A multiple lens system includes at least one lens unit, at least one reflecting unit, a first image sensing element, a second image sensing element, and a processing unit. The processing unit is electrically connected to the first image sensing element and the second image sensing element. The processing unit controls at least one angle of the at least one reflection unit according to a capturing mode, changes at least one optical path of the at least one reflection unit, and selects at least one lens of the at least one lens unit. At least one image beam obtained by the selected at least one lens is reflected or projected to at least one of the first image sensing element and the second image sensing element through the at least one optical path.
