Abstract
An image capture apparatus which captures an object image formed by an imaging lens, comprises a focus detection unit which detects a focus position of the object image at a plurality of positions on an image sensing plane, a prediction unit which stores the past output from the focus detection unit, and predicts a locus of the focus position of the object image based on the stored output, thereby predicting the focus position of the object image at a predetermined time instant, a detection unit which detects a shift of the object image on the image sensing plane, and a control unit which changes the output from the prediction unit based on the output from the detection unit.
