Provided is a driving apparatus including: a calculation unit which calculates a driving amount of an optical element based on a detection position and target position of the optical element; a correction unit which generates a correction driving amount obtained by correcting the driving amount based on the driving amount, a parameter corresponding to a tilt of the optical element, and either the detection position or the target position, and outputs the driving amount and the correction driving amount; a first driving unit which applies a first driving force corresponding to either one of the driving amount or the correction driving amount to a first driving source out of driving sources for moving the optical element in a predetermined direction; and a second driving unit which applies a second driving force corresponding to another one of the driving amount or the correction driving amount to a second driving source.
