Abstract
A fusion splicing device according to one embodiment includes: a discharge electrode; a microscope acquiring luminance information from the optical fiber; a distribution information acquisition unit acquiring distribution information indicating a relationship between a position of the optical fiber in a radial direction and the luminance information; and a core position specification unit specifying a position of a core of the optical fiber from the distribution information. The microscope acquires the luminance information multiple times. The distribution information acquisition unit acquires the distribution information from each of a plurality of the luminance information. The core position specification unit specifies the position of the core of the optical fiber by performing weighting so that a weight of the distribution information based on the luminance information acquired earlier is allowed to be equal to or heavier than a weight of the distribution information based on the luminance information acquired later.
