Abstract:
1. An image-processing method to correct a distortion of a signal representing an image taken by an image-taking device, the distortion caused by a positional change of the image-taking device at a photographing time of the taken image, said method comprising: (a) dividing a frame of said taken image into a plurality of image sub-segments, wherein each of the plurality of image sub-segments includes a plurality of lines having a start line and a designated line; (b) detecting a rate of a positional change for each of said plurality of image, sub-segments, the positional change occurring in at least one of a horizontal direction and a vertical direction at the photographing time of the taken image, wherein each rate of a positional change for each of said plurality of image sub-segments is based on a movement velocity vector detected by a velocity vector sensor; (c) determining at least one direction component of the detected rate of positional change for each of said plurality of image sub-segments; (d) for at least one designated line:
