Publication number: 20180017773Abstract: The microscope device includes an imager, an image processor, and a controller. In a first period, the controller causes excitation light to be emitted and causes the imager to image a fluorescent image from an activated fluorescent substance in a plurality of frame periods. In a second period, the controller causes a fiducial marker to be irradiated with auxiliary light and causes the imager to image a fluorescent image from the fiducial marker, causes irradiation with the excitation light in the second period to stop or causes the intensity thereof to be reduced to be lower than that in the first period, and causes irradiation with the auxiliary light in the first period to stop or causes the intensity thereof to be reduced to be lower than that in the second period. The image processor uses an imaging result obtained in the second period to correct at least a part of an imaging result obtained in the first period and uses at least a part of the corrected imaging result to generate one image.Type: ApplicationFiled: September 26, 2017Publication date: January 18, 2018Applicant: NIKON CORPORATIONInventors: Wataru TOMOSUGI, Ryosuke KOMATSU
