Based on information corresponding to a state of an object at a first time, information corresponding to the state of the object at a second time after the first time is estimated. The information corresponding to the state of the object at the second time is calculated by correcting the estimated information corresponding to the state of the object at the second time based on a focus detection result detected by a focus detection unit at the second time. Based on the information corresponding to the state of the object at the second time and information of time from the second time to a third time after the second time, an image plane position at the third time is predicted. Based on the image plane position predicted by a first prediction unit, driving of a focus lens is controlled.
