Endoscopic examination support apparatus, endoscopic examination support method, and recording medium

An endoscopic examination support method comprising:

• detecting a lesion candidate from an endoscopic image acquired by imaging an interior of a luminal organ;
• setting, as a flag according to a position in the interior of the luminal organ at which the endoscopic image including the lesion candidate is acquired, a first flag and a second flag, the first flag being set in a period from a time when pull-out of the endoscope camera inserted into the interior of the luminal organ in order to acquire the endoscopic image is started to a time when the endoscope camera passes through a predetermined site in the luminal organ, the second flag being set in a period from a time when the endoscope camera passes through the predetermined site to a time when pull-out of the endoscope camera is completed;
• determining a risk of the lesion candidate based on at least a size of the lesion candidate and the flag;
• generating a display image including information relating to a position of the lesion candidate in the endoscopic image, information relating to a position in the interior of the luminal organ corresponding to the flag, and information relating to the risk of the lesion candidate, and a detection frame which surrounds the lesion candidate present in the endoscopic image and is displayed in different manners according to the flag and the risk of the lesion candidate;
• and
• outputting the display image.

A non-transitory computer-readable recording medium storing a program, the program causing a computer to execute:

• detecting a lesion candidate from an endoscopic image acquired by imaging an interior of a luminal organ;
• setting, as a flag according to a position in the interior of the luminal organ at which the endoscopic image including the lesion candidate is acquired, a first flag and a second flag, the first flag being set in a period from a time when pull-out of the endoscope camera inserted into the interior of the luminal organ in order to acquire the endoscopic image is started to a time when the endoscope camera passes through a predetermined site in the luminal organ, the second flag being set in a period from a time when the endoscope camera passes through the predetermined site to a time when pull-out of the endoscope camera is completed;
• determining a risk of the lesion candidate based on at least a size of the lesion candidate and the flag;
• generating a display image including information relating to a position of the lesion candidate in the endoscopic image, information relating to a position in the interior of the luminal organ corresponding to the flag, and information relating to the risk of the lesion candidate, and a detection frame which surrounds the lesion candidate present in the endoscopic image and is displayed in different manners according to the flag and the risk of the lesion candidate;
• and
• outputting the display image.
