A ranging device including: a frequency distribution storage unit that stores a frequency distribution of the number of pulses detected in each predetermined bin period in time counting for each photoelectric conversion element; a region setting unit that sets a first region in which a part of the photoelectric conversion elements is arranged and a second region in which another part of the photoelectric conversion elements is arranged; and a storage condition setting unit that sets a storage condition of frequency distributions so that a class width of a first bin in a first frequency distribution corresponding to a photoelectric conversion element of the first region and a class width of a second bin in a second frequency distribution corresponding to a photoelectric conversion element of the second region are different and so that a storage capacity for the first and second frequency distributions does not exceed a predetermined value.
