Abstract:
An endoscope system includes: a light source apparatus; an endoscope having an imaging unit that includes an image sensor configured to generate color image data imaging biological tissue illuminated by light emitter by the light source apparatus; and a processor that has a first parameter generation unit configured to generate a first parameter that has sensitivity to a first feature amount of the biological tissue but does not have sensitivity to light scattering by the biological tissue based on the color image data, and a first feature amount acquisition unit configured to acquire the first feature amount based on the first parameter.

Claim (Index 26):
An endoscope system comprising:\n a light source apparatus configured to emit first special light that has a different wavelength region from white light and is absorbed by biological tissue differently according to a first feature amount of the biological tissue; an endoscope having an imaging unit that comprises an image sensor configured to generate color image data by imaging the biological tissue illuminated by light emitted by the light source apparatus; and a processor that has a first parameter generation unit and a first feature amount acquisition unit, the first parameter generation unit configured to generate, based on the color image data, a first parameter that is a ratio W/(\u03b2R+\u03b3G) of a first special observation image data W and a sum \u03b2R+\u03b3G,\n the first special observation image data W being obtained by imaging the biological tissue illuminated by the first special light, and being color image data X of an image that has a component in a wavelength region that has sensitivity to the first feature amount of the biological tissue and has sensitivity to light scattering by the biological tissue; and \n the sum \u03b2R+\u03b3G being a sum of obtained by using a coefficient \u03b2 and a coefficient \u03b3 that are set in advance to perform weighted addition on first normal observation image data R and second normal observation image data G that are respectively an R component and a G component of normal observation image data in an RGB color space obtained by imaging the biological tissue illuminated by the white light, and being color image data Y of an image that has a component in a wavelength region that does not have sensitivity to the first feature amount of the biological tissue but has sensitivity to light scattering by the biological tissue, \n the first feature amount acquisition unit configured to acquire the first feature amount based on the first parameter.
