Abstract

An image capturing apparatus comprises an imaging unit, a sensor unit, a first focus detection unit configured to detect a first in-focus position based on a pair of image signals, a second focus detection unit configured to detect a second in-focus position based on a signal output from the imaging unit, a control unit configured to control a position of the focus lens and control display indicating the focus detection areas, and a correction unit configured to acquire a correction amount for correcting the first in-focus position, wherein the correction unit determines a first focus detection area from which the correction amount is to be acquired while the focus lens is moved to the second in-focus position, and wherein the control unit controls the first focus detection area to be identifiable.

First claim

What is claimed is:

1. An image capturing apparatus comprising:
an imaging unit configured to generate an imaging signal by photoelectrically converting an object image formed by an imaging optical system including a focus lens;
a sensor unit including a plurality of pairs of sensors each of which generate a pair of image signals by photoelectrically converting an object image formed by the imaging optical system in correspondence with each of a plurality of focus detection area…
