A method, system, apparatus, and/or device that may include a first optic located a first distance from an optical receiver, the first optic being adapted to: receive environment content from a location in front of the first optic relative to the optical receiver; and alter a focal vergence of the environment content. The method, system, apparatus, and/or device may include a display located a second distance from the optical receiver, the display being is adapted to: receive the environment content from the first optic; and deliver the environment content and display content to a second optic. The method, system, apparatus, and/or device may include the second optic located a third distance from the optical receiver, the second optic being is adapted to: receive the environment content and the display content from the display; alter the focal vergence of the environment content; and alter a focal vergence of the display content.

A camera module and an electronic device are provided. The camera module includes a reflective member provided with a reflective and transmissive surface; a lens assembly and an image sensor, provided on a side of the reflective member; a filter reflection layer, provided on the reflective and transmissive surface; and a laser sensor, provided on a side of the reflective and transmissive surface facing away from an entrance surface. The filter reflection layer is capable of reflecting light of a first frequency band and transmitting light of a second frequency band. The first frequency band and the second frequency band are independent of each other.
