Abnormality detection program, abnormality detection device, and abnormality detection method

The program causes the abnormality detection device (100) to function as: an acquisition unit (11) that acquires continuous image data indicating continuously captured images; a parameter determination unit (12) that determines, on the basis of the continuous image data, a parameter for dividing the continuous image data in the width direction and/or the height direction of the image and in the time direction; a feature amount calculation unit (14) that calculates a feature amount from each of fragment data obtained by dividing the continuous image data using the parameters determined by the parameter determination unit (12); and a detection unit (15) that detects an abnormality pertaining to the subject of the captured image on the basis of a comparison between the feature amount calculated by the feature amount calculation unit (14) and a reference value. 程序使异常检测装置(100)作为如下单元起作用：取得部(11)，其取得表示连续拍摄到的图像的连续图像数据；参数决定部(12)，其基于连续图像数据，决定用于将连续图像数据在图像的宽度方向及高度方向中的至少一者以及时间方向上进行分割的参数；特征量计算部(14)，其从使用由参数决定部(12)决定的参数将连续图像数
