FLUORESCENT OBSERVATION DEVICE AND FLUORESCENT OBSERVATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To enable reliably notifying a user of the presence of a fluorescent area in an observation visual field irrespective to differences of observation conditions.SOLUTION: A fluorescent observation device 1 comprises: a light source 3 for irradiating an observation object X with reference light and excitation light; a fluorescent image generation part 62 for generating a fluorescent image G2 by imaging fluorescence generated in the observation object X by irradiation of the excitation light; a reference image generation part 61 for generating a reference image G1 by imaging return light that is returned from the observation object X by irradiation of the reference light; an image composition part 65 for generating a composite image G by superposing the fluorescent image G2 generated by the fluorescent image generation part 62 on the reference image G1 generated by the reference image generation part 61; a determination part 63 for comparing a luminance value in each position in the reference image G1 to a predetermined threshold and determining the presence and absence of a position in which a luminance value is equal to or less than the threshold; and a notification part 65 that notifies, when a position with a luminance value equal to or less than the predetermined threshold is determined as being present by the determination part 63, a user of the presence of the position.
