Solid image pickup apparatus for eliminating smear

Claim 1

A solid image pickup apparatus for eliminating a smear, comprising: (a) a picture area formed of a plurality of photoelectric converters which are arranged in a two-dimensional matrix and create information charges according to light incident on said photoelectric converters; (b) a store area formed of a plurality of vertical registers which are arranged in association with respective columns of said picture area; (c) first transfer means for transferring, to said vertical registers corresponding to said store area at each column of said picture area, said information charges created in the respective photoelectric converters of said picture area and for transferring, to said store area, smear charges by the transfer of charges, in the absence of said photoelectric converters corresponding to said picture area, by transferring more charges than the number of said photoelectric converters creating said information charges at said columns of said picture area; (d) a horizontal register corresponding to one horizontal line of said store area; (e) second transfer means for transferring the stored charges of said store area; (f) third transfer means for outputting a charge signal corresponding to the charges stored in said horizontal register; (g) storage means for fetching and storing a smear charge signal of one line when the charge signal of the one line transferred by said third transfer means is the smear charge signal; and (h) subtracter means to which the information charge signal outputted from said horizontal register by said third transfer means and the smear charge signal read from said storage means are to be inputted, said subtracter means being capable of performing a subtraction between the inputted two signals.
