Engineers from the German Fraunhofer Institute have developed a camera module for mobile devices that can fit into a slim smartphone with no protruding elements on the housing and no compromise on the quality of the pictures. On the rear panel of many devices, the cameras emerge due to the focal length of the lens as well as the overall fit of the component.
The Germans, however, offer a different approach – their development is equipped with four sensors rotated 90 degrees to point out. Small mirrors direct the light coming from the front or back of the device.
Engineers suggest the devices do not have separate front or rear cameras, and the switching between the two modes is done by turning the mirrors on the module. Obtained image modules comparable to those of modern smartphones.
The conceptual model has a mere 3.5 mm deviation – two times less than modern devices. Its resolution is 20 megapixels and offers automatic focus and optical stabilization.
