Abstract: An image processing device includes a storage section, an estimation calculation section, and an image output section. A pixel is sequentially shifted so that overlap occurs to acquire a light-receiving value of the pixel as a low-resolution frame image. The storage section stores the low-resolution frame image. The estimation calculation section estimates estimated pixel values at a pixel pitch smaller than the pixel pitch of the low-resolution frame image. The image output section outputs a high-resolution frame image that has a resolution higher than that of the low-resolution frame image based on the estimated pixel values. The estimation calculation section calculates the difference between the light-receiving value of the pixel set at a first position and the light-receiving value of the pixel set at a second position, and estimates the estimated pixel values based on the difference.

Abstract: Provided is a fluoroscopy apparatus comprising a white-light-image generating section that generates a white-light image of observation target, a fluorescence-image generating section that generates a fluorescence image of the observation target, a fluorescence-image correcting section that normalizes the fluorescence image with the white-light image, a displacement calculating section that calculates the displacement of the observation target from a plurality of white-light images generated at time intervals, a region-size calculating section that calculates the size of a region having a fluorescence intensity higher than or equal to a predetermined threshold value from the fluorescence image, and a control unit that controls the fluorescence-image correcting section so that, when the displacement of the observation target relative to the size of the region is larger than or equal to a predetermined proportion, normalization of the fluorescence image is stopped.

Abstract: A fluoroscopy device includes a light source that irradiates an observation site with excitation light and white light; a fluorescence-image generating section that acquires a fluorescence image by capturing fluorescence generated in the observation site irradiated with the excitation light; a reference-image generating section that acquires a reference image by capturing return light returning from the observation site irradiated with the white light; an observation-condition determining section that determines the observation conditions of the observation site on the basis of the reference image acquired by the reference-image generating section; a preprocessing section that corrects gradation values of the reference image on the basis of the observation conditions of the observation site; and a fluorescence-image correcting section that generates a corrected fluorescence image by dividing the fluorescence image acquired by the fluorescence-image generating section by the reference image whose gradation val

Abstract: A medical manipulator system in which an operator controls operation of a device near a patient, the medical manipulator system includes a single or a plurality of manipulators, a control unit, and a forcible shutdown instruction unit. The single or a plurality of manipulators are disposed near the patient and configured to hold a medical tool. The control unit is configured to control operation of the manipulator. The forcible shutdown instruction unit is disposed near the patient and configured to instruct the control unit to forcibly shut down operation of the manipulator.
