BEND INFORMATION COMPUTATION APPARATUS, ENDOSCOPE SYSTEM INCLUDING BEND INFORMATION COMPUTATION APPARATUS, BEND INFORMATION COMPUTATION METHOD, AND PROGRAM FOR BEND INFORMATION COMPUTATION

摘要

A bend information computation apparatus is to compute bend information representing a direction and a magnitude of bend of a target group including targets disposed at an identical position along a light guide. Each target modulates the intensity of guided light in accordance with the direction and magnitude of bend. The apparatus includes an input unit to be input detected light quantity information corresponding to each target, a storage to store a bend coefficient and intensity modulation information of each target, and a light quantity information relationship between the bend coefficient and intensity modulation information and the detected light quantity information, a first arithmetic operator to calculate light quantity variation information of each target, based on the detected light quantity information and light quantity information relationship, and a second arithmetic operator to calculate the bend information of the target group, based on the light quantity variation information and bend coefficient.
