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 an imaging sensor that outputs an imaging signal by imaging the near-infrared light transmitted through the imaging optical system, the imaging sensor has sensitivity to heat radiation from a subject, and the imaging signal includes information regarding a heat radiation image by the heat radiation.
Claims10
An imaging apparatus, comprising:
- 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;
- an imaging sensor that has sensitivity to heat radiation from a subject and outputs an imaging signal including information regarding a heat radiation image resulting from the heat radiation by imaging the near-infrared light transmitted through the imaging optical system;
- a light source that emits the near-infrared light;
- a light source drive controller that applies temporal modulation to an intensity or a frequency of the near-infrared light emitted from the light source by driving of the light source;
- and
- an image processor that generates first image data representing a subject image according to the near-infrared light, and second image data representing the heat radiation, based on a direct-current component and a modulated component of the imaging signal,
- wherein the image processor generates the first image data based on the modulated component and generates the second image data based on the direct-current component.
