Abstract

A camera module includes an imaging lens system, an image sensor and a plurality of light-folding elements. The imaging lens system is configured to focus imaging light onto an image surface. The image sensor is disposed on the image surface. The plurality of light-folding elements includes at least one image-side light-folding element disposed on an image side of the imaging lens system, and each of the light-folding elements is configured to fold the imaging light from an entrance optical path thereof to an exit optical path thereof. At least one light-shielding mechanism is arranged on at least one of the entrance light path and the exit light path of the at least one image-side light-folding element. The at least one light-shielding mechanism has a minimal opening, and the minimal opening surrounds the imaging light in the at least one of the entrance optical path and the exit optical path.
