PROBLEM TO BE SOLVED: To provide a search device capable of more properly searching for a desired scene.SOLUTION: The search device includes a locus acquisition part, a state acquisition part, a query acquisition part and a search part. The locus acquisition part acquires locus information showing a movement locus of an object in a time series image. The state acquisition part acquires state information showing a state around the object in the time series image. The query acquisition part acquires a search query including the movement locus and the state around the object. The search part searches for an image meeting the search query among images included in the time series image on the basis of the locus information and the state information.SELECTED DRAWING: Figure 1 【課題】所望のシーンをより適切に検索できる検索装置を提供する。【解決手段】検索装置は、軌跡取得部と、状況取得部と、クエリ取得部と、検索部と、を備える。軌跡取得部は、時系列画像内での対象の移動軌跡を表す軌跡情報を取得する。状況取得部は、時系列画像内での対象の周辺の状況を表す状況情報を取得する。クエリ取得部は、移動軌跡および周辺の状況を含む検索クエリを取得する。検索部は、軌跡情報および状況情報に基づいて、時系列画像に含まれる画像のうち検索クエリに適合する画像を検索する。【選択図】図１
