Abstract
An image sensor includes a first photoelectric conversion unit that converts light incident through a first opening to an electric charge, a second photoelectric conversion unit that converts light incident through a second opening which is smaller than the first opening to an electric charge, and a signal output wiring that outputs a first signal generated by the electric charge converted by the first photoelectric conversion unit and a second signal generated by the electric charge converted by the second photoelectric conversion unit. The second photoelectric conversion unit is disposed between the second opening and the signal output wiring.
Claims20
An image sensor comprising:
- a first member having a first opening through which light is transmitted from a first microlens;
- a second member having a second opening through which light is transmitted from a second microlens, an opening area of the second opening being smaller than an opening area of the first opening;
- a first photoelectric converter that converts light from the first opening to an electric charge;
- a second photoelectric converter that converts light from the second opening to an electric charge;
- first signal output wiring that outputs a first signal generated by the electric charge converted by the first photoelectric converter, and
- second signal output wiring that outputs a second signal generated by the electric charge converted by the second photoelectric converter, wherein
- the second photoelectric converter is disposed between the second member and the first signal output wiring in an optical axis direction of the second microlens.
