Panasonic Corp developed a 2.1-Mpixel CMOS image sensor for camera systems capable of taking 3D movie with a single lens and announced it at ISSCC 2013
For taking 3D video, it is necessary to separate light into light entering the left eye and light entering the right eye and to make sure that the two types of lights come to different pixels of the CMOS sensor. To realize this, Panasonic employed a structure that combines a lenticular lens and mirror elements (digital micro lenses: DMLs) made by forming patterns whose size is smaller than light wavelength with a lithography technology.
