摘要： A method for adjusting color channel signals based on spectral variations in the signal associated with a known source. In an embodiment of the present disclosure, the method may include receiving a first signal having an intensity value from an electromagnetic radiation source. In an embodiment of the present disclosure, the method may also include producing one or more second signals such that a response-ratio value calculated based on the one or more second signals satisfies a response-ratio condition associated with a spectral region of the first signal.

摘要： In one embodiment, an imaging method may include receiving an intensity value of a first spectral channel associated with a pixel location. The intensity value of the first spectral channel may be based on electromagnetic radiation reflected from an object after being emitted from a narrow-band electromagnetic radiation source. The method may further include defining an intensity value of a second spectral channel based on the intensity value of the first spectral channel. The second spectral channel may be associated with a spectral region of electromagnetic radiation different from a spectral region of electromagnetic radiation associated with the first spectral channel. The method may also include associating the intensity value of the second spectral channel with the pixel location.
