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. In a case where the light source estimated based on the sensor signal is not changed when the category into which the light-source estimation result is classified is changed, it is determined that the light-source estimation result based on the image signal is not reliable, and an adjustment value of white balance adjustment is not updated. Then, the white balance adjustment can accurately and stably be performed.
