1. A camera device comprising:
a light output part configured to sequentially output a first output light signal and a second output light signal, which are emitted to an object, for one period;
a lens part including an infrared (IR) filter and at least one lens disposed on the IR filter and configured to collect a first input light signal and a second input light signal reflected from the object;
an image sensor configured to generate a first electrical signal and a second electrical signal from the first input light signal and the second input light signal which are collected by the lens part;
a tilting part configured to shift an optical path of the first input light signal and an optical path of the second input light signal according to a predetermined rule; and
an image control part configured to obtain a depth map of the object using the first electrical signal and a phase difference between the first output light signal and the first input light signal, and configured to obtain a two-dimensional (2D) image of the object using the second electrical signal,
wherein the tilting part shifts the optical path when an exposure cycle corresponding to a current optical path ends, and changes the optical path of the first input light signal and the second input light signal clockwise from a reference position.
