| 1. An image sensor comprising plural light detecting element rows each having plural light detecting elements and a color
filter provided on each light detecting element, in which the light detecting element rows are arranged such that centers
of gravity of light detecting parts of the light detecting elements in the respective light detecting element rows, are arranged
at a constant pitch:
wherein a driving circuit part for reading an electrical signal from each light detecting element is provided for each light
detecting element; and
wherein a pitch L of the light detecting elements along a direction of array thereof in the plural light detecting element
rows, a pitch nL (n being a positive integer) of the plural light detecting element rows in a direction of arrangement thereof,
a width k of the driving circuit part along the direction of arrangement of the plural light detecting element rows, a width
a of a first light detecting aperture with a largest area among the plural light detecting element rows along the direction
of arrangement of the plural light detecting element rows, and a width b of a second light detecting aperture with a second
largest area among the plural light detecting element rows along the direction of arrangement of the plural light detecting
element rows are selected that the width a satisfies a following relation:
(a/2)+k+(b/2)=nL.
