ABSTRACT:
A solid-state image pickup apparatus of the type from which signal charge can be read out for two lines at a time, wherein the amount of smear is made equal at locations above and below a point light source on a screen and a correcting circuit for such smear amount can be constructed in a simplified structure. In the solid-state image pickup apparatus, in a first field, a vertical transferring section is driven, immediately after signal charge has been read out from light sensitive sections, to transfer the signal charge by a two stage distance. But in a second field, immediately before reading of signal charge from the light sensitive sections, the vertical transferring section is driven to effect transfer by a one stage distance and then driven, immediately after such reading of signal charge, to effect transfer by another one stage distance, whereafter it is driven to effect transfer by a two stage distance upon each transferring operation.
