IMAGE SENSOR, IMAGING APPARATUS, AND IMAGE PROCESSING DEVICE

摘要

An image sensor captures a subject image of a partial luminous flux passed through different regions from among a total luminous flux through one optical system. The image sensor is configured from a pixel arrangement in which a plurality of each of at least three types of pixels are arranged, including non-parallax pixels which comprise an aperture mask that produces a viewpoint in a reference direction, first parallax pixels which comprise an aperture mask that produces a viewpoint in a first direction different from the reference direction and second parallax pixels which comprise an aperture mask that produces a viewpoint in a second direction different from the reference direction, wherein each of the aperture mask of the first parallax pixels and the aperture mask of the second parallax pixels has a width of a greater-than-half-aperture aperture area in the direction of change of the viewpoint.

主权项

1. An image sensor comprising:
a plurality of non-parallax pixels, each of which includes a non-parallax aperture mask arranged to pass a full or partial luminous flux of a subject image through an optical system so as to produce a viewpoint in a reference direction; a plurality of first parallax pixels, each of which includes a first aperture mask arranged to pass a partial luminous flux of the subject image through the optical system so as to produce a viewpoint in a first direction different from the reference direction, an aperture area of the first aperture mask having a greater-than-half-aperture width in the direction of change from the reference direction to the first direction; and a plurality of second parallax pixels, each of which includes a second aperture mask arranged to pass a partial luminous flux of the subject image through the optical system so as to produce a viewpoint in a second direction different from the reference direction and different from the first direction, an aperture area of the second aperture mask having a greater-than-half-aperture width in the direction of change from the reference direction to the second direction.
