Abstract:
An image pickup apparatus includes an image sensor configured to capture an object image, and a controller by controlling energizing an actuator for an image stabilization operation that moves the image sensor. The controller switches an energization method for the actuator between a first energization method and a second energization method that has a response distortion of an actuator larger and a ripple current smaller than those of the first energization method, controls energizing the actuator by the first energization method in a first state that does not read a signal out of the image sensor during a charge accumulation of the image sensor, and controls energizing the actuator by the second energization method in a second state that reads the signal out of the image sensor after the charge accumulation.
