Abstract:
A camera device according to an embodiment of the present invention includes a light output unit that outputs an output light signal to be irradiated to an object, a lens unit that condenses an input light signal reflected from the object, an image sensor that generates an electric signal from the input light signal condensed by the lens unit and an image processing unit that extracts a depth map of the object using at least one of a time difference and a phase difference between the output light signal and the input light signal received by the image sensor, the lens unit including IR (InfraRed) filter, a plurality of solid lenses disposed on the IR filter and a liquid lens disposed on the plurality of solid lenses, or disposed between the plurality of solid lenses, the camera device further including a first driving unit that controls shifting of the IR filter or the image sensor and a second driving unit that controls a curvature of the liquid lens, an optical path of the input light signal being repeatedly shifted according to a predetermined rule by one of the first driving unit and the second driving unit, and the optical path of the input light signal being shifted according to predetermined control information by the other one of the first driving unit and the second driving unit.
