To remove reset noise in pixels while the circuit configuration is kept in low power consumption, a device includes pixels arranged in row and column directions, in which each of the pixels includes a charge-voltage conversion terminal for voltage-converting signal charges transferred from a photoelectric conversion element, and a first reset means for resetting a voltage at the charge-voltage conversion terminal; first signal lines, each of which is connected to the pixels in each column; a scanning means for selecting one row among others; and a second reset means for resetting voltages at the signal lines. In the device, on each selected row, by voltage signals at the charge-voltage conversion terminals and the converted voltage signals from the transferred signal charges are read out to and stored in the signal lines in a floating potential state, and then are output.
