Abstract:
1. An image processing system for correcting an original image having distortion, comprising: an encoded parameter storage means for storing horizontal correction parameters and vertical correction parameters, the horizontal correction parameters indicating distances in the horizontal direction by which a horizontal correcting means adjusts designated pixels in the original image and the vertical correction parameters indicating distances in the vertical direction by which a vertical correcting means adjusts designated pixels in the original image; horizontal decoding means for decoding said encoded horizontal correction parameters supplied from said encoded parameter storage means; the horizontal correcting means for correcting distortion along the horizontal direction of said original image by performing one-dimensional horizontal interpolation operations between the designated pixels in the original image using said horizontal correction parameters decoded by said horizontal decoding means; vertical decoding means for decoding said encoded vertical correction parameters supplied from said encoded parameter storage means; and the vertical correcting means for correcting distortion along the vertical direction of said original image by performing one-dimensional vertical interpolation operations between the designated pixels in the original image using said vertical correction parameters decoded by said vertical decoding means, wherein said horizontal correction parameters and vertical correction parameters are obtained by performing grid split, at a grid splitting means, according to a control signal supplied from a user interface, and parameter compressing means for selectively compressing said horizontal correcting parameters at grid points obtained by said grid split and supplied to said horizontal decoding means, and for selectively compressing said vertical correcting parameters at said grid points and supplied to said vertical decoding means.
