To enable an operator of a data center to easily obtain a state where an acceleration is received so as to determine presence/absence of video data while suppressing a communication volume in transmitting the video data.SOLUTION: A drive recorder 14 to be mounted on a vehicle includes a video acquisition section S110, a normal storage section S120, compression storage sections S130, S140, and compression transmission sections S160, S170. The video acquisition section acquires a video imaged by an imaging device 11. The normal storage section stores a video acquired by the video acquisition section as a normal video. The compression storage section stores a compression video being a video obtained by compressing a data amount of the normal video stored in the normal storage section. When it is determined that a transmission condition being a condition with a predetermined compression video has been established, the compression transmission section performs compression transmission processing being processing to define the compression video in a time including a time point when the transmission condition has been established as a transmission compression video, and then to transmit the transmission compression video to a predetermined transmission destination.SELECTED DRAWING: Figure 6

    【課題】映像データを送信する際の通信量を抑えた上で、データセンタの操作者が映像データの有無を判断できるよう加速度を受けた状況を把握しやすくする。【解決手段】車両に搭載されるドライブレコーダ14は、映像取得部S110と、通常記憶部S120と、圧縮記憶部S130、S140と、圧縮送信部S160、S170と、を備える。映像取得部は、撮像装置11により撮像された映像を取得する。通常記憶部は、映像取得部により取得された映像を通常映像として記憶する。圧縮記憶部は、通常記憶部に記憶された通常映像のデータ量を圧縮した映像である圧縮映像を記憶する。圧縮送信部は、圧縮映像をあらかじめ決められた条件である送信条件が成立したと判定した場合に、当該送信条件が成立した時点を含む時間における圧縮映像を送信圧縮映像として、当該送信圧縮映像をあらかじめ決められた送信先に送信する処理である圧縮送信処理を行う。【選択図】図6
