Abstract
The present invention provides a spectral imaging device characterized in that N images are captured with ambient light, and spectra can be obtained from the captured N images for spectral analysis. In particular, a filter device is employed to divide a spectral range of the ambient light into N spectral bands, and each capture corresponds to one spectral band.
