Image processing device, image processing method, and storage medium

An image processing method comprising:

• creating a three-dimensional model of a subject from a group of images captured by an endoscope;
• detecting a non-observed region in which an image from the group of images is not captured by the endoscope based on the three-dimensional model;
• acquiring operation signals of an endoscope system including the endoscope;
• determining whether the operation signal matches a condition, wherein the condition includes an operation of the endoscope system that causes the group of images has a missing portion;
• responsive to determining the operation signal matches the condition, temporarily stopping detection of the non-observed region.

A computer-readable, non-transitory storage medium configured to cause a computer to execute:

• creation of a three-dimensional model of a subject from a group of images captured by an endoscope;
• detection of a non-observed region in which an image from the group of images is not captured by the endoscope based on the three-dimensional model;
• acquisition of operation signals of an endoscope system including the endoscope;
• and
• determination of whether the operation signal matches a condition, wherein the condition includes an operation of the endoscope system that causes the group of images has a missing portion;
• responsive to determining the operation signal matches the condition, temporary stopping the detection of the non-observed region.
