摘要： A linear interpolating method and apparatus for color signals in a memory of a picture reproducing machine, wherein the stored signals are addressed in a three-dimensional fashion and a cubic interpolation unit in the memory is dissected into tetrahedra. It is determined which of these tetrahedra contains the interpolation point, and then the value at that point is interpolated from the known values at the vertices of the tetrahedron, using a certain method of linear interpolation. An apparatus is described for carrying out the method.
