A solid state imager has a substrate with a plurality of light receiving areas, with vertical registers to transfer charges accumulated in the light receiving areas either through the vertical registers to a horizontal register section and an output terminal, or to a drain region. The transfer is accomplished by use of externally supplied driving pulses. By use of a high-speed normal-transfer operation, charges which are trapped by potential barriers and/or potential dips, and which would normally appear as noise in the form of black spots or bright spots, can be eliminated prior to the read out if the charge signals via the vertical registers and the horizontal register, whereby the output signal is produced free of such noise. |
