  • Publication number: 20240147064
    Abstract: An imaging apparatus controls a focus position of an optical system by switching between a first mode where the focus position is moved alternately to first and second positions to determine an in-focus direction and a second mode where the focus position is moved in the in-focus direction. The apparatus includes an imaging unit that captures an image formed by the optical system, a detection unit that detects a vibration amount of the apparatus, a determination unit that determines, based on the vibration amount, a correction amount for reducing blurring, a correction unit that corrects the blurring by clipping a part of the image based on the correction amount, and a control unit that controls switching to the second mode if the in-focus direction is the same a predetermined number of times or more in succession. The predetermined number is changed based on the correction amount or the vibration amount.
