Abstract:
1. An imaging apparatus comprising: an imaging device that receives visible light and near-infrared light; and a calculation unit configured to calculate a color temperature, wherein the imaging device includes: a first photoelectric converting element that photoelectrically converts visible light transmitted through a first color filter to generate a first visible light signal as a visible light signal, the first color filter transmitting at least the visible light; a second photoelectric converting element that photoelectrically converts near-infrared light transmitted through a second color filter to generate a near-infrared signal, the second color filter transmitting at least the near-infrared light; a third photoelectric converting element that photoelectrically converts visible light transmitted through a third color filter to generate a second visible light signal as a visible light signal, the third color filter transmitting the visible light having a wavelength different from a wavelength of the visible light transmitted by the first color filter, the calculation unit is configured to calculate a second ratio, the second ratio being calculated by dividing the first visible light signal by the second visible light signal, when an amount of the near-infrared signal is not more than a predetermined amount, and the calculation unit is configured to calculate the color temperature based on the second ratio.
