ENDOSCOPE SYSTEM AND METHOD FOR OPERATING SAME
FIG15 is a diagram illustrating a display screen that displays lumen portion information as position information of ROIs  FIG16 is a diagram illustrating a display screen that displays distance information indicating the distance from a reference structure as position information of ROIs
FIG15 illustrates a specific example in which, in a case where the ROI R1 and the ROI R2 have been detected, the lumen portion information of the lumen portion in which the ROI R1 has been detected and the lumen portion information of the lumen portion in which the ROI R2 has been detected are displayed on the display screen of the display unit 18. In this example, the names of the lumen portions are displayed in text as the lumen portion information, and it is indicated that the ROI R1 has been detected in the descending colon and that the ROI R2 has been detected in the transverse colon. In FIG15, a schematic diagram 94 of a lumen is displayed. The schematic diagram 94 is divided into six sections corresponding to the cecum, the ascending colon, the transverse colon, the descending colon, the sigmoid colon, and the rectum. In the schematic diagram 94, the section corresponding to the descending colon and the section corresponding to the transverse colon are displayed differently from the other sections. Furthermore, in FIG15, the difference between the section corresponding to the descending colon and the section corresponding to the transverse colon is represented by the difference in intervals of hatching. In this example, the schematic diagram 94 is also displayed on the display screen of the display unit 18, but the method for displaying the lumen portion information is not limited thereto. The display mode of the section in which a ROI has been detected may be changed in accordance with a discrimination result.  FIG16 illustrates a specific example in which, in a case where the ROI R1 and the ROI R2 have been detected, the position of the ROI R1 is displayed as the distance from the anus and the position of the ROI R2 is displayed as the distance from the Bauhin's valve, on the display screen of the display unit 18. In FIG16, the distance information is displayed in the form of text and numerical values, that is, "A cm from the anus" is displayed for the ROI R1 and "B cm from the Bauhin's valve" is displayed for the ROI R2. In FIG16, the distance information is displayed in the form of text and numerical values and also a schematic diagram 96 of the lumen is displayed, but the method for displaying distance information indicating the distance from the reference structure is not limited thereto.

['1. An endoscope system comprising: an endoscope; an endoscopic image acquisition unit that acquires an endoscopic image acquired by capturing an image of a lumen with the endoscope; a region-of-interest detecting unit that detects a region of interest in the lumen by using the endoscopic image; a position information acquisition unit that acquires position information of the region of interest; and a display unit that displays the position information of the region of interest.', '2. The endoscope system according to claim 1, comprising: a first marked image generating unit that generates a first marked image having a marking at a position corresponding to the position information of the region of interest in a schematic diagram of the lumen, wherein the display unit displays the first marked image.']
