ABSTRACT:
To practice a method of transforming color sensation informations such that multidimensional physical informations and color sensation informations sensed by living bodies in response to the physical informations are non-linearly transformed therebetween, a multilayer feedforward type neural network is used for the purpose of accomplishing the foregoing transformation. The physical informations are provided in the form of data derived from multidimensional spectral distribution of light and the color sensation informations are provided in the form of sensitive colors each sensed by the living bodies as a psychological quantity relative to a certain color. An apparatus for carrying out the method includes an input section into which a physical quantity is inputted as an electrical signal, an information transforming section in which the inputted signal is transformed into a color sensation information representing psychological quantity of color and an output section from which the transformed color information is outputted. The information transforming section includes a multilayer feedforward type neural network.
