摘要： An automatic focusing apparatus includes: a focus lens unit; a focus driver; a first focus detector that detects an in-focus state based on a phase difference; a second focus detector that detects an in-focus state using a signal from an image pickup element; a focus controller that controls the focus driver to perform focusing based on a first focus detection result and a second focus detection result; a movement detector that detects a movement of an object with components in a direction perpendicular to an optical axis based on an image signal obtained from the first focus detector; and a re-execution determination unit that determines whether to control the focus driver to re-execute focusing based on the first focus detection result and the second focus detection result that are newly detected after the execution of focusing and based on a movement detection result detected by the movement detector.
