Zusammenfassung:To provide a new technology for assisting visual confirmation or read of information obtained by a polarization camera.SOLUTION: A processing device includes: image acquiring means for acquiring an original image captured by means of a polarization camera while a transparent object is illuminated by an illuminating device; polarized light extracting means for executing polarization extraction processing to extract polarization information, which is information relating to polarized light originating from specular reflection on the transparent object, for each pixel in the original image; image generating means for generating a polarization information image formed by converting the polarization information into an image, on the basis of a result extracted by the polarization extraction processing; and display means for displaying the polarization information image on a screen. The polarization information includes information relating to a polarization direction. The polarization information image includes a polarization direction image representing the polarization direction, which is one item of the polarization information, using pseudo-colors. The display means displays, on the screen, the polarization direction image together with an auxiliary image indicating association between the pseudo-colors and the polarization direction.SELECTED DRAWING: Figure 16 【課題】偏光カメラにより得られた情報の目視による確認や判読を支援するための新規な技術を提供する。【解決手段】処理装置が、照明装置により透明物体を照明した状態で偏光カメラによって撮影された元画像を取得する画像取得手段と、前記元画像の各画素について、前記透明物体での鏡面反射に由来する偏光に関する情報である偏光情報を抽出する、偏光抽出処理を実行する偏光抽出手段と、前記偏光抽出処理の抽出結果に基づいて、前記偏光情報を画像化した偏光情報画像を生成する画像生成手段と、前記偏光情報画像を画面に表示する表示手段と、を有し、前記偏光情報は、偏光方向の情報を含み、前記偏光情報画像は、前記偏光情報の一つである偏光方向を疑似色で表す偏光方向画像を含み、前記表示手段は、前記画面上に、前記偏光方向画像とともに、疑似色と偏光方向の対応関係を示す補助画像を表示する。【選択図】図16
