To provide a distance measuring device, a moving body, a distance measuring method and a program with which it is possible to accurately discriminate between the signal of reflected light from an object and a noise signal and improve the accuracy of measuring the distance to the object.SOLUTION: Provided is a distance measuring device for emitting light from a light projection unit, receiving reflected light by a light detection unit and acquiring a detection signal, and measuring the distance to an object on the basis of a time until the detection signal is acquired. The distance measuring device comprises: a first acquisition unit for acquiring information relating to the detection signal; a determination unit for determining the number of times detected by the light detection unit; a measuring unit for performing operation to find a time until reflected light is detected by the light detection unit or a value based on the time, as many times as the detection times; a count unit for counting the number of detection signals for each rank, corresponding to the time or the value based on the time, where the time or the value based on the time is a rank; a specification unit for specifying a rank that corresponds to the largest of total value of count values; thus, finding the distance to the object on the basis of a time that corresponds to the rank or a value based on the time.SELECTED DRAWING: Figure 8
