Abstract: According to one embodiment, disclosed is a method by which a camera module capable of acquiring depth information controls the output time point and the reception time point of light. By controlling both the output time point and the reception time point of light, the camera module can acquire the light of phases in which adjacent reception pixels differ from one another despite controlling light sources or reception pixels in line units.

Abstract: Embodiments provide a light-emitting device package including a light source, a lens disposed on the light source, and a diffuser located on at least one of the interior of the lens or a light emission surface of the lens, so as to diffuse light. The diffuser includes at least one of a light dispersing agent distributed in the interior of the lens, or at least one light diffusion structure located on at least one of the outside or the inside of the light emission surface of the lens. The light diffusion structure includes a rough surface formed on the light emission surface of the lens.
