Imaging apparatus and imaging method

There is provided an imaging section that allows multiple pixels generating a pixel signal based on incident light to act as polarization pixels each having one of multiple polarizing directions. A polarization element is attached on the side of the incidence plane side of the imaging section, causes linearly polarized light to enter the imaging section. A control section, for example, controls a sensitivity detecting section to detect a sensitivity level in each of the polarizing directions of the polarization pixels in the imaging section. An image signal processing section performs gain adjustment on the polarization pixels on the basis of the sensitivity level detected in each of the polarizing directions by the sensitivity detecting section, and carries out image composition using the gain-adjusted image signals to generate a captured image having wide dynamic range with minimum motion blur.
