Claim One:
1. A method for the three-dimensional display of a scene on the basis of at least two views A n of the scene, with n=0,. .. , N−1, on a grid of pixels, the method being a computer-implemented method comprising: projecting a source view Q onto a projection surface P(x,y) with a horizontal coordinate x and a vertical coordinate y, and assigning an original viewing position B q to the source view Q, wherein the source view Q is composed of source pixels b q (x i , y j ) with rows j=1,. .. , J and columns i=1,. .. , I, and including at least one bit of color information stored in each source pixel b q (x i , y j ); providing a depth card T referenced to the projection surface P(x,y) and assigning the original viewing position B q to the depth card T, the depth card T comprising depth pixels t(x p ,y r ) with rows r=1,. .. , R and columns p=1,. .. , P, and including at least one bit of depth information stored in each depth pixel t(x p ,y r ), the depth information corresponding to a vertical distance to the projection surface P(x,y); assigning the original viewing position B q to a first view A 0 and, by horizontal shifting of the original viewing position B q , generating N−1 additional pairs of viewing positions B m , which differ from pair to pair and correspond to the other views A m , with m=1,. .. , N−1; determining bits of color information for pixels b n (x k , y l ) of the views A n , with rows l=1,. .. , L and columns k=1,. .. , K; combining the views A n according to a specified combination rule for three-dimensional display into a combination image which is displayed on the grid of pixels, wherein, according to the combination rule, for each of the views A n , only part of the pixels b n (x k , y i ) assigned to the respective view A n are displayed, and propagation directions are fixed for the views A n so that a viewer's left eye will perceive a different selection of views A n than the viewer's right eye and, thus, a visual impression of space is created; performing, if at least one of R≠L and P≠K, and the depth card T thus has a lower or higher resolution than the views A n , scaling of the depth card T with one of scaling factors S T x =K/P and S T y =L/R; performing, if at least one of J≠L or I≠K, and the source view thus has a lower or higher resolution than the views A n , a scaling of the source view with one of scaling factors S Q x =K/I and S Q y =L/J, creating a relief card Z(x, y) of the source view Q on the basis of the depth card T, with Z(x, y) being a continuous function in x and y, and the relief card Z(x, y) being connected with the source view Q; determining the bits of color information for pixels b n (x k , y l ) of the views A n , including— (i) creating a ray along a viewing direction from the respective viewing position B n to the respective pixel b n (x k , y l ) and extending the ray beyond the respective pixel into the depth, (ii) determining the intersection closest to the viewing position B n of the ray with the relief card Z(x, y), (iii) determining a source pixel b q (x s i , y j ) closest to the intersection, and (iv) assigning the respective pixel b n (x k , y l ) the color information of the source pixel b q (x s i , y j ), wherein the bits of color information for the views A n are determined only for the pixels b n (x k , y l ) to be displayed according to the combination rule.
