Solid-state image sensor, imaging device, and method of controlling solid-state image sensor

An imaging device, comprising:

• an array unit including a plurality of sets of charge storage units, wherein
• each set of the plurality of sets of charge storage units includes a specific number of a plurality of charge storage units in a 2-dimensional lattice arrangement,
• each set of the plurality of sets of charge storage units is in a specific direction, and
• each of the plurality of charge storage units is configured to store charges generated through photoelectric conversion;
• a first connection line for a first set of the plurality of sets of charge storage units;
• a second connection line for a second set of the plurality of sets of charge storage units;
• a connection path opening and closing unit configured to open and close a first path between a respective charge storage unit of the plurality of charge storage units and one of the first connection line or the second connection line that corresponds to the respective charge storage unit;
• an inter-line path opening and closing unit comprising a switch configured to open and close a second path between the first connection line and the second connection line;
• a scanning circuit configured to:
• control the connection path opening and closing unit and the inter-line path opening and closing unit;
• and
• cause addition of an amount of the charges of the specific number of the plurality of charge storage units of an addition target based on the control of the connection path opening and closing unit and the inter-line path opening and closing unit;
• and
• a recording unit configured to record image data, wherein
• the image data includes pixel signals based on the amount of the charges.

A method of controlling a solid-state image sensor, the method comprising:

• opening and closing, by a connection path opening and closing unit, a first path between a respective charge storage unit and one of a first connection line or a second connection line that corresponds to the respective charge storage unit, wherein
• the first connection line is for a first set of a plurality of sets of charge storage units in an array unit,
• the second connection line is for a second set of the plurality of sets of charge storage units in the array unit,
• each set of the plurality of sets of charge storage units includes a specific number of a plurality of charge storage units in a two-dimensional lattice arrangement,
• each set of the plurality of sets of charge storage units is in a specific direction, and
• each of the plurality of charge storage units is configured to store charges generated through photoelectric conversion;
• and
• opening and closing, by an inter-line path opening and closing unit comprising a switch, a second path between the first connection line and the second connection line.
