Abstract: A spectroscopic measurement apparatus includes an optical system, a photodetector, and an analysis unit. The optical system guides measurement target light from an object to a light receiving surface of the photodetector, and forms a spectral image of the measurement target light on the light receiving. The photodetector includes the light receiving surface on which a plurality of pixels are arranged respectively on a plurality of rows. The photodetector receives the spectral image for a first exposure time by a plurality of pixels in a first region on the light receiving surface, and outputs first spectrum data. The photodetector receives the spectral image for a second exposure time by a plurality of pixels in a second region on the light receiving surface, and outputs second spectrum data. The second exposure time is longer than the first exposure time.
