VISUAL ENVIRONMENT EVALUATION METHOD, VISUAL ENVIRONMENT NOTIFICATION METHOD, AND SELF-LUMINOUS BODY

摘要

PROBLEM TO BE SOLVED: To provide a visual environment evaluation method capable of evaluating a visual environment in a form closer to recognition by a human view.;SOLUTION: When a frequency component analysis and a contrast measurement are carried out together, correlation with an actually observed visual environment can be highly evaluated with high accuracy. A digital image introduced by a digital image introduction means 1 can be evaluated without any influence of illuminance on the periphery when components around a mean density value of a frequency component are eliminated in a digital image analysis means 2. Consequently, the correlation with the actually observed visual environment can be improved.;COPYRIGHT: (C)2005,JPO&NCIPI
