PROBLEM TO BE SOLVED: To provide a technique for suppressing deterioration of estimation accuracy in emotion estimation processing based on an image.SOLUTION: An information processing device includes: a determination section for determining whether or not a vehicle is positioned within an accuracy deterioration area where estimation accuracy in emotion estimation processing to estimate an emotion of a passenger of a vehicle based on an image of the passenger imaged by an imaging section mounted on a vehicle; and an emotion estimation section for estimating an emotion of the passenger by performing different kinds of emotion estimation processing between cases where a vehicle is positioned within an accuracy deterioration area and where a vehicle is not positioned.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】画像に基づく感情推定処理の推定精度の低下を抑制可能な技術を提供することが望ましい。【解決手段】車両に搭載された撮像部によって撮像された車両の搭乗者の画像に基づいて搭乗者の感情を推定する感情推定処理の推定精度が低下する精度低下エリア内に車両が位置するか否かを判定する判定部と、車両が精度低下エリア内に位置するときと位置しないときとで異なる感情推定処理を実行して搭乗者の感情を推定する感情推定部とを備える情報処理装置を提供する。【選択図】図3
