    • PROBLEM TO BE SOLVED: To provide a light measurement system capable of improving correctness of estimation of absorbance component density.SOLUTION: In an electronic endoscope system 15 shown as one example of the light measurement system, an observed portion is irradiated with an excitation light to excite Indocyanine green injected in a blood vessel to allow it to emit a light, and the Indocyanine green is subjected to image pickup to estimate the depth of the blood vessel from the surface of the observed portion on the basis of an image pickup signal obtained by the image pickup. Further, the oxygen saturation of hemoglobin is estimated on the basis of an image pickup signal obtained by irradiating the observed portion with at least two kinds of narrow band lights having different wavelength band. In estimating the oxygen saturation, an estimation algorithm of the oxygen saturation is changed so that the observation conditions meet a result of estimation of the depth of the blood vessel.
    • 要解决的问题:提供能够提高吸光度成分密度的估计的正确性的光测量系统。 解决方案:在作为光测量系统的一个实例示出的电子内窥镜系统15中,用激发光照射观察部分,以激发注射在血管中的吲哚菁绿以使其发光,并且吲哚菁 绿色经受图像拾取,基于通过图像拾取获得的图像拾取信号从观察部分的表面估计血管的深度。 此外,基于通过用至少两种具有不同波长带的窄带光照射观察部分而获得的摄像信号来估计血红蛋白的氧饱和度。 在估计氧饱和度时,改变氧饱和度的估计算法,使得观察条件符合估计血管深度的结果。 版权所有(C)2012,JPO&INPIT
