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

Claim 0:
1. An image processing apparatus comprising:
at least one processor or circuit configured to function as:
an electronic zoom unit configured to enlarge and output a predetermined region from a captured image;
a motion vector detection unit configured to detect a motion vector from a plurality of captured images;
a first representative vector calculation unit configured to calculate a first representative motion vector by setting a weight of a first motion vector detected in the predetermined region greater than a weight of a second motion vector detected in a region outside the predetermined region;
a second representative vector calculation unit configured to calculate a second representative motion vector by setting a weight of the second motion vector with respect to the first motion vector greater than the first representative vector calculation unit; and
a third representative vector calculation unit configured to calculate a third representative motion vector based on the first representative motion vector and the second representative motion vector,
wherein the third representative vector calculation unit
determines the third representative motion vector by setting a weight of the first representative motion vector greater than a weight of the second representative motion vector when an enlargement magnification in the electronic zoom unit is equal to or greater than a threshold, and
determines the third representative motion vector by setting a weight of the second representative motion vector greater than a weight of the first representative motion vector when an enlargement magnification in the electronic zoom unit is less than the threshold.
