Image stabilization apparatus and control method therefor

摘要

An image stabilization apparatus mounted on an image capturing apparatus, comprises a correction member capable of changing a position of an image on an image sensing plane by moving in a direction perpendicular to an optical axis, a position detection unit configured to detect a position of the correction member, a control unit configured to control driving of the correction member so as to have an amplitude larger than a pixel pitch of an image sensor, and an exposure control unit configured to control exposure of the image sensor, wherein the exposure control unit performs the exposure when the position of the correction member detected by the position detection unit moves by the pixel pitch.

1. An image stabilization apparatus mounted on an image capturing apparatus, comprising:
a correction member capable of changing a position of an image on an image sensing plane by moving in a direction different from an optical axis; a position detection unit configured to detect a position of said correction member; a control unit configured to control a pixel shifting driving of said correction member by a first waveform of a sinusoid which has an amplitude larger than a pixel pitch of an image sensor; and an exposure control unit configured to control exposure of the image sensor, wherein, after setting pixel shifting driving conditions, said control unit adds the first waveform to a second waveform of a sinusoid which is used to perform an image stabilization driving of said correction member when a predetermined position shift amount has been detected, and wherein said exposure control unit performs the exposure when the position of said correction member detected by said position detection unit moves by the pixel pitch.
