An electric power consumption and a quantity of generated heat can be reduced and hence a temperature characteristic can be maintained satisfactorily. A timing generator generates a smear gate pulse and a storage section driving pulse. The smear gate pulse is supplied to a smear gate region, whereby the smear gate region is opened during a vertical blanking period. The smear gate pulse and the storage section driving pulse are input to a gate circuit and an image section driving pulse is output from the gate circuit. The image section driving pulse has a waveform corresponding to a waveform which results from eliminating a line shift pulse from the storage section driving pulse. In the present invention, since the line shift pulse is not contained in the image section driving pulse, an electric power consumed by an image section is reduced considerably as compared with the prior art. Therefore, a quantity of generated heat also can be reduced, and a temperature characteristic of a frame interline transfer (FIT) solid state image sensor can be maintained satisfactorily.
