1. A method of compensating an imager-created image for a distortion, said method comprising: a movement-vector detection process of receiving data of said imager-created image from an image taking device and detecting a movement vector for each screen of said imager-created image; an optical-zoom portion vector computation process of computing an optical-zoom portion vector corresponding to an image movement occurring on said imager-created image as a result of an optical zoom operation; an optical-zoom portion vector subtraction process of subtracting said optical-zoom portion vector computed in said optical-zoom portion vector computation process from said movement vector detected in said movement-vector detection process; a global hand-movement displacement vector computation process of computing a global hand-movement displacement vector for said imager-created image from said movement vector detected in said movement-vector detection process in the case of no optical zoom operation and computing a global hand-movement displacement vector for said imager-created image from a difference vector output from said optical-zoom portion vector subtraction process as a result of said vector subtraction in the case of an optical zoom operation; and a hand-movement compensation process of compensating said imager-created image for a distortion caused by a hand movement on the basis of said global hand-movement displacement vector computed in said global hand-movement displacement vector computation process.
