Image stabilizing apparatus, image pick-up apparatus and image stabilizing method

An image stabilizing apparatus includes a motion vector calculating part (104) 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 (106) that receives the motion vector as input to calculate a shake correction amount, and an image transforming part (107) that performs geometric transformation of the image in accordance with the shake correction amount. The shake-correction parameter calculating part performs variation amount calculation (S502), variation amount correction (S503) and correction amount calculation (SS04) 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.
