To precisely record a condition of an object after an occurrence of an event such as an accident.SOLUTION: An image recording device includes: an image data acquisition part for sequentially acquiring image data obtained by imaging surroundings of one's own vehicle; an event signal acquisition part for acquiring an event signal detecting an occurrence of a predetermined event for the one's own vehicle; a distance signal acquisition part for acquiring a distance signal detecting a distance from the one's own vehicle to an object existing near the one's own vehicle; and a writing control part. The writing control part writes, into a memory: the image data in a ring buffer format when the event signal acquisition part does not acquire the event signal; and, without overwriting, the image data including a period from a time point when the event signal is acquired to a time point when the distance signal acquisition part acquires the distance signal indicating that the object is distanced from the one's own vehicle more than a predetermined distance, when the event signal acquisition part acquires the event signal.SELECTED DRAWING: Figure 5
【課題】事故等のイベント発生後の対象物の様子を的確に記録する。【解決手段】画像記録装置は、自車両の周辺を撮像した画像データを逐次取得する画像データ取得部と、自車両に対する予め定められたイベントの発生を検出するイベント信号を取得するイベント信号取得部と、イベント信号取得部がイベント信号を取得した場合に、自車両から自車両の近傍に存在する対象物までの距離を検出した距離信号を取得する距離信号取得部と、イベント信号取得部がイベント信号を取得しない場合は、画像データをリングバッファ形式によりメモリに書き込み、イベント信号取得部がイベント信号を取得した場合は、イベント信号を取得した時点から、距離信号取得部が自車両から対象物が予め定められた距離以上に離間したことを示す距離信号を取得した時点までの期間を含む画像データを、上書きがされないようにメモリに書き込む書込制御部とを備える。【選択図】図5
