Image blur correction apparatus, control method therefor, image capturing apparatus, and storage medium

An image capturing apparatus, comprising:

• an image capturing sensor that captures a plurality of continuous images on a first cycle;
• and
• at least one processor and/or circuit configured to function as following units:
• a shake detection unit configured to detect a shake based on the plurality of images;
• a plurality of image blur correction amount obtainment units including
• a first blur correction amount obtainment unit configured to obtain, based on shake information obtained from a mounted lens apparatus through communication, image blur correction amounts that respectively correspond to partial images included among the plurality of continuous images, and
• a second image blur correction amount obtainment unit configured to obtain, based on a detection result of the shake detection unit and on the shake information obtained through the communication, image blur correction amounts that respectively correspond to partial images included among the plurality of continuous images with use of a method different from a method used by the first image blur correction amount obtainment unit;
• and
• an image blur correction unit configured to perform image blur correction with respect to the plurality of continuous images based on image blur correction amounts obtained by the plurality of image blur correction amount obtainment units,
• wherein at least one of the plurality of image blur correction amount obtainment units obtains the blur correction amounts respectively in correspondence with the plurality of continuous images.

A control method for an image blur correction apparatus, the control method comprising:

• obtaining shake information from a plurality of shake detection units configured to detect a shake;
• calculating an image blur correction amount of a captured image based on the shake information obtained from the plurality of shake detection units;
