An apparatus includes a control unit configured to control driving of a movable unit, a determination unit configured to determine a state in which the movable unit is pressed or twisted, and a decision unit configured to set the control unit to a first stop mode if the movable unit is in a pressed state, and to set the control unit to a second stop mode if the movable unit is in a twisted state.

Control apparatus, image pickup apparatus, control method, and memory medium

A driving control apparatus is configured to control a driving unit that moves relative to each other a vibrator that is excited to vibrate by applying a first driving signal and a second driving signal that have a phase difference with each other, and a contact member that contacts the vibrator. The driving control apparatus includes a first control unit configured to control the phase difference, and a second control unit configured to control a voltage amplitude of each of the first driving signal and the second driving signal. The second control unit controls the voltage amplitude so that a change rate of the voltage amplitude increases as an absolute value of the phase difference decreases.
