IMAGE STABILIZING APPARATUS, IMAGE-PICKUP APPARATUS AND IMAGE STABILIZING METHOD

An image stabilizing apparatus includes a motion vector calculating part that calculates a motion vector between a plurality of images including a displacement caused by a motion of an image-pickup apparatus, a shake-correction parameter calculating part that receives the motion vector as input to calculate a shake correction amount, and an image transforming part that performs geometric transformation of the image in accordance with the shake correction amount. The shake-correction parameter calculating part performs variation amount calculation, variation amount correction and correction amount calculation based on the motion information between the plurality of images. The image stabilizing apparatus preserves a motion in video from an intended camera work and allows image stabilization for an unintended shake.
