Claim One:
1. A method of processing images for constructing a target image (Io) from adjacent images having a fixed frame line and referred to as source images (I1,. .. , Ii, Ij,. .. , In), said source and target images having substantially common view points, characterized in that the method comprises the steps of: (a) digitizing said source and target images; (b) determining a substantially common view point (P) to said source and target images, and a fixed orthonormal landmark (Px, Py, Pz) originated at said common view point (P); (c) generating, pixel by pixel, an address, for each pixel, in the target image (Io), so as to entirely cover said target image (Io); (d) calculating, on the basis of an address (Ao) of a current pixel referred to as an initial pixel (m') in the target image (Io), an orientation, in said fixed landmark, of a straight light ray (PM) passing through said initial pixel (m') and through said common view point; (e) selecting a source image (Ij) traversed by said straight light ray (PM); (f) calculating, from said orientation of the straight light ray (PM), an address (Aq) of a distortion corrected point (m), in said selected source image (Ij), said distortion corrected point (m) corresponding to said initial pixel (m'); (g) calculating a luminance value (F) at said distortion correct point m in said source image Ij; (h) assigning the luminance value (F) of said distortion corrected point (m) to the initial pixel (m') in the target image (Io); (i) repeating steps (d)-(h) for each pixel of the target image (Io), until all pixels of the target image (Io) have been processed.
