  • Patent number: 10829042
    Abstract: An imaging apparatus includes an image sensor and an image processor. The image sensor has at least one type of color filter and a specific filter disposed thereon in a manner corresponding to each pixel on a light receiving surface. The specific filter transmits light in a particular wavelength range in which spectral irradiance of sunlight is lower than that in wavelength ranges adjacent to either side of the particular wavelength range. The image processor detects an emission state of a particular light source based on a signal component of an image signal generated by pixels having the specific filters thereon. The particular light source is different from the sunlight.

  • Patent number: 10742890
    Abstract: An imaging apparatus includes an image sensor and a controller. The controller acquires an infrared image generated by the image sensor when infrared light is higher than a predetermined light amount. The controller acquires a normal image generated by the image sensor when the infrared light is lower than the predetermined light amount. The controller generates a synthesized image on the basis of the infrared image and the normal image. Thus, an image that includes colors and high luminance contrast may be generated in a dark environment without a plurality of infrared light sources.
