<p>An image sensing system (20, 102) includes an IR notch filter (22) configured to block transmission of spectral energy having wavelengths in an interface region between the visible and the invisible spectra and enable transmission of spectral energy having wavelengths in at least the visible spectrum and the near-infrared (IR) spectrum, a digital image sensor (24, 210) including a two-dimensional array of pixel elements and configured to generate output signals at each pixel element as pixel data representing an image of a scene, and a color filter array (23) including a two-dimensional array of selectively transmissive filters superimposed on and in registration with the two-dimensional array of pixel elements. The color filter array includes a first group of selectively transmissive filters disposed to transmit spectral energy in one or more colors of the visible spectrum and a second group of gray color filters disposed to transmit spectral energy in at least the near-infrared (IR) spectrum.</p> |
