To provide a camera abnormality detection device and camera abnormality detection method which can correctly detect an abnormality of a camera attached to a movable body.SOLUTION: A camera abnormality detection device for detecting an abnormality of a camera attached to a movable body comprises: a positional deviation detection unit which detects a positional deviation of an imaging position of a first camera or second camera on the basis of the imaging position of an imaging object by the first camera acquired by an image acquisition unit or the imaging position of the imaging object by the second camera acquired by the image acquisition unit; a storage unit which chronologically stores determination information with which it is possible to determine whether the imaging state of the imaging object imaged by the first camera is in a first state or a second state on the basis of the photographed image acquired by the image acquisition unit; and an operation abnormality detection unit which detects that the photographed image of the first camera is not updated on the basis of the determination information stored in the storage unit.SELECTED DRAWING: Figure 1

    【課題】移動体に取り付けられたカメラの異常を正しく検出することができるカメラの異常検出装置およびカメラの異常検出方法を提供する。【解決手段】移動体に取り付けられたカメラの異常を検出するカメラの異常検出装置であって、画像取得部により取得された第1のカメラによる撮影対象の撮影位置、または画像取得部により取得された第2のカメラによる撮影対象の撮影位置に基づいて、第1のカメラまたは第2のカメラの撮影位置の位置ずれを検出する位置ずれ検出部と、画像取得部により取得された撮影画像に基づいて、第1のカメラにより撮影された撮影対象の撮影状態が第1の状態にあるか第2の状態にあるかを判別可能な判別情報を時系列的に記憶する記憶部と、記憶部に記憶された判別情報に基づいて、第1のカメラの撮影画像が更新されていないことを検出する動作異常検出部と、を備える。【選択図】 図1
