ENDOSCOPE SYSTEM AND METHOD FOR OPERATING SAME
FIG17 is a diagram illustrating a display screen that displays insertion lengths as position information of ROIs  FIG18 is a block diagram illustrating the functions of a ROI searching image processing unit having a biological feature value calculating unit
FIG17 illustrates a specific example in which, in a case where the ROI R1 and the ROI R2 have been detected, the insertion length with which the ROI R1 has been detected and the insertion length with which the ROI R2 has been detected are displayed on the display screen of the display unit 18. In this example, the insertion lengths are displayed in the form of numerical values, that is, the insertion length with which the ROI R1 has been detected is X cm and the insertion length with which the ROI R2 has been detected is Y cm. In FIG17, the insertion lengths are displayed in the form of numerical values and also a schematic diagram 98 of the lumen is displayed, but the method for displaying the insertion lengths is not limited thereto.  In this case, the ROI searching image processing unit 66 is replaced with a ROI searching image processing unit 100, as illustrated in FIG18. The ROI searching image processing unit 100 has a biological feature value calculating unit 102 in addition to the components of the ROI searching image processing unit 66. A description will not be given of the same components as those of the ROI searching image processing unit 66.

['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.', '8. The endoscope system according to any one of claims 5 to 7, comprising: a discrimination result storage unit that stores the discrimination result.', '10. The endoscope system according to claim 4 or 9, comprising: a warning unit that provides a warning, based on the position information of the region of interest and the insertion state of the endoscope.', '12. The endoscope system according to any one of claims 4 to 11, comprising: a biological feature value calculating unit that calculates a biological feature value of the region of interest, wherein the display unit changes a display mode of the marking by using the biological feature value in addition to a discrimination result acquired by the discrimination unit.']
