Abstract
In an image processing apparatus, a first motion detector calculates an angular velocity indicating a motion of an imaging apparatus body. A second motion detector calculates a movement amount of a motion of an object based on successively captured images. In addition, a motion vector calculating unit corrects the movement amount of the motion of the object based on the angular velocity, and calculates a motion vector of a main object based on the corrected movement amount.
Claims7
An image processing apparatus comprising:
- at least one processor executing computer executable instructions or at least one circuit which functions as:
- a first calculation unit configured to calculate first motion detection information indicating a motion of an imaging apparatus body based on information detected by an angular velocity detection unit;
- a second calculation unit configured to calculate second motion detection information indicating a motion of an object based on successively captured images;
- and
- a control unit configured to correct a movement amount relating to the motion of the object indicated by the second motion detection information in the images of a plurality of frames corresponding to a predetermined period based on the first motion detection information corresponding to each frame based on the first motion detection information, and calculate a motion vector of a main object based on the corrected movement amount, and
- wherein the control unit adds a frequency of the corrected movement amount relating to the motion of the object for the images of the plurality of frames and calculates the motion vector of the main object based on a frequency distribution obtained through the addition.
