Abstract
A method of field sequential color image capture includes: optically capturing a scene frame-by-frame; filtering the scene through an active color shutter to produce a first color component set having plural first color components therein; detecting the scene with a color filter array area sensor, wherein each first color component of the first color component set of the scene is detected at different points in time within a frame; dividing the detected scene into a second color component set having plural second color components therein; aligning the second color component set in time for each frame interval; and combining the stored second color components into a frame image. A system for capturing a field sequential color image includes an optical capture mechanism for capturing a scene frame-by-frame in frame intervals which operates at a predetermined shutter speed; a color shutter for producing a first color component set having plural first color components therein, thereby modifying the spectral transmission of the scene as a function of time; a CFA area sensor for sensing the first color components, wherein each first color component of the scene is detected at a different point in time within a frame; an array field selector for dividing the scene into a second color component set having plural second color components therein; and a field-to-frame combiner for combining the second color components into a frame image.
