Claim One:
1. An image restoring apparatus for changing a value of each of continuous pixels to the next value thereof so as to obtain a proper image, comprising: input means for inputting a value of a pixel at present from given image data and a predetermined period; storage means for storing the value of the pixel at present and the predetermined period; momentum generating means for generating a value of a momentum; energy generating means for generating a gradient of a piecewise linear energy function, which has a simpler form than an original energy function and simplifies a calculation, corresponding to a given value of a pixel; integral means for performing digital processing of a simplified integration of a Hamilton equation for the predetermined period with initial conditions of the value of the pixel at present stored in said storage means and the momentum generated by said momentum generating means, said integral means calculating a resultant value of the pixel using the value of the period, the pixel at present, the momentum, and a gradient obtained from said energy generating means by giving a value of the pixel to said energy generating means; and output means for outputting the resultant value of the pixel as a value of the next alternative, and for restoring the proper image using the value of the next alternative.
