Patent ID: 11871112
Assignee: CANON KABUSHIKI KAISHA
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. An image stabilization apparatus comprising at least one processor and/or circuitry which functions as:
a motion vector detector that detects a motion vector from images repeatedly output from an image sensor;
a first calculator that calculates a first image stabilization coefficient to be used for calculating an amount of translational shake based on the motion vector and an angular velocity of shake of an image capturing apparatus;
a second calculator that calculates a second image stabilization coefficient to be used for calculating an amount of translational shake based on acceleration and the angular velocity of shake of the image capturing apparatus;
a determination unit that selects either of the first image stabilization coefficient or the second image stabilization coefficient based on information about accuracy of detection of the motion vector by the motion vector detector; and
a translational shake calculator that calculates an amount of translational shake using the first image stabilization coefficient or the second image stabilization coefficient selected by the determination unit,
wherein, in a case where the information indicates that the accuracy is low, the determination unit selects the second image stabilization coefficient, and select the first image stabilization coefficient otherwise.
