ENDOSCOPE SYSTEM AND METHOD FOR OPERATING SAME
FIG13 is a diagram illustrating a display screen of a display unit that displays the first marked image  FIG14 is a diagram illustrating the display screen in which a warning indication has been changed in accordance with a discrimination result
For example, as illustrated in FIG13, the first marked image 90 is displayed on the display screen of the display unit 18. In FIG13, the endoscopic image 86 is displayed in addition to the first marked image 90. In the first marked image 90, the mark M1 indicating that the ROI R1 has been detected and the mark M2 indicating that the ROI R2 has been detected are displayed. Accordingly, the user is able to easily recognize the positions of the ROIs, and thus the diagnosis time taken to re-search for the ROIs R1 and R2 is further shortened. In the first marked image 90, the insertion state L of the endoscope 12 is displayed at the corresponding position in the schematic diagram 92. In FIG13, the end of the insertion state L of the endoscope 12 is at the position of the mark M1. That is, it is indicated that the distal end portion 21 of the endoscope 12 in the lumen is at the detection position P1 at which the ROI R1 has been detected. Accordingly, the user is able to recognize the current insertion state of the endoscope 12, and is thus able to move the distal end portion 21 of the endoscope 12 to a desired position in a short time. As a result, the diagnosis time is further shortened. The mark M1 and the mark M2 are displayed in different manners in accordance with a discrimination result acquired by the discrimination unit 82. In FIG13, the line of the mark M2 is thicker than the line of the mark M1. This enables the user to easily recognize the discrimination result. On the display screen of the display unit 18, a warning indication 95 indicating that the distal end portion 21 is close to the ROI is displayed (see FIG13). Accordingly, the ROI is prevented from being overlooked. The display mode of the warning indication 95 is changed in accordance with a discrimination result acquired by the discrimination unit 82. In FIG13, "!" is displayed as the warning indication 95 in a case where a discrimination result indicating an adenoma is acquired by the discrimination unit 82.  On the other hand, in a case where the end of the insertion state L of the endoscope 12 is at the position of the mark M2 as illustrated in FIG14, that is, in a case where the distal end portion 21 of the endoscope 12 in the lumen is at the detection position P2 at which the ROI R2 has been detected, the warning indication 95 is changed to "!!". Because the ROI R2 is a region for which a discrimination result indicating a lesion portion is acquired by the discrimination unit 82, it is preferable to display the warning indication 95 that is further emphasized. This enables the user to recognize that the lesion needs a particular care, which makes it possible to more reliably prevent the ROI requiring a detailed examination or treatment from being overlooked.

['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.']
