Image stabilizing apparatus, its control method, image pickup apparatus, and storage medium

An image pickup apparatus comprising:

• an imaging unit;
• and
• an image stabilizing apparatus that includes:
• one or more processors;
• and
• a memory storing instructions which, when executed by the one or more processors, cause the image stabilizing apparatus to function as:
• a detecting unit configured to detect a motion vector in a plurality of areas made by dividing motion vector detecting frames set in a plurality of images sequentially output from an imaging unit;
• and
• a control unit configured to determine a motion vector of an object in the detected motion vector and to perform an image stabilization control based on the motion vector of the object,
• wherein the control unit determines a size of the object based on the motion vector of the object, and changes the motion vector detecting frame based on the size of the object and a position of the object.

A control method for an image stabilizing apparatus, comprising:

• a detecting step configured to detect a motion vector in a plurality of areas made by dividing motion vector detecting frames set in a plurality of images sequentially output from an imaging unit;
• and
• a control step configured to determine a motion vector of an object in the detected motion vector and to perform an image stabilization control based on the motion vector of the object,
• wherein the control step determines a size of the object based on the motion vector of the object, and changes the motion vector detecting frame based on the size of the object and a position of the object.

A non-transitory computer-readable storage medium configured to store a program that enables a computer to execute a method that includes the steps of:

• a detecting step configured to detect a motion vector in a plurality of areas made by dividing motion vector detecting frames set in a plurality of images sequentially output from an imaging unit;
• and
• a control step configured to determine a motion vector of an object in the detected motion vector and to perform an image stabilization control based on the motion vector of the object,
• wherein the control step determines a size of the object based on the motion vector of the object, and changes the motion vector detecting frame based on the size of the object and a position of the object.
