Title:
SYSTEM AND METHOD FOR HIGH PRECISION MULTI-APERTURE SPECTRAL IMAGING
Document Type and Number:
Japanese Patent JP2023037629
Kind Code:
A
Abstract:
To provide a multispectral image system which can acquire an image of a wide-range tissue in a short time.SOLUTION: A multispectral image system comprises: image sensors 225A, 225B which are configured to receive light reflected by a tissue; apertures 210A, 210B which are arranged so as to pass a reflection portion of the light emitted to the image sensors to pass therethrough; multiband-pass filters 220A, 220B which are arranged above the apertures and configured to pass the three or more lights with prescribed frequency bands to pass therethrough; a memory which generates the multispectral image and stores a command for performing unmixing; and a processor which is configured to select the frequency band emitted from a light source by controlling the startup of each light emitter of the light source according to the command, receive signals from the image sensors, process the signal so as to generate a plurality of multispectral images, and perform spectral unmixing to generate a plurality of frequency band images of the tissue.SELECTED DRAWING: Figure 3A
