Patent number: 10362236Abstract: In the image capturing apparatus, the controller controls an optical element, when a motion of the image capturing apparatus follows a motion of the object, by using first motion information obtained from a first detector to detect the motion of the image capturing apparatus and second motion information obtained from a second detector to detect the motion of the object. The calculator calculates 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. The controller uses the prediction information to control the optical element during the exposure time.Type: GrantFiled: August 22, 2018Date of Patent: July 23, 2019Assignee: Canon Kabushiki KaishaInventor: Masayuki Mukunashi

Patent number: 10244174Abstract: According to an aspect of the invention, an offset calculator calculates a first offset value from an angular velocity detection signal which is detected by an angular velocity sensor and determines a panning offset value as a second offset value. A camera shake correction controller controls driving of a shift lens group and performs camera shake correction on the basis of a signal obtained by subtracting the first offset value. A panning controller acquires angular velocity data of an object with respect to an imaging apparatus which is calculated on the basis of the signal obtained by subtracting the panning offset value.Type: GrantFiled: January 24, 2018Date of Patent: March 26, 2019Assignee: CANON KABUSHIKI KAISHAInventor: Masayuki Mukunashi
