Abstract (in Japanese) (See Japanese page) 
(in English) With the increase of colorectal cancer patients in recent years, the computer-aided diagnosis (CAD) system which supports doctor's diagnosis effectively in the diagnosis of colon cancer is required. Our research describe the support system for colorectal endoscopic images with narrow band imaging (NBI) magnification which identify the pathology type from local features in NBI endoscopic image. In order to meet the real time processing in which a full high definition (Full HD) endoscopic image must be identified within one second, the feature transformation which change feature quantity to VW histogram is implemented on hardware. For implementation on FPGA which has the resource limitations, we propose the architecture that uses Manhattan distance in class searching, and enables high speed processing by dynamic computation of normalization. As a result, it allows the feature transformation to complete its work in about 334 msec on the full HD image. More over, the architecture can improve the processing time to about 43 msec by pipelining.
