Abstract: A medical image processing device sets a boundary line, which indicates a boundary between a region of interest and a region of disinterest in a subject, in a still image of an endoscopic image, generates a boundary line display image in which the boundary line is displayed on the still image, and performs a control of displaying a video image of the endoscopic image and the boundary line display image on a display device. The boundary line to be displayed on the boundary line display image is displayed by being updated for each setting of the boundary line.

The boundary line to be displayed on the boundary line display image is displayed by being updated for each setting of the boundary line.

Abstract: First illumination light and second illumination light having different emission spectra are automatically switched so as to be emitted for a light emission period of at least one or more frames under specific light amount conditions, respectively. First image signals obtained in a case where an image is picked up using the first illumination light and second image signals obtained in a case where an image is picked up using the second illumination light are acquired. A first specific color signal for specific biological tissue among the first image signals and a second specific color signal for the specific biological tissue among the second image signals match.

Abstract: In a case where the detection target is detected, the detection target is associated with a landmark in a landmark setting process, and a detected position display indicator is displayed on a display. In a case where the detection target is not detected and the landmark is detected, a position information estimation process is executed, and an estimated position display indicator is displayed on the display.

Abstract: In a case where the detection target is detected, an actual position display control process of displaying a detected position display circle on a display in an actual position display mode (single line) is performed. In a case where the detection target is not detected, an estimated position display control process of displaying an estimated position display circle on the display in an estimated position display mode (double line) different from the actual position display mode is performed.

Abstract: An endoscope system includes an endoscope, which includes an instruction unit that issues a selection condition switching instruction and a still image storage instruction and which images a subject, and a processor. The processor acquires an endoscope image for each frame, temporarily stores the endoscope image selected based on a first selection condition or a second selection condition in a temporary storage area, performs image evaluation to assign an image evaluation value for each of the temporary storage images, and stores, based on the still image storage instruction, an optimal still image selected in accordance with the image evaluation value.

Abstract: A special observation image is obtained by performing an image pickup of an object to be observed illuminated with special light. Bs-image signals of the special observation image are assigned to brightness signals Y to generate a first observation image for display. Gs-image signals of the special observation image are assigned to brightness signals Y to generate a second observation image for display. The first observation image for display and the second observation image for display are automatically switched and displayed on a monitor.
