To provide an electronic camera shake correction method and an apparatus thereof, and an imaging apparatus for reducing an arithmetic load and reducing an arithmetic processing time required for detecting a motion vector between two images to be subjected to the electronic camera shake correction.
In the electronic camera shake correction that calculates a motion vector due to a camera shake caused in image data of (N+1)th frame with respect to image data of N-th frame imaged by an imaging element and stored in a frame memory, the current motion vector is predicted on the basis of a motion vector obtained by image data of (N-1)th frame and the image data of the N-th frame, and a searching range of a compared image segmented from the image data of the (N+1)th frame with respect to a reference image segmented from the image data of the N-th frame is limited to a searching range A' on the basis of the prediction with respect to a substantial searching range A.
