1. An image sensor, comprising:
a first filter into which light passed through a first microlens is incident, the first filter having a first spectral characteristic;
a second filter into which the light passed through the first microlens is incident, the second filter having a second spectral characteristic;
a third filter into which light passed through a second microlens arranged adjacent to the first microlens in a first direction is incident, the third filter having the second spectral characteristic;
a fourth filter into which the light passed through the second microlens is incident, the fourth filter having the first spectral characteristic;
a fifth filter into which light passed through a third microlens arranged adjacent to the first microlens in a second direction intersecting the first direction is incident, the fifth filter having the first spectral characteristic;
a sixth filter into which the light passed through the third microlens is incident, the sixth filter having the second spectral characteristic;
a first photoelectric converter that photoelectrically converts the light passed through the first filter into charges;
a second photoelectric converter that is arranged adjacent to the first photoelectric converter in the first direction, the second photoelectric converter converting the light passed through the second filter into charges;
a third photoelectric converter that is arranged adjacent to the second photoelectric converter in the first direction, the third photoelectric converter converting the light passed through the third filter into charges;
a fourth photoelectric converter that is arranged adjacent to the third photoelectric converter in the first direction, the fourth photoelectric converter converting the light passed through the fourth filter into charges;
a fifth photoelectric converter that is arranged adjacent to the first photoelectric converter in the second direction, the fifth photoelectric converter converting the light passed through the fifth filter into charges;
a sixth photoelectric converter that is arranged adjacent to the second photoelectric converter in the second direction and is arranged adjacent to the fifth photoelectric converter in the first direction, the sixth photoelectric converter converting the light passed through the sixth filter into charges;
a first floating diffusion to which charges converted in the first photoelectric converter and charges converted in the fifth photoelectric converter are transferred; and
a second floating diffusion to which charges converted in the second photoelectric converter, charges converted in the third photoelectric converter, and charges converted in the sixth photoelectric converter are transferred.
