摘要
An embodiment of the present invention is a shape estimating device including an input unit, a storage unit, and a shape calculating unit. The input unit is configured to receive light-intensity information representing a relationship between wavelength and light intensity, the light-intensity information being acquired by using a sensor configured such that a light intensity detected for a wavelength associated with at least one detected part group including a plurality of detected parts disposed at substantially the same position along an optical-axis direction of a light guide member varies depending on bend information representing the direction and magnitude of bending of the detected part group. The storage unit stores a light-intensity estimating relationship including bend characteristic information representing relationships among shapes, wavelengths, and light intensities about the detected part group. The shape calculating unit calculates bend information about the detected part group on the basis of the light-intensity information and a light-intensity estimating value representing a relationship between a wavelength and a light intensity, the light-intensity estimating value being calculated on the basis of the light-intensity estimating relationship. Other embodiments of the present invention are an endoscope system including the shape estimating device, a bend-information estimating method, and a program.
