Imaging apparatus

Abstract

An imaging apparatus includes an imaging optical system that has a light transmission characteristic of transmitting near-infrared light in a near-infrared light wavelength range including 1550 nm and transmitting visible light in a visible light wavelength range, a switchable filter that selectively transmits the near-infrared light and the visible light, an imaging sensor that has sensitivity to heat radiation from a subject and the visible light, and outputs an imaging signal by selectively transmitting the near-infrared light and the visible light, and an image processor that generates near-infrared image data based on the imaging signal output by imaging the near-infrared light with the imaging sensor, generates visible image data based on the imaging signal output by imaging the visible light with the imaging sensor, and generates image data representing a heat radiation image by subtracting the visible image data from the near-infrared image data.
