  • Publication number: 20210168345
    Abstract: An imaging unit 23 generates an image signal of a captured image. An optical sensor unit 25 generates a sensor signal that has a wider view angle than that of the imaging unit 23 and is according to a spectral characteristic upon obtaining the captured image. A controller 50 determines reliability of a light-source estimation result based on the image signal generated by the imaging unit 23, using a light-source estimation result based on the sensor signal generated by the optical sensor unit 25. For example, the controller 50 classifies the light-source estimation result based on the image signal into categories of light sources capable of being estimated based on the sensor signal, and compares the category into which the light-source estimation result is classified with the light source estimated based on the sensor signal.
