Title:
SUBJECT OBSERVATION SYSTEM AND METHOD, AND CAPSULE ENDOSCOPE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/104095
Kind Code:
A1
Abstract:
A subject observation system comprises a subject observation light source and an image acquisition unit. The subject observation light source emits observation light including a spectral component with a predetermined wavelength and irradiates a subject therewith. The image acquisition unit captures an image of reflected light from an irradiated region of the subject, and acquires at least two observation images in different wavelength regions on the basis of a plurality of image signals corresponding to a blue region, a green region, and a red region. The observation light includes the component of an emission spectrum in each of the blue region, the green region, and the red region. The emission spectrum in the blue region is smaller in a wavelength region where the absorption intensity of a specified object to be observed in the subject is relatively low than in the other regions.
