Method and apparatus for wide-band imaging based on narrow-band image data

An imaging method, comprising:

• receiving an intensity value of a first spectral channel associated with a pixel location, wherein the intensity value of the first spectral channel is based on electromagnetic radiation reflected from an object after being emitted from a narrow-band electromagnetic radiation source;
• defining an intensity value of a second spectral channel based on the intensity value of the first spectral channel, wherein the second spectral channel is associated with a spectral region of electromagnetic radiation different from a spectral region of electromagnetic radiation associated with the first spectral channel, and wherein at least a portion of the spectral region associated with the second spectral channel is outside of a spectral region of the narrow-band electromagnetic radiation source;
• and
• associating the intensity value of the second spectral channel with the pixel location.
