Abstract
A measurement device includes a plurality of light sources configured to emit light toward a measurement object, and having a same emission spectrum, a spectroscopic measurement section configured to perform spectroscopic measurement on the light reflected by the measurement object, a light source switching section configured to switch a combination of the light sources to be put on or off out of the plurality of light sources, and an arithmetic section configured to calculate the spectral reflectivity of the measurement object based on a spectroscopic measurement result obtained by the spectroscopic measurement section when putting on or off the plurality of light sources with a plurality of the combinations.
