✦ Synopsis

Field trials of the nonlinear color-appearance presenting the two color-appearance models by Hunt 2 and Nayatani. 3 model by Nayatani et al. were conducted by using the three chromatic-adaptation experiments by the Research Then, CIE established TC 1.34 Testing of Color Appearance Models at its Melbourne meeting in 1991 to Committee of CSAJ, Breneman, and McCann et al. Based on the preliminary analysis, the effective adaptation coef-conduct field trials for the above two models and for several succeeding proposed models. At present, this ficient a min was introduced to the model to account for the effect of incomplete adaptation found under test chro-committee's study is on going. TC 1.34 is asking its members to conduct the experiments for the field trials of the matic illuminant. It was confirmed that the nonlinear color-appearance model combined with a min predicted models and to publicize their results. The committee is also accumulating various data on the chromatic-adapta-quite nicely all the experiments. In addition, it was also found that the coefficient a min is different for different tion experiments reported so far.

At present, the accumulated data are the experimental color stimuli (object color or photographic transparency). In addition, the value of a min changes by changing results by the Research Committee on Color Appearance Experimentation of the Color Science Association of Ja-the adapting illuminance of the experiment in each of the two kinds of color stimuli used. ᭧ 1997
