Abstract
An image processing device for processing time-series intraluminal images captured by an imaging device moving in an in-vivo lumen. The image processing device includes a structural area extracting unit that extracts a structural area from the intraluminal image; a corresponding area extracting unit that extracts a corresponding area corresponding to the structural area from the intraluminal image at a second time point different from a first time point at which the structural area is extracted; a lumen deep portion extracting unit that extracts a lumen deep portion, on which a deep portion in the lumen is captured, from the intraluminal image; and a movement amount estimating unit that estimates a movement amount of the imaging device based on positions of the structural area, the corresponding area and the lumen deep portion.
