To grade the total quality of the combination between landscape and light-up illuminations is quite ambiguous problem since it strongly depends upon the personal back-ground and subjectivity of the observers whether these are well matched or mismatched.
Therefore, we tried the fundamental research to measure fixed quantity-iation of the objective quality evaluation of the landscape in our laboratory.
The lighting effects of the actual landscape and so on are examined from getting the evaluation gauge which became the index of the evaluation.
