Abstract
Official abstract text for this publication.
A light source device of an electronic endoscope system has first and second semiconductor lasers. In a vascular observation mode, one of the semiconductor lasers is used in a full light state (100% rated output) while the other is used in a reduced light state (for example, 10% rated output). First and second images of an internal body portion are captured with a color imaging device under illumination of two patterns, respectively. Correlation operation of pixel values of three colors is performed between the two images. Noise components, caused by the first or second semiconductor lasers in the light reduced state, are removed from the first and second images. An oxygen saturation level of blood in a blood vessel is calculated using the first and second images with the noise components removed.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic endoscope system comprising: at least first and second light source systems configured to illuminate an internal body portion including a blood vessel from an insert section to be inserted into a body, the first light source system generating first illumination light including first narrowband light, the second light source system generating second illumination light including second narrowband light, the first light source system having a firs…
