Abstract: The achromatic region extraction unit calculates achromatic determination information for each color component of the color polarized image using the polarization information acquired from the color polarized image, and extracts a region satisfying a condition that the achromatic determination information is achromatic as an achromatic region. The gain setting unit sets the white balance gain used in the white balance adjustment of the color polarized image on the basis of the white balance gain with which the achromatic region extracted by the achromatic region extraction unit becomes achromatic. For example, the gain setting unit sets the white balance gain for the entire color polarized image on the basis of the white balance gain of the achromatic region, or sets the white balance gain of a region different from the achromatic region on the basis of the white balance gains of a plurality of achromatic regions.

An output unit 70 outputs the detection result of a state change such that the detection result is associated with the non-polarized image generated by the non-polarized image generating unit 40, the detection result being obtained by the state-change detecting unit 60. A state change of the object can be easily detected.
