Abstract
There is provided a light emitting and image sensing device for a scene. The device is formed in a semiconductor substrate and comprises a photosensor component for sensing an image of the scene. The photosensor component is responsive to incident light from the scene and provides an electrical signal representative of the image. There is also a photoemitter component for emitting a light signal representative of the electrical signal, and a coupling component connecting the photosensor component with the photoemitter component.
