内視鏡装置、内視鏡装置の作動方法及びプログラム
Document Type and Number:
Japanese Patent JP7019039
Kind Code:
B2
Abstract:
An endoscope apparatus includes an illumination device generating illumination light including a first light, a second light, and a third light, an imaging device capturing an image based on return light from biological tissue, and a processor configured to perform image processing based on first, second, and third images respectively corresponding to the first light, the second light, and the third light. The first light has a peak wavelength within a predetermined wavelength range including a wavelength achieving a largest value of a hemoglobin absorption coefficient. The second light has a peak wavelength between a wavelength achieving a smallest value of the hemoglobin absorption coefficient and a wavelength achieving a first maximum value of the hemoglobin absorption coefficient on a shorter wavelength side of the wavelength achieving the smallest value. The third light has a peak wavelength between the peak wavelengths of the first light and the second light.
