Imaging element and electronic apparatus

An imaging element, comprising

• a pixel array unit in which a pixel, which includes a polarization member having a polarization direction, and a photoelectric conversion unit configured to receive light transmitted through the polarization member, is disposed in a row direction and a column direction to form a lattice pattern,
• wherein an orientation angle of the polarization member varies depending on a position of the pixel array unit,
• wherein a block, in which the polarization members having angles of transmission axes different from each other by 45° are disposed in two rows and two columns, is disposed in a row direction and column direction to form a lattice pattern, and
• wherein in four pixels included in the block, the orientation angle of the polarization member of a pixel at a position where an orientation from a center of the pixel array unit and an angle of the transmission axis of the polarization member are in a relationship of 0° or 90° is a same as the angle of the transmission axis, and the orientation angle of the polarization member of the pixel at a position which is not in the relationship of 0° or 90° is an angle corrected with a correction amount corresponding to an image height.

An electronic apparatus, comprising:

• an imaging element including a pixel array unit in which a pixel, which includes a polarization member having a polarization direction, and a photoelectric conversion unit configured to receive light transmitted through the polarization member, is disposed in a row direction and a column direction to form a lattice pattern, in which an orientation angle of the polarization member varies depending on a position of the pixel array unit,
• wherein the orientation angle of the polarization member located at a center of the pixel array unit is set to a reference, and
• wherein a correction amount of the orientation angle of the polarization member increases as a distance from a center of the pixel array unit increases;
• and
• a processing unit configured to process a signal from the imaging element.
