<p>In a CCD (charge-coupled device) device such as a one-dimensional CCD sensor or the like, a signal period during which a signal charge is read out in the intermittent mode can be extended. There is provided a CCD device in which a floating diffusion region is connected through an output gate section to the final stage of a horizontal transfer register of a CCD structure to which a transfer clock pulse is applied and in which a reset gate section is provided between the floating diffusion region and a reset drain region. When a signal charge is read out in the intermittent mode, a clock pulse ( phi OG) is applied to the output gate section to set a potential of the output gate section at low level so that a signal charge of a first pixel is accumulated in a transfer section of final stage. Then, a signal charge of a second pixel is transferred to the transfer section of the final stage by transfer clocks ( phi H1), ( phi H2), ( phi HL), whereby signal charges of two pixels are mixed within the transfer section of the final stage. <IMAGE></p> |
