Summary:PROBLEM TO BE SOLVED: To enable a natural display image to be obtained with reducing sense of discomfort caused by mismatch between a background image generated from a pickup image in a target area and a heat map image obtained by visualizing residence information of a mobile within a target area when the heat map image is superimposed on the background image and displayed.SOLUTION: A residence condition analysis device has a residence information obtaining part 34 for obtaining residence information every predetermined measurement period on the basis of position information of a mobile which is obtained from a pickup image of a target area, a heat map image generator 35 for generating a heat map image by visualizing the residence information, a background image generator 36 for generating a background image from the pickup image, and a display image generator 37 for superimposing the heat map image on the background image to generate a display image. The background image generator subjects the pickup image to image processing of reducing discriminability of the mobile transferred to the pickup image to generate the background image. 【課題】対象エリア内での移動体の滞留情報を可視化したヒートマップ画像を、対象エリアの撮像画像から生成した背景画像に重畳して表示する場合に、背景画像とヒートマップ画像とが整合しないことによる違和感を低減して自然な表示画像が得られるようにする。【解決手段】対象エリアの撮像画像から取得した移動体の位置情報に基づいて、所定の計測期間ごとの滞留情報を取得する滞留情報取得部３４と、滞留情報を可視化したヒートマップ画像を生成するヒートマップ画像生成部３５と、撮像画像から背景画像を生成する背景画像生成部３６と、背景画像上にヒートマップ画像を重畳して、表示画像を生成する表示画像生成部３７と、を備え、背景画像生成部は、撮像画像に写った移動体の識別性を低減する画像処理を撮像画像に対して行って背景画像を生成する。【選択図】図５
