Abstract
A color image capture systems comprised of: a lens 110; a light sensitive sensor 114; a first wavelength dependent mask 120 located on an optical path 128 between the lens and sensor, wherein the first wavelength dependent mask 120 includes a first attenuation pattern for modulation of a light field; and a second wavelength dependent mask 130, wherein the second wavelength dependent mask includes a second attenuation pattern to modulate the modulated light field from the first wavelength dependent mask, the second wavelength dependent mask located on the optical path 128 between the first wavelength dependent mask and the sensor, further wherein the second wavelength dependent mask is separated from the sensor by a distance d.
