A digital camera module includes a first barrel ( 10 ), a second barrel ( 20 ), a beam splitter ( 30 ), an IR-cut filter ( 40 ) and an image sensor ( 50 ). The first barrel receives a first lens element group ( 12 ) therein. The second barrel receives a second lens element group ( 22 ). The beam splitter is located between the first lens element group and the second lens element group. The presence of the beam splitter may effectively facilitate a decrease in the thickness needed to fit an optical path of a required length (to accommodate optics necessary for high resolution) within a mobile electronic device (e.g., phone, PDA), allowing a portion of the optical path to be positioned in the longer, vertical direction of the device body. This digital camera facilitates the miniaturization of a portable electronic device.
