ABSTRACT:
A tri-phosphor light having a reduced emission spectrum is matched with program encoding variables for a video encoder, such that the video encoder substantially encodes only those portions of the visible spectrum corresponding to wavelength bands centered around intensity peaks of the light's output, and substantially does not encode wavelengths which fall above or below the high-wavelength and low-wavelength peaks, respectively, of the light's spectral output.
