Conventional cameras capture 2D photographs at a single plane of focus. Acquisition of a 3D photograph with multiple planes of focus typically requires scanning the focus of a single camera [1], or using arrays of cameras or lenses [2]. This paper demonstrates a 150kpixel image sensor, which captures 3D scenes. The chip is manufactured in commodity 0.18μm CMOS and requires only a single convex lens at a fixed focal length in ambient light.
