Vibration reduction apparatus having feedback path for motion signal, and camera system

摘要

A vibration reduction apparatus estimates a reference value from a vibration detection signal, and determines a target drive position from a difference between the vibration detection signal and the estimated reference value. A driving unit drives a vibration reduction mechanism so that the vibration reduction mechanism makes a follow-up movement to the target drive position. The vibration reduction apparatus has a feedback path for feeding back a motion signal to the reference value. A feedback control unit for changing the feedback amount of the motion signal in accordance with a difference in an analytical condition of the motion signal is provided on the feedback path.
