Abstract: The present invention provides an image capturing apparatus including an image capturing unit configured to photoelectrically convert an image of an object formed by an image capturing optical system to generate an image signal, a generation unit configured to generate, from the image signal generated by the image capturing unit, an evaluation value representing an in-focus state of the image capturing optical system, an adjusting unit configured to perform focus detection by adjusting relative positions of the image capturing unit and a focusing lens included in the image capturing optical system so as to maximize the evaluation value generated by the generation unit, and a determination unit configured to determine, during the focus detection by the adjusting unit, whether the object exists in a specific region defined in advance in the image capturing optical system in a range shorter than a predetermined distance.

Abstract: An image-pickup apparatus to which a lens unit that includes an image-pickup optical system including a focus lens is attachable includes an image sensor configured to photoelectrically convert an object image formed via the lens unit that has been attached, and to generate an image signal, and a controller configured to generate information on driving of the focus lens in the lens unit based upon the image signal and to provide focus control, the controller communicating data with the lens unit, wherein the controller transmits information on a driving target position of the focus lens to the lens unit in a first control, and transmits information on a driving direction and driving speed of the focus lens to the lens unit in a second control different from the first control.

Abstract: An imaging apparatus controls a movement of a second lens unit to compensate for an image-plane movement due to a movement of a first lens unit when a captured image is zoomed by moving the first lens unit, and controls the movement of the second lens unit to be performed within a range selected from data based on second information corresponding to an object distance. The data indicates a position of the first lens unit and a position of the second lens unit on an optical axis located behind the first lens unit, and is provided for each of object distances. The range of the movement of the second lens unit is changed according to a detection result by a second detection unit at a predetermined time.

Abstract: The optical apparatus includes a focus signal generator generating a focus signal from a photoelectrical conversion signal of an optical image formed by an optical system including a first lens unit for zooming and a second lens unit for focusing, a memory storing data indicating a relationship between positions of the first and second lens units, the data being generated for each predetermined in-focus distance. The controller moves the second lens unit in infinite and close directions. The controller changes a movement amount of a center position of the movement of the second lens unit in the infinite and close directions according to at least one selected from information on an operation of the optical system, information on a state of the optical system, and information on a photoelectric conversion operation of the optical image.

Abstract: A lens driving apparatus comprises: a zoom lens driven in an optical axis direction; first and second correction lenses driven in the optical axis direction; a storage unit that stores, for each predetermined focal length, positional relationships between the zoom lens, and the first and second correction lenses used for correcting a shift of an image plane upon driving of the zoom lens; a position detection unit that detects a position of the second correction lens; and a control unit that calculates driving amounts of the first correction lens and the second correction lens, and controls driving of the first and second correction lenses. The control means corrects an image plane position difference caused by a difference between a position of the second correction lens corresponding to a position of the zoom lens, and the detected position of the second correction lens, by moving the first correction lens.
