Imaging apparatus

An imaging apparatus that generates image data for detecting vital information on a subject, the apparatus comprising:

• an imaging element that generates the image data by photoelectrically converting light received by each of a plurality of pixels arranged two-dimensionally;
• a filter array including a unit including a plurality of visible light filters with different transmission spectrum maximum values within a visible light band, and invisible light filters having a transmission spectrum maximum value in an invisible light range of wavelengths longer than those of the visible light band, the visible light filters and the invisible light filters being disposed in correspondence with the plurality of pixels;
• an optical filter disposed on a light-receiving surface of the filter array, the optical filter transmitting light included in either a first wavelength band that includes the respective transmission spectrum maximum values of the plurality of visible light filters or a second wavelength band that includes the transmission spectrum maximum value of the invisible light filters;
• and
• a first light source that emits, toward the subject, light having a wavelength within the second wavelength band, light of a first wavelength having a half-value width less than or equal to half of the second wavelength band.
