FLUORESCENCE OBSERVATION APPARATUS, FLUORESCENCE OBSERVATION SYSTEM, AND METHOD FOR PROCESSING FLUORESCENCE IMAGE

摘要

Provided is a fluoroscopy apparatus that allows examination with a highly quantitative fluorescence image by sufficiently removing the residual dependence on factors such as distance from a divided image. Employed is a fluoroscopy apparatus (100) including a preprocessing section (46) that multiplies at least one of a fluorescence image and a reference-light image by a coefficient by which distance characteristics of fluorescence intensity and distance characteristics of return-light intensity acquired from a standard sample in advance are made directly proportional to each other to generate a correction fluorescence image and a correction reference-light image; a divided-image generating section (43) that divides the correction fluorescence image by the correction reference-light image to generate a divided image; a threshold-setting section (45) that sets a threshold based on a mean grayscale level of pixels in the divided image; an image-adjusting section (51) that enhances contrast between a region with grayscale levels above the set threshold set by the threshold-setting section and a region with grayscale levels below the threshold in the divided image; and a monitor (50) that displays the divided image with the enhanced contrast.
