要約
(EN)
A subject is simultaneously exposed to broadband light (BB) and narrowband light (NB). Said subject is imaged using a color CCD (33), yielding a blue signal (B), a green signal (G), and a red signal (R). A base image is generated from said signals (B, G, and R), and a B/G image is generated from the B/G ratio, i.e. the ratio of the blue signal (B) to the green signal (G). Pixels representing B/G ratios less than or equal to a mucous-membrane/superficial-blood-vessel boundary value (Ls) are extracted from the B/G image, yielding an image containing extracted superficial blood vessels, and pixels representing B/G ratios greater than or equal to a mucous-membrane/mid-depth-blood-vessel boundary value (Ld) are extracted, yielding an image containing extracted mid-depth blood vessels. Said boundary values (Ls and Ld) are different for each observation mode.

(ZH)
本发明提供一种内窥镜系统、内窥镜系统的处理器装置以及图像处理方法,即使要观察的部位发生了变化也能够可靠地提取深度不同的多个种类的血管。对被检体同时照射宽波段光(BB)和窄波段光(NB)。通过彩色CCD(33)对该被检体进行摄像而得到蓝色信号(B)、绿色信号(G)、红色信号(R)。根据这3个颜色的信号(B、G、R)生成基本图像。生成由蓝色信号(B)和绿色信号(G)间的信号比即B/G比构成的B/G图像。在B/G图像中,通过提取B/G比为粘膜与表层血管的边界值(Ls)以下的像素,得到表层血管提取图像。通过提取B/G比为粘膜与中深层血管的边界值(Ld)以上的像素,得到中深层血管提取图像。这些边界值(Ls、Ld)按照观察模式而不同。
