Portable electronic device and camera module therefor

A portable electronic device, comprising:

• a housing having a first side, a second side opposite to the first side, a first opening positioned on the first side for receiving a first light beam and a second opening positioned on the second side for receiving a second light beam;
• and
• a camera module positioned within the housing, comprising:
• a beam splitter having a first light input end for receiving the first light beam, a second light input end for receiving the second light beam from a second direction and a light output end for outputting the first or second light beam;
• a reflector positioned at the upstream of the first light input end of the beam splitter for receiving the first light beam from a first direction and redirecting the first light beam to the first light input end of the beam splitter, wherein the first direction is different from the second direction;
• and
• an image sensor positioned at the downstream of the light output end of the beam splitter for converting the first or second light beam outputted from the light output end into a corresponding signal.

A camera module for a portable electronic device, comprising:

• a beam splitter having a first light input end for receiving a first light beam, a second light input end for receiving a second light beam from a second direction and a light output end for outputting the first or second light beam;
• a reflector positioned at the upstream of the first light input end of the beam splitter for receiving the first light beam from a first direction and redirecting the first light beam to the first light input end of the beam splitter, wherein the first direction is different from the second direction;
• an image sensor positioned at the downstream of the light output end of the beam splitter for converting the first or second light beam outputted from the light output end into a corresponding signal;
• a first convex lens positioned between the light output end of the beam splitter and the image sensor;
• a first concave lens positioned between the reflector and the first light input end of the beam splitter for guiding the first light beam redirected by the reflector to the first light input end of the beam splitter;
• and
• a second convex lens positioned at the upstream of the reflector for receiving the first light beam and then guiding the first light beam to the reflector.
