A solid-state image capturing element includes a pair of first floating diffusion layers arranged in a direction perpendicular to a predetermined direction and a pair of second floating diffusion layers arranged in the perpendicular direction and adjacent to the pair of first floating diffusion layers in the predetermined direction. The element includes a first connection circuit configured to select at least one of the pair of first floating diffusion layers and to connect the selected first floating diffusion layer to a predetermined first wire; a second connection circuit configured to select at least one of the pair of second floating diffusion layers and to connect the selected second floating diffusion layer to the first wire; and an output circuit configured to output a signal according to an amount of charge of at least one of the pair of first floating diffusion layers or the pair of second floating diffusion layers.
