Abstract
A ranging apparatus includes a photodetector (10) including a light detecting device, a time measuring section (110) for measuring a period of time from an emission timing at which a light source (2) emits light to a detection timing at which the light detecting device detects the light, thereby acquiring measured values, a generating section (111) for generating a histogram of the measured values, and a calculating section (112) for calculating the distance up to a measurand on the basis of the histogram. The generating section generates the histogram on the basis of plural measuring conditions.
