Problems solved by technology

[0003] In taking pictures, the sensitivity of the MONO camera is better than that of the RGB camera, so when shooting in the same brightness environment, the noise of the MONO image will be better than that of the RGB image. At this time, if you directly use the brightness information of the MONO image plus the color information of the RGB image For image fusion, changes in brightness will lead to problems such as color cast and color separation of the resulting image, which will affect the appearance of the image

[0032] Please refer to figure 2 , figure 2 The flowchart of the image enhancement method provided by the first embodiment of the present invention is shown. The image enhancement method includes the following steps:

[0033] Step S101: Obtain RGB images collected by the RGB camera and MONO images collected by the MONO camera.

[0034] In the embodiment of the present invention, the images of the RGB image and the MONO image are synchronized, that is, the RGB camera and the MONO camera capture objects in the same scene at the same time to obtain the RGB image and the MONO image.

[0035] In step S102, the RGB image is segmented to obtain a plurality of first images, and the MONO image is segmented to obtain a plurality of second images corresponding to the plurality of first images one-to-one.

[0036] In the embodiment of the present invention, after the RGB image and the MONO image are obtained, the RGB image and the MONO image are aligned at the pixel level using the image registr...

[0084] Please refer to Figure 7 , Figure 7 It shows a schematic structural diagram of an image intensifying apparatus 200 provided by the second embodiment of the present invention. The image enhancement device 200 includes an image acquisition module 201, an image segmentation module 202, and an image enhancement module 203.

[0085] The image acquisition module 201 is used to acquire the RGB image collected by the RGB camera and the MONO image collected by the MONO camera.

[0086] In the embodiment of the present invention, the image acquisition module 201 may be used to execute step S101.

[0087] The image segmentation module 202 is configured to segment the RGB image to obtain a plurality of first images, and perform image segmentation on the MONO image to obtain a plurality of second images corresponding to the plurality of first images.

[0088] In the embodiment of the present invention, the image segmentation module 202 may be used to perform step S102.

Abstract

The embodiment of the invention relates to the technical field of image processing and provides an image enhancement method and device, an electronic device and a storage medium. The method comprisessteps of acquiring an RGB image acquired by an RGB camera, and an MONO image acquired by an MONO camera; segmenting the RGB image so as to acquire multiple first images and carrying out image segmentation on the MONO image so as to obtain multiple second images corresponding to the first images; and traversing each first image and according to the definition of the to-be-processed first images andthe definition of the second images corresponding to the to-be-processed first images, carrying out image enhancement on the to-be-processed first images so as to obtain result images. Compared withthe prior art, according to the embodiment, color channels in the RGB image are processed as a whole, so the result images will not suffer from color cast and the images are attractive and are provided with high definition.

Description

Technical field [0001] The present invention relates to the technical field of image processing, and in particular to an image enhancement method, device, electronic equipment and storage medium. Background technique [0002] With the development of camera phones, consumers' demand for cameras with more powerful functions has gradually increased. Mobile phones that use dual cameras to improve the quality of photos have gradually become popular, and dual camera phones have more and more functions. A common dual-camera mode is the RGB+MONO mode, that is, a combination of a color camera and a black-and-white camera. Through image fusion of the images taken by the dual-camera, a better quality result image can be obtained. [0003] In taking pictures, the sensitivity of the MONO camera is better than that of the RGB camera, so when shooting in the same brightness environment, the noise of the MONO image will be better than that of the RGB image. At this time, if you directly use the br...
