To allow for recording important images with high quality as well as a long-time data recording in a situation where recordable data capacity is limited.SOLUTION: When operating in a continuous recording mode, control is performed so as to improve the quality of recorded images only for a certain period of time by detecting a specific event generating no trigger signal. Length of the certain period of time is automatically switched according to the type of a detected event. When important images are highly likely to be generated in such cases as a host vehicle turning left around an intersection, a person being detected in backward traveling, a lane deviation alarm being raised, and sudden deceleration, insufficient inter-vehicle distance, steep turn being detected, image data is recorded in a state where the quality is improved by a necessary time length. The quality is improved by such a way as changing a frame rate of the images to be recorded. By optimizing a time zone for improving quality for each event, long-time data recording can be realized, and important images can be recorded with high quality.SELECTED DRAWING: Figure 2

    【課題】記録可能なデータ容量が限られている状況において、重要な映像を高品質で記録すると共に、長時間のデータ記録を可能にすること。【解決手段】常時記録モードで動作する場合に、トリガ信号が発生しない特定事象の検知により一定時間だけ、記録する映像の品質を上げるように制御する。一定時間の長さは、検知した事象の種類に応じて自動的に切り替える。自車両が交差点付近で左折する場合、バック走行で人を検知した場合、車線逸脱の警報が発生した場合、急減速、車間距離不足、急旋回を検知した場合のように重要な映像が発生する可能性が高い時に、必要な時間長だけ品質を向上させた状態で画像データを記録する。記録する画像のフレームレートの変更などにより品質を向上させる。品質を上げる時間帯を事象毎に最適化することにより、長時間のデータ記録を実現し、しかも重要な画像を高品質で記録できる。【選択図】図2
