Abstract :
This paper will develop a color measurement system that can describe the relation between device-dependent color space and device-independent color space. From the color theory, the relation might have some nonlinear phenomena. The nonlinear relation can be described by using the neural network with learning process. The back propagation algorithm is used for the learning process. The output of the neural network will provide color coordinate transformation. Therefore, the color chromaticity of the LCD can then be determined.
