Solid-state imaging device and electronic camera

摘要

In a solid-state imaging device and an electronic camera, a first substrate of the solid-state imaging device includes first and second photoelectric converting units, a transfer unit that transfers signal charges of the first and second photoelectric converting units to a connector, and a microlens that causes light to be incident on the first and second photoelectric converting unit. A second substrate of the solid-state imaging device includes first and second memory units that hold signal charges transferred from one or the other of the first and second photoelectric converting unit to the connector and an averaging unit that averages the signal charges held in the first memory unit and the signal charge held in the second memory unit.

1. A solid-state imaging device, comprising:
a first substrate; a second substrate; and a connector configured to connect the first substrate with the second substrate, wherein the first substrate includes
a first photoelectric converting unit,a second photoelectric converting unit,a transfer unit configured to transfer signal charges of the first photoelectric converting unit and signal charges of the second photoelectric converting unit to the connector, anda microlens configured to cause light to be incident on the first photoelectric converting unit and the second photoelectric converting unit, the second substrate includes
a first memory unit configured to hold the signal charges as an analog signal transferred from one of the first photoelectric converting unit and the second photoelectric converting unit to the connector,a second memory unit configured to hold the signal charges as another analog signal transferred from the other of the first photoelectric converting unit and the second photoelectric converting unit to the connector, andan averaging unit configured to average the signal charges held in the first memory unit and the signal charges held in the second memory unit, andat least one of the first substrate and the second substrate includes a control unit configured to perform a control in a first mode in which focus detection signals are individually read based on the signal charges held in the first memory unit and the signal charges held in the second memory unit and to perform a control in a second mode in which an imaging signal is read based on the signal charges averaged by the averaging unit.
