Abstract: An internally-housed camera in an electronic device includes a lens assembly and an image convertor located above the lens assembly. The lens assembly includes a lens and a reflector arranged at an acute angle with the lens. When incident light is received by the lens and reflected to the reflector, the reflector upwardly reflects one part of the incident light through 90 degrees to image convertor, and refracts the other part of the incident light to a back side of the reflector. The image convertor generates a corresponding image of the incident light.
