Abstract
It is an object of the present technology to acquire distance measurement data having the maximum likelihood value by performing appropriate noise reduction. For this object, an arithmetic processing apparatus according to the present technology includes an operation processing part that performs processing of: calculating a first distance to a measurement object by emitting and receiving first irradiation light of which intensity is modulated by a first modulation signal of a first frequency; calculating a second distance to the measurement object by emitting and receiving second irradiation light of which intensity is modulated by a second modulation signal of a second frequency different from the first frequency; calculating a corrected first distance using first correction data that has been acquired; and determining the corrected first distance within an error range of the second distance as a third distance using the second distance.
