    摘要: An imaging apparatus includes an image pickup device that includes a first pixel group configured to photoelectrically convert an object image formed by a luminous flux from an imaging optical system, and a second pixel group which includes a plurality of pixels configured to photoelectrically convert a split pair of the luminous flux from the imaging optical system and a detecting unit configured to implement a first detection control that changes an imaging state of the image pickup device while detecting a contrast of the object image based on an output of the second pixel group, and then a second detection control that changes the imaging state of the image pickup device while detecting the contrast of the object image based on an output of the first pixel group.

    摘要: A lens driving apparatus comprises: a zoom lens driven in an optical axis direction; first and second correction lenses capable of being driven in the optical axis direction; storage means for storing, 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; position detection means for detecting a position of the second correction lens; and control means for calculating driving amounts of the first correction lens and the second correction lens, and controlling 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.

    摘要: An image capturing apparatus M comprises an optical-path-difference changing unit which changes an optical path difference between a first optical path L1 and a second optical path L2. A focus position of the image pickup by a first imaging device 18 varies (or moves) in a depth direction of a sample S according to the optical path difference changed by the optical-path-difference changing unit. Therefore, every time the optical-path-difference changing unit changes the optical path difference based on a predetermined target focus interval, while a focus control unit controls the focus position of the image pickup by the first imaging device 18, a stage control unit scans a stage 1 and the first imaging device 18 captures a first image, whereby the apparatus can readily capture Z-stack images consisting of a plurality of the first images in the depth direction of the sample S according to the change of the optical path difference.
