AI Technical Summary

Technical Problem

While existing endoscopic techniques can ensure that the imaging highlights the details of lesions, they are difficult to maintain the visual quality of white light tones, and there is a significant difference in tones between narrowband light images and white light images.

Method used

An illumination module containing multiple narrowband light sources, including the main spectral bands that constitute white light, is used. The RGB image is decomposed into a white light image and multiple non-white light narrowband images. The narrowband images are then enhanced and fused with the white light image to form a narrowband enhanced target image.

Benefits of technology

While maintaining the white light tone, it improves the presentation of lesion details, providing more efficient and accurate endoscopic exploration, diagnosis and treatment capabilities.

Abstract

Provided are an endoscopic imaging apparatus and method, an electronic device, and a storage medium, which relate to the technical field of image processing. The apparatus comprises: a lighting module (101), configured to provide a lighting source and comprising a plurality of narrowband light sources of different colors, the plurality of narrowband light sources containing main spectral bands that constitute white light; an imaging module (102), configured to image reflected light after the lighting module (101) irradiates a target part of a patient, so as to acquire an RGB image; and a processing module (103), configured to decompose the RGB image into a white light image and a plurality of non-white light narrowband images, and to fuse, after enhancement processing is performed on the plurality of non-white light narrowband images, the plurality of non-white light narrowband images with the white light image to acquire a narrowband-enhanced target image, wherein the plurality of non-white light narrowband images respectively represent information formed in different tissue sites absorbing narrowband light of different wavelengths. In this way, on the basis of the full narrowband lighting source and the image decomposition-enhancement-fusion technology, the visual perception of white light tones is taken into account while ensuring that the imaging highlights details of the lesion.
