Measurement device, electronic apparatus and measurement method

A measurement device comprising:

• a plurality of light sources configured to emit first light toward a measurement object, and having a same emission spectrum;
• a spectroscopic filter configured to receive second light reflected by the measurement object irradiated with the first light to output third light with a spectral wavelength;
• a light receiving element configured to receive the third light to output a light reception signal;
• a light source switching section configured to switch a plurality of combinations of the light sources to be put on or off out of the plurality of light sources;
• and
• an arithmetic section configured to calculate a spectral reflectivity of the measurement object based on the reception signal when switching the plurality of light sources between the plurality of combinations.
