Abstract
A spectroscopic measurement device includes a variable wavelength interference filter capable of selectively emitting light with a predetermined wavelength out of incident light, and changing the wavelength of the light to be emitted, a light receiving element adapted to output a detection signal corresponding to a light exposure in response to an exposure to the light emitted from the variable wavelength interference filter, a detection signal acquisition section adapted to obtain a plurality of detection signals different in the light exposure from each other with respect to each of the wavelengths, and a selection section adapted to select the detection signal having a highest signal level out of signal levels of the detection signals obtained, which are lower than a maximum signal level corresponding to a saturated light exposure of the light receiving element.
