Abstract:
1. A solid-state image capturing element, comprising: a plurality of pixels arranged in rows and columns, each of the pixels outputting an electric signal corresponding to an amount of received light; a plurality of column signal lines each of which is disposed for a corresponding one of columns of the pixels and sequentially transfers the electric signal provided from the corresponding one of the columns of the pixels; a plurality of holding circuits each of which is disposed for a corresponding one of the column signal lines and holds the electric signal transferred via the corresponding one of the column signal lines; and a plurality of reading column lines, wherein each of the holding circuits includes a circuit element including an input capacitance, and holds the electric signal in the input capacitance, the circuit element is a holding transistor, the input capacitance is a gate capacitance of the holding transistor, each of the holding circuits includes: the second transistor is connected to a corresponding one of the reading column signal lines at the other of the source and the drain of the second transistor, and each of the holding circuits, when holding the electric signal in the holding transistor, holds the electric signal while amplifying the electric signal, by bringing the first transistor and the second transistor into conduction.
