Method and apparatus for three-dimensional signal conversion |
摘要 |
A three-dimensional space formed by three-channel input signals is divided into a plurality of polyhedrons having vertices at points corresponding to a conversion table. A particular polyhedron is determined which is associated with the points corresponding to the three-channel input signals. The nonlinear interpolation is carried out using the conversion data corresponding to the vertices of the intended polyhedron thus determined and the conversion data corresponding to the vertices of the polyhedrons in surface contact with the intended polyhedron.
