Abstract:
1. An image sensor comprising: 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; wherein: an incident angle of light from a subject in the first pixel is an incident angle θcA which is within a range between 0° corresponding to a normal direction of the pixels and an incident angle θmaxa at a maximum light sensitivity, and in which the light sensitivity of the first pixel is within a range of from 40% to 80% of the maximum light sensitivity; the incident angle in the second pixel is an incident angle −θcB which is within a range between 0° corresponding to the normal direction of the pixels and an incident angle θmaxb at the maximum light sensitivity, and in which the light sensitivity of the second pixel is within a range of from 40% to 80% of the maximum light sensitivity; 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 wherein the characteristics are flat when the difference between the light sensitivity of the first pixel and the light sensitivity of the second pixel is in a range not lower than 0 and not higher than 0.05 on the assumption that the maximum light sensitivity is set as 1.
