Abstract
An imaging device includes: a first pixel including a first photoelectric converter that converts incident light into first signal charges, and a first charge storage node that accumulates the first signal charges; and a second pixel including a second photoelectric converter that converts incident light into second signal charges, and a second charge storage node that accumulates the second signal charges. An area of the second photoelectric converter is greater than an area of the first photoelectric converter in a plan view. Capacitance of the first charge storage node is greater than capacitance of the second charge storage node.
Claims20
An imaging device comprising:
- a first photoelectric converter that converts incident light into first signal charges;
- a first node into which the first signal charges are input;
- a second photoelectric converter that converts incident light into second signal charges;
- and
- a second node into which the second signal charges are input, wherein
- an area of the second photoelectric converter is greater than an area of the first photoelectric converter in a plan view, and
- capacitance of the first node is greater than capacitance of the second node.
An imaging device comprising:
- a first photoelectric converter that converts incident light into first signal charges;
- a first node into which the first signal charges are input;
- a capacitive element connected to the first node;
- and
- a second photoelectric converter that converts incident light into second signal charges, wherein
- an area of the second photoelectric converter is greater than an area of the first photoelectric converter in a plan view.
An imaging device comprising:
- a first photoelectric converter that converts incident light into first signal charges;
- a first node into which the first signal charges are input;
- a capacitive element connected to the first node;
- and
- a second photoelectric converter that converts incident light into second signal charges, wherein
- at least a portion of the capacitive element does not overlap with the first photoelectric converter in a plan view.
