A method for improving the spatial impression of depth of a supplied stereo image or of a sequence of stereo images, each with at least two supplied perspectives when representing the perspectives to be displayed on a stereoscopic display device, wherein the display device has a predetermined optimal disparity D opt and the maximum disparity for at least one stereo image deviates from the optimal disparity D opt, and the method comprises at least the following steps: - calculating or supplying a disparity card for the respective supplied stereo image, wherein the respective disparity in the disparity card identifies the difference of the pixel positions of an identical physical point in the leftmost and rightmost perspective of the supplied stereo image, and the maximum disparity d max is the maximum amount of all disparities in the disparity card of the respective supplied stereo image, and in the event that the maximum disparity deviates from the optimal disparity D opt, new leftmost and rightmost perspectives of the supplied stereo image are calculated using the calculated or supplied disparity card so that a maximum disparity results for the calculated leftmost and rightmost perspective, which is identical to the optimal disparity D opt of the supplied stereo image; wherein the display device has a predetermined optimal disparity D opt and a maximum increment change D F, and - in the event that the maximum disparity deviates from the optimal disparity D opt, new leftmost and rightmost perspectives are calculated, the maximum disparity amount of which is identical to the optimal disparity D opt or approaches the optimal disparity D opt by maximally the amount D F > 0; wherein - if D max < D opt, the factor F opt, by which the stereo base has to be increased, is F opt: = D opt / D max > 1, - if D max > D opt, the factor F opt, by which the stereo base has to be decreased, is F opt: = D opt / D max < 1, wherein each factor F opt is stored as F opt alt and is considered during the calculation of the following stereo image, and the change does not exceed an increment D F with 0 < D F < 1, wherein, if F opt < 1, a new F opt fulfills the condition F opt < = F opt alt + D F, and if this is not the case, then F opt: = F opt alt + D F is set; wherein, if F opt > 1, a new F opt fulfills the condition F opt > = F opt alt − D F and if this is not the case, then F opt: = F opt alt − D F is set, and F opt alt:= F opt is then stored for the following stereo image. - calculating or supplying a disparity card for the respective supplied stereo image, wherein the respective disparity in the disparity card identifies the difference of the pixel positions of an identical physical point in the leftmost and rightmost perspective of the supplied stereo image, and the maximum disparity d max is the maximum amount of all disparities in the disparity card of the respective supplied stereo image, and in the event that the maximum disparity deviates from the optimal disparity D opt, new leftmost and rightmost perspectives of the supplied stereo image are calculated using the calculated or supplied disparity card so that a maximum disparity results for the calculated leftmost and rightmost perspective, which is identical to the optimal disparity D opt of the supplied stereo image; wherein the display device has a predetermined optimal disparity D opt and a maximum increment change D F, and - in the event that the maximum disparity deviates from the optimal disparity D opt, new leftmost and rightmost perspectives are calculated, the maximum disparity amount of which is identical to the optimal disparity D opt or approaches the optimal disparity D opt by maximally the amount D F > 0; wherein - if D max < D opt, the factor F opt, by which the stereo base has to be increased, is F opt: = D opt / D max > 1, - if D max > D opt, the factor F opt, by which the stereo base has to be decreased, is F opt: = D opt / D max < 1, wherein each factor F opt is stored as F opt alt and is considered during the calculation of the following stereo image, and the change does not exceed an increment D F with 0 < D F < 1, wherein, if F opt < 1, a new F opt fulfills the condition F opt < = F opt alt + D F, and if this is not the case, then F opt: = F opt alt + D F is set; wherein, if F opt > 1, a new F opt fulfills the condition F opt > = F opt alt − D F and if this is not the case, then F opt: = F opt alt − D F is set, and F opt alt:= F opt is then stored for the following stereo image. the change does not exceed an increment D F with 0 < D F < 1, wherein, if F opt < 1, a new F opt fulfills the condition F opt < = F opt alt + D F, and if this is not the case, then F opt: = F opt alt + D F is set; wherein, if F opt > 1, a new F opt fulfills the condition F opt > = F opt alt − D F and if this is not the case, then F opt: = F opt alt − D F is set, and F opt alt:= F opt is then stored for the following stereo image.
