Abstract:
A solid-state electronic image sensing device comprising:a number of photoelectric transducers arrayed in vertical and horizontal directions; vertical transfer lines, on which vertical transfer electrodes are formed in correspondence with said photoelectric transducers, for transferring signal charge, which has accumulated in said photoelectric transducers, in the vertical direction by application of vertical transfer pulses to the vertical transfer electrodes; a horizontal transfer line for transferring in the horizontal direction and outputting signal charge that has been transferred from said vertical transfer lines; a charge sweep-out drain for sweeping out signal charge input thereto; and a controller which, when vertical downsampling readout is performed, is for controlling said vertical transfer lines and said horizontal transfer line in such a manner that of signal charge that has accumulated in a plurality of rows of said photoelectric transducers, signal charge that has accumulated in at least one row of these photoelectric transducers is output from said horizontal transfer line, and controlling said vertical transfer lines and said horizontal transfer line in such a manner that smear charge, which is produced in vertical transfer lines between the vertical transfer electrodes corresponding to the photoelectric transducers of said one row, is applied to said charge sweep-out drain and is swept out from said charge sweep-out drain.
