Abstract:
A method of field sequential color image capture comprising:optically capturing a scene frame-by-frame; filtering the scene through an active color filter to product a first color component set having plural first color components therein, thereby modifying the spectral transmission of the scene as a function of time, including operating a color field clock at a first predetermined rate and operating a frame control clock at a second predetermined rate, wherein the first predetermined rate is greater than the second predetermined rate, and wherein the first predetermined rate is set to about 2X that of the second predetermined rate; detecting the scene with a single, monochrome sensor, wherein each first color component of the first color component set of the scene is detected at a different point in time within a frame; dividing the detected scene into a second color component set having plural second color components therein, including temporally dividing the scene into U, Y and V color components; 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.
