Abstract:
A method of field sequential color image capture comprising: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, thereby modifying the spectral transmission of the scene as a function of time, wherein said modifying includes operating a frame control clock at a first predetermined rate, operating a color field clock at a second predetermined rate, and operating an interlaced array field selector at a third predetermined rate, wherein the third predetermined rate is equal to the second predetermined rate, and wherein the second predetermined rate is greater than the first predetermined rate; 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; storing each second color component in a memory unit; combining the stored second color components into a frame image; and processing the frame image for color reproduction and format.
