Abstract: Two kinds of color images, obtained by a solid-state imaging device, having different color tones are combined with each other. A first captured color image due to a first pixel group (pixels in which spectral sensitivities of color filters are wide) of the solid-state imaging device is processed. A second captured color image due to a second pixel group (pixels in which spectral sensitivities of color filters are narrow) is processed. The level difference between captured image signals of the pixels of the first pixel group and captured image signals of the pixels of the second pixel group, and due to the spectral sensitivity difference between the color filters in which the spectral sensitivities are wide and narrow is obtained (steps S1 and S2). The level difference is corrected. The first captured color image and the second captured color image are combined with each other.

Abstract: An imaging apparatus includes 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. 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.
