An information processing device comprising: a means for acquiring colorimetric data that includes first through third color component values representing the skin pigment of a test subject; a means for acquiring from a camera an image of the skin of the test subject; a means for generating a display image for display on a display device on the basis of the image data; a means for converting the first through third color component values respectively to first through third pigment parameters related to a substance quantity representing an optical characteristic of the skin; a means for changing at least one of the first through third pigment parameters in accordance with an instruction from an operator; a means for converting the changed first through third pigment parameters respectively to first through third color component values; and a means for changing the display image on the basis of the converted first through third color component values.本發明之資訊處理裝置具備:取得包含表示受驗者之肌膚之色素之第1色成分值~第3色成分值之測色資料之機構;自照相機取得受驗者之肌膚之圖像資料之機構;基於圖像資料,產生顯示於顯示器之顯示圖像之機構;將上述第1色成分值~上述第3色成分值分別轉換成與表示肌膚之光特性之物質量相關之第1色素參數~第3色素參數之機構;根據操作人員之指示,變更第1色素參數~第3色素參數之至少1者之機構;將變更後之第1色素參數~第3色素參數分別轉換成第1色成分值~第3色成分值之機構;及基於轉換後之第1色成分值~第3色成分值而變更上述顯示圖像之機構。
