Abstract: A region of interest located in a first part to be observed is detected from a medical image at a first timing. In a case where a tip portion of an endoscope moves from the first part to be observed toward a second part to be observed and then moves to the first part to be observed again, a return determination unit performs first determination processing for determining whether the tip portion has returned to the first part to be observed, by using a medical image acquired a second timing. A display control unit performs display control of a monitor by using a determination result of the return determination unit.

Abstract: A processor device includes an image signal acquiring unit, an image processing unit, and a display control unit. The image signal acquiring unit acquires a digital image signal corresponding to an observation mode from an endoscope. The image processing unit includes a region-of-interest-detection-mode image processing unit. The region-of-interest-detection-mode image processing unit detects a region of interest from an endoscopic image and outputs a detection result of the region of interest and a cumulative detection time period of the region of interest.

Abstract: An endoscope apparatus includes: a lesion information acquisition unit that acquires acquired lesion information; a lesion identification unit that compares existing lesion information with the acquired lesion information and determines whether the acquired lesion information corresponds to the same lesion indicated by the existing lesion information; a lesion count unit that counts a lesion count, which is the number of lesions detected in a single endoscopic examination; a display unit; and a control unit that increments the lesion count counted by the lesion count unit by one when the lesion identification unit determines that the acquired lesion information does not correspond to the same lesion indicated by the existing lesion information.

Abstract: There are provided an endoscopic image processing device, an endoscopic image processing method, an endoscopic image processing program, and an endoscope system that appropriately notify region-of-interest information about a region of interest included in an endoscopic image according to an endoscope operator's action.
An endoscope operator's action on a portion to be observed of an endoscopic image is recognized from endoscopic images, and first emphasis display where region-of-interest information is displayed in the endoscopic image at a first emphasis level and second emphasis display where the region-of-interest information is displayed at a second emphasis level relatively lower than the first emphasis level are switched according to a recognition result.

Abstract: Provided are a medical image processing apparatus, a medical image processing method, a program, and a diagnosis support apparatus that report a region of interest without hindering observation of the boundary between the region of interest and a region of non-interest in a medical image. A medical image processing apparatus includes a superimposition processing unit that superimposes, on a medical image, a figure for reporting a region of interest included in the medical image. The superimposition processing unit superimposes the figure on an inside of the region of interest such that at least part of a boundary between the region of interest and a region of non-interest is not superimposed with the figure, thereby reporting the region of interest without hindering observation of the boundary between the region of interest and the region of non-interest.
