In this case, the luminance value λ1 ' is almost equal to the luminance value λ4 . Basically, the conformal mapping of a luminance λ6 is performed similarity with respect to the pixel BP of the 8th column of the third picture line. By this mapping. a new luminance value λ8 , is obtained with respect to the pixel BP exsisting on the rightmost edge part of the target segmant ZS is obtained.  The interpolation of luminance values is performed in among new luminance values λ1 ' and λ8 ' and, for example, an invariant luminance value 1.
