Abstract: A distance measuring device has a plurality of light receiving elements each of which receives a reflected optical signal reflected by an object, and an image processor that generates a distance image in accordance with distances to the object, based on signal intensities and light reception timings of the reflected optical signal received by the plurality of light receiving elements, wherein the image processor detects a direction of the object, based on at least either the signal intensities of the reflected optical signal received by the light receiving elements or the distances to the object measured based on the reflected optical signal, and divides at least one or some of pixels included in the distance image, based on the direction of the detected object.
