To accurately extract codes.SOLUTION: An imaging device 101 comprises: a photographing unit 111 that acquires first image data and second image data including images of objects that display codes 50 with non-visible light; and an image processing unit 142 that extracts the codes 50 on the basis of the first image data and second image data. The photographing unit 111 acquires the first image data with a plurality of first pixels having sensitivity to visible light, and acquires the second image data with a plurality of second pixels having sensitivity to non-visible light. The image processing unit 142 performs correction processing of multiplying at least one of the first image data and second image data by a correction coefficient, generates third image data from the difference between the first image data and second image data after the correction processing, and extracts the codes 50 on the basis of the third image data.SELECTED DRAWING: Figure 9

    【課題】高精度にコードを抽出する。【解決手段】撮像装置101は、非可視光によりコード50を表示する対象物の像を含む、第1画像データ及び第2画像データを取得する撮影部111と、第1画像データ及び第2画像データに基づいて、コード50を抽出する画像処理部142とを備え、撮影部111は、可視光に感度を有する複数の第1画素により第1画像データを取得し、非可視光に感度を有する複数の第2画素により第2画像データを取得し、画像処理部142は、第1画像データ及び第2画像データの少なくとも一方に補正係数を乗算する補正処理を行い、補正処理後の第1画像データ及び第2画像データの差分より第3画像データを生成し、第3画像データに基づいてコード50を抽出する。【選択図】図9
