To provide a technique which can suppress false detection of abnormalities of a camera equipped in a mobile body.SOLUTION: The abnormal detector for detecting abnormalities of a camera equipped in a mobile body includes: a determination unit for performing determination processing for determining the presence or absence of abnormalities in the camera on the basis of changes with time in the position of a feature point extracted from a frame image taken by the camera; and an AGC control unit for performing a control to suppress the width of change in the gain in the AGC (Automatic Gain Control) circuit of the camera when performing the determination processing.SELECTED DRAWING: Figure 1

    【課題】移動体に搭載されるカメラの異常を誤検出することを抑制できる技術を提供する。【解決手段】移動体に搭載されるカメラの異常を検出する異常検出装置は、前記カメラの異常の有無を、前記カメラで撮影されたフレーム画像から抽出される特徴点の位置の時間変化に基づき判定する判定処理を行う判定部と、前記判定処理を行う際に前記カメラのAGC(Automatic Gain Control)回路におけるゲインの変化幅を抑制する制御を行うAGC制御部と、を備える。【選択図】図1
