Abstract: An endoscope system has an insertion portion, a forward observation window configured to acquire a forward-field-of-view image, a lateral observation window configured to acquire a lateral-field-of-view image, an image pickup device and a video processor. A positional displacement correcting portion of the video processor detects a positional relationship between a portion where the forward-field-of-view image is formed and a portion where the lateral-field-of-view image is formed, on the image pickup device, and generates displacement amount data. A boundary correcting portion generates an image signal in which the forward-field-of-view image and the lateral-field-of-view image are arranged with an image center point provided in the portion and an image center point provided in the portion caused to correspond to each other, based on the displacement amount data.

Abstract: An endoscope image processing device includes an image acquisition section and a boundary region correction section. The image acquisition section 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 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.
