To provide a technique of appropriately storing the state of tailgating driving while reducing storage capacity.SOLUTION: A drive recorder includes an image quality reducing unit for reducing image quality of a plurality of captured images which are respectively acquired by a plurality of cameras for capturing the periphery of a first vehicle and generating low-quality images, a low-quality image recording unit for making a recording medium store the low-quality images which are respectively generated from the plurality of captured images, a tailgating driving detection unit for detecting the tailgating driving of a second vehicle traveling around the first vehicle based on the plurality of captured images, and a high-quality image recording unit for making the recording medium store captured images in which the second vehicle is captured among the plurality of captured images with higher image quality than that of the low-quality images when the tailgating driving is detected.SELECTED DRAWING: Figure 7

    【課題】記憶容量を削減しつつ、煽り運転の状況を適確に記憶する技術を提供する。【解決手段】第一車両の周囲を撮影する複数のカメラから夫々取得した複数の撮影画像の画質を低減させ、低画質画像を生成する画質低減部と、前記複数の撮影画像から夫々生成された前記低画質画像を記憶媒体に記憶させる低画質記録部と、前記複数の撮影画像に基づいて、第一車両の周囲を走行する第二車両の煽り運転を検出する煽り運転検出部と、前記煽り運転が検出された場合に、前記複数の撮影画像のうち、前記第二車両が撮影されている撮影画像を前記低画質画像よりも高い画質で記録媒体に記憶させる高画質記録部とを備えるドライブレコーダ。【選択図】図7
