Abstract
A spectral camera includes a wavelength variable interference filter, an imaging unit having a plurality of light receiving elements arranged in a two-dimensional array configuration, and a wavelength acquisition unit which acquires center wavelengths of light beams received by the light receiving elements in accordance with signal values output from the light receiving elements when reference light is received by the imaging unit. Light amounts of the reference light corresponding to different wavelength components in a certain wavelength range are uniform in a plane, and different signal values are acquired when light beams of the different wavelength components are received by the light receiving elements.
