A solid-state imaging device includes: a plurality of light-receiving elements which are arranged by rows and columns; a plurality of vertical transfer units each of which is arranged for a corresponding column of the light-receiving elements, and vertically transfers a plurality of signal packets and dummy packets, the signal packet including charges read from the light-receiving elements, the dummy packets being packets other than the signal packets, and N columns of the vertical transfer units forming one column group; a plurality of hold units which are arranged for final stages of the vertical transfer units in N columns except M column in the column group, and each of which mixes, holds, and vertically transfers charges of the signal packets and the dummy packet without depending on vertical transfer from upstream of the corresponding vertical transfer unit; a horizontal transfer unit which mixes, holds, and horizontally transfers the charges transferred from the hold units or the vertical transfer units in the M column in the column group; and a driving unit which drives the vertical transfer units, the hold units, and the horizontal transfer unit, wherein the driving unit perform the driving, so that a signal packet and a plurality of dummy packets in an identical column are mixed together into a mixed packet in each of the holding units, charges of the mixed packet are held in the hold unit, the held charges of the mixed packet are vertically transferred to the horizontal transfer unit so that the mixed packet is mixed with a mixed packet of a different hold unit which is vertically transferred from the different hold unit to the horizontal transfer unit.
