Abstract: An information processing apparatus (2000) detects an abnormal region (30) in each of a plurality of video frames (14) constituting video data (12) in which the inside of a body is captured. The information processing apparatus (2000) outputs output information related to the detected abnormal region (30). Herein, the information processing apparatus (2000) starts outputting of the output information when a detection score based on a proportion of the number of the video frames (14) in which the abnormal region (30) is detected becomes equal to or more than a first threshold value in a state where outputting of the output information is not being performed. Further, the information processing apparatus (2000) ends outputting of the output information when the detection score becomes equal to or less than a second threshold value in a state where outputting of the output information is being performed.

Abstract: Provided are an information processing device, a display method, and a program that allow to easily grasp during examination that a lesion is captured how long before from now which is detected by detection processing for an image captured by an endoscope.
An information processing device (1) includes: an image acquisition unit (2) configured to sequentially acquire a current image captured by an endoscope; a lesion detection unit (3) configured to sequentially perform detection processing of a lesion site on the images sequentially acquired by the image acquisition unit (2); and a display control unit (4) configured to display, on a display device, a degree of lapse of time up to a current time from a capturing time of the image in which the lesion site is detected by the lesion detection unit (3).
