ABSTRACT:
A solid state imaging device having a horizontal transfer register formed of a plurality of transfer sections for alternately transferring a signal charge of the same pixel in the horizontal direction wherein a signal charge can be distributed between respective transfer sections in consideration of the amount of signal charges handled by the respective transfer section. In a first horizontal transfer register (4) having transfer sections (4a) and (4b), a control gate section (5) that distributes signal charges between the respective transfer sections (4a) and (4b) has on its one region a potential barrier section (13) formed along the horizontal transfer direction. After a signal charge of the amount determined by an area of that region and a potential (height) of the potential barrier section (13) was accumulated in the control gate section (5) at its region where the potential barrier section (13) is not formed, the signal charge is distributed between the transfer sections (4a) and (4b) by holding the potential of the potential barrier section (13 ) at middle level.
