An endoscope image processing device includes an image acquisition section (305) and a boundary region correction section (315). The image acquisition section (305) acquires image signals that form a front image corresponding to a front field of view and a side image corresponding to a side field of view as a single acquired image. A region within the acquired image that corresponds to the front field of view is referred to as a front region, and a region within the acquired image that corresponds to the side field of view is referred to as a side region. The boundary area correction section (315) performs a process that causes at least one of an image of the front region and an image of the side region to overlap a boundary region that is a region that defines a boundary between the front region and the side region.
