多谱图像捕捉装置
摘要：
半镜(12)将来自物体(O)的光分成两个光路。通过红外光截止滤波器(18)对一部分光进行滤波，使得遮挡近红外光，并在彩色CCD图像捕捉设备(14)上将所得光形成图像。由此，获得具有标准RGB的频谱灵敏度特性的三个频带的图像。通过透过带宽近似为RGB的波长带宽一半的光的带通滤波器(20)对另一部分光进行滤波，并在彩色CCD图像捕捉设备(16)上将所得光形成为图像。由此，获得具有比RGB的带宽要窄的带宽的频谱特性的三个频带的图像。
摘要（英）：

A light from an object (O) is split into two light paths by a half mirror (12), and one light, having its near-infrared light cut off through an infrared cut filter (18), is imaged on a color CCD imaging element (14) to obtain a 3-band image by the spectral sensitivity characteristics of standard RGB. The other light is passed through a band pass filter (20) that passes lights in bands about half the respective wavelength bands of RGB to image it on a color CCD imaging element (16), thereby obtaining a 3-band image having spectral characteristics in a band narrower than those of RGB.
