To allow a user of an image distribution device to understand the status.SOLUTION: An image distribution device includes a receiving part, a compression part, an operation part, and a distribution part. The receiving part receives imaging data imaged by an imaging device of an on-vehicle device mounted on a vehicle, and position information indicating a position of each on-vehicle device at each time. The compression part compresses the imaging data for which a prescribed time has elapsed since imaging by the imaging device, and generates compressed imaging data. The operation part calculates a traveling direction and a vehicle speed of the vehicle at a specific time using the on-vehicle device position of the position information at the specific time, and the on-vehicle device position of the position information immediately before the specific time. The distribution part generates a position image that displays on map data an icon indicating the on-vehicle device position and having a color according to the speed calculated by the calculation part, in a direction corresponding to the traveling direction of the vehicle.SELECTED DRAWING: Figure 5

    【課題】画像配信装置のユーザに、状況を把握させる。【解決手段】実施形態の画像配信装置は、受信部と、圧縮部と、演算部と、配信部と、を備える。受信部は、車両に搭載された車載装置の撮像装置が撮像した撮像データと、車載装置の時刻ごとの位置を示す位置情報とを受信する。圧縮部は、撮像装置が撮像してから所定の時間経過した撮像データを圧縮して圧縮撮像データを生成する。演算部は、特定の時刻における位置情報の車載装置の位置と、特定の時刻の直前における位置情報の車載装置の位置から、特定の時刻における車両の進行方向および速度を算出する。配信部は、演算部で算出した速度に応じた色の車載装置の位置を示すアイコンを、車両の進行方向に対応した向きで地図データ上に表示する位置画像を生成する。【選択図】図5
