1. An information processing apparatus, comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to perform operations comprising:
detecting an abnormal region, which is an image region inferred to represent an abnormal portion inside a body, in each of a plurality of video frames constituting a video in which the inside of the body is captured;
analyzing the plurality of video frames to determine a proportion of a number of video frames in which the abnormal region is detected;
starting outputting of output information related to the detected abnormal region when a score based on the proportion becomes equal to or more than a first threshold value in a state where outputting of the output information is not being performed; and
ending outputting of the output information when the score becomes equal to or less than a second threshold value in a state where outputting of the output information is being performed,
wherein the second threshold value is smaller than the first threshold value.
