1. An emission controller for an electronic flash associated with an electronic camera which includes both a solid pickup element having individual photoelectric transducer elements which define picture elements of the solid state pickup element, and means for normally repeatedly scanning the transducer element in a predetermined timing sequence;

  • said emission controller comprising;

    (a) means for disabling the scanning means and initializing the individual photoelectric transducer elements by placing each of said transducer elements at a common charge level, prior to the emission of flash light from said electronic flash;

    (b) means for resetting the transducer elements in substantially simultaneous synchronized relationship with the emission of flash light from the electronic flash so as to permit the charge level of each individual transducer element to change as function of the amount of light from the electronic flash impinging on that transducer element; and

    (c) means for enabling the scanning means so as to initiate a sequential scanning of the transducer element at a given time delay after the emission of flash light from the electronic flash.
