Abstract: Provided is a fluorescence observation device comprising an illuminating section that emits excitation light and illumination light onto a subject; a fluorescence-image capturing section that acquires a fluorescence image by image-capturing fluorescence generated in the subject by irradiation with the excitation light from the illuminating section; a return-light-image capturing section that acquires a return-light image by image-capturing return light that returns from the subject by irradiation with the illumination light from the illuminating section; a region extracting section that extracts a high-luminance region in which the fluorescence image acquired by the fluorescence-image capturing section has a gradation level higher than or equal to a set threshold value; and a threshold setting section that sets the threshold value higher as the gradation level of the return-light image acquired by the return-light-image capturing section increases.

Abstract: Provided is a fluoroscopy system includes a light source device that emits white light and excitation light for irradiation of a subject; a white-light-image generating section that generates a white-light image by capturing the white light reflected from the subject; a fluorescence-image generating section that generates a fluorescence image by capturing fluorescence from the subject irradiated with the excitation light; an intensity-distribution generating section that generates a fluorescence intensity distribution of pixels of the fluorescence image; a peak-detecting section that detects a fluorescence-intensity peak in the fluorescence intensity distribution; a peak-count comparing section that calculates a count of the peak; an image-combining section that generates a combined image by superimposing a display representing a region including a pixel having the fluorescence intensity at the peak on the white-light image or the fluorescence image based on the peak count; and a monitor that displays the com

Abstract: To provide an endoscope apparatus with which an affected site can be treated with a treatment instrument while viewing tissue in the body cavity, including a region located at the rear of the treatment instrument. An endoscope apparatus is employed, which is provided with an image generating portion that generates an image of an subject; an image-saving memory portion that saves a real-time image; a forceps-region extracting portion that extracts a forceps region, in which forceps exist, from the real-time image; an image-position aligning portion that aligns positions of the saved image saved in the image-saving memory portion and the real-time image; a forceps-region extracting portion that extracts a region corresponding to the forceps region from the saved image saved in the image-saving memory portion; and an image combining portion that combines an image of the region extracted by the forceps-region extracting portion and the real-time image.
