Abstract
An imaging apparatus includes a solid-state imaging device and a driving unit. The solid-state imaging device has a plurality of pairs of first and second photoelectric conversion elements having different spectral sensitivity characteristics. The driving unit independently controls an exposure time of a first group of the plurality of first photoelectric conversion elements and an exposure time of a second group of the plurality of second photoelectric conversion elements. A wavelength range where the first photoelectric conversion element of each pair mainly has a spectral sensitivity and a wavelength range where the second photoelectric conversion element of each pair mainly has spectral sensitivity fall within the respective wavelength ranges of specific colors of visible light. A half width in the spectral sensitivity characteristic of each first photoelectric conversion element is wider than a half width in the spectral sensitivity characteristic of each second photoelectric conversion element of the pair.
