Abstract: A medical image processing device a reference image that is a medical image with which boundary line information related to a boundary line that is a boundary between an abnormal region and a normal region and landmark information related to a landmark that is a characteristic structure of the subject are associated and a captured image that is the medical image captured in real time, detects the landmark from the captured image, calculates a ratio of match between the landmark included in the reference image and the landmark included in the captured image, estimates a correspondence relationship between the reference image and the captured image on the basis of the ratio of match and information regarding the landmarks included in the reference image and the captured image, and generates a superimposition image in which the boundary line associated with the reference image is superimposed on the captured image on the basis of the correspondence relationship.

Abstract: In a mono-light emission mode, specific illumination light is emitted and a specific observation image obtained from the image pickup of an object to be observed illuminated with the specific illumination light is displayed on a monitor 18. In a multi-light emission mode, first illumination light and second illumination light are emitted while being switched according to a specific light emission pattern and a first observation image and a second observation image are displayed on the monitor 18 while being switched according to a specific display pattern. In a case where a designated condition set in advance by a user is satisfied, a mode is automatically switched to the mono-light emission mode from the multi-light emission mode.

Abstract: A vessel suppression process is performed on RGB image data. A display of capillary vessels is suppressed by the vessel suppression process. After the vessel suppression process, tone of the RGB image data is reversed. Thereby, a suppressed-and-reversed image is produced. Even after the tone reversal, the capillary vessels do not interfere with observation of a ductal structure in the suppressed-and-reversed image, because the display of the capillary vessels is suppressed. In the suppressed-and-reversed image, the ductal structure is darker than a mucous membrane due to the tone reversal, so that the color of the ductal structure is close to that of an indigo.
Abstract translation: 对RGB图像数据进行容器抑制处理。 通过血管抑制过程抑制毛细血管的显示。 在容器抑制处理之后，RGB图像数据的色调被反转。 由此，产生抑制和反转的图像。 即使在色调反转之后，由于毛细血管的显示被抑制，所以毛细血管在抑制和反转的图像中不妨碍观察导管结构。 在抑制和反转的图像中，由于色调反转，导管结构比粘膜更暗，使得导管结构的颜色接近于靛蓝的颜色。

Abstract: A first illumination light beam is switched to a second illumination light beam and the second illumination light beam is emitted for a period of at least one frame, during a period in which the first illumination light beam is emitted. A first image or a second image obtained by imaging an observation target illuminated with the first illumination light beam or the second illumination light beam is acquired for each frame. At least one first image and at least one second image that satisfy a preset selection condition are selected and stored from a plurality of the first images and a plurality of the second images acquired in a preset period prior to a time of a processing start operation of image storage processing.

Abstract: First illumination light having a first peak wavelength range and second illumination light having a second peak wavelength range different from the first peak wavelength range are automatically switched and emitted. Identification processing for allowing a first object to be observed and a second object to be observed to be identified in a composite display image is performed. The first object to be observed has a first absorption peak in the first peak wavelength range of the first illumination light and the second object to be observed has a second absorption peak in the second peak wavelength range of the second illumination light.

Abstract: An image processing unit includes a shake amount calculation section and a static image-storage control section, and the shake amount calculation section includes a shake amount-calculation processing section and an algorithm switching section. The algorithm switching section applies an algorithm varying for each image, and selects images of which the shake amounts calculated by the shake amount-calculation processing section are small. A first image and a second image, which are selected as the images of which the shake amounts are small, are stored in a static image-storage unit. A display control unit displays static images for storage.

Abstract: Provided are an endoscope system and a method of operating the same capable of assisting in capturing an image defined by guidelines. In order to obtain a reference-equivalent image equivalent to a predetermined reference image for each examination region, an examination image is acquired by imaging an examination region. An at-examination imaging condition acquisition unit acquires an at-examination imaging condition obtained at an acquisition timing of an examination image. A still image saving request signal output unit outputs a still image saving request signal for requesting saving of a still image of the examination image in a case where an at-examination imaging condition satisfies a reference imaging condition for obtaining a predetermined reference image for each examination region.

Abstract: An endoscope system includes: an endoscope including a side-viewing observation unit that includes a field of view in a lateral direction of an insertion part to be inserted into an object to be observed and a second protruding portion that protrudes from the insertion part and forms a blind spot in the field of view of the side-viewing observation unit; an image acquisition unit that acquires a side-viewing observation image by using the side-viewing observation unit; a monitor that displays the side-viewing observation image; and a display control section that allows at least a part of the blind spot of the side-viewing observation image in which the second protruding portion is shown up not to be displayed, and displays the side-viewing observation image on the monitor.
