IMAGE CAPTURING APPARATUS, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM
An image capturing apparatus comprises an image sensor and a focus detection unit configured to, based on an image signal obtained by the image sensor while performing a scan operation that causes a focus lens to move along an optical axis of the imaging optical system, calculate a focus evaluation value and detect a position of the focus lens at which the focus evaluation value is a maximum, wherein the focus detection unit, in a case where the imaging optical system includes a reflective optical system in which a part of a light beam is blocked, sets a calculation method of the focus evaluation value or a control method of the focus lens during the scan operation based on information relating to a shape of the reflective optical system.
FOCUS ADJUSTMENT DEVICE, METHOD FOR CONTROLLING THE SAME, AND IMAGE CAPTURE APPARATUS
A focus adjustment device obtains a correction value for correcting a result of autofocus, from aberration information regarding at least one of an astigmatism, a chromatic aberration, and a spherical aberration of an imaging optical system, and focus detection information regarding the autofocus. The focus adjustment device then controls a position of a focusing lens that the imaging optical system has, based on a result of the autofocus corrected using the correction value. By correcting the result of the autofocus while considering at least a focus condition of a photographic image, a focus detection error caused by an aberration of the optical system can be accurately corrected.

IMAGING APPARATUS, IMAGING METHOD, AND PROGRAM
The present disclosure relates to an imaging apparatus, an imaging method, and a program that are capable of easily setting a type of a subject as a focusing target in each imaging. An image sensor acquires an image. An operation unit selects a type of a subject as a focusing target in each imaging of the image acquired by the image sensor. In the case where the type of the subject as a focusing target is selected by the operation unit, a microcomputer detects an area of the subject of that type from the image and sets the detected area as an in-focus area of the image. The present disclosure can be applied to an imaging apparatus, for example.
