    Abstract: A camera device is provided. The camera device includes a light emitting portion configured to change a light path of light according to a first control signal and output the light along a first light path or a second light path, a light receiving portion configured to receive the light reflected by an object and generate an electrical signal, and a control portion configured to generate the first control signal which controls the light path of the light to be changed to the first light path or the second light path. Here, the light emitting portion outputs the light with a first pattern along the first light path or outputs the light with a second pattern along the second light path.
