Abstract:
1. A fluorescent imaging device comprising: an irradiation section that irradiates an object to be examined with excitation light and reference light; an image pickup section that picks up a fluorescence image based on the excitation light and a reflected light image including a first reflected light image of at least a predetermined wavelength region based on the reference light; an image signal generating section that generates a plurality of image signals making up a diagnostic fluorescent image including an image signal of a fluorescent image corresponding to the fluorescence image, an image signal of the reflected light image including a first reflected light image corresponding to the first reflected light image from the reflected light image; a comparison section that compares intensity of the image signal of the fluorescent image and that of the image signal of the reflected light image including the first reflected light image multiplied by a predetermined value, or compares a value obtained by calculating relative intensity between the fluorescent image and the first reflected light image based on the image signal of the fluorescent image and the image signal of the reflected light image including the first reflected light image, with a predetermined threshold; and a selection section that selectively outputs one of the image signal of the reflected light image including the first reflected light image and the image signal of the fluorescent image based on the comparison result by the comparison section as one image signal making up the diagnostic fluorescent image.
