  • Publication number: 20160061661
    Abstract: A spectroscopic camera is provided with a wavelength variable interference filter including a pair of reflection films and an electrostatic actuator for changing a size of a gap between the reflection films; an imaging unit including a plurality of imaging pixels; and a filter control unit for controlling the electrostatic actuator based on light-received wavelength data in which a control amount for receiving light of a target wavelength is recorded with respect to each of the imaging pixels of the imaging unit. An acquisition order of the target wavelength emitted from the wavelength variable interference filter is set for each of the imaging pixels, and the acquisition order is set in a descending order of the driving amount of a gap, and thus a value for emitting the light of the target wavelength in the set acquisition order is recorded as the light-received wavelength data.
