To solve the problem that in a situation where an on-vehicle camera tries to derive a photographing condition for obtaining a good-quality photographed image, the on-vehicle camera cannot derive the photographing condition on time in a point where a scene to be photographed varies rapidly, so that good-quality photographed image with high recognition rate of a photographic subject cannot be obtained.SOLUTION: The photographing system comprises: a photographing device; communication means that communicates with the photographing device; a photographing part that photographs a reference photographic subject at a specific point where the photographing device photographs and outputs a photographed image; an image recognizing part that derives a recognition rate at which the reference photographic subject is recognized in the photographed image on the basis of a result of comparison of photographed image information subjected to image processing on the basis of the output photographed image with correct-answer image information representing a prepared reference photographic subject; a condition deriving part that derives a photographing setting for improving the recognition rate of the reference photographic subject in the photographed image accompanying the derivation of the recognition rate, and derives a photographing condition which is utilized by the photographing device on the basis of the photographing setting; and a condition renewing part that transmits the photographing condition to the photographing device through the communication means to make the device to utilize the condition.SELECTED DRAWING: Figure 1

    【課題】車載カメラが良質な撮影画像を得る撮影条件を導出すると、撮影する光景が急激に変化する地点では、車載カメラでの撮影条件の導出が間に合わず、被写体の認識率が高い良質な撮影画像を得られない。【解決手段】撮影システムが、撮影装置と、撮影装置との間で通信するための通信手段と、撮影装置が撮影する特定地点において参考被写体を撮影し撮影画像を出力する撮影部と、出力された撮影画像に基づき画像処理された撮影画像情報と予め用意された参考被写体を表す正解画像情報との比較に基づき撮影画像において参考被写体を認識するときの認識率を導出する画像認識部と、認識率の導出に伴い撮影画像における参考被写体の認識率を向上させる撮影設定を導出し撮影設定に基づき撮影装置が利用する撮影条件を導出する条件導出部と、撮影装置に対し撮影条件を利用させるために通信手段を介して撮影条件を送信する条件更新部とを備えた。【選択図】 図1
