Claim One:
1. A multi-point spectral system, comprising: a multiwavelength filter (MWF) including a plurality of narrow-bandpass filter (NBPF) units arranged in an array, each of the plurality of NBPF units having a respective predetermined central transmitted wavelength; an imaging lens provided to form a plurality of duplicated images of a scene onto the plurality of NBPF units, respectively; and an image capturing module including a color-image sensing element, wherein the color-image sensing element has an image-sensing region divided into a plurality of image-sensing areas corresponding to the plurality of NBPF units, respectively, and each of the plurality of image-sensing areas includes plural color micro-units arranged in an array, wherein the color micro-units include a plurality of red color micro-units, a plurality of green color micro-units, and a plurality of blue color micro-units, and each of the plural color micro-units has a wavelength band of responsive spectrum; wherein the MWF is located between the imaging lens and the image capturing module, and the image capturing module captures the plurality of duplicated images of the scene, and wherein each of the plurality of NBPF units includes a transmitted wavelength band, and the transmitted wavelength band of the NBPF unit is narrower than the wavelength band of responsive spectrum of the color micro-unit.
