1. An image stabilizing apparatus comprising at least one processor to implement: a feature point extractor configured to extract a feature point in a first input image captured by an image capturing apparatus; a movement amount detector configured to detect a movement amount of the image capturing apparatus in response to movement of the image capturing apparatus; a movement position predictor configured to predict a movement position, to which the extracted feature point is expected to have moved by the movement of the image capturing apparatus, in a second input image capture by the image capturing apparatus; a corresponding position detector configured to determine a position of a corresponding feature point in the second input image corresponding to the extracted feature point in the first input image after the movement of the image capturing apparatus; a comparator configured to compare the predicted movement position and the position of the corresponding feature point; and an image stabilizer configured to correct image distortion in the second input image caused by the movement of the image capturing apparatus, based on a result of the comparison.
