a method and device of image capturing comprising of timing control of sequentially placing the corresponding color filter to top of the image sensor allows an image sensor cell to capture multiple colors and produce output of multiple colors . thin films are applied to function as color filters to be turn on and off by electrical field . a semiconductor image sensor cell with micron - lens on top allows all light to penetrate into the photo diode and form variable voltage difference among different colors &# 39 ; sequence .
