The Influence Of Wavelength On The Neon Effect

In 2002,the Munsell color science laboratory proposed the Image Color Appearance Model(iCAM).iCAM can predict not only the simple color appearance phenomenon,but also can predict the color appearance phenomenon with complex spatial distribution,such as Simultaneous Contrast and Crispening.iCAM make the study of color appearance model one step further,but its function is very limited and need to continuously strengthen.For example,the prediction about Neon Color Spreading of iCAM is limited to some aspects.To promote the development of image color appearance model,first we need to conduct the thorough research to the complex color appearance phenomenon.Neon spreading effect is a typical color appearance phenomenon with complex spatial distribution.But so far researches on it are scarce and still in qualitative stage.The main research topics of this paper is the influence of wavelength to Neon Color Spreading and the establishment of mathematical model.In 1984,Yoshimichi Ejima studied the wavelength incentives used the Ehrenstein model.Based on the work put forward by Yoshimichi Ejima,we tried to use different model-Embedded model in order to obtain quantitative laws of the effect of wavelength incentives to Neon Color Spreading.First,we should to correction of the display and then try to achieve the value of wavelength convert to the display screen RGB values,completed each monochromatic light color of the wavelength to the realization of the display screen color.Secondly,completed the embedded model structure and the interface between the display and observer presented in the Matlab GUI interface to achieve the realization of different wavelengths combinations corresponding to different structural models.Finally,we organize the observer subjective evaluation experiment.The experimental data were processed to obtain the influence of wavelength on the Neon Effect,we can conclude to the following conclusion:Strong effects occur in this cluster:they are observed with wavelengths of the Segments ranging from 460 to 500 nm when they are combined with wavelengths of the Lattice ranging from 520 to 640 nm;Strong effects occur in this cluster:they are observed with wavelengths of the Segments ranging from 600 to 680 nm when they are combined with wavelengths of the Lattice ranging from 460 to 600 nm;The neon color effect is absent when the wavelengths of the Segments and the Lattice are the same.When the wavelength of Segments is greater than 540 nm,the wavelength of Lattice is greater than 640 nm,color spreading effect is not obvious.Finalization of mathematical modeling based on the experimental data.The quantitative description of the neon effect is the breakthrough point,also is the innovation point of the subject,but the mathematical model need to further improve.
