Imaging device and electronic device

An imaging device comprising:

• a cell array where a plurality of cells are arranged in a matrix;
• and
• a logic circuit,
• wherein each of the plurality of cells includes a photoelectric conversion element,
• wherein each of the plurality of cells is configured to acquire imaging data using the photoelectric conversion element,
• wherein each of the plurality of cells is configured to retain weight data, and
• wherein the logic circuit is configured to perform an arithmetic operation using first imaging data, second imaging data, first weight data, and second weight data in the case where, among the plurality of cells, a first cell acquires the first imaging data, a second cell acquires the second imaging data, a third cell retains the first weight data, and a fourth cell retains the second weight data.
