色を指す言葉が示す色空間上の範囲は、その言葉を使う人間の文化的な背景や個人的な嗜好に大きく左右される。このような色を指す言葉が示す色の範囲を測定するための方法は一般的には存在しない。本研究では実験協力者に色見本帳に色を指す言葉に対応する色見本に印をつけてもらい、それをデジタルスチルカメラで撮影した画像から、物理的な色範囲に変換する手法の開発を行った。Color gamut of color word would be different by each personality, background of culture. In other hand, there is no standard method for measuring a gamut of color word. This paper reports a trial of developing a new method of measuring color gamut of color word, and some practical test result by pilot system. It use color chart with tag and digital still camera image as measuring source, then it detect list of color values as color gamut.In this method, all of participant have to do is paste tag to color chip that represent target color word. After that, measuring operator takes a picture it, then removes all tag and take a picture again. Color measuring system subtracts these two still images to make new image. In new image, non blank area shall represent participant checked color chips. Which chip represents which color could be known before measuring and it must be register to color measuringsystem. Color measuring system report a list of color value by tag position and pre-registered color chart values.
