ABSTRACT:
Herein disclosed is a method of reducing the vertical smears which are generated in a solid state image sensor including a plurality of vertical signal lines for transferring signal charges in a vertical direction and at least one charge transfer device for transferring the signal charges in a horizontal direction.
The smear charges stored in the vertical signal lines and the signal charges generated in a photoelectric conversion element in response to an incident ray are inputted separately of each other for a horizontal blanking period to the charge transfer device for the horizontal transfer. During a tracing period, a smear voltage and a signal voltage are outputted separately of each other from said charge transfer device. The smear voltage adjusted is subtracted from the signal voltage to eliminate the smear component which has been mixed into the signal voltage.
