SURVEILLANCE AND VIDEO RECORDING APPARATUS AND RECORDED VIDEO MONITORING PROGRAM

To readily achieve accuracy abnormality detection.SOLUTION: A surveillance and video recording apparatus 1 comprises an imaging unit 10 that photographs both a surveillance recording target and a light emitter, which indicates a status of the surveillance recording target by at least one of lit, blink, and unlit, in the same screen, a light-emitter area detection unit 13a that detects an area displayed with the light emitter in the image photographed by the imaging unit as a light-emitter area, a first variation determination unit 13b that determines at least one of the lit, the blink, and the unlit based on brightness change in the light-emitter area, a recording function unit 13c that initiates recording the image photographed by the imaging unit based on the determination result by the first variation determination unit, and a past brightness information holding unit 13d that retains past brightness information, which represents the brightness information of the light-emitter area from the current photographing timing to the time a prescribed period before the present photographing timing at the imaging unit.SELECTED DRAWING: Figure 2 【課題】高精度の異常検出を容易に実現する。【解決手段】監視録画装置１は、監視録画対象と、監視録画対象の状態を点灯、点滅又は消灯のうち少なくとも何れか一つで示す発光体との両方を一画面内に撮影する撮影部１０と、撮影部により撮影された画像中において発光体が映っている領域を発光体領域として検出する発光体領域検出部１３ａと、発光体領域の明度変化により発光体の点灯、点滅又は消灯のうち少なくとも何れか一つの変化を判定する第１変化判定部１３ｂと、第１変化判定部の判定結果に基づいて撮影部により撮影された画像の録画を開始する録画機能部１３ｃと、撮影部における現在の撮影タイミングから事前に設定された所定期間遡った過去の撮影タイミングまでの発光体領域の明度情報を示す過去明度情報を保持する過去明度情報保持部１３ｄと、を備える。【選択図】図２
