure, and the single frame of image is an image collected under the preset exposure; carrying out brightness differentiation processing on the at least two frames of images and the initial image to obtain a differentiation area, and removing the differentiation area on the initial image to obtain a dediffracted image; or, carrying out dediffraction processing on the single-frame image by utilizing a preset dediffraction model to obtain a dediffracted image; and displaying the dediffracted image.

Description

technical field [0001] The embodiments of the present application relate to image processing technologies, and in particular, to an image acquisition method and device, and a storage medium. Background technique [0002] Existing smartphones are equipped with cameras, and the lens of the camera is often covered with user fingerprints and sweat stains. Due to the existence of fingerprints and sweat stains, light diffraction will occur when the camera takes pictures, especially when the shooting brightness is high. When shooting an object, there are obvious diffraction fringes around the object in the captured image, which reduces the quality of the image, and the user usually finds the poor quality of the image when viewing the image, and the user needs to manually erase the use traces The image is re-taken, thus reducing the intelligence of the captured image. Secondly, some users will think that the camera has a problem of poor shooting quality, which also reduces the cred...

[0002] Existing smartphones are equipped with cameras, and the lens of the camera is often covered with user fingerprints and sweat stains. Due to the existence of fingerprints and sweat stains, light diffraction will occur when the camera takes pictures, especially when the shooting brightness is high. When shooting an object, there are obvious diffraction fringes around the object in the captured image, which reduces the quality of the image, and the user usually finds the poor quality of the image when viewing the image, and the user needs to manually erase the use traces re-capturing the image, and thus, reducing the intelligence of capturing the image

Secondly, some users will think that the camera has a problem of poor shooting quality, which also reduces the credibility of the captured images
