  • Publication number: 20170302844
    Abstract: An image capturing apparatus includes: an image capturing unit; a focus detection unit that detects a focus position of an imaging optical system based on a phase-difference detection method; an imaging control unit that controls the image capturing unit to make the image capturing unit acquire pieces of light field data in one-to-one correspondence with a plurality of focus positions of the imaging optical system; and a generation unit that generates a refocused image corresponding to a focus position between the plurality of focus positions of the imaging optical system using the pieces of light field data, the generation depending on a direction of phase-difference detection by the focus detection unit and on a direction of parallax in the pieces of light field data.

  • Patent number: 9497375
    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.
