Patent number: 10397466Abstract: An extreme value detection section performs a scan operation to detect and store an extreme value of a contrast and a direction of change in the contrast while performing scan driving of a focus lens, based on a direction indicated by a defocus amount. A determination start position calculation section calculates a determination start position corresponding to a position of the focus lens where a determination whether the scan operation is stopped is started, as a position precedent to an in-focus position based on the defocus amount. A control section stops the scan operation if a maximum value is detected during the scan operation before the focus lens reaches the determination start position and it is determined that the contrast decreases as a latest change during the scan operation after the focus lens reaches the determination start position.Type: GrantFiled: November 27, 2017Date of Patent: August 27, 2019Assignee: Olympus CorporationInventor: Satoru Ito
