METHOD AND APPARATUS FOR DETERMINING SPECTRAL IMAGE, TERMINAL, AND STORAGE MEDIUM

The present application is applicable to the technical field of optics, and provides a method and apparatus for determining a spectral image, a terminal, and a storage medium. The method for determining a spectral image comprises: obtaining an original multispectral image, the original multispectral image comprising a plurality of pixel regions, and each pixel region corresponding to one original spectral band; determining one or more target spectral bands, and determining a quantum efficiency corresponding to each target spectral band in the one or more target spectral bands on each original spectral band; according to pixel value information of each pixel region and the quantum efficiency, calculating to obtain target pixel value information corresponding to each target spectral band in the one or more target spectral bands; and obtaining a target spectral image on the basis of the target pixel value information. According to embodiments of the present application, the spectral image of a specific spectral
