Abstract: An embodiment may provide a method for synchronizing a field of view of a distance measuring device including: a light source including one or more light source elements; and a light diffusion device through which light emitted from the light source passes, wherein the light diffusion device is divided into one or more regions, each of the light source elements of the light source is disposed with an independent region, and the intensity of light transferred from the light source elements is adjustable. The method may include: identifying a field of view (FOV) of a red, green, and blue (RGB) camera; and adjusting, based on a predetermined reference, the field of view of the distance measuring device such that the field of view of the distance measuring device corresponds to the field of view of the RGB camera.
