摘要： An image-pickup apparatus includes an image-pickup element photoelectrically converting an object image, a light-receiving sensor outputting a signal in accordance with a phase difference between a pair of object images, and a controller performing first focus control of controlling drive of a focus adjusting member based on a focus evaluation signal representing a contrast state of a video signal produced with the image-pickup element and second focus control of controlling drive of the focus adjusting member based on the signal in accordance with the phase difference. The controller stops the second focus control or switches focus control from the second focus control to the first focus control in response to a predetermined change found in the focus evaluation signal during the second focus control. The apparatus is capable of achieving an in-focus state smoothly and accurately with a hybrid AF.

摘要： An image pickup apparatus detects a subject based on an image signal output from an image sensing unit and acquires a size of the detected subject. The image pickup apparatus performs an automatic zooming operation such that a zoom lens is driven so as to increase or decrease the size of the subject so that the size of the subject becomes equal to a reference size of the subject. In a case where the difference between the size of the subject and the reference size has increased beyond a predetermined threshold value and the position of the zoom lens has reached a wide angle end or a telephoto end, the image pickup apparatus resets the reference size to be equal to the current size of the subject.

摘要： A focus adjustment apparatus comprises a moving unit configured to move a focusing lens, a focus adjusting unit configured to move the focusing lens such that the sharpness of an image obtained from an image pickup unit picking up an object image is increased, and an in-focus position measuring unit configured to measure an in-focus position in a different manner from the focus adjusting unit. The focus adjusting unit moves the focusing lens to the in-focus position measured by the in-focus position measuring unit when a direction of movement of the focusing lens in which the image sharpness is increased is matched with the direction of a current position of the focusing lens relative to the in-focus position measured by the in-focus position measuring unit, and does not move the focusing lens to the measured in-focus position when both the directions are not matched with each other.

摘要： An image pickup lens includes a controller and a manipulator position detector configured to detect a position of a manipulator configured to accept a manipulation used to move the lens. When the manipulation of the manipulator becomes valid and a difference between the position of the manipulator when the manipulation of the manipulator is invalid and the position of the manipulator when the manipulation of the manipulator is valid is equal or smaller than a threshold, the controller controls a movement of the lens from an initial position that is the position of the lens when the manipulation of the manipulator is invalid. When the manipulation of the manipulator becomes valid and the difference is larger than the threshold, the controller controls a movement of the lens from an initial position that is the position of the lens corresponding to the manipulator's position detected by the manipulator position detector.
