女性ファッション雑誌の表紙における色彩分布の特徴

摘要

女性ファッション雑誌の表紙における色彩分布の特徴を調べた.表紙の画像データから得られる9個の特徴量を用いて，クラスタ分析を行い，雑誌を分類した.その結果，まず女性ファッション雑誌の表紙は，他のジャンルの雑誌とは明らかに区別されることがわかった.また女性フアツション雑誌は，対象とするファッション系統によってそれぞれ特徴的な表紙を有することもわかった.また，因子分析によって特徴量を要約し，4個の因子(あざやかさ，明るさ+細かさ，多色相性，トーンコントラスト)を得た.ティーン系の雑誌では「明るさ+細かさ」および「多色相性」の因子得点が高いこと，モード系の雑誌では「多色相性」の因子得点が著しく低いこと，ストリート系の雑誌では「トーンコントラスト」の因子得点が高いことなどがわかった.また，平均彩度と平均明度については雑誌による差異が明確であったが，色相についてはほとんど差異がなく，女性ファッション雑誌の表紙の平均色相はどれも赤からオレンジの領域にあることがわかった.%The author has investigated color distribution features in the cover of female fashion magazines. Using nine features derived from the image data of the cover, cluster analysis was performed to classify the magazines. In terms of the features of the cover, the female fashion magazines were found to be clearly distinguished from those of the other genres. It was also found that each female fashion magazine had distinctive cover depending on the fashion type of the magazine. Furthermore, factor analysis was performed to summarize the image features, and four factors, "average saturation", "average lightness and fineness", "multi-hue", and "tone contrast", were obtained. Scores for "average lightness and fineness" factor and "multi-hue" factor were high for most teen's magazines. Scores for "multi-hue" factor were significantly low for most mode magazines, and scores for "tone contrast" factor were high for most street fashion magazines. The female fashion magazines were distinguished clearly in terms of the average saturation and the average lightness of the cover, but there was no little difference for average hue. The covers of most female fashion magazines had similar average hue ranging from red to orange.
