Abstract:
1. An imaging apparatus comprising: an imaging unit configured to photoelectrically convert an object image incident via a focus lens to acquire image data; a detection unit configured to detect a size of an object and a position of an object based on the acquired image data; an adjustment unit configured to execute focus adjustment by acquiring a focus signal indicating a focusing state of the focus lens based on the image data while moving the focus lens continuously, and moving the focus lens based on the focus signal; and a control unit configured to execute the focus adjustment regardless of whether the detected position of the object has changed or the detected position of the object has not changed while the detected size of the object has changed, and not to execute the focus adjustment regardless of whether the detected position of the object has changed or the detected position of the object has not changed while the detected size of the object has not changed, wherein the control unit is configured to determine whether the detected position of the object is changed after determining whether the detected size of the object is changed, wherein the focus adjustment is controlled so that the center position of a scanning range of the focus lens moves following the change of the detected position of the object, and the scanning range of the focus lens is an area narrower than a moving range of the focus lens.
