A method and apparatus for correcting distortion of image-taking video
signals are provided. The method and apparatus adopting the method are
capable of reducing distortion generated in a taken picture by a focal
plane phenomenon caused by a hand movement or the like in an image-taking
apparatus employing an image-taking device of an X-Y address type. To be
more specific, this method is capable of correcting horizontal and/or
vertical directions observed in a taken image that is caused by a
positional change of the image-taking device. In accordance with the
method, one screen segment of the taken image is divided into a plurality
of image sub-segments. For each of the image sub-segments, the rate of
the positional change of the image-taking device is detected. Then, in
each of the image sub-segments, the distortion caused by the positional
change of the image-taking device in the taken image is corrected on the
basis of the rate of the positional change of the image-taking device
detected for each of the image sub-segments.
