To provide a smell detection device, a smell detection method, and a program, which can suppress variations in accuracy of a measurement result.SOLUTION: A smell detection device 1 includes a smell sensor 10, environment information measurement means 11 and 12, smell information collection means 20, difference information acquisition means 21, and correction means 22. The smell sensor 10 detects information on a smell generated from a smell generation source 2. The environment information measurement means 11 and 12 measure environment information having correlation with a water vapor content contained in an ambient gas. The difference information acquisition means 21 acquires a difference water vapor content indicating a difference between environment information on the surroundings of the smell sensor 10 and environment information on the surroundings of the smell generation source 2. The correction means 22 corrects the smell information collected by the smell information collection means 20 on the basis of the difference information acquired by the difference information acquisition means 21.SELECTED DRAWING: Figure 1 【課題】計測結果の精度のばらつきを抑制することができる匂い検出装置、匂い検出方法及びプログラムを提供する。【解決手段】匂い検出装置１は、匂いセンサ１０と、環境情報測定手段１１，１２と、匂い情報収集手段２０と、差分情報取得手段２１と、補正手段２２と、を備える。匂いセンサ１０は、匂い発生源２から発せられる匂い情報を検出する。環境情報測定手段１１，１２は、周囲の気体に含まれる水蒸気量と相関性のある環境情報を測定する。差分情報取得手段２１は、匂いセンサ１０の周囲の環境情報と、匂い発生源２の周囲の環境情報との差を示す差分水蒸気量を取得する。補正手段２２は、匂い情報収集手段２０で収集された匂い情報を、差分情報取得手段２１で取得された差分情報に基づいて補正する。【選択図】図１
