1. A photographic and projection module, comprising:
- a zoom lens;
an image sensor used to catch an external image;
a projection unit used to project light beams; and
a first reflective member disposed between the zoom lens and the image sensor or the projection unit;
wherein the zoom lens comprises a second reflective member;
wherein while the first reflective member is at a first position, the external image passes through the zoom lens then being caught by the image sensor; and
wherein while the first reflective member is at a second position, the light beams are emitted by the projection unit, then reflected by the first reflective member, passing through the zoom lens, and then projected out of the photographic and projection module.

10. An electronic system, comprising:
-
a housing having an opening; a cover lens covering the opening of the housing; and a photographic and projection module comprising; a zoom lens comprising a fixed reflective member arranged on an optical axis and inside the housing; a movable reflective member disposed following the zoom lens to change positions between a first position and a second position; an image sensor arranged at a first side of the movable reflective member; and a projection unit arranged at a second side of the movable reflective member; wherein when the movable reflective member is at the first position, first image beams pass through the cover lens, then being reflected by the fixed reflective member, and then focused on the image sensor, and when the movable reflective member is at the second position, the projection unit emitting the second image beams, which are reflected by the movable reflective member and the fixed reflective member, and then passed through the cover lens and the opening. - View Dependent Claims (11, 12, 13, 14, 15)
