1. An image capturing device, comprising:

  • a three dimensional (3D) device, including;

    a first level having a two dimensional (2D) image sensor comprising an array of first pixels; and

    a second level having a depth sensor comprising a plurality of second pixels sensitive to light in a near infrared wavelength range,wherein the plurality of second pixels of the depth sensor are lit by radiation that passes through the first level; and

    a processing device coupled to the 3D device and configured to perform image processing on pixel information captured by both the 2D image sensor and the depth sensor in order to generate 2D images and depth maps;

    wherein the processing device is configured to;

    adjust a sensitivity of the depth sensor in response to the 2D pixel information captured by the 2D image sensor by selectively actuating certain pixels of the plurality of second pixels when sensing light in the near infrared wavelength range based on aperture size;

    generate 2D images based on pixel information captured by the 2D image sensor and light intensity information captured by the second pixels of the depth sensor; and

    generate the depth maps based on depth information determined based on signals provided by the second pixels of the depth sensor and on 2D pixel information captured by the 2D image sensor.
