Abstract
A polarization imaging sectionincludes polarized pixels in each of a plurality of polarization directions. The polarization imaging sectionincludes a polarizer. The polarization imaging sectionoutputs image signals of a polarized image to a defect detecting sectionof an image processing section. In a case where a difference between a pixel value of a target polarized pixel generated by the polarization imaging section and a pixel value of the target polarized pixel estimated from polarization characteristics corresponding to pixel values of peripheral pixels in a polarization direction different from a polarization direction of the target polarized pixel is greater than a predetermined allowable range, the defect detecting sectiondetermines that the target polarized pixel is a defective pixel. Therefore, it is possible to detect a defect of a pixel in the polarization imaging section that generates the polarized image.
