Image processing device, image processing method, and storage medium

An image processing method executed by a computer, the image processing method comprising:

• acquiring a captured image obtained by photographing an examination target by a photographing unit provided in an endoscope;
• calculating, based on the captured images in time series obtained from a start time, a score regarding a likelihood of a presence of a region of interest in the captured images;
• upon detecting a variation in the captured images, setting a time after the variation as the start time;
• and
• classifying, based on the score, the captured images in time series if a predetermined condition is satisfied.

A non-transitory computer readable storage medium storing a program executed by a computer, the program causing the computer to:

• acquire a captured image obtained by photographing an examination target by a photographing unit provided in an endoscope;
• calculate, based on the captured images in time series obtained from a start time, a score regarding a likelihood of a presence of a region of interest in the captured images;
• upon detecting a variation in the captured images, set a time after the variation as the start time;
• and
• classify, based on the score, the captured images in time series if a predetermined condition is satisfied.
