Abstract:
An apparatus (20) for recording a color image, comprises an image sensor (22) having a plurality of pixels (24) formed in a monolithic substrate. Each of the plurality of pixels (24) includes three floating gate semiconductor devices (80, 82, 84). A color tunable filter (30) is positioned between a photosensitive semiconductor device (86) and an electromagnetic radiation source. A FET transistor (130) has a drain (134) connected to the cathode (120) of the photodiode (86), and a source (136) connected to the anode (118) of the photodiode (86) and to control gates (94, 104, 114) of each of the three floating gate semiconductor devices (80, 82, 84). The color tunable filter (30) allows all desired combinations of colors to pass while each of the three floating gate semiconductor devices (80, 82, 84) are respectively selected to store the color image.
