The reflecting assembly includes a first reflecting member and a second reflecting member corresponding to a position of the second lens. The first reflecting member is movable between a first position at which an optical path from the first lens to the image sensor is blocked but an optical path from the second reflecting member to the image sensor is not blocked, and a second position at which the optical path from the first lens to the image sensor is not blocked but the optical path from the second reflective member to the image sensor is blocked. Only one image sensor is used in the dual-lens camera system, which saves cost and takes up less internal space of the electronic device. ## Claims ### Claim 1 A dual-lens camera system comprising: a first lens assembly comprising a first lens;
