Image capturing apparatus, control method thereof and storage medium storing control program therefor

A method of controlling an image capturing apparatus configured to perform image capturing of an object, the method comprising:

• controlling an optical element, when a motion of the image capturing apparatus follows a motion of the object, by using (a) first motion information obtained from a first detector to detect the motion of the image capturing apparatus and (b) second motion information obtained from a second detector to detect the motion of the object;
• and
• calculating prediction information on the motion of the object during an exposure time, by using the second information detected at multiple times before the exposure time,
• wherein the method controls the optical element during the exposure time, by using the prediction information.

A non-transitory computer-readable storage medium storing a control program as a computer program to cause a computer of an image capturing apparatus to operate, the image capturing apparatus being configured to perform image capturing of an object, the control program causing the computer to:

• control an optical element, when a motion of the image capturing apparatus follows a motion of the object, by using (a) first motion information obtained from a first detector to detect the motion of the image capturing apparatus and (b) second motion information obtained from a second detector to detect the motion of the object;
• and
• calculate prediction information on the motion of the object during an exposure time, by using the second information detected at multiple times before the exposure time,
• wherein the control program causes the computer to control the optical element during the exposure time, by using the prediction information.
