Abstract:
A hole portion detection unit detects a hole portion of the bronchus from at least one of a first endoscope image or a second endoscope image temporally earlier than the first endoscope image. A first parameter calculation unit calculates a first parameter indicating the amount of parallel movement for matching the hole portions of the two endoscope images with each other. A second parameter calculation unit performs alignment between the two endoscope images based on the first parameter, and calculates a second parameter including the amount of enlargement and reduction. Based on the two parameters, a movement amount calculation unit calculates the amount of movement of the endoscope from the acquisition time of the second endoscope image to the acquisition time of the first endoscope image.

Claim (Index 7):
An endoscope position specifying method, comprising:\n sequentially acquiring endoscope images that are generated by an endoscope inserted into a tubular structure having a plurality of branch structures and that show an inner wall of the tubular structure; detecting a hole portion of the tubular structure from at least one of a first endoscope image or a second endoscope image, which is acquired temporally before the first endoscope image, among the sequentially acquired endoscope images; calculating a first parameter indicating an amount of parallel movement of the first endoscope image with respect to the second endoscope image in order to match hole portions of the first and second endoscope images with each other; performing alignment between the first and second endoscope images based on the first parameter and calculating a second parameter including an amount of enlargement and reduction of the first endoscope image with respect to the second endoscope image in order to match the hole portions of the first and second endoscope images after the alignment with each other; and calculating an amount of movement of the endoscope from an acquisition time of the second endoscope image to an acquisition time of the first endoscope image based on the first and second parameters.
