Abstract
An imaging apparatus includes: a first imaging device configured to perform photoelectric conversion on subject light input through a first filter to output a first image signal, the first filter preventing light in a predetermined wavelength band of wavelengths longer than that of visible light from being transmitted; a second imaging device arranged at a different position from the first imaging device and configured to perform photoelectric conversion on subject light containing a wavelength component of the light in the predetermined wavelength band to output a second image signal; a correlation detection unit configured to detect a correlation between the first and second image signals; a luminance signal generation unit configured to generate a luminance signal; a color signal generation unit configured to generate a color signal; and a three-dimensional image generation unit configured to generate a three-dimensional image by the correlation, the luminance signal, and the color signal.
