Patent ID: 8662766

Claim:
A light path adjustment apparatus comprising: a support plate comprising a first through hole through which light passes; and a plurality of optical units that move between an open location where the first through hole is opened by the optical units moving toward an outside of the first through hole and a closing location where the first through hole is divided into a plurality of regions by the plurality of optical units moving toward the first through hole, the plurality of optical units blocking at least a part of the light in the closing location, wherein each of the plurality of optical units comprises a liquid crystal device that operates according to an externally applied signal and passes or blocks the light according to a time dependence of the externally applied signal, wherein upon receiving a first signal from a control unit operating in a 2D photographing mode, the light path adjustment apparatus provides light to an imaging device when the plurality of optical units are disposed in the open location, to generate a single image incident through the first through hole, and wherein upon receiving a second signal from the control unit operating in a 3D photographing mode, the light path adjustment apparatus provides light to the imaging device when the plurality of optical units are disposed in the closed location, to generate a plurality of images incident through the plurality of optical units.
