Abstract:
1. A living body observation device comprising: a signal processing control unit for controlling operation of an illumination source for irradiating a living body being a subject with light or an image pickup unit for photoelectrically converting light reflected from the living body based on the illumination light from the illumination source and for generating an image pickup signal, or operations of both the illumination source and the image pickup unit, and for outputting the image pickup signal to a display device; a spectral signal generation unit for generating a spectral signal corresponding to a band image of a discrete spectral distribution of said subject from the image pickup signal by signal processing for estimating the spectral signal; and a color adjustment unit for adjusting a color tone for each of a plurality of bands forming the spectral signal when the spectral signal is outputted to the display device, wherein a spectral characteristics control unit for controlling spectral characteristics of light on an optical path by increasing intensity or sensitivity in a partial wavelength region of the illumination light compared to intensity or sensitivity in other wavelength regions of the illumination light by a spectral intensity control unit for controlling spectral intensity characteristics of the illumination light or an image pickup device spectral sensitivity control unit for controlling spectral sensitivity characteristics of an image pickup device in the image pickup unit is further provided on the optical path from the illumination source to the image pickup unit.
