Problems solved by technology

[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

Embodiment 1

[0098] The embodiment of the present application provides an image acquisition method, such as Figure 5 As shown, the image acquisition method includes the following steps:

[0099] S301. Receive a shooting instruction;

[0100] When the shooting is turned on, the image acquisition device receives a shooting instruction from the user; usually, after the shooting is turned on, the user will point the camera at the shooting scene, and click the shooting control to generate a shooting instruction, that is, the shooting instruction is received.

[0101] S302. When the de-diffraction function is turned on, collect multiple frames of images or a single frame of images according to the shooting instruction; wherein, the multiple frames of images include at least two frames of images with different exposures and the initial images collected under the preset exposure, and the single frame of images is an image collected at a preset exposure;

[0102] In the embodiment of the present...

Embodiment 2

[0160] Based on the same inventive concept of the first embodiment, further description will be made.

[0161] The embodiment of the present application provides an image acquisition device, such as Figure 9 As shown, the image acquisition device 9 includes:

[0162] a communication unit 91, configured to receive a shooting instruction;

[0163]The acquisition unit 92 is configured to acquire multiple frames of images or a single frame of images according to the shooting instruction when the de-diffraction function is turned on; wherein, the multiple frames of images include at least two frames of images with different exposures and an initial image collected under a preset exposure , the single frame image is the image collected under the preset exposure;

[0164] The de-diffraction unit 93 is configured to perform brightness differentiation processing on at least two frames of images and the initial image to obtain a differentiated area, remove the differentiated area fro...

Abstract

The embodiment of the present application discloses an image acquisition method and device, and a storage medium. The method includes: receiving a shooting instruction; when the de-diffraction function is turned on, according to the shooting instruction, collecting a multi-frame image or a single-frame image; wherein, the multi-frame The image includes at least two frames of images with different exposures and the initial image collected under the preset exposure, and the single frame image is an image collected under the preset exposure; the brightness difference processing is performed on at least two frames of images and the initial image to obtain the difference The differentiated area is removed from the initial image to obtain a de-diffraction image; or, the preset de-diffraction model is used to perform de-diffraction processing on a single frame image to obtain a de-diffraction image; the de-diffraction image is displayed.

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...
