Abstract

PURPOSE:To eliminate miss reading of a picture information, by executing subscanning of 1 line volume during a signal charge storage time of a solid state image pickup element, so as to store all the optical information in the solid state image pickup element. CONSTITUTION:When the first transfer gate pulse a1 is sent out, charge which has been stored in the photoelectric conversion part of a CCD image sensor 2 is shifted to the charge transfer register part, further, it is transferred by a charge transfer pulse (c), and is swept out of the sensor 2, but said charge is not converted to a picture signal (d). At the same time, a step pulse (e) is sent out, and subscanning of 1 line volume is executed until the second transfer gate pulse a2 is sent out, that is to say, during just charge storage time t1. Accordingly, all the optical information (b) of the subscanning process of 1 line volume is stored as charge in the photoelectric conversion part of the CCD image sensor 2. Subsequently, when the second transfer gate pulse a2 is sent out, charge which has been stored in the photoelectric conversion part is shifted to the charge transfer register part, and also the picture signal (d) is obtained by the transfer pulse (c).
