Patent ID: 8451327

Claim:
An electronic endoscope system, comprising: an electronic endoscope including an imaging device having a first pixel covered with a first color filter penetrated by a first light component that reaches a predetermined depth, according to the location of an object to be observed, under an organ, wherein said first light component comprises one of three primary colors, and said imaging device has a second pixel covered with a second color filter penetrated by a second light component that contains the same primary color as the primary color of said first light component, a wavelength band of the second light component is different than a wavelength band of said first light component, a third pixel covered with a third color filter penetrated by a third light component that contains a different primary color than the primary color of said first light component, and a fourth pixel covered with a fourth color filter penetrated by a fourth light component that contains a different primary color than the primary colors of said first and said third light components, the electronic endoscope further comprising: a light source that emits illumination light to illuminate an object; a light source filter that shields a light component within a predetermined wavelength band from said illumination light; and a filter driver that inserts said light source filter into an optical path of said illumination light, or that removes said light source filter from said optical path.
