An electronic still camera has a stroboscope, a video signal circuit composed of an image pickup element or a charge coupled device, a video signal processing section, an A/D converting section, a timing generator and a frame memory, a trigger timing generator, and a control circuit for controlling operations of the stroboscope, the video signal circuit and the trigger timing generator. A stroboscopic control method used in the electronic still camera has the steps of emitting light from the stroboscope in synchronization with video signals of first and second fields so as to provide an exposure with respect to each of the first and second fields of a frame picture image; and controlling exposure amounts for the first and second fields such that these exposure amounts are equal to each other. A stroboscopic synchronous operation at a frame-recording time is performed by a simplified control mechanism in a state in which there is a difference in time between the first and second fields, thereby performing a reliable exposure.
