Abstract
A solid-state image sensor includes: four or more photoelectric conversion units having spectral sensitivity characteristics different from one another; an amplifier unit disposed in correspondence to each group of photoelectric conversion units among N groups (N represents an integer less than a quantity of the four or more photoelectric conversion units and equal to or greater than one), the four or more photoelectric conversion units being divided into the N groups; and transfer units, each disposed in correspondence to one of the four or more photoelectric conversion units, which transfer a signal generated at the photoelectric conversion unit to the amplifier unit disposed for the group to which the photoelectric conversion unit belongs.
