Abstract

The invalid pixel detection unitdetects an invalid pixel from a non-polarized image and a plurality of polarized images for different polarization directions obtained by performing image pickup using the polarization image pickup unit. For example, the invalid pixel detection unitdetects a saturated pixel having a pixel value larger than a preset saturation detection threshold and a black-crushed pixel having a pixel value smaller than a preset black crushing detection threshold as invalid pixels from a non-polarized image. The polarization information generation unitperforms processing of generating polarization information on the basis of the non-polarized image and polarized images and switches the processing of generating the polarization information depending on the detection result of the invalid pixels in the invalid pixel detection unit, so as to generate the polarization information without using the invalid pixels. Correct polarization information can be acquired.
