To record image data with its data volume appropriately reduced.SOLUTION: An on-vehicle drive recorder system includes; an imaging unit that images surroundings of an own vehicle; a recording unit that records an image captured by the imaging unit; a specific movement target acquisition unit that acquires a specific movement target 42 for which an amount of change in at least one of the size and the position of the movement target exceeds a predetermined threshold value; a cutting unit that cuts out a region 50A of the specific movement target in the captured image and acquires cutting position information for the region 50A of the specific movement target; and a recording control unit that acquires regions other than the cut region 50A of the specific movement target as a background image region 50B, and makes the recording unit record a composite image 60 obtained by combining the background image region 50B converted to a quality lower than that of the region 50A of the specific movement target and the cut region 50A of the specific movement target on the basis of the cutting position information.SELECTED DRAWING: Figure 6
【課題】データ量をより適切に低減した画像データを記録する。【解決手段】車載ドライブレコーダシステムは、自車両周辺を撮像する撮像部と、撮像部により撮像された撮像画像を記録する記録部と、移動物標の大きさ及び位置の少なくとも一方の変化量が所定の閾値を超える特定移動物標42を取得する特定移動物標取得部と、撮像画像中の特定移動物標の領域50Aを切り出すと共に特定移動物標の領域50Aの切出位置情報を取得する切出部と、切り出された特定移動物標の領域50A以外の領域を背景画像領域50Bとして取得し、特定移動物標の領域50Aよりも低画質に変換した背景画像領域50Bと切り出された特定移動物標の領域50Aとを切出位置情報に基づいて合成した合成画像60を記録部に記録させる記録制御部と、を含む。【選択図】図6
