Abstract
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 syn…
