  • Publication number: 20250000329
    Abstract: The image acquisition means acquires a captured image by an endoscope. The position acquisition means acquires positional information of the endoscope. The lesion detection means detects a lesion from the captured image. The washing degree determination means determines a degree of intestinal tract washing from the captured image. The reaching determination means determines that the endoscope reaches a cecum from the captured image. The end determination means determines an end timing of an examination by the endoscope. The calculation means calculates an observation time based on a timing that the endoscope reaches the cecum and the end timing.
