ABSTRACT:
A strobe control method is provided for use in an image pick-up system which performs pseudo-frame photography by staggering, for a prescribed short period of time, the timings at which the photoelectric transducers of a first field and the photoelectric transducers of a second field are cleared in solid-state electronic image sensing devices, and staggering, between the first and second fields and for the aforementioned prescribed short period of time, the timings at which electric charges are read from these photoelectric transducers. The strobe control method includes steps of controlling strobe-light emission in such a manner that the start timing of strobe-light emission occurs after the processing for clearing both fields, and forcibly stopping strobe-light emission for a requisite period of time before charge readout timing of the first field.
