Abstract:
1. A driving method of a solid-state imaging apparatus that includes a plurality of signal holding units, each having an input node to which a signal is supplied from an output node of a pixel, a plurality of selecting units, one of each arranged correspondingly to one of the signal holding units, to transfer the signal held in the signal holding unit, and a plurality of reference level supply units, each arranged correspondingly to a predetermined number of the signal holding units, to supply a reference level to an output node of a corresponding signal holding unit through a corresponding selecting unit, the driving method comprising steps of: for a plurality of pixels in a row, performing a clamping operation for sampling and holding a signal outputted from a pixel in a signal holding unit, by decaying turn ON pulses to be supplied to the selecting units in separate timings to turn off the selecting units successively, one for each one of the selecting units, or one for each group of the selecting units while each of reference level supply units outputs the reference level; and for the plurality of pixels in the row, selecting signal holding units through the selecting units by supplying the turn ON pulses successively to the selecting units, so as to read out signals successively from the signal holding units selected.
