Abstract:
An endoscope apparatus includes: an image pickup portion that, with respect to return light including a plurality of wavelength band components that is generated accompanying irradiation of illuminating light onto an object, receives the return light with a plurality of different spectral sensitivities and generates an image pickup signal for each of the spectral sensitivities; a correction portion that, based on a spectral distribution of the return light and spectral sensitivity characteristics of the image pickup portion, sets a correction coefficient so that spectral distributions for each of the plurality of wavelength band components included in the image pickup signals become a similar shape to each other; and a calculation portion that, based on the correction coefficient, performs a calculation that separates image pickup signals into each wavelength band component among the plurality of wavelength band components included in the return light.
