A method for correcting distortions contained in a signal representing a taken image as distortions caused by a positional change, which occurs in horizontal and/or vertical directions of said taken image at a photographing time as a positional change of an image-taking device, said method comprising the steps of:
- dividing one screen segment of said taken image into a plurality of image sub-segments;
- detecting a rate of said positional change for each of said image sub-segments;
- and
- correcting a distortion caused by said positional change as a distortion in said taken image for each of said image sub-segments on the basis of said rate detected for said image sub-segment as said rate of said positional change.
