Image sensor and imaging apparatus with sensitivity versus incident angle ranges for 2D and 3D imaging

摘要

An image sensor includes: a plurality of pixels arranged and formed in a two-dimensional array so that adjacent ones of the pixels constitute paired pixels and entrance pupils of a first pixel and a second pixel constituting the paired pixels are provided eccentrically in opposite directions to each other with respect to centers of the respective pixels; an incident angle of light from a subject in the first pixel is an incident angle θcA as defined herein; the incident angle in the second pixel is an incident angle −θcB as defined herein; and light sensitivity characteristics of the first pixel and the second pixel with respect to the incident angles of the first pixel and the second pixel are flat characteristics within an incident angle range of the θcA to the −θcB.
