摘要： A ranging apparatus includes a light emitting apparatus, a light receiving apparatus, and a processing circuit that controls the light emitting apparatus and the light receiving apparatus and that processes a signal outputted from the light receiving apparatus. The processing circuit causes the light emitting apparatus to emit first light that illuminates a first range in a scene, causes the light receiving apparatus to detect first reflected light produced by illumination with the first light and output first detection data, determines, on the basis of the first detection data, one or more second ranges that are narrower than the first range, causes the light emitting apparatus to emit second light that illuminates the second ranges, causes the light receiving apparatus to detect second reflected light produced by illumination with the second light and output second detection data, and generates and outputs distance data on the second regions on the basis of the second detection data.
