Abstract
A spectroscopic camera is provided with a pair of reflecting films, and a wavelength variable interference filter including an electrostatic actuator which can change a size of the gap between the pair of reflecting films, an imaging unit which includes a plurality of pixels which is disposed in a two-dimensional array structure, and receives the light transmitted to the wavelength variable interference filter, and a received-light wavelength acquiring unit which acquires a central wavelength of the light which is incident on the pixel with respect to each of the pixels in the imaging unit, in which the received-light wavelength acquiring unit acquires the central wavelength based on an incidence angle in a position where the light which is received in each of the pixels is incident to the pair of reflecting films.
