Abstract

A light receiving apparatus includes a light receiving unit (40) including a light receiving element (41) that receives light and photoelectrically converts the light into signals; a threshold varying unit configured to vary a threshold; a comparing unit (56) configured to compare signal values of the signals output from the light receiving unit (40) with a variable threshold changed by the threshold varying unit, and output signals indicating a comparison result; a counting unit configured to count, for each of the thresholds, a number of times that signals indicating that the signal value is larger than the variable threshold is output from the comparing unit (56); and a calculating unit configured to calculate a level of a noise included in the output signals based on a count result in the counting unit.
