PROBLEM TO BE SOLVED: To enable proper protection of privacy of persons and generation of an accurate traffic line analysis image in which residence information or transit information of persons is superimposed on a background image.SOLUTION: A traffic line analysis system has a camera device 100 and a server device 300 which are mutually connected to each other. The camera device 100 has an imaging unit 10 for imaging a prescribed imaging area, a background image generator 30 for generating a background image, a traffic line information analyzer 40 for extracting traffic line information regarding residence position or transit position in an imaging area of a mobile, and a transmitter 60 for transmitting, to a server device, respective background images generated by the background image generator before and after occurrence of an event, and traffic line information of the mobile extracted by the traffic line information analyzer. The server device 300 has an image generator 350 for generating a traffic line analysis image in which the traffic line information of the mobile is superimposed on the background image of the pickup image, and a display unit 450 for simultaneously displaying the plural traffic line analysis images before and after the event which are generated by the image generator. 【課題】人物のプライバシーを適切に保護し、背景画像に人物の滞留情報又は通過情報を重畳した正確な動線分析画像を生成する。【解決手段】動線分析システムは、カメラ装置１００とサーバ装置３００とが相互に接続される。カメラ装置１００は、所定の撮像領域を撮像する撮像部１０と、背景画像を生成する背景画像生成部３０と、移動体の撮像領域における滞留位置又は通過位置に関する動線情報を抽出する動線情報分析部４０と、イベント発生の前後におけるそれぞれの背景画像生成部により生成された背景画像と、動線情報分析部により抽出された移動体の動線情報とをサーバ装置に送信する送信部６０と、を備える。サーバ装置３００は、撮像画像の背景画像に、移動体の動線情報を重畳した動線分析画像をそれぞれ生成する画像生成部３５０と、画像生成部により生成されたイベントの前後における複数の動線分析画像を同時に表示させる表示部４５０と、を備える。【選択図】図２
