PROJECTOR DEVICE AND MOBILE TELEPHONE

摘要

A projector device includes: a projection unit having a light source and a projection lens whose focal length can be varied and projecting an image onto a projection surface by light flux outputted from the light source and passing through the projection lens; an imaging unit having an imaging lens whose focal length can be varied, imaging an object by the light flux passing through the imaging lens from outside, and acquiring the picked-up image; and a single drive source for generating a drive force for changing both of the focal length of the projection lens and the focal length of the imaging lens.
