Apparatus for capturing a wide-color-gamut image includes a broadband electronic image sensor; optics gathering light from a scene and focusing an image formed by the gathered light along a light path onto the electronic image sensor; a filter interposed in the light path, constructed and arranged so as to allow individual wavelengths of the wide-gamut-color to pass through it in narrow bands of wavelengths having bandwidths narrower than a few tens of nanometers at each point in time; and a processor connected to the image sensor to capture a sequence of images synchronous with each narrow-band wavelength passed by the filter at each point in time, the processor combining the sequence of images into the wide-gamut-color image. Apparatus for projecting a wide-gamut-color image includes a wide-spectrum image source; optics projecting light from the image source to a display surface along a light path; a filter unit interposed in the light path, constructed and arranged so as to allow each individual wavelength of the wide-gamut-color to pass through it one, narrow-band wavelength at each point in time; and a processor connected to the image source to present a sequence of images synchronous with each narrow-band wavelength passed by the filter at each point in time, thus projecting the wide-gamut-color image.

Wide-gamut-color image formation and projection

Methods, luminaires and systems for matching a composite light spectrum to a target light spectrum are disclosed. Method embodiments may be optimized for simultaneously maximizing luminous output with minimal chromaticity error. Method embodiments may further be optimized for simultaneously minimizing both chromaticity and spectral error. Embodiments of the present invention may be used with composite light sources having four or more distinct dominant colors within the visible spectrum.
