Patent ID: 8854444

Claim:
An information processing apparatus that performs an image process on data of a group of in-vivo images which are obtained from a capsule endoscope that captures in-vivo images of a subject via a receiver that performs a wireless communication with the capsule endoscope and sorted in an imaging time sequence, comprising: a storage unit that stores the data of the in-vivo images and information which is associated with the data of the in-vivo images and related to a position of the capsule endoscope in an inside of the subject; a positional information obtaining unit that obtains positional information of the capsule endoscope in capturing the in-vivo images based on the information related to the position, the positional information including a positional coordinate of the capsule endoscope; a sequence changing unit that changes a sorting sequence of the in-vivo images along a route from an upper to a lower stream in the digestive canal based on the positional information obtained by the positional information obtaining unit; and a correlation degree calculator that calculates a degree of correlation between predetermined in-vivo images based on the data of the in-vivo images, wherein the sequence changing unit that changes the sorting sequence of the in-vivo images based on the positional information obtained by the positional information obtaining unit and the degree of correlation calculated by the correlation degree calculator; and when a position coordinate of an already-checked second in-vivo image is present within a predetermined range of a position coordinate of a first in-vivo image as a check target and a degree of correlation between the first in-vivo image and the second in-vivo image is higher than a criterion, the sequence changing unit changes the sorting sequence of the first and the second in-vivo images and a third in-vivo image sorted one of right before and right after the second in-vivo image.
