Abstract: An imaging apparatus includes an image sensor, a filter array disposed on an optical path from a target object to the image sensor and including two-dimensionally-arranged optical filters, and a processing circuit that generates at least four pieces of spectral image data based on an image acquired by the image sensor. The optical filters include various types of optical filters with different spectral transmittance. Each of the at least four pieces of spectral image data indicates an image corresponding to one of at least four wavelength bands. The filter array includes at least one characteristic section. The processing circuit detects a relative position between the filter array and the image sensor based on the at least one characteristic section in the image acquired by the image sensor, and compensates for deviation between the relative position and a preliminarily-set relative position when the processing circuit detects the deviation.

Abstract: A filter array includes optical filters that are disposed in a two-dimensional plane. At least one optical filter of the optical filters includes an interference layer having a first surface and a second surface opposite the first surface, and a reflective layer provided on the first surface. A transmission spectrum of the at least one optical filter has maximum values. The reflective layer is not provided on the second surface.
