Abstract
Provided are a spectral calibration apparatus and a spectral calibration method capable of performing spectral calibration with high accuracy even when peaks appear simultaneously between fluorescent dyes. The spectral calibration apparatus for calculating a color conversion matrix used in color conversion processing, includes a spectral signal acquisition unit that acquires a spectral signal of fluorescence detected over time, a candidate calculation unit that calculates a candidate of the color conversion matrix for each value of a parameter, which depends on a frequency at which fluorescence peaks of fluorescent dyes appear at the same time, based on the spectral signal, and a selection unit that selects a color conversion matrix based on an evaluation value calculated for each candidate.
