Abstract
A ranging device includes: a frequency distribution generation unit that generates a frequency distribution of a light reception count value counted in each bin period; a frequency distribution holding unit that holds the frequency distribution generated by the frequency distribution generation unit; and a phase setting unit that sets a phase of start timings of the bin periods with respect to periodic light emission timings to an object. In a case where a first frequency distribution acquired by a first phase in a first period is held in the frequency distribution holding unit, and then a second frequency distribution acquired by a second phase in a second period next to the first period is held in the frequency distribution holding unit, at least a part of the first frequency distribution is erased from the frequency distribution holding unit until the holding of the second frequency distribution is completed.
