To provide a walking support system for sufficiently obtaining traffic light recognition accuracy and appropriately notifying a pedestrian of a traverse start.SOLUTION: When it is determined that existence of a traffic light is not recognized in an image acquired by a first image acquisition operation by a camera 20, the existence of the traffic light is recognized in an image acquired by a second image acquisition operation with enhanced accuracy in recognizing the existence of the traffic light. Though the second image acquisition operation has a possibility to reduce an object detection speed due to enhancement of the accuracy in recognizing the existence of the traffic light, timing to perform the second image acquisition operation is the timing when it is assumed that a pedestrian stops just before a crosswalk, so that a degree of request to raise the detection speed of an object such as a mobile body existing in a periphery is low. Thus, the traffic light recognition accuracy can be sufficiently obtained by the second image acquisition operation where the accuracy in recognizing the existence of the traffic light has priority.SELECTED DRAWING: Figure 3

    【課題】信号機の認識精度を十分に得ることを可能にし、歩行者に対する横断開始通知を適切に行うことができる歩行支援システムを提供する。【解決手段】カメラ20による第1の画像取得動作によって取得された画像において信号機の存在が認識されていないと判断された場合には、信号機の存在の認識精度が高められた第2の画像取得動作によって取得された画像において信号機の存在を認識する。この第2の画像取得動作は、信号機の存在の認識精度が高められており物体検出速度が低下してしまう可能性があるが、この第2の画像取得動作が行われるタイミングとしては、歩行者が横断歩道の手前で停止していることが想定され、周囲に存在する移動体等の物体検出速度を高める要求は低い。このため、信号機の存在の認識精度を優先した第2の画像取得動作によって信号機の認識精度を十分に得ることが可能になる。【選択図】図3
