Abstract
There is provided a light emitting and image sensing device for a scene. The light emitting and image sensing device is formed in a semiconductor substrate and comprises a photoemitter means for illuminating the scene with light, and a photosensor means for sensing an image of the scene. The photosensor means is responsive to incident light from the scene. In another embodiment of the present invention there is provided a light emitting and image sensing device for a scene. The light emitting and image sensing device includes a photosensor means for sensing the image of the scene, the photosensor means is formed in a first semiconductor substrate and is responsive to incident light from the scene, and a photoemitter means for illuminating the scene with light, the photoemitter means is formed in a second semiconductor substrate. The second semiconductor substrate is attached to the first semiconductor substrate.
