  • 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: 9405092
    Abstract: A control apparatus includes a first focus detection unit that performs focus detection by a phase difference method based on an image signal obtained from an image pickup element, a second focus detection unit that performs focus detection by a contrast method, and a control unit that performs focusing, the control unit performs the focusing, in a first mode, by using a detection result of the first focus detection unit, and performs the focusing, in a second mode, by selectively using one of the detection result of the first focus detection unit and a detection result of the second focus detection unit according to lens information, and the first mode is a mode in which the focusing is repeated, and the second mode is a mode in which a lens is stopped after the focusing.

  • Patent number: 8854530
    Abstract: The present invention is intended to display information of a focal length to be corrected or a focus position of a lens on a screen so that the user easily set a proper correction value even when the correction value of the in-focus position of the phase difference AF is different depending on the focal length or the focus position. A display apparatus of an image-pickup apparatus includes a lens information display 510, 531 configured to display lens information including at least one of information relating to a focal length of a lens unit and information relating to a focus position, a scale 503 that represents a correction value for correcting an in-focus position of a phase difference AF, and an indicator 520a-c, 530a-c that is used for setting the correction value corresponding to at least one of the focal length and the focus position.

  • Patent number: 8724011
    Abstract: The image pickup apparatus includes a first detector detecting a first in-focus position by a phase difference detection method using paired image signals, a controller controlling position of a focus lens a basis of the first in-focus position to perform focusing, a second detector detecting a second in-focus position by a contrast detection method, a calculating part calculating a correction value for correcting the first in-focus position in image capturing on a basis of difference between the first and second in-focus positions, and a determining part determining a level of reliability of the first in-focus position. The controller calculates the correction value when the level of reliability is a first level, and to restrict the calculation of the correction value when the level of reliability is a second level lower than the first level.
