Abstract
An imaging apparatus () includes an imaging unit () that has a first pixel block and a second pixel block provided in a pixel region, the first pixel block including polarization pixels with two different polarization directions and a non-polarization pixel, the second pixel block including polarization pixels with a plurality of polarization directions including a different polarization direction from the first pixel block. An image processing apparatus () acquires a captured image generated by the imaging apparatus (), and a correction coefficient calculation unit () calculates a correction coefficient that absorbs a sensitivity difference between polarization pixels and non-polarization pixels, on the basis of an image of the second pixel block. A polarization information generation unit () generates polarization information indicating the polarization characteristics of the object included in the captured image, using a non-polarization image and polarization component images generated by a demosaicing unit () and the correction coefficient calculated by the correction coefficient calculation unit (). The correction coefficient of the sensitivity difference between the polarization pixels and the non-polarization pixels can be acquired without any calibration.
