LIGHT SOURCE DEVICE FOR ENDOSCOPE, ENDOSCOPE SYSTEM, AND METHOD FOR OPERATING ENDOSCOPE SYSTEM

摘要

A light source unit is provided with a first light source, a second light source, and a third light source that emit red light, green light, and blue light, respectively, as illumination light. A light source controller controls emission timing of the illumination light to make emission start timing or emission end timing of the first, second, and third light the same and makes an emission period of the red light longer than an emission period of each of the green light and the blue light. An image sensor is capable of separately receiving light of each color reflected from an object of interest irradiated with the illumination light and capable of separately changing a light-receiving period of the light of each color. An imaging controller makes the light-receiving period of at least the red light coincide with the emission period of the red light.

主权项

1. A light source device for an endoscope comprising:
a light source unit that emits each of first light, second light, and third light as illumination light, the first, second, and third light being different in color; a light source controller configured to control emission timing of the illumination light to make emission start timing or emission end timing of the first, second, and third light the same and to make an emission period of the first light longer than an emission period of each of the second light and the third light.
