Title:
FLUORESCENCE OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/126065
Kind Code:
A1
Abstract:
Provided is a fluorescence observation device capable of correcting fluorescence intensity change dependent on the observation distance, observation angle, and the like of a fluorescence image according to the observation condition. Adopted is a fluorescence observation device (1) provided with a light source (3) which applies excitation light and white light to an object to be observed (X), a fluorescence image generation unit (21) which captures an image of fluorescence generated in the object to be observed (X) by the application of the excitation light and acquires a fluorescence image, a reference image generation unit (20) which captures an image of return light that returns from the object to be observed (X) by the application of the white light and acquires a reference image, an observation condition determination unit (22) which determines the observation condition of the object to be observed (X) from the reference image acquired by the reference image generation unit (20), a previous stage processing unit (24) which corrects the gradation value of the reference image on the basis of the observation condition of the object to be observed (X), and a fluorescence image correction unit (25) which divides the fluorescence image acquired by the fluorescence image generation unit (21) by the reference image the gradation value of which is corrected by the previous stage processing unit (24) to generate a corrected fluorescence image.
