Abstract:
A sensor circuit which is capable of measuring illuminance without causing unevenness in results detected with spectral characteristics and a variation in sensitivity regardless of whether or not light receiving elements are evenly irradiated with light includes a plurality of light receiving elements, the light receiving elements each being set to a single spectral characteristic selected from spectral characteristics that are different from each other, and the single spectral characteristic set in each of the light receiving elements being sequentially switched among the spectral characteristics that are different from each other so that the light receiving elements are set to different spectral characteristics during measurement of the illuminance.
