Abstract: A method and an apparatus for correcting distortions of image-taking video signals are provided. The method and an apparatus adopting the method are capable of reducing distortion generated in a taken image by correction of inter-frame and intra-frame hand movements 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 distortion observed in a taken image as distortion caused by a positional change, which occurs in the horizontal and/or vertical directions of the taken image at a photographing time as a positional change of the image-taking device. In accordance with the method, in a frame period of a taken image, an inter-frame correction quantity for a positional change of the device is detected and, on the basis of the detected inter-frame correction quantity, the positional change is corrected to eliminate a displacement observed when the frame changes to the next one as a displacement of the taken image.

Abstract: A lattice dividing unit 911 determines lattice lines to divide parameters of all points of a picture at every division and supplies distortion correction parameters (distortion correction coordinates) on the lattice points to a distortion correction memory (not shown). A polynomial of degree n coefficient deriving unit 902 expresses all distortion correction coordinates on each lattice line in the form of a function relative to positions on lattice lines and approximates the distortion correction coordinates by desired division polynomial of degree n. Further, a sample point deriving unit 903 compresses distortion correction parameters based upon the division polynomial of degree n obtained from the polynomial of degree n coefficient deriving unit 902.
