Abstract
An image pickup apparatus that enables to quickly capture an image from which a predetermined reflected light component is removed with desired sensitivity. A polarizing filter two-dimensionally arranges a plurality of sets each of which includes polarizing filter elements having different polarization directions. A first image sensor has pixels that respectively correspond to polarizing filter elements of the polarizing filter. A polarization calculation unit detects a polarized component of light that enters into a region in which one set of polarizing filter elements are arranged based on signals output from pixels in the region of the first image sensor for each region. A correction unit corrects a pixel signal output from a pixel of a second image sensor corresponding to the region based on a calculation result by the polarization calculation unit for each pixel of the second image sensor.
