<p>A distance measuring system (10) and a distance measuring method which use a time-of-flight (TOF) method. The distance measuring system (10) obtains a reference light quantity of reflected light which is a cumulative light quantity of the reflected light (Lr) during a reference period, obtains a measured light quantity of the reflected light which is a cumulative light quantity of the reflected light (Lr) during a measurement period, and calculates, on the basis of a ratio of the measured light quantity of the reflected light to the reference light quantity of the reflected light and a ratio of the reflected light incident period to the reference period, a reflected light incident period that is a period which is included in the measurement period and during which the reflected light (Lr) is incident upon photoelectric conversion elements (50, 50a) of a light-receiving device (14). Then, the distance measuring system (10) calculates the distance between the distance measuring system (10) and an object (W) on the basis of the reflected light incident period.</p> |
