摘要： The image processing device 1X includes an acquisition means 30X, a variation detection means 311X, a selection means 312X, and a lesion detection means 34X. The acquisition means 30X acquires an endoscopic image obtained by photographing an examination target by a photographing unit provided in an endoscope. The variation detection means 311X detects a degree of variation between the endoscopic images. The selection means 312X selects either one of a first model or a second model based on the degree of variation, the first model making an inference regarding a lesion of the examination target based on a predetermined number of the endoscopic images, the second model making an inference regarding the lesion based on a variable number of the endoscopic images. The lesion detection means 34X detects the lesion based on a selection model that is either the first model or the second model selected.

摘要： An information processing apparatus (2000) detects an abnormal region (30) from a predetermined range (16) of a video frame (14). The information processing apparatus (2000) determines whether a predetermined condition is satisfied in a case where the abnormal region (30) is detected from the predetermined range (16) of a certain video frame (14) and the abnormal region (30) is not detected from the predetermined range (16) of a predetermined video frame (14) generated later than the video frame (14). In a case where the predetermined condition is not satisfied, the information processing apparatus (2000) performs a predetermined notification.

摘要： The image processing device 1X includes an acquisition means 30X, a detection means 31X, a first determination means 32X, and a second determination means 33X. The acquisition means 30X acquires an endoscopic image of an examination target. The detection means 31X detects, based on the endoscopic image, a lesion region which is a candidate lesion region of the examination target in the endoscopic image. The first determination means 32X determines whether or not the endoscopic image is an image adequate to determine a degree of progression or an invasion depth, based on a size of the lesion region and/or a degree of reliability regarding a probability of the lesion region as the lesion. The second determination means 33X determines the degree of progression or the invasion depth, based on the endoscopic image determined to be the image adequate to determine the degree of progression or the invasion depth.

摘要： The image processing device 1X includes a classification means 31X, an image selection means 33X, and a region extraction means 34X. The classification means 31X classifies each captured image acquired in time series by photographing an inspection target by a photographing unit provided in an endoscope, according to whether or not the each captured image includes an attention part to be paid attention to. The image selection means 33X selects a target image to be subjected to extraction of a region of the attention part from the each captured image, based on a result of the classification. The region extraction means 34X extracts the area of the attention part from the target image.
