ABSTRACT:
An apparatus for driving a solid-state image pickup device for optimizing the transmission timing of a driving signal to be supplied to the image pickup element for adjusting the timing for sample and hold of an output signal from the image pickup element or the like is disclosed which employs a shift register for shifting the driving signal to be supplied to the image pickup element using a clock signal having a relatively shorter period than the period of the driving signal and outputting at its plural stages the driving signals provided with different delay times in increments of one period of the clock signal, and a selection means for selecting a driving signal provided with a desired delay time out of the output signals at the plural stages of the shift register and supplying the selected output signal to the image pickup element, whereby the driving signal can be transmitted at the optimum timing so that the adjustment of the delay time is preformed accurately within a wide range, the shift register can be provided simply and economically, and thus, an apparatus for driving a solid-state image pickup device excellent in that it is economical and requires only a small mount space can be obtained.
