Zusammenfassung:PROBLEM TO BE SOLVED: To properly protest privacy of persons reflected in a broad imaging area, and display a flow line analysis image capable of easily and correctly checking stay information on the persons in the broad imaging area or passage information thereon.SOLUTION: A camera device 100 comprises: an imaging unit 10 that photographs a different imaging area for each camera device; a background image generation unit 30 that repeatedly generates a background image of a photographed image in the imaging area at prescribed timing; a flow line information analysis unit 40 that extracts flow line information about a stay location or passage location in the imaging area of moving bodies included in the photographed image; and a transmission unit 60 that transmits the background image and the flow line information on the moving body to a server device every a prescribed transmission cycle. The server device 300 comprises: an image generation unit 350 that acquires a flow line analysis image for each camera device on the basis of overlapping of the background image of the photographed image on the flow line information on the moving body and generates a broad flow line analysis image using the acquired flow line analysis images; and a display control unit that causes a broad flow line analysis image to be displayed on a display unit.SELECTED DRAWING: Figure 2 【課題】広範な撮像領域に映る人物のプライバシーを適切に保護し、広域な撮像領域における人物の滞留情報又は通過情報を容易かつ正確に確認可能な動線分析画像を表示する。【解決手段】カメラ装置100は、カメラ装置ごとの異なる撮像領域を撮像する撮像部10と、撮像領域の撮像画像の背景画像を、所定のタイミングで繰り返し生成する背景画像生成部30と、撮像画像に含まれる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、所定の送信周期ごとに、背景画像と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と移動体の動線情報との重畳に基づく動線分析画像を、カメラ装置ごとに取得し、取得した複数の動線分析画像を用いて、広域動線分析画像を生成する画像生成部350と、広域動線分析画像を表示部に表示させる表示制御部と、を備える。【選択図】図2
