Title:
IMAGE PROCESSING METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005870
Kind Code:
A1
Abstract:
Embodiments of the present application disclose an image processing method, which can be applied to color processing scenarios such as white balance and color restoration. The method comprises: by means of a color camera, acquiring a first image to be processed (101); by means of a multispectral sensor, acquiring first ambient spectral information (102), the first ambient spectral information and said first image corresponding to the same photographing scene; acquiring a white balance gain on the basis of said first image and the first ambient spectral information (103); and performing first processing on said first image, and obtaining a first target image (104), the first processing comprising white balance processing on the basis of the white balance gain. By introducing a multispectral sensor to collect ambient spectral information corresponding to an image to be processed, the image to be processed can be adjusted in real time. In addition, compared with the mode of estimating the light source in the existing technology, the quality of adjustment of a target image can also be improved.
