Title:
像ブレ補正装置、レンズ装置およびそれらの制御方法
Document Type and Number:
Japanese Patent JP7019337
Kind Code:
B2
Abstract:
According to an aspect of the invention, an imaging apparatus includes: a focal point detection unit configured to perform focal point detection on the basis of a phase difference between a plurality of image signals obtained by photoelectric conversion of light fluxes each passing through different pupil partial regions of an imaging optical system; an image blur compensation unit configured to compensate for image blur; and a control unit configured to set a position at which a vignetting amount occurring in a light flux passing through the imaging optical system is equal to or less than a predetermined value during a period in which the focal point detection is performed by the focal point detection unit as a center position of a driving amplitude to perform drive control of the image blur compensation unit.
