PROBLEM TO BE SOLVED: To enable a waiting pedestrian at a crosswalk to cross the crosswalk to be detected without requiring the pedestrian to operate a push button.SOLUTION: A crosswalk traffic signal system detects a waiting pedestrian at a crosswalk 3 waiting to cross the crosswalk by executing predetermined image analysis processing of an image captured by an imaging device 30 and controls a traffic signal for a pedestrian 20 and a traffic signal for a vehicle 10 related to the crosswalk 3 through recall control by detection of the waiting pedestrian. An imaging range of the imaging device 30 is set to include a waiting area 5 to wait for the traffic signal to cross the crosswalk 3. The crosswalk traffic signal system detects the waiting pedestrian by analyzing a line of sight of a person captured in a portion of the image of the waiting area 5 of the captured image. Also, the crosswalk traffic signal system lights a display device 40 to notify detection of the waiting pedestrian.SELECTED DRAWING: Figure 3

    【課題】押しボタン操作を必要とせずに横断歩道を渡ろうとする待機歩行者の検出を可能とすること。【解決手段】横断歩道用信号システムは、撮影装置30による撮影画像に対する所定の画像解析処理を行うことで、横断歩道3を横断するために待機している待機歩行者を検出し、待機歩行者の検出によるリコール制御によって、横断歩道3に係る歩行者用信号機20及び車両用信号機10を制御する。撮影装置30は、その撮影範囲が横断歩道3を通行するための信号待ちをする待機エリア5を含むように設定されており、撮影画像の待機エリア5の画像部分に写っている人物の視線を解析することで待機歩行者を検出する。また、待機歩行者の検出を、表示装置40の点灯によって報知する。【選択図】図3
