LENS ADAPTER DEVICE FOR MULTI-SPECTRAL PHOTOGRAPHING, MULTI-SPECTRAL CAMERA AND IMAGE PROCESSOR

摘要

PPROBLEM TO BE SOLVED: To provide a technique for acquiring multi-spectral-image data by using a conventional RGB image-sensing system in spite of a comparatively simple configuration. PSOLUTION: A lens adapter 100 for a multi-spectral photographing is arranged between an object Obj and a photographic lens 200. The lens adapter 100 includes light-guide optical systems 108, 110, 114 and 116 for forming a plurality of object images Im1 and Im2 on the imaging surface of the photographic lens 200 by introducing object lights from the object Obj to the plane of incidence of the photographic lens 200 through a plurality of paths Path 1 and Path 2. The lens adapter further includes a spectral-characteristic changing optical system 112 changing the relative spectral distribution of the object light introduced to the plane of incidence of the photographic lens 200 through either path in the object light proceeding through a plurality of the paths Path 1 and Path 2 so as to differ from the relative spectral distribution of the object lights introduced to the plane of incidence of the photographic lens 200 through other paths.
