Problems solved by technology

[0003] However, when image reconstruction is performed on the data output by traditional CIS through demosaicing, the details of the image are prone to serious demosaic noise, which reduces the image quality, and the reconstruction process is cumbersome and the image processing efficiency is low

Embodiment Construction

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0026] For traditional CIS, whether it is FSI or BSI, the photodiode (photodiode, PD) in it all absorbs the light of 400nm-1100nm. Therefore, it is necessary to add filters of different colors to make it a single Pixels only absorb one color in RGB. At the same time, deep trench isolation (Deep Trench Isolation, DTI) is required for isolation between each pixel, so as to prevent incident light of different colors from entering adjacent pixels, thereby avoiding crosstalk between adjacent...

Abstract

The embodiment of the invention discloses an image processing method and device, and a storage medium. The image processing method is applied to the image processing device, the image processing device comprises a CIS, the CIS comprises a sub-wavelength pixel unit provided with at least three PD columns with three different size parameters, and the method comprises the steps of obtaining originaldata corresponding to incident light, wherein the original data comprises RGB data corresponding to the sub-wavelength pixel units, and one sub-wavelength pixel unit corresponds to one group of RGB data; determining color data corresponding to the incident light according to the RGB data; and obtaining a color image corresponding to the incident light according to the color data.

Description

technical field [0001] The embodiments of the present application relate to the field of image processing, and in particular, to an image processing method and device, and a storage medium. Background technique [0002] The traditional complementary metal oxide image sensor (CMOS Image Sensor, CIS) can include two different structures of Front Side Illumination (FSI) and Back Side Illumination (BSI), and whether it is FSI or BSI, Both need to set the filter to control the absorption of one color in RGB by the same pixel. Therefore, when the photographing device uses the CIS provided with an optical filter to acquire images, it needs to reconstruct the data output by the CIS into a generally viewable image format through demosaicing. Specifically, demosaicing is a digital image processing algorithm aimed at reconstructing a full-color image from incomplete color samples output by a photosensitive element covered with a color filter array (CFA). [0003] However, when image ...
