Abstract:
1. An imaging apparatus comprising a solid-state imaging device that has a plurality of pairs of a first photoelectric conversion element and a second photoelectric conversion element, which have different spectral sensitivity characteristics, respectively, wherein 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 the pair mainly has a spectral sensitivity fall within wavelength ranges of specific colors of visible light respectively, the plurality of pairs include a plurality of types of pairs having different specific colors, a half-width in a spectral sensitivity characteristic of the second photoelectric conversion element of each pair is wider than a half width in a spectral sensitivity characteristic of the first photoelectric conversion element of the pair, the imaging apparatus further comprising: a first signal generating unit that generates a first luminance signal and a first color signal using an imaging signal outputted from the plurality of first photoelectric conversion elements and generate a second luminance signal and a second color signal using an imaging signal outputted from the plurality of second photoelectric conversion elements; a second signal generating unit that generates a third luminance signal for a recordation to a recording medium using at least one of the first luminance signal and the second luminance signal and generate a third color signal for a recordation to the recording medium using at least one of the first color signal and the second color signal; and a light-measuring unit that obtains the imaging signals outputted from each of the first photoelectric conversion elements and each of the second photoelectric conversion elements to perform photometry, wherein the second signal generating unit changes a generating method of the third luminance signal and a generating method of the third color signal based on results of the photometry performed by the light-measuring unit.
